Magnesium hydroxide classification and presentation

Magnesium when heated (340-490 degrees) decomposes to absorb the combustion flame retardant surface heat; while releasing  heat stabilizer for panel large amounts of water dilute combustible surface oxygen, decomposition of the active magnesium oxide attached to combustible surfaces to prevent further the burning proceed. Magnesium hydroxide flame retardant in the whole process  not only does not produce any harmful substances, and its decomposition products in a fire, while also able to absorb a lot of rubber, plastics and other polymer produced by combustion of harmful gases and smoke, constantly absorbing active magnesium oxide unburned melt residues butyl stearate  from the combustion stop soon while eliminating smoke, preventing droplet, is an emerging environmentally friendly inorganic flame retardants.
Flame retardants can be classified according to the chemical composition of organic and inorganic flame retardants two categories. Organic phosphorus flame retardants are divided into two series, and halogen. Since the existence of organic flame retardants toxic decomposition products, smoke and other shortcomings, are gradually being  titanium dioxide replaced by inorganic flame retardants.
The main varieties are inorganic flame retardant aluminum hydroxide, magnesium hydroxide, red phosphorus, antimony oxide, tin oxide, molybdenum oxide, ammonium molybdate, zinc borate, in which aluminum hydroxide and magnesium hydroxide due to the endothermic decomposition of large and produce H2O can play the role of the absence of air, its decomposition temperature oxide material is therefore two kinds of flame retardants can not only play the role, but also can play a role in filling, it has no corrosive halogen gas and harmful gases, non-volatile, long lasting, non-toxic, smokeless, no drip characteristics.
