Hebei XinjinTeng Fireproof Materials Co., Ltd. is a manufacturer of fireproof materials, with their products predominantly used in construction. A variety of fireproof materials play a crucial safety role in modern fire protection.
        

        The fire-retardant principle of fire-resistant coatings can be roughly summarized into the following five points:

The fire-retardant coating itself is non-combustible, preventing the protected base material from directly contacting oxygen in the air.

Fire-resistant coatings have a lower thermal conductivity coefficient, slowing the rate of heat transmission to the base material.

Fire-retardant coatings decompose into non-flammable inert gases when heated, diluting the flammable gases released by the protected object, making it less likely to ignite or burn at a slower rate.

Nitrogen-containing flame-retardant coatings decompose upon heating to release groups such as NO and NH3, which then react with organic free radicals, breaking the chain reaction and lowering temperatures.

⑸ The expandable fire-retardant coating expands and foams upon heating, forming a carbonaceous foam insulating layer that encapsulates the protected object. This delays the transfer of heat to the base material, preventing the object from igniting, burning, or experiencing a decrease in strength due to temperature rise.
