Xinyang National Standard Fire Retardant Coating Factory

The function of fireproof coating is mainly reflected in the following aspects:
1. * * Flammability or incombustibility * *: The fireproof coating itself is incombustible or incombustible, which can prevent the protected substrate from directly contacting with the air, thus delaying the ignition of objects and reducing the burning speed.
2. * * Heat insulation and heat resistance * *: In addition to its own flame retardant or non combustible properties, the fireproof coating also has a low thermal conductivity. When the fire retardant coating is heated, its coating can delay the transmission rate of high temperature to the substrate, effectively delaying the transmission of flame temperature to the protected substrate.
3. * * Release incombustible inert gas * *: during heating, the fireproof coating will decompose into incombustible inert gas. These gases can dilute the combustible gases decomposed from the protected objects when heated, further reducing the possibility of combustion or slowing down the combustion rate.
4. * * Interrupt the chain reaction * *: The nitrogen-containing fireproof coating will decompose into NO, NH3 and other groups when heated. These groups can combine with organic free radicals to interrupt the chain reaction and help reduce the system temperature.
5. * * Thermal insulation layer formed by expansion and foaming * *: the expansion fire retardant coating will expand and foam when heated to form a carbon foam thermal insulation layer. This layer can seal the protected object, further delay the transfer of heat and substrate, and effectively prevent the object from burning or strength reduction due to temperature rise.

Hebei Jinteng Fireproof Material Co., Ltd. is well aware of the importance of fireproof coating in preventing fire spread and winning escape time. Therefore, since its inception, the company has invested a lot of human, material and financial resources to research and develop fireproof coatings that meet national standards and performance. After years of technical accumulation and market inspection, Jinteng's national standard fireproof coating has formed a complete product series to meet the diversified needs of different scenarios and customers.

Spraying is adopted. Spray the primer. In order to improve the bonding strength between the coating and the steel beam base course, the coating shall be fully mixed before construction. After construction, the second construction shall be carried out 18~24 hours after the surface is dry. The coating thickness shall be controlled as required until the specified thickness is reached. The construction interval is more than 18~24 hours, and the construction environment temperature is 0~40 ℃. The substrate temperature is 5~45 ℃. The relative humidity of the air is not more than 90%, the air on the construction site is well ventilated, and the wind speed is not more than 5m/s. It is not suitable for outdoor operations or when the surface of construction components is dewed.
