Description

Environmentally friendly film and substrate forming method

The present invention relates to a method of forming a film and a substrate.

According to the conventional method for manufacturing a film and a substrate, it is necessary to divide into two factories to separately manufacture a substrate and a film, which usually guides a substrate through a dipping tank and through the dipping. Impregnation of the material in the tank, the substrate is introduced into a water tank to gelatinize and solidify the surface thereof, and then dried by an electric heating drying device to form a substrate, and the mask is further manufactured, and then the base is made by an adhesive. The material and the mask are adhered to each other, that is, the finished product of the synthetic skin is completed.

However, in the manufacturing process of the conventional synthetic skin, a large amount of solvent is used in the manufacture of the substrate or the mask, which causes serious environmental pollution to the environment, or poisoning through absorption by the human body, and is used in the laminating step. The adhesive is also a solvent, and the above-mentioned environmental pollution is also caused, and the substrate and the mask must be divided into two factories to be separately manufactured, and then the adhesive is used to bond the substrate and the mask to each other, regardless of the substrate. Or the mask is manufactured in multiple processes, the use of the factory is idle, and the manufacture of the substrate or the mask uses electrothermal drying equipment, which consumes a considerable amount of electricity, labor and other production costs, and the edge of the base fabric Because of the small area, it is not reusable for the processing and production process. It is discarded and disposed of as waste. The waste is disposed of in a landfill or burned in an incinerator facility, except for the environment. In addition to pollution, it will also cause health problems in local organisms. Therefore, how to develop an environmentally friendly membrane that does not use ovens, solvents, and has energy-saving, carbon-reducing and environmental benefits.
