Products building steel structure when the temperature rises to a critical temperature of 540 ℃, the steel will lose its carrying capacity, and for building a fire, the fire temperature is mostly between 800-1200 ℃. In general, a fire occurred in the 10 minutes, the fire temperature can rise to more than 700 ℃, and therefore the risk of fire protection without making the exposed steel members in the fire is very large. The company produces thin fireproof coatings on steel components coated on the surface of buildings and structures within, when a fire coating expansion foam insulation refractory carbide forming protective layer protective layer not only cut off from the oxygen, and heat low conductivity, heat transfer delay is the speed to protect the substrate, avoiding a direct threat to the flame and high temperature steel components, thus improving the fire resistance of steel structures. The product can meet the fire resistance of 0.5h ~ 2.5h fire protection requirements applicable to architectural design of a fire resistance rating of a single layer of support columns, beams, roof and staircases and other load-bearing member; two to four fire rating in supporting single-and multi-columns, beams, roof and staircases and other load-bearing components of steel structure. Technical standards in line with the national standard GB 14907-2002 technical indicators. Before construction process fireproof paint coating, surface rust and steel components rust primer coating shall meet the design requirements and the existing national specification should completely remove dust on the surface of steel components, grease and other debris. Construction of fire retardant paint coating should be done before the next and the interior will not be damaged by the follow-up project conditions. Construction, does not require fire protection for walls, doors, windows, and other components, such as machinery and equipment should be shielded to protect. Before coating, the coating should stir, as may be appropriate to add water when the paint is too thick, dilute to the appropriate coating, can not flowing. This product is suitable to use spray coating method. Under a pressure of 0.4 ~ 0.6MPa of air pressure of 4 ~ 8mm bucket uniformly spraying gun muzzle diameter. The first pass of the spray volume to cover the grass surface thickness is appropriate, generally no more than 1mm; former over again before the next coat after coat hard work; starting from the second pass may be appropriate to increase the thickness of each pass of brushing, but to not flowing appropriate. Reference amount 0.90kg/m2/mm
