Description

Fireproof treatment technology of wood

The wood is placed in a high-pressure tank. Firstly, the wood is vacuumized to remove the gas inside the wood. With the help of vacuum, the flame retardant is inhaled, and then the flame retardant is pressed into the wood under pressure. The segmented impregnation method is to impregnate different flame retardants separately, so that the agents before and after treatment react with each other to produce precipitation. The weight of wood impregnated by this method can be increased by more than 20% after drying, and the ceramic, flame retardancy, hardness and dimensional stability of wood after drying are greatly improved.

Advantages

Cedar shingles are the most widely used wood shingles in the world, with natural and beautiful texture, green environmental protection, non-toxic and harmless, widely used in building roofs and side walls.

Many dry climate areas want to have fire-proof tiles, cedar tiles can also be fire-proof.

Wood is a kind of porous and complex natural organic material composed of cellulose, hemicellulose and lignin. It has high hydrocarbon content and is flammable. Wood flame retardant is to improve wood’s anti combustion ability through physical or chemical methods, in order to slow down wood combustion and prevent fire accidents. The requirements of wood flame retardant are to reduce the burning speed of wood, reduce the flame propagation speed and accelerate the carbonization process of burning surface. It will not destroy the physical and mechanical properties of wood.
