Flame Retardancy principle of Aluminum Hydroxide
Aluminum hydroxide flame retardant containing water can produce hydroxyl hydroxide, aluminum hydroxide decomposition temperature of 200t, it is in the range from 245 - 300t has basically completed the dehydration reaction, the release of crystal water, absorption of latent heat, Reduce the temperature, that is, fire-retardant technology in the "cooling technology", resulting in a large number of water vapor can dilute flammable gases, combined with 34.6mol of water per mole of aluminum hydroxide, heat to absorb heat 1.97kj, also played a cooling effect.
After the dehydration of aluminum hydroxide in the combustible surface of the fire properties of the formationof a good uniform distribution of metal oxides, and other carbonized material together with the formation of a dense flame retardant barrier, cut off the air, reduce the burning rate, thereby reducing the rate of decomposition of the mass loss rate , To prevent the spread of flame.
