Now some fire supervision and law enforcement officers have inspected fire products and made a series of experiments on fire panels. Experiments show that when burning at high temperature, the steel plate coated with qualified fire retardant coating will expand continuously, forming a barrier, winning precious escape time and organizing rescue operations for people.
"In case of fire, qualified fire products can play a role in extinguishing or controlling the further expansion of fire. It's like a fire extinguisher that can extinguish the original fire and control the danger. However, some illegal elements have made some counterfeit and inferior fire products, which seriously threaten people's lives and property security. Experts said that the real fire retardant coating can play a very good effect of fire prevention and thermal insulation, can effectively flame retardant 60 to 120 minutes, usually used in the construction of flammable materials and ventilation pipes, cables, wires, building steel structures and other aspects of fire retardant combustion protection. "In this way, in case of fire, buildings with qualified fire retardant coatings will have better fire protection performance and provide more precious escape time for people."
Fumeijia Fire Board Wholesale Manufacturer said, "Fire site temperature is generally more than 800 to 1000 degrees Celsius. Today, we simulate 500 degrees Celsius. At 500 degrees Celsius, the steel structure will deform. The heated steel plate not only conducts heat, but also causes ignition of nearby combustible materials. If it is a steel structure, the building will lose its bearing capacity, which is unsafe and may collapse. After the qualified fire retardant coatings are heated at high temperature to form a protective layer, the experimental personnel and the steel plate coated with fake and inferior fire retardant coatings continue to burn. After being heated at high temperature, the surface of steel structure changes slightly, and the surface coating cracks and peels off. The experimenter said, "The fake and inferior coatings have almost no change after fire, no flame retardant and heat insulation function, it is similar to bare steel temperature rise time."
The ultra-thin fire retardant coatings are mainly composed of base materials, flame retardant fillers, pigments and additives. According to the fire-retardant mechanism, the fire-retardant coatings for ultra-thin steel structures belong to the intumescent fire-retardant coatings, according to the wholesale manufacturers of fire-retardant panels. The mechanism of fire prevention is that the coating absorbs heat and expansion and foam under the action of fire, releases non combustible gas to terminate free radicals oxidation or dilute oxygen surface coating, and foam layer low heat conduction and absorption and other factors play a role in fire prevention.
