to the surface of the moisture. With the advent of the opportunity to use other materials on the market, products of a completely new generation and new opportunities began to appear. So, it would seem, a plate from chipboard completely inappropriate for these purposes can compete with the life of a tree. This is achieved, first of all, by protecting from moisture getting into the plate. For this, several types of coating are used. The most commonly used option is lamination. Distinguish standard thermal pressing and post -forming. The last method is preferable. Laminated by the method of post -forming coating is several layers of paper impregnated with formaldehyde resins, compressed with a surface at a temperature of about 180 ° C. It is distinguished from standard pressing that when heated, a layer of protective coating is softened and tightly fixed in the given form of the base. This allows the surfaces from chipboard to acquire qualities comparable in hardness with wood of valuable species and calmly withstand quite high temperatures. For example, a pan or a boiling kettle will not hurt the coating at all. Production technology allows you to perform a thermal pressing along the rounded edge, which significantly improves the appearance and eliminates the need to protect the facial end edge. However, all other ends need sealing. The edge adjacent to the window block is most often treated with a sealant, and the side ends with special plugs or bromatic materials. The choice of coating by color and texture is huge and allows you to choose the necessary desired option. Laminated wood and natural stone coatings are most popular and in demand. The disadvantages include insufficient resistance of coatings on a melamine basis to some aggressive substances and the ability to scratch the front surface. High -quality HPL high pressure plastics are deprived of these shortcomings.
