What is the flame retardant principle of wood flame retardants?
1. Flammable wood when heated, wood flame retardant decomposition of non-flammable gases and non-volatile acidic molten material, with reduced system temperature and oxygen concentration and shielding the role of thermal radiation, reducing the rate of wood pyrolysis;
3. Boric acid and GUP from the role of flame retardant and the way the different, and have a complementary role, which showed a flame retardant synergistic effect.
2 wood flame retardant components of boric acid and GUP acid decomposition products catalyzed wood dehydration, degradation, and wood pyrolysis products of condensation, polymerization, aromatization and other reactions, can change the way of wood pyrolysis and make it conducive to The direction of carbonization, wood flame retardant significantly catalytic role in the charcoal, so that the combustion of wood burning heat greatly reduced, which is the main aspects of wood flame retardant flame retardant mechanism; more wood knowledge and information in the wood sector number.
