Description

Manufacturing method of shower board

The invention relates to an air-conditioning water washing device, in particular to a method for manufacturing a shower board of an air-conditioning water washing device.

Press, in many industries such as the clean room of the semiconductor industry (clean room) workshop or environment, most of the outside air conditioning unit (Make-up Air Unit, MAU) will be used for air conditioning and treatment, such as filtering Various gas pollutants (Airborne Molecular Contamination, AMC) generated in the process, wherein the outside air conditioning box is provided with a washing device including a shower board, so that the above gas pollutants pass through the shower board It can be dissolved in the water on the shower board and taken away by the water, so that the outside air conditioning box can achieve the effect of purifying the air.

Existing shower plates are usually formed by stacking a plurality of ceramic plates, wherein the surface of each ceramic plate may have a specific shape, such as a wave shape, and after the ceramic plates are stacked, the overall shower plate may have holes or gaps Or a honeycomb-like structure, which can increase the contact area between the shower board and the air. However, the existing shower board uses ceramic materials, in addition to the higher cost, the manufacturing process involves a sintering molding process, resulting in a longer processing time It has reduced production efficiency and increased manufacturing costs. Therefore, how to improve the above problems is the technical difficulty for the creator of this case.

In view of the above-mentioned problems with conventional shower boards and the manufacturing method thereof, the purpose of the present invention is to develop a method for manufacturing shower boards that can increase production efficiency and reduce manufacturing costs.

To achieve the above object, the present invention provides a method for manufacturing a shower board, including: an impregnation step, which is to process a raw material plate composed of chemical fiber non-woven fabric by impregnation with a thermoplastic resin to become a pre-formed plate; a forming In the step, the pre-formed sheet is processed into a water-sprayed sheet by a vacuum suction process, a compression forming process or a roll forming process.

Among them, the raw material plate is flat.

The chemical fiber of the chemical fiber nonwoven fabric is polyethylene (PE), polypropylene (PP), nylon (Nylon), polyethylene terephthalate (PET), or acetate fiber.

Wherein, the thermoplastic resin is polyacrylate (PMMA), ethylene vinyl acetate copolymer (EVA), polyurethane (PU) or moisture-curing reactive polyurethane (PUR).

Among them, a plurality of water-spraying plates are further stacked to form a finished water-spraying plate.

In this way, the present invention can make a raw material plate made of chemical fiber non-woven fabric into a shower board, eliminating the time-consuming, energy-consuming and high-cost sintering and other steps in the process of the conventional ceramic shower board, and further making the invention Can achieve the effect of improving production efficiency and reducing manufacturing costs.

The first figure is a schematic flowchart of the steps of an embodiment of the present invention.

The second figure is a block diagram of a specific operation flow of an embodiment of the present invention.

Referring to the first and second figures, the present invention provides a method for manufacturing a shower board. The steps include: an impregnation step S1, which is a raw material composed of chemical non-woven fabrics The board is impregnated with thermoplastic resin and becomes a pre-formed board.

Wherein, the raw material plate is in the form of a flat plate, and the chemical fibers of the chemical fiber non-woven fabric may specifically be polyethylene (Polyethylene, PE), polypropylene (Polypropylene, PP), nylon (Nylon), polyethylene terephthalate ( polyethylene terephthalate (PET) or acetate fiber, etc., but in fact it is not limited to this.

In a preferred embodiment of the present invention, the thermoplastic resin used for impregnation can be polymethyl methacrylate (PMMA) and ethylene-vinyl acetate (EVA) ), polyurethane (PU) or moisture-curing reactive polyurethane (PUR), etc., but in fact the same is not limited to those listed above. In addition, in general, the specific impregnation treatment process is usually It may include some or all of the operation steps of multiple stages of impregnating resin, cleaning, heating and curing, drying and cooling, but the specific operation process and detailed process parameters of each stage of the impregnation treatment process involved in the present invention are in the art. The general knowledge of the case is not the point of the invention of this case, so I will not elaborate here. The raw material sheet becomes the pre-forming sheet after being treated with impregnating resin. It is worth mentioning that by impregnation treatment, the pre-forming sheet can It has better acid and alkali resistance to increase its service life, so it can be more suitable for the application of shower boards.

In a molding step S2, the pre-molded sheet is processed into a water-sprayed sheet by a vacuum absorbing process, a compression molding process or a roll-forming process, thus completing the manufacturing process of the water-sprayed sheet of the present invention.

Among them, the vacuum blister process is to use the vacuum suction generated by the vacuum pump to heat and soften the pre-formed sheet through the mold to form the desired shape; the compression molding process is to put the pre-formed sheet into the After reaching the mold temperature in the lower mold (at this time, the upper mold also reaches the operating temperature), and then the upper and lower molds are clamped and pressurized, the pre-formed sheet can be processed into a watered sheet with the desired shape; the rolling The forming process is to heat the plate before forming, through a pair of rollers with opposite rotation directions, and use its mutual rotation to roll (to reduce the thickness of the plate before forming and lengthen the length) to change the cross section of the plate before forming The shape becomes the water-spraying plate; here, the specific shape of the water-spraying plate can be adjusted and changed according to the design requirements through the shape of the mold, the present invention is not limited to this, and the vacuum absorbing process or The detailed operation procedures and process parameters of the hardware and software equipment involved in the steps of the compression molding process or the roll forming process are also common knowledge that is well-known to those skilled in the art, and will not be repeated here. In addition, it can be mentioned that After preparing each piece of water-spraying sheet, as long as a plurality of water-spraying sheets are further stacked, the final product of the water-spraying sheet can be obtained.

Through the steps of impregnation and specific molding process, the present invention can make a raw material plate composed of chemical fiber non-woven fabric into a shower board, eliminating the time-consuming, energy-consuming and high cost of the conventional ceramic shower board process Processes such as sintering, in turn, enable the present invention to achieve the effects of improving production efficiency and reducing manufacturing costs.
