In fact, for the current market situation of building materials, Xiaobian did not do more to understand, but at least Xiaobian knows that more plastic plates are used now, plastic plate production is more special, and widely used, but many friends do not understand the knowledge of plastic plates. So what are the raw materials of plastic sheet, and what is the processing technology of plastic sheet? Below, we will follow Xiaobian to look at the knowledge of plastic sheet.
(1) Resin plastic veneer decorative board commonly used resins are melamine resin, phenolic resin, urea formaldehyde resin, unsaturated polyester resin, acrylic phthalate resin, guano amine resin and so on. At present, melamine resin and phenolic resin are mainly used in China.
(2) Surface paper and bottom paper Surface paper is placed on the top of the decorative board, impregnated resin and hot pressing, with a high degree of transparency and hardness, play a role in protecting the surface of the decorative board. This paper is thin, white, clean, and has high absorption properties.
(3) Decorative paper Decorative paper is placed under the surface paper in the product structure, which mainly provides the decorative effect of the pattern and prevents the covering effect of the bottom glue from seeping. Decorative paper requires smooth surface, good absorption and adaptability, uniform tone of the background color, color requirements of bright color.
(4) The covering paper is sandwiched between the decorative paper and the bottom paper to cover the dark bottom layer and prevent the phenolic resin glue from penetrating the decorative paper. If the decorative paper has enough cover, do not cover the paper. Covering paper and decorative paper are also titanium white paper.
(5) The release paper base paper is the same as the bottom paper, and the impregnated oleic acid glue is configured under the bottom paper to prevent the phenolic resin glue from sticking to the aluminum plate during the hot pressing process. Polypropylene film can be used to cover the aluminum plate to eliminate the release paper.
The production process of plastic sheet is to impregnate the surface paper, decorative paper, covering paper and bottom paper with resin respectively, after drying, the billet is formed, and after hot pressing it is a plastic sheet.
Plastic sheet processing technology is relatively simple, the operation is also convenient. It is mainly for the processing business that the precision of plastic sheet scuttling is not high, but relative to CNC engraving, the precision is not so high, one is manual control, and one is CNC programming. The cutting accuracy of plastic sheet is generally controlled at about 0.5mm, and the CNC engraving accuracy is controlled within 0.15mm.
What are the types of plastic sheet raw materials, and the relevant content of plastic sheet processing technology, Xiaobian will explain so much for you. If you want to further understand the types of plastic sheet raw materials and processing technology, Xiaobian suggests that you can directly go to the plastic sheet market to take a look, so that we can directly contact the plastic sheet, so that it is more conducive to our understanding and mastery of the knowledge of plastic sheet.
