Polyphosphoric Acids Flame Retardant
Halogen Free Flame Retardant of APP Base, Water Soluble, for Wood Fireproof Treatment
Methods of wood fire treatment are as follows:
1. The impregnation treatment of fire retardant du is mainly used to prevent or delay the rise of wood temperature during the fire, reduce the speed of flame spread and reduce the speed of flame penetration through the wood.
2. Surface coating treatment, this treatment can be carried out on the construction site, the surface of the wood is coated with fire retardant to separate the wood from the heat source. During construction, the surfaces of cabinets, door leaves, and cabinet door panels are generally fire-treated.
