1. First of all, the flame retardant board can prevent the fire from spreading and win valuable time to escape 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 in construction and low in 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 when burning. The advanced flame retardant is used in the fire protection board of Millennium Ship, which greatly reduces the generation of toxic gases in the fire. ?
2. The flame retardant board after flame retardant treatment will have a certain impact on the bonding strength of the board.
Working principle of flame retardant board:
1. flame retardant for base material: choose environmentally friendly flame retardant with durable flame retardant effect, good loss resistance, water resistance and moisture resistance. After the substrate of the board is treated under special conditions, the flame retardant is fully combined with the wood fiber. Flame retardant board can effectively dilute combustible gas, isolate air and fire source, change the cracking process of wood when it is not burning, and control the burning trend and progress of the floor, thus achieving the purpose of flame retardant.
2. Flame retardancy of the surface layer and the bottom layer: the surface layer adopts patented technology, and some inorganic toughening materials are added to the surface layer, which can increase the impact resistance and wear resistance of the floor, and the floor has different general flame retardant effects; In addition, the fire-proof board is added to the bottom floor, which is waterproof and moisture-proof, and can be fire-proof and flame-retardant.
