What is the principle of fire fireproof coatings is?
Guangzhou Steel tells you: Guangzhou fireproof coatings fire principle, there are three: First, the coating of steel substrates act as a shield, the steel member will not be directly exposed to a high temperature flame. Second, after the heat-absorbing coating portion of the material released by the decomposition of water vapor or other gas not break, play burn calories, reduce the flame temperature and combustion rate, dilution effect of oxygen. Third, after the formation of the coating itself porous carbonized foam layer of light and heat, preventing rapid heat transfer to the steel substrate, delayed lowering steel substrate strength, thereby increasing the fire resistance of steel structures.
The main varieties thin coating of steel structure fire retardant coating has LB intumescent fire retardant coating, SG - 1 intumescent fire retardant coating, SB-2 intumescent fire retardant paint, 55-1 intumescent fire retardant coating. Thick coating steel structure fire main varieties are:
LC fireproof insulation coatings, ST] a A, IG276, ST-86, SB-2 1.SG a fireproof paint.
