Abstract: Flame retardant board, also known as flame retardant board, flame retardant plywood, flame retardant plywood, etc., is based on plywood. It has good moisture absorption and breathability of solid wood, and it is easy for the flame retardant to be evenly distributed inside the wooden material. , overcomes the shortcomings of ordinary plywood that is easy to burn, and can provide effective flame retardant properties. It is mainly used for public building decoration projects with high fire protection requirements, or high-end residential building decoration projects. So how does the flame retardant board work? Generally speaking, there are two main types: base material flame retardant, surface and bottom layer flame retardant. Let’s take a look at the introduction. What is flame retardant board
Flame retardant board is also known as flame retardant board, flame retardant plywood, flame retardant plywood, etc. It is based on plywood and has good moisture absorption and air permeability of solid wood, making it easy for the flame retardant to be evenly distributed in the The interior of the wooden material overcomes the shortcomings of ordinary plywood that is easy to burn, and can effectively perform flame retardant properties. It is similar to the plywood production process and consists of multiple flame retardant treatments.
Working principle of flame-retardant board
1. The base material is flame-retardant
The environmentally friendly material selected has long-lasting flame retardant effect, good resistance to loss, and is waterproof and moisture-resistant. Type flame retardant, after the board substrate is treated under special conditions, the flame retardant can be fully combined with the wood fiber. During the burning process, the flame retardant board can effectively dilute the combustible gas, isolate the air and fire source, and Change the cracking process of wood when it is not burning, control the burning trend and process of the floor, and finally achieve the purpose of flame retardancy;
2. Surface and bottom layer flame retardancy
The surface adopts patented technology. Some inorganic tempered materials are added to the surface layer, which can not only increase the impact resistance and wear resistance of the floor, but also give the floor a different flame retardant effect; and a fireproof board is added to the bottom layer, which is both It is waterproof, moisture-proof and fire-retardant.
What are the advantages and disadvantages of flame-retardant boards?
Advantages of flame-retardant boards
1. First of all, flame-retardant boards can prevent the spread of fire and help escape from the fire scene. Precious time. Flame retardant board does not mean that it will not burn, it just prevents the fire from spreading quickly.
2. Flame-retardant boards are processed on the basis of plywood. They are light, easy to process, convenient to construct and reduce costs.
3. Flame-retardant panels have good structural strength and strong bending resistance.
Disadvantages of flame-retardant boards
1. Flame-retardant boards will produce toxic gases during the combustion process. However, some major brands of flame retardant boards use advanced flame retardants to greatly reduce the production of toxic gases in fires.
2. After the flame-retardant board is flame-retardant, it will have a certain impact on the bonding strength of the board.
