Magnesium hydroxide and aluminum hydroxide flame retardant disadvantages

Magnesium when heated (340-490 degrees) decompose the surface absorption burning calories play a flame retardant; while releasing large amounts of water dilute combustible surface oxygen, decomposition of the active magnesium oxide attached to combustible surface is further prevents burning for

. 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 incomplete combustion

Burning melting residues from the combustion stop soon while eliminating smoke, preventing droplet, is an emerging environmentally friendly inorganic flame retardants.
Aluminum hydroxide (Aluminium hydroxide), chemical formula Al (OH) 3, of aluminum hydroxide. Is an alkali, but also significant because certain acidic, so can be called aluminate (H3AlO3), but the actual generated by the reaction with alkali aluminate is a partial, it is often

In seeing it as a partial hydrate aluminum acid (HAlO2 · H2O). Use is divided into two kinds of industrial grade and pharmaceutical grade. Very little to do with this flame.
