What is the thickness of the thick fireproof coating?
Generally do not ask what the thickness of the bar, painted three times on the OK you
Fireproof materials are refractory time as the standard, the thickness requirements of no standard. In other words, all fire protection materials are required for inspection, testing agencies will give the sample rating, to the design requirements of the fire partition can be. In addition, some fire retardant coating manufacturers will have the requirements of the thickness of the fire coating to reach the description of the thickness can only meet the fire requirements, but the quality inspection agencies are invalid, quality inspection still need professional testing report was recognized.
Thin steel structure Fireproof coating: 2.5 hours of fire resistance, the thickness is 4.9mm 2.0 hours of fire resistance, the thickness is 3.5mm1.5 hours of fire resistance, the thickness is 1.75mm1.0 hours of fire resistance, the thickness is 1.17mm thick Coated fire retardant coating is generally between 8-45mm brushing, spraying construction should be divided to complete the thickness of each spray should be 5 ~ 10mm, must be in the previous dry or cured, and then spray again. Spray coating protection, spraying the number of times with the thickness of the coating should be based on the requirements of the construction design of the twitching of the tumbling of the pile, The first general brushing 3-5mm, after each in between 7-10mm. It should be noted that the first time after drying or curing before the second brushing. Until the thickness of the construction requirements is reached.
According to GB-2002 "steel structure fire retardant coating" provisions: thick: coating thickness of 745mm in the fire retardant coating: coating thickness of 3-7mm in the fire retardant coating: the thickness of less than 3mm coating thickness of the fire Type fire retardant coating is non-intumescent steel structure fire retardant coating, generally by: binder, inorganic refractory insulation materials, additives and other components. The coating does not expand in the case of fire, through its own insulation performance of the protected components to improve the fire resistance time.
