High-end flame retardant market, unlimited development of magnesium hydroxide

2020-07-10 14:22:13

Magnesium hydroxide is a new type of filled flame retardant, which releases bound water during thermal decomposition absorbs a large amount of latent heat, thereby reducing the surface temperature of the filled synthetic material in the flame inhibiting polymer decomposition the effect of cooling the generated combustible gas. Talc manufacturer

For a long time, magnesium hydroxide flame retardants have been high-end products in my country, which are basically blank. my country imports about 30,000 tons each year, most of which are used by foreign-funded enterprises in China, mainly for high-end materials, such as wires cables for nuclear power plants, insulation materials for high-speed rail, communication equipment.


Indispensable material

Magnesium oxide produced by thermal decomposition of magnesium hydroxide is an ideal refractory material. In addition to helping optimize the fire resistance of synthetic materials, the water vapor released by decomposition also has a smoke suppression effect. Therefore, in the rubber industry, magnesium hydroxide is a recognized high-quality flame retardant with three functions: smoke suppression, filling, flame retardancy. At present, in the field of communication cables, the consumption of inorganic flame retardants in foreign countries such as Japan, the European Union, the United States exceeds 64%, while China only accounts for 8%.

As an inorganic flame retardant, magnesium hydroxide only has the flame retardant effect, but also has the function of suppressing smoke. In the fire, more than 80% of the victims were burned to death, but asphyxiated due to heavy smoke. The addition of magnesium hydroxide flame retardant can greatly reduce the smoke density during combustion reduce the risk factor of people being choked to death. Secondly, the polymer material will have a thermal insulation effect after adding magnesium hydroxide. Once burned, magnesium hydroxide will form a film of magnesium oxide. This layer of magnesium oxide film is resistant to high temperatures, can prevent further combustion, isolate the air other combustibles, improve people's chances of survival in the event of a fire.

Magnesium hydroxide is added to the wall materials of foreign high-end villas, the insulation effect is very ideal. In addition, most airports large supermarkets also use magnesium hydroxide flame-retardant materials on the roofs, which are insulated in summer warm in winter. Although the amount of magnesium hydroxide flame retardant abroad is very large, the amount of magnesium hydroxide flame retardant used in China is much.
