Flame retardant board, also known as flame retardant board, flame retardant plywood, flame retardant plywood, etc., is based on plywood, which has good moisture absorption and breathability of solid wood, and is easy for flame retardant to be evenly distributed in wood materials, which overcomes the shortcoming that ordinary plywood is easy to burn, and can play an effective flame retardant role. Similar to plywood production technology, it is only a number of flame retardant treatment processes.
Working principle of flame retardant board
1. Flame retardant of base material
Environmental-friendly flame retardant with durable flame retardant effect, good loss resistance, water resistance and moisture resistance is selected. After the board base material is treated under special conditions, the flame retardant is fully combined with wood fiber. During the combustion process, the flame retardant board can effectively dilute combustible gas, isolate air and fire source, change the wood cracking process when it is not burned, and control the burning trend and progress of the floor.
2, the surface and the bottom layer are flame retardant
The surface adopts patented technology, and some inorganic toughened materials are added to the surface layer, so that the impact resistance and wear resistance of the floor can be improved, and at the same time, the floor has different general flame retardant effects; In addition, a fireproof board is added to the bottom floor, which can not only be waterproof and moisture-proof, but also be fireproof and flame-retardant.
What are the advantages and disadvantages of the flame retardant board?
Advantages of the flame retardant board
1. Firstly, the flame retardant board can prevent the fire from spreading and win valuable time for escaping from the fire site. The flame retardant board does not mean that it will not burn, but only prevents the fire from spreading rapidly.
2. The flame retardant board is processed on the basis of plywood, which is light in weight, easy to process, convenient to construct and reduces the cost.
3. The flame retardant board has good structural strength and strong bending resistance.
disadvantages of flame-retardant board
1. The flame-retardant board will produce toxic gas during combustion. However, some big brands of flame retardant boards use advanced flame retardants to greatly reduce the generation of toxic gases in fires.
2. After flame retardant treatment, the bonding strength of the flame retardant board will be affected to some extent.
