The main raw materials of magnesite fireproof board are magnesia and magnesium chloride, as well as industrial and agricultural wastes such as fly ash and crop straw. At the same time, various compound additives such as water resistance, toughening, moisture proof and early strength are added, and the latest research is adopted. The results and patented technology not only completely solve the problem of poor halogenation and poor water resistance, but also have the characteristics that high-strength, anti-corrosion, insect-free, fire-proof and other woods do not meet the needs of people at different levels of life and production. With the introduction of the government's policy of promoting energy-saving and environmentally-friendly new materials, various new types of building materials have appeared on the market, which can be described as numerous. Compared with other sheet projects, the sheet project has its own advantages and long-term development potential.

characteristic
After thermosetting, the melamine resin has high surface hardness, wear resistance, high temperature resistance, impact resistance, small pores on the surface, and is not easily contaminated, and has mechanical strength such as solvent resistance, water resistance, chemical resistance and flame resistance. Insulation, arc resistance and aging. The surface of the fireproof board is glossy, and the transparency is very good to restore the color and the pattern has a high simulation. The phenolic resin forms a very high density after thermosetting, and has the characteristics of temperature resistance, water resistance and hardness.
In fact, it is more accurate to say that it is a decorative board, but it is commonly known as a fireproof board in China. The domestic manufacturer base is mainly located in Changzhou, Jiangsu Province, and has a geographical advantage and long-term research on technology. The industry must go, Henglin Town, Jiangsu Wujin, and also has the title of China's laminate flooring capital.
