Description

The present invention relates to a dust adsorbing sheet for an air shower device, a dust adsorbing method for an air shower device, and a dust adhering sheet affixing method for an air shower device, and more specifically, can be easily attached to a wall surface of an air shower chamber, By adsorbing dust blown off from a person or object in the sealed space of the shower device, it is possible to prevent the dust that has been blown away from flying again from adhering to the person or object. The present invention relates to a dust adsorption method for an air shower device and a dust adsorption sheet attaching method for an air shower device.

Manufacturing factories for semiconductors, liquid crystals, precision instruments, foods, etc. manufacture products in a clean room in order to prevent dust from adhering to the products. The clean room itself has a function to clean the air inside, but when people or goods (objects) enter and exit, the dust adhering to the surface is newly brought into the clean room. This is one of the factors that reduce cleanliness. Usually, in order to prevent such dust from being brought in from the outside, an air shower is installed at the entrance of the clean room, and people entering the clean room or materials to be carried first enter the air shower device first. The dust attached to the surface is removed by blowing air on the material (object). And after removing the adhering dust, it enters into a clean room (it carries in).

Dust blown up and blown away from people and goods (objects) in the air shower device is usually discharged from the exhaust part of the air shower device, but part of the dust is not discharged. There was a problem that it was lifted and floated, and then reattached to people and objects and brought into the clean room.

On the other hand, as a method for removing dust floating in the working chamber, for example, in a painting chamber in an automobile manufacturing factory, the adhesive surface of the adhesive sheet is exposed to the indoor side of the working chamber and is attached to the wall of the working chamber. A method is known (see, for example, Patent Document 1). According to this method, in a work room having a flat or simple curved wall surface, dust floating in the work room can be adsorbed to the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet.

However, the present invention is limited to the following embodiment. However, it should be understood that design changes, improvements, and the like can be made as appropriate based on ordinary knowledge of those skilled in the art without departing from the spirit of the present invention.

1 (a) to 1 (c) schematically show an embodiment of a dust adsorbing sheet for an air shower device according to the present invention. FIG. 1 (a) is a plan view and FIG. 1 (b) is a plan view. 1A is a cross-sectional view taken along line AA ′, and FIG. 1C is a cross-sectional view taken along line BB ′ of FIG.

A sheet shape in which a cutout portion 3 having a shape corresponding to the opening of the air injection portion is used by being attached to a wall surface of an air shower chamber in which an air injection portion for blowing off dust attached to a person or an object is formed. The base material 2, the adhesive layer 4 containing an adhesive that can adsorb dust and disposed on one surface of the base material 2, and the other surface of the base material 2, And a pasting means 5 for pasting to the head. Furthermore, the dust adsorbing sheet 1 for an air shower device according to the present embodiment includes a sheet-like release sheet 6 disposed so as to cover the adhesive layer 4.

FIG. 2 is a plan view schematically showing a state where the dust adsorbing sheet for an air shower device of the present embodiment is attached to one wall surface of the air shower device, and FIG. 3 is an air shower of the present embodiment. It is the perspective view which partially showed the state when affixing one dust adsorption sheet for apparatuses to one wall surface of an air shower chamber. As shown in FIGS. 2 and 3, when the dust adsorbing sheet 1 for an air shower apparatus according to the present embodiment is attached to the wall surface 11 of the air shower chamber, the base material 2 is attached to the wall surface of the air shower chamber by the attaching means 5. In addition, with the adhesive layer 4 on which the release sheet 6 is disposed facing the sealed space side, the cutout portion 3 is aligned so as to enable air injection corresponding to the opening of the air injection portion. Then, the release sheet 6 is peeled off from the adhesive layer 4 to expose the adhesive layer 4 in the sealed space. And the dust which blown off by the air which passed through the cut-out part 3 from the air injection part 12, and was injected in the space, and flew up in sealed space is the adhesion layer 4 of the dust adsorption sheet 1 for air shower apparatuses. Adsorb with.

Thus, the dust adsorbing sheet for the air shower device of the present embodiment has a cutout portion having a shape corresponding to the opening of the air injection portion of the air shower device, and the cutout portion corresponds to the opening of the air injection portion. In order to be affixed to the wall surface of the air shower chamber in a state of being aligned so as to enable air injection and with the adhesive layer exposed to the sealed space side, it has an air injection part, It can be easily attached to the wall surface of the special structure of jetting air from there without the complicated processing work of the dust adsorbing sheet for the air shower device, making the inner wall surface of the air shower device effective. Floating dust can be adsorbed and removed while being used. Further, it eliminates the need to manually remove the reattached dust using an adhesive roller or the like. In addition, the air shower device injects air from the air injection unit, blows off dust adhering to people, etc., discharges the air to the outside from the floor portion of the air shower chamber, etc. In the case of a mechanism that removes the dust contained in the air and then ejects it again from the air ejecting unit or discharges it to the outside, the dust for the air shower device according to the present embodiment can be used. Since dust is removed by the suction sheet, there is an advantage that the burden of removing dust by the dust removal filter is reduced and the life of the filter is extended.

Here, the wall surface 11 shown in FIG. 2 constitutes the wall surface of the air shower chamber. The air shower chamber is formed in the air shower device and is formed from a sealed space surrounded by the wall surface 11 on all sides, the ceiling and the floor. Then, the air jetted from the air jetting part 12 disposed on the wall surface 11 is blown to a person or an object that has entered the sealed space, and the adhering dust is blown off and removed. And the air and the dust which floated from the air injection part 12 are formed so that an exhaust port may be formed in one wall surface in the wall surface 11, and it may be discharged | emitted from there. The air injection part may not be formed on the wall surface where the exhaust port is formed.In that case, the cutout part is not attached to the wall surface of the dust shower sheet for the air shower device of this embodiment. You may stick the dust adsorption sheet which does not form. As the dust adsorbing sheet that does not form the cutout portion, the dust adsorbing sheet for the air shower device of the present embodiment that does not have the cutout portion can be used.

In the present embodiment, the base material 2 shown in FIG. 1B is formed in a rectangular flexible (flexible) sheet shape, and has a cutout portion having a shape corresponding to the opening of the air injection portion of the air shower device. 1 (see FIG. 1A). The shape of the cutout 3 is circular as shown in FIG. 1 (a), but since this is a shape corresponding to the opening of the air injection part, the opening of the air injection part has many shapes such as an ellipse and a rectangle. Similarly, in the case of a square or the like, it is also preferable to use an oval or a polygon such as a quadrangle. Here, the opening of the air injection part is a hole for blowing out air from the air injection part. When the air injection part protrudes in a nozzle shape, the outer peripheral shape (cross-sectional shape) of the nozzle corresponds. . The shape corresponding to the opening means the same shape as the opening or a slightly larger shape. Moreover, in this Embodiment, although the cutout part 3 is formed in one place with respect to the one base material 2, this is not limited to one place, The dust adsorption sheet for air shower apparatuses Depending on the size of the air shower and the size and arrangement of the air jetting part of the air shower device, the number of the air jetting units can be appropriately two or more.

Moreover, as shown to Fig.1 (a), the base material 2 (refer FIG.1 (b)) is provided with the four cuts 21 which face the center direction of the cutout part 3 in the periphery of the cutout part 3. FIG. . Thereby, for example, even if the air injection part has a shape in which a cylindrical nozzle protrudes and the outer diameter of the nozzle is larger than the diameter of the cutout part 3, the base material 2 opens so that the part of the cut 21 is opened. The nozzle having a large outer diameter can be passed through the cutout portion 3. As a result, the dust suction sheet for an air shower apparatus having one type of size can be made to correspond to nozzle-like air injection units having different outer diameters.

When pasting the base material 2 (see FIG. 1B) on the rectangular wall surface 11 as shown in FIG. 2, it is preferable that the base material 2 is spread as much as possible so that the outer shape of the base material 2 is rectangular or square. However, the present invention is not limited to this. For example, any shape such as a rectangle other than a rectangle, other polygons, a circle, an ellipse, or the like may be used. Moreover, the dust adsorbing sheet for the air shower device of the present embodiment and the dust adsorbing sheet for the air shower having no cut-out portion (the dust adsorbing sheet for the air shower device of the present embodiment having no cut-out portion) May be combined to eliminate the gap.

As a constituent material of the base material 2, it is preferable to use a synthetic resin such as vinyl chloride, polyester, CPP (polypropylene unstretched film), polyethylene, nylon, ethylene vinyl acetate copolymer, and kraft paper, synthetic paper. Etc. are preferably used. By using such a material, it is possible to provide the base material 2 with lapping properties and familiarity, and to prevent curling.

As for the thickness of the base material 2, 50-200 micrometers is preferable. If it is thinner than 50 μm, it may be easily torn, and if it is thicker than 200 μm, the flexibility may be lowered and it may be difficult to stick to the wall surface. The magnitude | size of the base material 2 is not specifically limited, Workability | operativity is good when it affixes on the wall surface of an air shower chamber, and it should just be hard to peel even after affixing. For example, assuming a rectangle, the long side is preferably 20 to 200 cm, and the short side is preferably 20 to 100 cm. The long side and the short side may have the same length (the lengths of the four sides are equal).

The adhesive layer 4 disposed on one surface of the base material 2 shown in FIG. 1 (b) has an acrylic, natural rubber, styrene butadiene rubber, styrene isoprene styrene block polymer, silicone as an adhesive. It is preferable to use a rubber-based pressure-sensitive adhesive because it has high adhesive strength and a long adhesive duration. In particular, an acrylic pressure-sensitive adhesive is preferable because it has a high initial adhesive strength and can effectively fix dust and fiber debris having a small mass and a small contact area with the pressure-sensitive adhesive layer 4.

The adhesive strength of the adhesive contained in the adhesive layer 4 is preferably 200 to 700 g (measured in accordance with JISZ0237). In addition, P.A. The tack is preferably 200 to 700 g (measured according to JISZ0237 reference column), the peel force is preferably 5 to 20 g (measured according to JISZ0237), and the ball tack is 5 to 20 g (JISZ0237). Preferably measured in accordance with

As for the thickness of the adhesion layer 4, 50-150 micrometers is preferable. If it is thinner than 50 μm, the adhesiveness may be lowered, and if it is thicker than 150 μm, the adhesive may protrude from the peripheral portion of the dust adsorbing sheet for the air shower device. The adhesive layer 4 is preferably disposed on almost the entire surface of the substrate 2.

The affixing means 5 shown in FIGS. 1 (a) and 1 (b) is obtained by affixing a belt-like double-sided adhesive tape along one side of the substrate 2 and a side (parallel) opposite to the side. . The double-sided adhesive tape is composed of a sheet-like base material and an adhesive layer having an adhesive disposed on both sides thereof. It does not specifically limit as a double-sided adhesive tape, What can paste commercially available papers, such as a poster, on a wall can be used. The affixing means 5 is preferably arranged along the two opposing sides of the base material 2 as described above so that the dust adsorbing sheet 1 for the air shower device is not peeled off by air. It is more preferable that the adhesive strength is increased. Further, the affixing means 5 can be appropriately disposed at other locations.

The sticking means is not limited to the one in which the double-sided adhesive tape is disposed on the base material, and the dust adsorbing sheet for the air shower device can be stably attached to the wall surface without being peeled off by air. I just need it. For example, a hook-and-loop fastener can be used. A hook-and-loop fastener usually has a strip-shaped tape having a large number of hook-shaped projections on the surface and a strip-shaped tape having a large number of loops on the surface, and the surface having the respective projections and the surface having the loops are overlapped. The whole surface is stuck by the hook of the protrusion and the loop. The hook-and-loop fastener is not limited to this, and one having both a protrusion and a loop on one surface can be used. Use of a hook-and-loop fastener is preferable in terms of improving workability when replacing the dust adsorbing sheet for an air shower device. When using a hook-and-loop fastener, for example, a strip-shaped tape (adsorption sheet side tape) having a large number of hook-shaped protrusions on the surface is disposed along two opposing sides of the substrate, and an air shower on the wall surface of the air shower chamber Use a hook-and-loop fastener for the dust adsorbing sheet for air shower equipment by disposing a strip of tape with a number of loops on the surface at a position corresponding to the adsorbing sheet side tape at the position where the dust adsorbing sheet for equipment is attached. Can be attached to the wall. The hook-and-loop fastener is not particularly limited, and a commercially available one can be used. The thickness of the hook-and-loop fastener (the combined thickness when two tapes are attached) is preferably 0.3 to 2 mm, more preferably 0.5 to 1.5 mm, and 0.7 to 1. 1 mm is particularly preferable. When the thickness is less than 0.5 mm, the force for attaching the dust adsorbing sheet for the air shower device to the wall surface is weakened and may be easily peeled off. If it is thicker than 2 mm, the dust adsorbing sheet for the air shower device may be easily peeled off from the wall surface by air.

The release sheet 6 shown in FIG. 1A to FIG. 1C is disposed on the surface of the adhesive layer 4 to prevent the adhesive layer 4 from being deteriorated in adhesiveness. The shape of the release sheet 6 is preferably substantially the same as that of the substrate 2 or slightly larger. Moreover, you may cut out the part corresponding to the cutout part 3 formed in the base material 2, and you may affix on the surface of the adhesion layer 4 in the state which is not cut out.

As the release sheet 6, kraft paper, high-quality paper or the like laminated with a polyolefin-based or other synthetic resin film, or a film such as polyester, OPP (polypropylene stretched film), or CPP (polypropylene unstretched film) can be used. As the release agent, a fluorine-based, olefin-based or wax-based release agent can be used. In general, silicon-based release agents may be used, but silicon may cause corrosion of electronic components. For example, when used in an air shower installed in a clean room of an electronic component factory. It is preferable not to use a silicon release agent.

Next, the manufacturing method of the dust adsorption sheet for air shower apparatuses of this Embodiment is demonstrated. The base material constituting the dust adsorbing sheet for an air shower device according to the present embodiment can be produced by extrusion forming a general flexible sheet using a predetermined raw material. Next, an adhesive layer material containing a predetermined adhesive is applied to one surface of the substrate to form an adhesive layer. Next, a film-like release sheet produced by extrusion or the like is attached to the surface of the adhesive layer. Next, the release sheet on one side of the double-sided pressure-sensitive adhesive tape is peeled off and attached along two opposing sides of the other surface of the substrate. Next, the dust adsorbing sheet for an air shower device can be obtained by cutting out a portion corresponding to the cutout portion by die cutting or a cutter.

It is preferable that the dust adsorbing sheet for an air shower device of the present embodiment is stuck so that there is almost no gap on the entire wall surface of the air shower device. If there is a gap, the number of surfaces that adsorb dust is reduced, and the dust removal efficiency may be reduced. Therefore, the dust adsorbing sheet for the air shower device of the present embodiment and the dust adsorbing sheet for the air shower having no cut-out portion (the dust adsorbing sheet for the air shower device of the present embodiment has no cut-out portion) May be combined to eliminate the gap.

Next, an embodiment of the dust adsorption method for an air shower device of the present invention will be described.

In the state where the adhesive layer 4 is exposed to the sealed space side on the wall surface 11 of the air shower chamber shown, the cutout portion 3 corresponds to the opening 13 of the air injection portion 12 so that air can be injected. In an aligned state, the adhesive layer 4 is applied to the dust that has been pasted and blown off by the air jetted into the space after passing through the cutout portion 3 from the air jetting portion 12 and flew up into the sealed space. It is adsorbed with. Here, as a structure of an air shower apparatus, it can be made to be the same as that of the air shower apparatus demonstrated in the dust adsorption sheet for air shower apparatuses of the said invention.

Affixed to the wall of the chamber with the adhesive layer exposed to the sealed space and with the cut-out part aligned with the opening of the air injection part to enable air injection. Therefore, it can be easily attached to the wall surface of a special structure that has an air injection part and injects air from there, without carrying out complicated processing work of the dust adsorption sheet for the air shower device. Thus, floating dust can be adsorbed and removed while effectively using the inner wall surface of the air shower device. Further, it eliminates the need to manually remove the reattached dust using an adhesive roller or the like.

In the dust showering method for an air shower device according to the present embodiment, since the dust suction sheet for an air shower device according to the present invention is used, processing is performed by cutting the suction sheet according to the structure of the wall surface of the air shower device.

Further, by using a hook-and-loop fastener as the attaching means, it is possible to more efficiently perform the attaching and peeling operations.

In the dust adsorbing method for an air shower apparatus according to the present embodiment, the air adsorbing layer is attached to the wall surface of the air shower chamber while the adhesive layer is exposed to the sealed space side. Dust that has been swollen by the air jetted from the air circulates violently in the sealed space together with the air, so that a lot of dust collides with the wall surface of the air shower room, sticking to the adhesive layer exposed on the wall surface, and removing it Is done. As a result, the dust can be absorbed and removed on the entire wall surface to which the dust adsorbing sheet for the air shower device is attached, so that the dust can be efficiently removed, and the dust is reapplied to people and objects in the air shower device. It can prevent adhesion.

In the dust adsorbing method for an air shower device according to the present embodiment, when the dust adsorbing sheet for the air shower device is attached to the wall surface of the air shower chamber, the dust adsorbing sheet for the air shower device is prevented from loosening as much as possible. It is preferable to reduce the gap between the dust adsorbing sheet and the wall surface. When the gap becomes large, the dust adsorbing sheet for the air shower device may be peeled off or torn by the jetted air.

In the dust adsorbing method for an air shower device according to the present embodiment, when a plurality of dust adsorbing sheets for the air shower device are attached to the wall surface of the air shower chamber, the gap between the dust adsorbing sheets for the air shower device is eliminated as much as possible, It is preferable to spread on the floor. If there is a gap, the number of surfaces that adsorb dust is reduced, and the dust removal efficiency may be reduced. Therefore, the dust adsorbing sheet for an air shower device of the present invention is combined with the dust adsorbing sheet for an air shower having no cut-out portion (the dust adsorbing sheet for the air shower device of the present invention having no cut-out portion). The gap may be eliminated.

The dust adhering sheet affixing method for an air shower device according to the present embodiment is obtained by attaching the base material 2 of the air adsorbing device dust adsorbing sheet 1 shown in FIGS. In the state where the adhesive layer 4 is exposed to the sealed space side on the wall surface 11 of the air shower chamber shown in FIG. 2, the cutout portion 3 can be injected with air corresponding to the opening 13 of the air injection portion 12. It is pasted in a state where it is aligned. Here, as a structure of an air shower apparatus, it can be made to be the same as that of the air shower apparatus demonstrated in the dust adsorption sheet for air shower apparatuses of the said invention.

Thus, according to the dust adsorbing sheet affixing method for an air shower device of the present embodiment, when the dust adsorbing sheet for an air shower device of the present invention is affixed to the air shower chamber, the base material is affixed. In a state where the adhesive layer is exposed to the sealed space side on the wall surface of the air shower chamber and the cutout portion is aligned so as to enable air injection corresponding to the opening of the air injection portion Therefore, it is easy to attach to the wall surface of the special structure that has an air injection part and injects air from there without carrying out complicated processing work of the dust adsorbing sheet for the air shower device. It is possible to absorb and remove floating dust while effectively using the inner wall surface of the air shower device. Further, it eliminates the need to manually remove the reattached dust using an adhesive roller or the like.

In the dust shower sheet attaching method for an air shower device according to the present embodiment, since the dust suction sheet for an air shower device of the present invention is used, the suction sheet is cut according to the structure of the wall surface of the air shower device. Therefore, it is not necessary to perform an operation of processing and pasting, so that it can be pasted with a very simple operation.
