Xinjiang steel structure fireproof coating ultra-thin structure fireproof coating

Ultra-thin steel structure fireproof coating refers to the coating thickness within 3 mm (including 3 mm), good decorative effect, expansion and foaming at high temperature, fire resistance of steel structure generally within 2 h. This type of steel structure fireproof coating is generally a solvent-based system, which has the characteristics of superior bonding strength, good weather resistance and water resistance, good leveling, and good decorative properties; it slowly expands and foams when it is exposed to fire to form a dense and hard fireproof insulation layer. The fireproof layer has strong fire impact resistance, which delays the temperature rise of the steel and effectively protects the steel components. The construction of ultra-thin intumescent steel structure fireproof coatings can be applied by spraying, brushing or roller coating, and is generally used on building steel structures with fire resistance requirements within 2 hours. A new variety of ultra-thin steel structure fireproof coatings with fire resistance performance of 2 hours or more has appeared. It is mainly based on the special structure of polymethacrylate or epoxy resin, amino resin, chlorinated paraffin, etc. as the base material. Mixture, with high degree of polymerization ammonium polyphosphate, dipentaerythritol, melamine, etc. as a fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory materials, 200 # solvent oil as a solvent compound.

Xinjiang steel structure fireproof coatings Various types of light steel structures, grids, etc. mostly adopt this type of fireproof coatings for fire protection. Due to the ultra-thin coating of this type of fire-resistant coating, the use of thicker and thinner steel structure fire-resistant coatings is greatly reduced, which reduces the total cost of the project, and enables the steel structure to be effectively fire-protected and has a good fire-proof effect.
