Magnesium hydroxide particle size, small wear and tear on the equipment, to extend the service life of processing equipment, while the raw material is easy to obtain, low production costs, can be widely used in polypropylene, polyethylene, polychlorinated ethylene, high impact polyphenylene ethylene and ABS and other fields. At present, more than 20 enterprises in nearly 10 countries produce more than 20 varieties, with a total annual production capacity of about 170,000 tons. Many countries are still building or planning to build a new device of magnesium hydroxide. According to the research of Hebei Messi Biology Co., the total annual capacity of magnesium hydroxide plant to be built in recent years is about 140,000 tons.
Magnesium hydroxide is an additive inorganic flame retardant, compared with similar inorganic flame retardants, has a better smoke suppression effect. As 80% of the fire by smoke asphyxiation and death, so the contemporary flame retardant technology “smoke suppression” than “flame retardant” is more important.
Magnesium hydroxide in the production, use and disposal process are no harmful substances emitted, but also can neutralize the acidic and corrosive gases generated in the combustion process, is an environmentally friendly green flame retardant. The high thermal decomposition temperature of...
