In the building materials market, there are many names for flame retardant boards, such as flame retardant plywood, flame retardant plywood, flame retardant board, and so on. This type of board is a three-layer or multi-layer plywood made by rotary cutting logs into wood chips, flame retardant treatment of the wood chips, and then bonding with adhesive.
Usually, odd layers of wood chips are used, and the fiber directions of adjacent layers of wood chips are glued perpendicular to each other, which can generally overcome the defects of wood and greatly improve its physical and mechanical properties. At the same time, it also overcomes the disadvantage of ordinary plywood being prone to combustion, effectively improving the flame retardant performance of plywood.
It should also be noted that the decoration of public places has strict fire prevention requirements. In public places such as commercial squares, stations, libraries, exhibition halls, etc., various flame retardant materials need to be used, including flame retardant boards. When a fire occurs indoors, flame-retardant panels can control the spread of the fire, reduce the heat generated by the fire, and thus provide valuable escape time for people.
Flame retardant boards possess five major characteristics: flame retardancy, smoke suppression, corrosion resistance, insect resistance, and stability, making them highly practical.
