Abstract

High effect is attained in reforming of paint for spray painting. Container body (103) of a paint cup (102) consists of a circumferential wall (106) and a bottom wall (107) that form a space for containing paint. The container body (103) includes a holder (108) as a part of the circumferential wall (106). In the holder (108), the same poles of magnets forming each pair of four magnet pairs oppose each other while holding the space for containing paint between them, and the four magnet pairs are arranged such that the opposing poles become identical for all magnets forming the four magnet pairs. More specifically, the four magnet pairs are arranged such that the same poles of all magnets forming the four magnet pairs are directed inward of the container body (103) in the holder (108). When four magnet pairs are arranged in the holder (108) and paint for spray painting is contained in the container body (103), a magnetic field is applied from the four magnet pairs.

Description

Specification

Fluid container, spray coating device, fluid container mounting plate, and spray coating method

Technical field

The present invention relates to a magnetic field application device, a spray coating device, a fluid container, a fluid container mounting plate, a magnetic field application method, and a spray coating method. The present invention particularly relates to a spray coating method and spray coating apparatus used for sheet metal coating and architectural coating of vehicles such as automobiles, and a method and apparatus for improving spray coating paint. It is.

Background art

[0002] There has been conventionally known a modification in which a liquid material for spray injection is exposed to a magnetic field (see, for example, Patent Document 1). In addition, there has been conventionally known a modification in which a liquid in a container is exposed to a magnetic field (see, for example, Patent Documents 2 and 3).

[0003] As a final finish in repairing local damage on a painted surface of a vehicle such as an automobile, sheet metal coating is applied, but spray coating is generally performed. In addition, for surface construction, spray painting using mainly water-based paints (also called “water-based paints”) is also used for surface finish painting. Spray coating is a method in which compressed air that introduces compressor power is mixed with spray paint and sprayed to paint. However, since it is impossible to form a uniform film with a single coating, actual coating is impossible. The work needs to be overcoated. Therefore, it is necessary to repeat the spray painting process and the drying process to form several layers of coating.

[0004] Organic solvent-based paints are used more frequently because they have a shorter drying time than water-based paints! However, when spray coatings are applied, environmental problems such as environmental pollution by solvents and effects on the human body are a concern. Has been. Therefore, research and development of water-based paints has been actively conducted to improve the working environment. However, in the case of aqueous systems, there is a demerit that the uniformity of the coating film in one spray coating is not just the demerit that the time required for the drying process is long. Due to the non-uniformity of the coating film, to obtain a coating film equivalent to the organic solvent system when using aqueous systems For this, it is necessary to make the spray coating more multilayer. For this reason, it takes significantly more work time than organic solvent-based systems, and water-based systems are not being put into practical use.

Problems to be solved by the invention

[0005] Even when a fluid (liquid or gas) is exposed to a magnetic field by a conventional method, there is a problem that the modification effect is not sufficient.

[0006] In the case of water-based paints, the number of times of overcoating is greater than in the case of organic solvent-based paints, so that the time required for spray coating is increased. This difference in the number of times of overcoating is due to the difference in the uniformity of the spray coating film at each time, improving the uniformity and fluidity of the paint immediately before spray coating, and evenly spreading the paint. Being sprayed was a challenge o

BEST MODE FOR CARRYING OUT THE INVENTION

[0031] The inventor has continually worked hard to improve the uniformity of the coating film obtained by spray coating and the fluidity of the paint for spray coating. As a result, it was found that a uniform coating film can be obtained by exposing the paint to a magnetic field having a magnetic field gradient before spray coating, and the number of spray coatings can be greatly improved. It came. Further, the inventor has found an arrangement and a configuration that are particularly high and produce an effect on the magnet used for exposing the paint to a magnetic field, and have reached the present invention.

In the embodiment of the present invention described below, the same effect can be obtained regardless of whether the solvent of the paint for spray coating is water or an organic solvent. The paint for spray coating may contain a coloring pigment or may contain metal fine particles. The main component of the coloring pigment may be an inorganic pigment or an organic pigment. In addition, the coloring pigment may include a magnetic material such as a ferromagnetic material, a ferrimagnetic material, an antiferromagnetic material, a paramagnetic material, and a weak ferromagnetic material, or a non-magnetic pigment, for example, Organic pigments exhibiting diamagnetism may be included. Examples of pigments that exhibit magnetism include pigments that have an acidic property such as transition metals, and aluminum metal fine particles that give metallic luster. Etc. can be used. The same effect can be obtained with a paint made by adding pigments made of organic compounds such as shells and pearls to coloring pigments. The effect of both organic solvent-based and water-based binders is recognized as a paint binder, but especially in the case of water-based binders, it takes longer to dry the paint after spray coating than organic solvent-based binders. The effect of shortening the work man-hour by the invention is increased. Therefore, considering the impact on the environment, it is considered that the social impact of the present invention that is desirable to use the water-based node is great.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0034] Embodiment 1.

FIG. 1 is a perspective view of a spray coating apparatus 100 according to the present embodiment.

In FIG. 1, a spray coating apparatus 100 includes a spray gun 101 and a paint cup 102.

[0036] The spray gun 101 is an example of a spray coating tool. The spray gun 101 sprays the paint contained in the paint force cup 102 by using compressed air to which an air supply device (not shown) such as a compressor is also supplied. Paint is an example of a fluid. As described above, the paint may be a water-based paint or an organic solvent-based paint.

[0037] The paint cup 102 is an example of a fluid container. The paint cup 102 includes a container body 103, a conduit 104, and a lid 105. In the present embodiment, the paint cup 102 is a so-called gravity type and is attached above the spray gun 101. Specifically, a conduit 104 provided on the bottom surface of the paint cup 102 is attached to a joint provided on the side surface of the spray gun 101. At the time of spray coating, the paint contained in the container main body 103 is supplied to the spray gun 101 through the conduit 104 and ejected by the spray gun 101.

FIG. 2 is a perspective view of the paint cup 102.

[0039] The container body 103 of the paint cup 102 also has a force with the peripheral wall 106 and the bottom wall 107, and the peripheral wall 106 and the bottom wall 107 form a space for containing the paint. The container body 103 includes a holder 108 as a part of the peripheral wall 106. The holder 108 is an example of an arrangement member for arranging a plurality of magnet pairs. Multiple magnet pairs are arranged in the holder 108 ヽ When the container body 103 contains a paint for spray coating, a magnetic field is applied to the paint from a plurality of magnet pairs. Thereby, the paint is modified. In the present embodiment, the holder 108 is configured such that the same poles of the magnets forming each pair of the plurality of magnet pairs are opposed to each other with a space for accommodating the paint, and the opposed poles are a plurality of magnets. A plurality of pairs of magnets are arranged so that all pairs of magnets are the same. This makes it possible to obtain a high effect in coating modification.

[0040] The conduit 104 of the paint cup 102 communicates the container main body 103 and the spray gun 101, and conveys the paint contained in the container main body 103 from the container main body 103 to the spray gun 101.

[0041] The lid 105 of the paint cup 102 is screwed or fitted to the upper part of the container main body 103 to cover the upper surface of the container main body 103. The lid 105 may be detachable or may be opened and closed while being fixed to the container body 103.

FIG. 3 is a (a) plan view, (b) a front view, and (c) a bottom view of the holder 108 included in the paint cup 102. 4 is a cross-sectional view taken along line AA in FIG. FIG. 5 is a (a) plan view, (b) front view, and (c) bottom view of the holder 108 when a plurality of magnet pairs are arranged in the holder 108 shown in FIG. 6 is a cross-sectional view taken along line AA in FIG. In FIG. 5, the invisible portion of the magnet 109 forming a plurality of magnet pairs is indicated by a dotted line.

3 to 6, the holder 108 is opposed to each other with the same polarity of the magnets 109 constituting each of four pairs of magnets sandwiching a space for containing the paint. Four magnet pairs are arranged so that all the magnets 109a-h forming one magnet pair are the same. That is, in the holder 108, the four magnet pairs are arranged so that all the magnets 109a to 109h forming the four magnet pairs have the same polarity facing the inner side of the container body 103. Therefore, the holder 108 has holding parts 110a to h for holding the magnets 109a to h by holding the magnets 109a to h with a lower force. The holder 108 may further have a detachable cover to support the magnets 109a-h and to prevent the magnets 109a-h from falling down.

In FIG. 5, a magnet 109 a and a magnet 109 e form a single magnet pair, and are disposed so that the same polarity faces each other with the container body 103 interposed therebetween. Similarly, the magnet 109b and the magnet 109f form one magnet pair, and are disposed so that the same poles face each other with the container body 103 interposed therebetween. Similarly, magnet 109c and magnet 109g form one magnet pair and have the same polarity. The container body 103 is disposed so as to face each other. Similarly, the magnet 109d and the magnet 109h form one magnet pair, and are disposed so that the same poles face each other with the container body 103 interposed therebetween. In each of these four pairs of magnets, the pole facing inward of the container body 103 (that is, the pole facing the space formed by the container body 103) is preferably the S pole. As each magnet 109, for example, a permanent magnet such as a neodymium magnet can be used. Each magnet 109 has a strong magnetic force of 4300 gauss or more, for example.

[0045] The holder 108 has four magnet pairs (that is, magnets 109a to 109h) arranged in an annular shape. Therefore, the holder 108 has a ring shape. In this case, a space for accommodating the paint is formed inside the ring. Furthermore, the holder 108 is preferably provided with magnets 109a to 109h so that adjacent magnets 109 are arranged at equal intervals. Therefore, in the holder 108, for example, in the bottom view of FIG. 5 (c), eight straight lines connecting the center of the ring and the centers of the holding portions 110a to h divide the inner circumference of the ring into eight equal parts. Each holding part 110 is provided at a position. As a result, a magnetic field can be evenly applied to the paint from each of the four magnet pairs. As a result, the effect of modifying the paint is further enhanced. There may be no gap between adjacent magnets 109. That is, the magnets 109a to h may be in close contact with each other. However, the effect of modifying the paint is higher when a certain interval is provided. This is thought to be due to the difference in the shape of the magnetic field lines generated from the four magnet pairs.

FIG. 7 is a (a) side view, (b) plan view, (c) front view, and (d) bottom view of the container body 103 and the conduit 104 provided in the paint cup 102. FIG. 8 is a cross-sectional view taken along line AA in FIG.

7 to 8, the container main body 103 omits the holder 108 that is a part of the peripheral wall 106 and the force that is generated by the peripheral wall 106 and the bottom wall 107. The container main body 103 forms a space for containing paint by an integrally formed cylindrical peripheral wall 106 and a round bottom-shaped bottom wall 107. On the upper surface of the container body 103, an opening for injecting paint is provided. A screw portion 111 for screwing a lid 105 that covers the opening during spray coating is provided on the upper outer side of the peripheral wall 106. A conduit 104 is provided in the lower center of the bottom wall 107 to convey the paint from the container body 103 to the spray gun 101 during spray coating. Conduit 1 At the bottom of 04, even if a support member is provided to prevent the spray coating device 100 from falling down when the spray coating device 100 is placed on a flat surface with the paint cup 102 attached to the spray gun 101, Good.

[0048] As an indication of the size of the paint cup 102, the length of the main part is exemplified below. This embodiment is not limited to the following numerical values. Also, in the same part, the force whose length may not be constant is omitted for details.

(1) Outer diameter of the container body 103: about 80mm

(2) Container body 103 height: about 140mm

(3) Height of the peripheral wall 106 of the container body 103: about 85 mm

(4) Outer diameter of the boundary between the peripheral wall 106 and the bottom wall 107 of the container body 103: about 70 mm

(5) Bottom wall 107 height of container body 103: about 35mm

(6) Inner diameter of conduit 104: about 5mm

(7) Outer diameter of lid 105: about 85mm

(8) Height of lid 105: about 20mm

(9) Outer diameter of holder 108 ring: approx. 85mm

(10) Ring diameter of holder 108: approx. 70mm

(11) Height of holder 108: about 20mm

(12) Width of holder 110 of holder 108: about 10mm

[0049] In the above example, since it is assumed that the holder 108 is fixed near the boundary between the peripheral wall 106 and the bottom wall 107 of the container body 103, the above (4) and (10) are comparable. It is a numerical value

[0050] The container body 103, the conduit 104, the lid 105, and the holder 108 of the paint cup 102 can be formed of plastic such as PO M (polyacetal resin), for example.

3 to 6 are examples of the configuration of the holder 108, and the holder 108 may have other configurations.

[0052] For example, the holder 108 may be provided with the magnet pairs such that all the magnets 109 forming two or three magnet pairs have the same polarity facing the inside of the container body 103. Alternatively, the holder 108 is arranged such that all the magnets 109 forming five or more pairs of magnets face the inside of the container body 103. The magnet pair may be disposed. In this case, the holder 108 has at least as many holding portions 110 as the number of magnets 109 forming the magnet pair.

[0053] For example, the holder 108 may simply be provided with three or more magnets 109 so that all of the magnets 109 face the inside of the container body 103. In this case, the magnet 109 disposed in the holder 108 is directed to a space for accommodating the same-strength paint (that is, a space formed inside the ring of the holder 108). In this case as well, it is desirable that the magnets 109 be disposed in the holder 108 so that the adjacent magnets 109 are arranged at equal intervals.

[0054] For example, the holder 108 may have a holding unit 110 that holds the magnets 109a to h and holds the magnets 109. Alternatively, the holder 108 may be shaped to hold the respective magnet 109 in other ways! The magnets 109a to 109h may be insertable / removable as in the present embodiment, or may be integrally formed with the holder 108 in advance.

In (b) and (c), a holder 108 similar to that shown in FIGS. 3 to 6 can be used. (D) is a form in which three magnet pairs are arranged as in (c), but magnets 109a to 109f are arranged so that adjacent magnets 109 are arranged at equal intervals. (E) shows a magnet with a holder 108 force of 5 magnet pairs 109a ~; j type in which 5 magnet pairs are arranged so that all south poles face each other across the space formed by the container body 103 Is shown. (E) Here, the magnets 109a to j are arranged so that the adjacent magnets 109 are arranged at equal intervals. (F) is a form in which four magnet pairs are arranged as in (a). In addition to the magnets 109a to 109h, a magnet 109i in which the N pole is directed to the space formed by the container body 103 is provided. This magnet 109i is shown in order to give various modified examples of the type in which the force magnet 109, which is essentially unnecessary, is disposed.

In any of (a) to (f) of FIG. 9, the holder 108 is opposed to each other across the space for containing the paint with the same polarity force of the magnets 109 forming each pair of the plurality of magnet pairs. In addition, a plurality of magnet pairs are arranged so that the opposite poles are the same for all the magnets 109 forming the plurality of magnet pairs. As a result, it is possible to obtain a high effect even when the paint is reformed by any of the forms shown in (a) to (f) of FIG.

In FIG. 9, (g) shows a form in which the holder 108 force three magnets 109a to 109c are arranged so that all of the magnets 109a are oriented in the space formed by the container body 103. Yes. In (g), magnets 109a to 109c are arranged so that adjacent magnets 109 are arranged at equal intervals. (H) shows a form in which five magnets 109a to 109e with the force of the holder 108 are arranged so that all of the magnets thereof are directed to the space formed by the container body 103. In (h), the magnets 109a to 109e are arranged so that the adjacent magnets 109 are arranged at equal intervals.

In any of (g) to (h) in FIG. 9, the magnets 109 arranged in the holder 108 are all directed to a space for accommodating the same-polar paint. As a result, it is possible to obtain a high effect in the reforming of the paint by any of the types shown in (g) to (h) of FIG.

[0060] In the present embodiment, the force shown in the drawings for the holder 108 and the container body 103 is actually a part of the peripheral wall 106 of the container body 103. However, the holder 108 may be independent of the container body 103. That is, the holder 108 may be detachable. Therefore, for example, a locking piece for locking the holder 108 may be provided on the peripheral wall 106 of the container body 103.

[0142] Embodiment 6.

18 to 19 are perspective views of a plate 600 according to the present embodiment. FIG. 18 shows a state where the paint container 602 is placed on the plate 600. FIG. 19 shows a state where the paint container 602 is placed on the plate 600.

In FIG. 18, a paint container 602 is an example of a fluid container. The paint container 602 contains paint for spray painting. The force on the paint container 602 with the handle 619 is not essential. A paint is an example of a fluid. As described above, the paint may be a water-based paint or an organic solvent-based paint.

18 to 19, a plate 600 is an example of a fluid container mounting plate. The plate 600 includes a bottom plate 605, a plurality of magnet pairs, and a cover 608.

[0145] The bottom plate 605 of the plate 600 includes a bottom plate body 615 and a support portion 616. The bottom plate body 615 is for placing the paint container 602 thereon. The support portion 616 is erected above the bottom plate body 615 and supports the cover 608.

[0146] The plurality of magnet pairs are for applying a magnetic field to the paint. The cover 608 of the plate 600 is an example of an enclosing member, and is for enclosing the paint container 602. The cover 608 is attached to the upper portion of the support portion 616 of the bottom plate 605. The cover 608 is an example of a disposing member that disposes a plurality of magnet pairs. Multiple magnet pairs are installed on the cover 608. When the paint container 602 containing the paint for spray coating is placed on the bottom plate 605, a magnetic field is applied to the paint in the form of a plurality of magnet pairs. As a result, the paint is modified. In the present embodiment, when the paint container 602 is placed on the bottom plate 605, the cover 608 has the same polarity of the magnets 609 forming each pair of the plurality of magnet pairs facing each other with the paint container 602 interposed therebetween, and The magnet pairs 609a-h (the magnets 609e-h are not shown in FIGS. 18-19) are the same so that the opposing poles form a plurality of magnet pairs. Thereby, it is possible to obtain a high effect in reforming the paint contained in the paint container 602.

[0147] If the paint container 602 containing the paint is placed on the bottom plate 605 of the plate 600 for several seconds or at most several minutes, the paint is modified. After that, if the paint is transferred to the paint cup, and the paint cup is attached to the spray gun and sprayed, spray coating using the modified paint can be performed. At this time, the spray gun sprays the modified paint contained in the paint cup by using compressed air supplied by an air supply such as a compressor.

[0148] In the present embodiment, the bottom plate 605 of the plate 600 is provided with a magnetic field generating member. A bottom plate cover 617 is attached on the magnetic field generating member. When a plurality of magnet pairs are disposed on the plate 600 608 of the plate 600 and a magnetic field generating member is disposed on the bottom plate 605 of the plate 600, paint for spray coating is accommodated on the bottom plate 605. When the paint container 602 is placed, a magnetic field is applied to the paint not only from a plurality of magnet pairs but also from a magnetic field generating member. Thereby, it is possible to obtain a higher effect in the modification of the paint. When the magnetic field generating member is disposed on the bottom plate 605, a certain effect can be obtained even if a plurality of magnet pairs are not disposed on the cover 608.

FIG. 20 shows (a) a plan view, (b) a rear view, and (c) a bottom view of a cover 608 included in the plate 600. FIG. 21 is a cross-sectional view taken along the line AA in FIG. FIG. 22 is a (a) plan view, (b) rear view, and (c) bottom view of the cover 608 when a plurality of magnet pairs are disposed on the cover 608 shown in FIG. 23 is a cross-sectional view taken along line AA in FIG. In FIG. 22, the invisible portion of the magnet 609 forming a plurality of magnet pairs is indicated by a dotted line.

[0150] In FIGS. 20 to 23, Kanokuichi 608 is used when the paint container 602 is placed on the bottom plate 605. The same polarity force of magnets 609 forming each pair of four magnet pairs is opposed to each other across the paint container 602, and all the magnets 609a to 609h forming the opposite magnet pairs as much as possible are the same. Two magnet pairs are arranged. In other words, the Kanoko 1 608 has four magnet pairs arranged so that all the magnets 609a-h forming the four magnet pairs have the same polarity facing the direction of the paint container 602. Therefore, Kanokichi 608 has insertion holes 618a-h for inserting the respective magnets 609.

In FIG. 22, a magnet 609a and a magnet 609e constitute one magnet pair, and are disposed so that the same poles face each other with the coating container 602 interposed therebetween. Similarly, the magnet 609b and the magnet 609f form one magnet pair, and are disposed so that the same poles face each other with the paint container 602 interposed therebetween. Similarly, the magnet 609c and the magnet 609g form one magnet pair, and are disposed so that the same polarity faces each other with the coating container 602 interposed therebetween. Similarly, the magnet 609d and the magnet 609h form a single magnet pair, and are disposed so that the same polarity faces each other with the paint container 602 interposed therebetween. In each of these four magnet pairs, the pole facing the paint container 602 (that is, the pole facing the space surrounded by the cover 608) is preferably the S pole. As each magnet 609, for example, a permanent magnet such as a neodymium magnet can be used. As each magnet 609, for example, a magnet having a strong magnetic force of 4300 gauss or more is preferably used.

[0152] The cover 608 has four pairs of magnets (ie, magnets 609a to 609h) arranged in a ring shape. The cover 608 is preferably provided with magnets 609a to 609h so that adjacent magnets 609 are arranged at equal intervals. At least a part of the space surrounded by the cover 608 forms a space for storing the paint (that is, a space in which the paint container 602 is disposed). For example, as shown in FIG. 19, the cover 608 does not have to surround the paint container 602 360 degrees. For example, the force bar 608 may be shaped to enclose the paint container 602 about 335 degrees. Accordingly, the force depending on the size of the paint container 602 makes it easy to place the paint container 602 with the handle 619 as shown in FIG.

FIG. 24 shows (a) a plan view, (b) a rear view, and (c) a bottom view of a bottom plate 605 included in the plate 600. FIG. 25 is a cross-sectional view taken along the line AA in FIG. 26 shows (a) a plan view, (b) a rear view, and (c) a bottom view of the bottom plate 605 when a magnetic field generating member is disposed on the bottom plate 605 shown in FIG. FIG. FIG. 26 is a cross-sectional view taken along line AA in FIG. In FIG. 25, the invisible portion of the magnet 612 constituting the magnetic field generating member is represented by a dotted line.

In FIGS. 24 to 26, the bottom plate 605 includes poles of the magnets 612a to 612b constituting the magnetic field generating member when the paint container 602 is placed, and a pair of four magnets that are directed to the paint container 602. The magnetic field generating member is disposed so that the poles facing each other with the paint container 602 of the magnet 609 forming a pair are the same. That is, the bottom plate 605 is composed of the magnets 612a to 612b constituting the magnetic field generating member and the poles facing the direction of the paint container 602 (that is, upward), and the magnets 609a to h that form four magnet pairs. Arrange the magnetic field generating members so that the force is the same as the poles facing in the direction. The bottom plate 605 has a detachable bottom plate cover 617 for covering the magnets 612a-b on the upper surface thereof.

In FIGS. 24 to 26, magnets 612a and 612b constitute a magnetic field generating member, and are the same as the poles facing each other across the paint container 602 in each pair of four magnet pairs disposed on the cover 608. The pole is disposed so as to face upward. In this magnetic field generating member, the pole facing upward (that is, the pole pointing in the space surrounded by the cover 608) is preferably the S pole. As each magnet 612, it is desirable to use different types of permanent magnets for the force magnet 612a and the magnet 612b, which can use permanent magnets. For example, a neodymium magnet can be used as the magnet 612a, and a ferrite magnet can be used as the magnet 612b. Also, it is desirable that the magnet 612a be circular and the magnet 612b be ring-shaped so that the magnet 612a can be fitted into the inner peripheral surface of the ring of the magnet 612b. As each magnet 612, it is desirable to use a magnet having a strong magnetic force of, for example, 4300 gauss or more.

[0156] As an indication of the size of the plate 600, the length of the main part is illustrated below. The present embodiment is not limited to the following numerical values. In addition, in the same part, the length may not be constant, but details are omitted.

(1) Outer diameter of bottom plate 605 support 616: about 170mm

(2) Inner diameter of support 616 of bottom plate 605: about 140mm

(3) Height of support 616 of bottom plate 605: about 40mm

20 to 23 show an example of the configuration of the cover 608, and the Kanoko 608 may have other configurations.

[0159] For example, when the paint container 602 is placed on the bottom plate 605, the cover 608 is arranged so that all the magnets 609 forming three or more magnet pairs have the same polarity facing the direction of the paint container 602. Pairs may be provided. For example, the kanoku 608 may simply be arranged with three or more magnets 609 such that all of the magnets 609 face the direction of the paint container 602. In this case, the magnet 609 disposed in the cover 608 points to a space for containing the same polar paint as much as possible. Also in this case, the cover 608 is preferably provided with the magnets 609 so that the adjacent magnets 609 are arranged at equal intervals. As shown in FIG. 9 in the first embodiment, the form in which the Kanokoku 608 force S magnet 609 in FIG. 22 is arranged can be changed to various forms. Magnets 609a-h may be detachable as in the present embodiment, or may be integrally formed with cover 608 in advance.

[0161] For example, the bottom plate 605 may be provided with a plurality of magnetic field generating members. For example, the magnetic field generating member may be one magnet 612. Alternatively, the magnetic field generating member may be three or more magnets 6 12. The magnets 612a to 612b may be detachable, or may be preliminarily molded with the bottom plate 605. When the magnets 612a-b are integrally formed with the bottom plate 605, the bottom plate cover 617 is not necessary. [0162] As described above, in the present embodiment, plate 600 includes bottom plate 605, a plurality of magnet pairs, and cover 608. The bottom plate 605 is for placing a paint container 602 for containing paint for spray coating. The plurality of magnet pairs are for applying a magnetic field to the paint. The cover 608 surrounds the paint container 602, and when the paint container 602 is placed on the bottom plate 605, the same polarity of the magnets 609 forming each pair of a plurality of magnet pairs is the paint container. A plurality of magnet pairs are arranged so as to face each other across 602 and so that the opposing poles are the same in all of the magnets 609 forming the plurality of magnet pairs.

[0163] The plate 600 further includes a magnetic field generating member. The magnetic field generating member is for applying a magnetic field to the paint for spray coating. When the paint container 602 is placed, the bottom plate 605 is provided with the paint container 602 of the magnet 609 that forms a pair of a pole that faces the paint container 602 of the magnetic field generating member (that is, the magnet 612) and a plurality of magnet pairs. The magnetic field generating member is arranged so that the poles facing each other are the same.

[0164] This embodiment realizes a magnetic field applying device that applies a magnetic field to a paint in order to modify the paint. The magnetic field application apparatus according to the present embodiment includes a plurality of magnet pairs and a plate 600.

[0165] According to the magnetic field application apparatus according to the present embodiment, a high effect can be obtained in the modification of the paint.

The present embodiment realizes a magnetic field application method for applying a magnetic field to a paint in order to modify the paint. In the magnetic field application method according to the present embodiment, the magnets 609 forming each pair of a plurality of magnet pairs are opposed to each other across a space for accommodating paints, and there are a plurality of the facing poles. A plurality of magnet pairs are arranged so that all the magnets 609 forming the magnet pair are the same (arrangement step of a plurality of magnet pairs), and a plurality of magnets arranged by the arrangement step of the plurality of magnet pairs. Using a pair, a magnetic field is applied to the paint. Further, the magnetic field generating member is arranged so that the poles directed to the space of the magnetic field generating member and the poles facing the space of the magnet 609 forming each pair of a plurality of magnet pairs are the same. (Magnetic field generating member disposing step), a magnetic field is applied to the paint using the magnetic field generating member disposed in the magnetic field generating member disposing step.

[0167] According to the magnetic field application method according to the present embodiment, a high effect is obtained in the modification of the paint. Can be obtained.

[0168] This embodiment realizes a spray coating method using a modified paint. The spray coating method according to the present embodiment surrounds the paint container 602, a bottom plate 605 for placing the paint container 602 for containing the paint, a plurality of magnet pairs for applying a magnetic field to the paint, and the paint container 602. When the paint container 602 is placed on the bottom plate 605, the same polarity of the magnets 609 constituting each pair of the plurality of magnet pairs face each other with the paint container 602 interposed therebetween, and The paint container 602 is placed on the plate 600 including the cover 608 on which the plurality of magnet pairs are arranged so that the opposing poles are the same for all of the magnets 609 forming the plurality of magnet pairs (loading of the fluid container). Placing step), using a spray gun, spraying the paint contained in the paint container 602 placed on the plate 600 in the fluid container placing step by spraying.

[0169] According to the spray coating method of the present embodiment, it is possible to improve the work environment of spray coating. For example, even when using water-based paints, not only when using organic solvent-based paints, it is possible to obtain spray coating uniformity, reduce the time that the spray painter is exposed to the spray mist, and The work time can be shortened.

[0170] In the present embodiment, the plate 600 has been described as being for placing the paint container 6002 containing the paint for spray coating. However, the plate 600 can be used for various fluids other than paint.

[0171] For example, if a flower and a container such as a vase are placed on the plate 600 for several minutes, the flower will die. In addition, flower growth may be promoted. This is thought to be due to the modification of the water contained in the flowers and the water contained in the container such as the vase.

[0172] For example, if a liquid such as drinking water or liquor is placed on the plate 600 for several minutes together with a container such as a cup, the taste of the liquid changes. In addition, the taste of the liquid may be improved. This is thought to be due to the modification of liquids such as drinking water and liquor as fluids.

[0173] For example, if food is placed in a container or directly on the plate 600 for several minutes, The food will rot. As a result, food shelf life is improved. This is thought to be due to the modification of the moisture contained in the food as a fluid.

[0179] Embodiment 7.

The difference between the present embodiment and the sixth embodiment will be mainly described.

[0180] In Embodiment 6, when the paint container 602 is placed, the bottom plate 605 is a pole of the magnets 612a to 612b constituting the magnetic field generating member and is directed to the paint container 602 and four magnet pairs. The magnetic field generating member is arranged so that the poles facing each other with the paint container 602 of the magnet 609 forming a pair of the magnet 609 are the same. On the other hand, in the present embodiment, when the paint container 602 is placed, the bottom plate 605 is a pole of the magnets 612a to 612b constituting the magnetic field generating member and is directed to the paint container 602, and four magnet pairs. The magnetic field generating members are arranged so that the poles facing each other with the paint container 602 of the magnets 609 forming the pairs are different. For example, in each of four pairs of magnets disposed on the cover 608, when the pole facing the paint container 602 (that is, the pole facing the space surrounded by the cover 608) is the S pole, the magnetic field In the generating member, the magnetic field generating member is arranged so that the pole facing upward (that is, the pole facing the space surrounded by the cover 608) becomes the N pole. Other configurations of the plate 600 are the same as those described in the sixth embodiment. In the present embodiment, when the paint container 602 containing the paint for spray coating is placed on the plate 600 immediately before spray coating, the following phenomenon occurs, and a magnetic field is applied to the paint.

[0182] First, lines of magnetic force appear from the bottom plate 605 of the plate 600 upward (ie, in the direction of the paint container 602) vertically (or nearly perpendicular). The magnetic flux density Φ increases as the distance from the bottom plate 605 increases. The magnetic field gradient generated in the bottom plate 605 is such that the N pole is oriented perpendicular to the bottom plate body 615 (i.e., the angle between the magnetic field lines applied to the paint container 602 and the top surface of the bottom plate body 615 is 90 degrees or 90 degrees). Formed by a magnetic field generating member (ie, magnets 612a to 612b) disposed so as to be close to each other. Here, the case where the N pole is on the top surface of the magnetic field generating member is shown, but the same effect can be obtained even if the top surface is the S pole. In addition, the magnetic field generating member is arranged so that the major axis with both ends of the N and S poles of the magnetic field generating member is parallel to the upper surface of the bottom plate body 615 and the N or S pole is opposite. In addition, it is possible to generate a magnetic field perpendicular to the upper surface of the bottom plate body 615. Due to this magnetic field gradient, the pigment or Z and fine metal particles in the paint are drawn to the bottom plate body 615 having a large magnetic flux density Φ along the magnetic field lines generated immediately after the paint is placed on the bottom plate 605 of the plate 600. It is done. Therefore, the paint is convectively stirred on the bottom plate 605. There are no restrictions on the arrangement, number, and magnitude of the magnetic field generating members for forming the magnetic field. It is desirable that the magnetic field generating member can be accommodated in the bottom plate 605 in a compact manner. The magnetic field generating member is preferably composed of a magnet 612 that generates a stronger magnetic field because stirring can be completed in a shorter time as the magnetic field is larger.

As described above, when the magnetic field generating member is arranged at the center of the bottom plate 605 so that the top surface of the bottom plate body 615 becomes the north pole, the magnetic lines of force are generated perpendicularly to the top surface of the bottom plate body 615. This magnetic field line returns to the magnets 609a to 609h disposed on the cover 608 of the plate 600. Here, the magnets 609a to h are installed so that the magnetic pole of the surface facing the inner side of the plate 600 becomes the S pole which is the opposite pole of the magnetic field generating member installed in the center of the bottom plate 605. When the top surface of the magnetic field generating member is the south pole, the magnets 609a to h are installed so that the surface of the magnet 609a to h facing the inside of the plate 600 becomes the north pole.

[0184] In the present embodiment, the lines of magnetic force directly act on the fine particles of the pigment, which is a component of the paint. Thus, since the paint is agitated, a remarkable effect can be obtained (that is, the agitation efficiency is good) as compared with the effect obtained when the paint is agitated with a commonly used spatula. As a result, the uniformity of the paint can be secured, and if the uniformity of the spray-coated film is improved, it is possible to obtain the effect!

[0185] According to the magnetic field application apparatus according to each of the above embodiments, the particles contained in the paint for spray coating can be made uniform or subdivided. In other words, the paint can be modified. When the coating material thus modified is used, the following effects can be obtained.

'It becomes possible to paint with the air pressure of the spray gun reduced. As a result, the paint becomes difficult to disperse in the air, and the amount of paint used is reduced.

'The coating rate is improved and the finish of the painted surface is improved. As a result, the quality of the finished product does not vary greatly depending on the individual skill level of the sprayer. That is, a uniform finish can be achieved.

• As a result of the above, work efficiency is further improved.

• As a result of the above, work time is further reduced.

• As a result, the cost is further reduced.

[0190] Hereinafter, experimental results regarding the above-described embodiment of the present invention will be shown.

[0191] In the following Experiments 1 to 4, a spray coating experiment as shown in FIG. 28 was conducted.

[0192] First, as shown in Fig. 28 (a), the entire black iron plate was spray-painted (this is called "the first painting"). Next, as shown in Fig. 28 (b), out of the area where the iron plate was divided into three equal parts, area A was masked and area B and area C were spray-painted (this is called "second coating"). U) Finally, as shown in Fig. 28 (c), area B was masked in addition to area A, and area C was spray-coated (this is called "third coating"). In Fig. 28, the shaded area indicates masking.

[0193] Experiment 1.

In this experiment, an iron plate was spray-coated using the spray coating apparatus 100 described in the first and second embodiments.

[0194] In this experiment, AQUAS made by Isamu Paint Co., Ltd. was used as a water-based paint for spray painting.

(Registered trademark) · Metallic details were used. The standard spray method (spray pattern (spreading width): fully open, spraying amount: 2 rotations, air pressure: 1.8 kg) is used, and the paints according to the embodiments 1 and 2 are used. The paint was applied under exactly the same conditions when the paint was put into the cup 102 and when the paint was put into the conventional paint cup. The weather on the experiment day was cloudy with a maximum temperature of 27 degrees Celsius, a minimum temperature of 21.7 degrees Celsius, and a humidity of 78%.

[0195] As described above, spray coating and drying were repeated three times to obtain 1 layer (region A), 2 layer (region B) and 3 layer (region C) coating films. As a result of this experiment, the following five types of painted surfaces PS (a) to (e) were obtained.

[0196] PS (a) puts paint in a conventional paint cup (ie, paint cup not including holder 108, magnet 109, magnet 112), attaches the paint cup to spray gun 101, and sprinkles the iron plate. This is the result when lah is applied. PS (b) is a paint cup 102 in which a magnet 109 is arranged in a holder 108 in the same manner as in FIG. 9 (a) (that is, the holder 108 has all the S poles of the magnets 109a to 109h forming four magnet pairs). When paint is put in a paint cup (102) with four magnet pairs arranged so as to face each other across the space formed by the container body 103, the paint cup 102 is attached to the spray gun 101, and the iron plate is spray painted Is the result of PS (c) is the result when the magnets 112a to 112b are also arranged on the lid 105 of the paint cup 102 used for PS (b). In the case of PS (c), the magnets 112a to 112b are arranged so that the south pole (that is, the same pole as the magnets 109a to h) faces the inside (that is, the lower side) of the paint cup 102. PS (d) reverses the magnetic poles of the magnet 109 placed on the holder 108 of the paint cup 102 used in PS (b) (ie, the holder 108 has four magnet pairs 109a to h for all N). This is a result in the case where two magnet pairs are arranged so that the poles face each other across the space formed by the container body 103. PS (e) is the result when magnets 112a-b are also arranged on lid 105 of paint cup 102 used for PS (d). In the case of PS (e), in any of the magnets 112a to 112b, the N pole (that is, the same polarity as the magnets 109a to h) is disposed so as to face the inside (that is, the lower side) of the paint cup 102.

[0197] The steel plates of PS (a) to (e) are divided into three equal parts from bottom to region A, region B, and region C. o PS (a) to (e) a), PS (d), PS (e), PS (b), PS (c) t ヽぅ It was clear that the finish of the coating was good. For example, the iron plate of PS (a) was almost the original color only by the first painting, but the iron plate of PS (b) was almost stiff by the first painting. The coating became thicker (ie, the uniformity of the coating was high).

[0198] Experiment 2.

In this experiment, the number of magnets 109 when putting paint into the paint cup 102 according to Embodiments 1 and 2 was reduced to four, and, similar to Experiment 1, spraying and drying were repeated three times. A coating of layers (region A), two layers (region B) and three layers (region C) was obtained. As a result of this experiment, the following five types of painted surfaces PS (f) to (j) were obtained.

[0199] PS (f) puts paint in a conventional paint cup (ie, a paint cup that does not include the holder 108, magnet 109, and magnet 112), attaches the paint cup to the spray gun 101, and sprays the iron plate. This is the result when one paint is applied. PS (g) is a paint cup 102 in which magnet 109 is arranged in holder 108 in the same manner as in FIG. 9 (b) (ie, holder 108 force magnets 10 9a-d all S poles of two magnet pairs). The paint cup 102) in which two magnet pairs are arranged is placed so as to face each other across the space formed by the container body 103, the paint cup 102 is attached to the spray gun 101, and the iron plate is spray-coated. Is the result of the case. PS (h) is the result when the magnets 112a-b are also arranged on the lid 105 of the paint cup 102 used for PS (g). In the case of PS (h), the magnets 112a to 112b are arranged so that the south pole (that is, the same pole as the magnets 109a to 109d) faces the inside (that is, the lower side) of the paint cup 102. PS (i) is the reverse of the magnetic pole of the magnet 109 arranged in the holder 108 of the paint cup 102 used for PS (g) (i.e., the holder 108 force of the magnet 109a-d all N poles forming two magnet pairs). Is the result when two magnet pairs are arranged so as to face each other across the space formed by the container body 103. PS (j) is the result when the magnets 112a to 112b are also arranged on the lid 105 of the paint cup 102 used for PS (i). In the case of PS (j), all of the magnets 112a to 112b are arranged so that the N pole (that is, the same pole as the magnets 109a to 109d) faces the inside (that is, the lower side) of the paint cup 102.

[0200] When comparing the steel plates of PS (f) to (j), it was found that almost the same results as in Experiment 1 were obtained. For example, the PS (f) iron plate remained almost the original color only by the first coating, but the PS (g) iron plate was almost unaffected by the first coating alone. The coating became thicker (ie, the uniformity of the coating was high).

[0201] As described above, according to Experiments 1 and 2, according to the spray coating apparatus 100 according to Embodiments 1 and 2, when water-based paint is used, the spray coating operator obtains the uniformity of spray coating and the spray coating operator performs spraying. It was confirmed that the exposure time during spraying can be reduced and the time required for spray coating can be shortened. In the experiment, it was confirmed that the odor of the coating film decreased when the spray coating apparatus 100 was used.

[0202] Experiment 3.

In this experiment, using Isakuro Paint Co., Ltd.'s acrobase mitaribrite as an organic solvent-based paint for spray painting, the same three experiments as in Experiment 1 were repeated, followed by one layer (area). A), 2 layers (region B) and 3 layers (region C) were obtained. Results of this experiment and Thus, the following five types of painted surfaces PS (k) to (o) were obtained.

[0203] PS (k) puts paint in a conventional paint cup (ie, paint cup not including holder 108, magnet 109, magnet 112), attaches paint cup to spray gun 101, and sprays iron plate This is the result. PS (1) is a paint cup 102 in which a magnet 109 is arranged in a holder 108 in the same manner as in FIG. 9 (a) (that is, the holder 108 has all the S poles of the magnets 109a-h forming four magnet pairs). When paint is put in a paint cup (102) with four magnet pairs so as to face each other across the space formed by the container body 103, the paint cup 102 is attached to the spray gun 101, and the iron plate is spray-coated Is the result of PS (m) is the result when the magnets 112a to 112b are also arranged on the lid 105 of the paint cup 102 used for PS (1). In the case of PS (m), the magnets 112a to 112b are arranged so that the south pole (that is, the same pole as the magnets 109a to h) faces the inner side (that is, the lower side) of the paint cup 102. PS (n) reverses the magnetic poles of the magnet 109 arranged in the holder 108 of the paint cup 102 used in PS (1) (that is, the holder 108 has four magnet pairs 109a to h of all N). This is a result in the case where two magnet pairs are arranged so that the poles face each other across the space formed by the container body 103. PS (o) is the result when magnets 112a-b are also arranged on lid 105 of paint cup 102 used for PS (n). In the case of PS (o), any of the magnets 112a to 112b is arranged so that the N pole (that is, the same pole as the magnets 109a to h) faces the inner side (that is, the lower side) of the paint cup 102.

[0204] When comparing the steel plates of PS (k) to (o), PS (k), PS (n), PS (o), PS (1), PS (m) and so on! I was able to understand that I was getting better. For example, the PS (k) iron plate remained almost the original color only by the first coating, but the PS (1) iron plate was almost unaffected by the original coating alone. The coating became thicker (that is, the uniformity of the coating was high).

[0205] Experiment 4.

In this experiment, the number of magnets 109 when putting paint in the paint cup 102 according to Embodiments 1 and 2 was reduced to four, and, similar to Experiment 3, spray painting and drying were repeated three times. A coating of layers (region A), two layers (region B) and three layers (region C) was obtained. As a result of this experiment, the following five types of painted surfaces PS (p) to (t) were obtained. [0206] PS (p) puts paint in a conventional paint cup (ie, paint cup not including holder 108, magnet 109, magnet 112), attaches paint cup to spray gun 101, and sprays steel plate. This is the result. PS (q) is a paint cup 102 in which a magnet 109 is arranged in the same manner as in FIG. 9 (b) in the holder 108 (that is, the holder 108 has all the south poles of the magnets 109a to 109d forming two magnet pairs). When paint is put in a paint cup (102) with two magnet pairs arranged so as to face each other across the space formed by the container body 103, the paint cup 102 is attached to the spray gun 101, and the iron plate is spray-coated Is the result of PS (r) is a result when the magnets 112a to 112b are also arranged on the lid 105 of the paint cup 102 used for PS (q). In the case of PS (r), the magnets 112a to 112b are arranged so that the south pole (that is, the same pole as the magnets 109a to 109d) faces the inside (that is, the lower side) of the paint cup 102. PS (s) is the reverse of the magnetic pole of the magnet 109 placed on the holder 108 of the paint cup 102 used for PS (q) (that is, the magnet 109a-d of all magnets 109a-d that form two magnet pairs) Is a result of the case where two magnet pairs are arranged so as to face each other across the space formed by the container body 103. PS (t) is a result when the magnets 112a to 112b are also arranged on the lid 105 of the paint cup 102 used for PS (s). In the case of PS (t), all of the magnets 112a to 112b are arranged so that the N pole (that is, the same pole as the magnets 109a to 109d) faces the inside (that is, the lower side) of the paint cup 102.

[0207] When the steel plates of PS (p) to (t) were compared, it was found that almost the same results as in Experiment 3 were obtained. For example, the iron plate of PS (p) was almost the original color only by the first painting, but the iron plate of PS (q) was almost unaffected by the original painting. The coating became thicker (ie, the uniformity of the coating was high).

As described above, according to Experiments 3 to 4, according to the spray coating apparatus 100 according to Embodiments 1 to 2, even when an organic solvent-based paint is used, the spray coating uniformity is obtained and It has been confirmed that it is possible to reduce the exposure time during spray spraying and to shorten the spray painting work time. In addition, in the experiment, it was confirmed that the odor of the coating film decreased when the spray coating device 100 was used.
