char formation of wood was markedly accelerated by frw, which indicated that catalytic charring effect of frw on wood is the primary side in its fire-retardation mechanism.
frw阻燃处理能显着提高木材燃烧时的成炭率,说明催化成炭是frw阻燃机理的主要方面。
the fire endurance and char formation rate of app/per/mel coatings and eg modified coatings were studied by heat insulation and thermo-gravimetric analysis(tga).
