Description

Super paper for gypsum board seam and method and apparatus for manufacturing same {lining paper for joint of plaster board, method and apparatus of making the lining paper for joint of plaster board}

The present invention relates to a super medium for gypsum board seam and a method and apparatus for manufacturing the same.

In the interior of the building, various shapes and materials are used for aesthetics. Background surfaces such as walls or ceilings in a room are usually made of concrete, plasterer, or plasterboard. If the broth immediately lands on the concrete or plaster base, the broth tends to lift off easily from the concrete or plaster base. In addition, as shown in FIG. 1, when the paper 2 is directly applied to the seam of the gypsum board base surface 1, the shape of the gypsum board seam may be displayed on the paper 2 to damage the aesthetics.

Therefore, in order to prevent the above-mentioned drawbacks, it is common to apply a paper medium on the base surfaces first and then to apply a paper medium on it.

The super medium is usually manufactured in a paper mill in which raw materials such as cotton, hemp, recycled paper, and the like are put into a paper production furnace, molded and dried, and then wound on a roll (this is referred to as "fabric of super medium"). The fabric of the super medium thus produced is cut according to the above-described method of construction. The cut super badge is cut by a predetermined length and stored and used in a state of being wound in a roll-shaped bar or the like.

If the part of the super medium is a concrete or plastering base surface is overlapped by 10mm or more overlapping joints, in the case of a gypsum board base surface, a super medium (3) of about 10 cm in width is supercritical. The papering work is completed by papering the paper on the drafted paper.

However, the cut sheet of the super medium has a substantially vertical shape, and the super medium 3 of which the stage is extended is used. Therefore, when the super badge is superimposed with overlapping joints, the overlapping portion protrudes more than the non-overlapping portion, and when the paper sheet is dominated, the overlapping portion protrudes, which may greatly damage the aesthetics.

On the other hand, as shown in Figure 2, when a high-quality wallpaper paper 2 'such as silk wallpaper or laminated wallpaper is used for the gypsum board base surface (1), the stage that is greeted with gypsum board seams (3) By protruding from the part of), it may occur when you have to do the paper again. Therefore, when a high-quality wall paper is used, such as a hotel, an additional operation is performed to grind the portion of the stepped grass paper 3, which is made to the seam of the gypsum board, using sand paper or the like to smooth the slope.

As such, there is a problem in that the work environment is poor due to the sand paper work and the construction time increases greatly, resulting in poor workability and economic efficiency.

In addition, since the thickness of the edge portion of the super medium is reduced by manual labor, the uniform state of the paper medium may be poor because the thickness of the edge portion of the super medium may not be uniform.

On the other hand, when foreign matter is formed during the manufacturing process of the super medium, the adsorption of the grass is weak, so that the bonding force between the base surface and the super medium of the gypsum board tends to be easily lifted.

In general, the edge of the super medium formed from a single web is pasted and solidified in use. Therefore, the solidified grass is painted to loosen the water at this time, the surface tension may occur as the water dries may cause the initial medium to squiggle.

The present invention has been made to solve the above-described problems, by providing a method of producing a gypsum board seam super medium to increase the efficiency of the work by economically produced by sand blasting so that the thickness of the edge is formed thinner than the thickness of the center portion. It is.

Another object of the present invention is to provide a gypsum board seam super medium, which is formed by laminating webs of different widths, the thickness of which is simply thinner than the thickness of the central portion.

It is still another object of the present invention to provide a method and apparatus for manufacturing a gypsum board seam medium by using a mesh of cylinder molds of different lengths, which makes it possible to produce a super medium whose thickness is thinner than that of the center portion.

Another feature of the present invention comprises a first web having a predetermined width, and a second web wider than the width of the first web, the first web and the second web is laminated gypsum board for It is a super badge.

Another feature of the present invention is to install a cylinder mold in the pulp tank in the apparatus for producing a super medium, the cylinder mold is a first cylinder mold and a second cylinder each having a mesh body formed on the outer peripheral surface of the cylinder body and the cylinder body Including the mold, the length of the mesh of the first cylinder mold is formed shorter than the length of the mesh of the second cylinder mold.

According to another aspect of the present invention, there is provided a method of forming a first web in a blanket running between a first cylinder mold passing through a first pulp tank and a first compression roller, and the blanket on which the first web is formed is a second pulp. And a second web, which is wider than the width of the first web, is laminated with the first web when passing between the second cylinder mold passing through the tank and the second compression roller.

Hereinafter, with reference to the accompanying drawings, a gypsum board seam super medium, and a method and apparatus for manufacturing the same according to the preferred embodiment of the present invention will be described in detail. The term "laminated paper" used in the present specification and claims has a width. It is defined that different webs overlap one another and are created integrally.

Example 1

3 is an enlarged longitudinal cross-sectional view showing a gypsum board seam super medium according to the first embodiment of the present invention, Figure 4 is a longitudinal cross-sectional view showing a state using the super medium of FIG. As shown in Fig. 3 and Fig. 4, the super medium 30 of the first embodiment is thinner at both edges than the central portion of the width.

When the super medium 30 is superimposed on the gypsum board base surface 1 and plated with the paper medium 2 (2 ') thereon, as shown in FIG. 4, the protruding state of the paper medium 2 (2') is It is almost gentle and can be made entirely flat.

Hereinafter, a method of manufacturing the super medium 30 of the above-described first embodiment is as follows.

FIG. 5 is a configuration diagram schematically illustrating a process of manufacturing the super badge of Example 1, and FIG. 6 is a process diagram of FIG. 5. As shown in Figures 5 and 6, the manufacturing method of the gypsum board seam super medium according to the present embodiment, as described above, first supply the fabric 10 of the super medium provided in the form of a roll.

The super medium fabric 10 of the present invention is produced while passing the apparatus described below by a plurality of feed rollers (not shown). That is, the fabric 10 of the super medium passes through the cutter 12 first. The fabric 10 of the super badge is cut into two or more hems while passing through the cutters 12 provided at regular width intervals, for example, widths of 10 cm. The number of hem of the fabric of the super medium to be cut depends on the number of installed cutters 12. For example, when two cutters 12 are installed as shown in FIG. 5, the fabric 10 is cut into three hems.

A feature of the present invention is to cut the cut super badge immediately by a certain length, the sand blasting process of the cutting surface of the super medium, as shown in Figure 3 tapered shape, that is, the shape is reduced in thickness toward the edge of the super medium as shown in FIG. To be. Such a tapered shape depends on the injection distance, injection pressure and injection position of the nozzle 14 described later, but is preferably formed in a concave shape. Such concave shape is intimately adhered to the gypsum board base surface 1 even if it is superbly made without distinguishing front and back, so that a step is not formed.

The sand blasting treatment uses a sand blasting machine which is usually used for surface treatment. The sand blasting machine is a machine that sprays a projectile, such as sand or sandpaper abrasive, contained in a pressurized tank from the nozzle 14 through a hose to impinge on the surface of a workpiece by using compressed air. In addition, an impeller sandblasting machine using centrifugal force instead of compressed air may be used.

The injection distance of the upper cutting surface of the super medium and the nozzle 14 for sand blasting is 10 to 15 cm, the injection pressure is 1 to 5 kg / ㎠, the injection angle is installed near or perpendicular to the top of the super medium cutting surface. According to this specification, the thickness of the sandblasted super medium 6 is usually about 1/2 of the thickness of the super medium, for example, about 0.05 mm, which is about the thickness remaining after peeling off the adhesive tape.

Although the above-described nozzle 14 is provided only on the cut surface of the super medium, when the thickness of the raw material 10 of the super medium is constant, the taper described above is provided by installing the nozzle 14 at the edge of the raw material 10 of the super medium by sand blasting treatment. True grass medium can be prepared.

On the other hand, although the nozzle 14 shown in FIG. 3 is provided in both cutting surfaces, it will be apparent that the nozzle 14 can be provided in each cutting surface.

Next, when the projected object remains on the sand blasted super medium, compressed air is sprayed to remove the remaining projected object. This air blowing process is performed by installing the compressed air jetting nozzle 16 in the sandblasted portion in the same manner as the nozzle 14 described above. In addition, when the residual projected object is distributed on the entire upper surface of the super medium, the residual projected object can be removed by providing a plurality of nozzles 16. Meanwhile, a vacuum pump (not shown) may be installed and used instead of the nozzle 16 so that the residual projectile can be reused.

After compressed air is injected, it is cut by a predetermined length by the cutting machine 18, and finally it is wound up by the roll-shaped rod 20. Thus, the above described medium medium 30 is completed.

Example 2

Instead of cutting the edges of the super medium 30 of the above-described embodiment 1, a super medium simply laminated with webs of different widths may be used, which is illustrated in FIG.

7 is an enlarged longitudinal sectional view showing the super badge according to the second embodiment. As shown in FIG. 7, the super medium 40 of the present embodiment is formed by laminating a first web 41 and a second web 43 wider than the first web 41.

Hereinafter, the apparatus for manufacturing the super medium of Example 2 described above will be described.

The apparatus for producing super medium is largely composed of a blanket 90, cylinder molds 70a and 70b, compression rollers 80a and 80b, and pulp tanks 60a and 60b.

The blanket 90 rotates in the form of a conveyor by a plurality of rollers and conveys the super medium 40 produced by the cylinder molds 70a and 70b described below to another blanket (not shown) in which a heater roll (not shown) is installed. It plays a role.

The cylinder molds 70a and 70b are installed in the pulp tanks 60a and 60b and are composed of a first cylinder mold 70a and a second cylinder mold 70b. Each of the first cylinder mold 70a and the second cylinder mold 70b is formed of meshes 73a and 73b formed on the outer circumferential surfaces of the cylinder bodies 71a and 71b and the cylinder bodies 71a and 71b. Cylinder body (71a, 71b) is driven to rotate, the net body (73a, 73b) is made of a net shape so that the pulp 61 is buried, it is preferable that the mesh is formed on the outer peripheral surface of the cylinder body (71a, 71b).

In addition, the length of the network 73a is preferably formed to be shorter than the length of the network 73b, because if the length of the network 73a is longer than the length of the network 73b is generated in the network 73a This is because the edge of the first web 41 may be damaged when it is laminated with the second web in the mesh 73b.

From this configuration, the small first web 41 is produced by the mesh 73a of the first cylinder mold 70a, and the large second web 43 is formed of the second cylinder mold 70b. It is generated by the mesh 73b, and is laminated with the first web 41 in the process of generating the second web 43.

In this way, if a plurality of meshes having different lengths are installed along the longitudinal direction of the cylinder body, it is possible to mass produce a wide variety of super mediums.If the lengths of the network bodies are the same, the outer peripheral surfaces of the nets are divided by rubber, etc. Can be generated.

Compression rollers 80a and 80b apply pressure to the cylinder molds 70a and 70b to drain the pulp 61 and ensure the transfer to the blanket 90, so that the cylinder molds 70a and 70b are applied to each of the cylinder molds 70a and 70b. The first compression roller 80a and the second compression roller 80b are formed to correspond to each other. Therefore, the blanket 90 passes through the super medium 40 generated while sequentially passing between the first compression roller 80a and the first cylinder mold 70a and the second compression roller 80b and the second cylinder mold 70b. To carry.

The pulp tanks 60a and 60b store the pulp 61 supplied from the mixer 50 and provide the pulp 61 to the cylinder molds 70a and 70b, wherein the pulp tanks 60a and 60b have a first cylinder. It is preferable to divide the first pulp tank 60a in which the mold 70a is installed and the second pulp tank 60b in which the second cylinder mold 60b is installed, because the cylinder molds 70a and 70b are It should be substantially impregnated in the pulp 61, because when the vibration of the pulp is generated by the rotation of each other and the height of the water surface is changed, the pulp cannot be smoothly transferred to the blanket.

As described above, the super medium production apparatus of this embodiment can manufacture the super medium 40 of the second embodiment simply by changing the lengths of the cylinder molds 70a and 70b.

Hereinafter, a description will be given of a method for manufacturing a super medium of the second embodiment, the same reference numerals are used for the same parts as the above-described apparatus, and a detailed description thereof will be omitted.

The first web 41 is formed in the blanket 90 running between the mesh 73a of the first cylinder mold 70a and the first compression roller 80a passing through the first pulp tank 60a. That is, the first compression roller 80a for bubbling the pulp 61 impregnated into the mesh 73a of the first cylinder mold 70a by rotation and applying pressure to the first cylinder mold 70a. The first web 41 is compressed to the blanket 90 while being drained.

The blanket 90, from which the first web 41 is formed, passes through the second pulp tank 60b and is longer than the length of the mesh 73a of the first cylinder mold 70a. When passing between the 73b and the second compression roller 80b, the second web 43 wider than the width of the first web 41 is laminated with the first web 41. At this time, the second compression roller 80b serves as the first compression roller 80a described above.

The lamination of the first web 41 and the second web 43 thus generated rotates along the blanket 90, and then moves the lamination to a blanket (not shown) in which a heater roller (not shown) is installed and moves the laminated paper. Is attached to the heater roller while passing through the heater roller while being separated from the heater roller by a knife (not shown) installed on the heater roller, the super medium 40 is completed.

Gypsum board seam super medium according to the present invention and a method and apparatus for manufacturing the same can be carried out in various modifications within the scope allowed by the spirit of the present invention is not limited to the above-described embodiment. For example, first, the super medium cut without the sand blasting process and the compressed air injection treatment may be wound, and then the sand blasting treatment and the compressed air injection treatment may be performed according to the above-described process.

According to the gypsum board seam super medium according to the present invention as described above and a method and apparatus for manufacturing the same, the following effects are obtained.

First, by using a sandblasted gypsum board seam super medium, the work of reducing the thickness of both edges after the initial fold application can be omitted, thereby improving workability and economic efficiency.

Second, a tapered gypsum board seam super medium may be manufactured by a simple process of installing a sandblasting nozzle on the cutting surface of the super medium.

Third, the work by the sand blasting machine can form a super medium of uniform thickness than the work of smoothing the edges of the edge of the super medium by manual work, so that the adhered state of the paper medium can be better.

Fourth, both edges of the super medium may be formed by fine ruggedness by sand blasting, so that the grass penetrates well and firmly adheres to the gypsum board base surface.

Fifth, by using two sheets of super-deposited paper of different widths, it is possible to prevent the phenomenon of crushing due to the resistance to surface tension generated when the water is dried by watering.

Sixth, it is possible to simply manufacture and produce super medium of different widths by using meshes of different lengths.
