      What is the fireproof principle of steel structure fireproof coating?

      The fire prevention principle of steel structure coating has three: one is the coating on the steel base material has a shielding effect, so that the steel component is not directly exposed in the flame high temperature. The second is the coating after heat absorption part of the material decomposition of water vapor or other gas, play the role of heat consumption, reduce the flame temperature and combustion speed, dilute oxygen. The third is that the coating itself is porous, light and forms carbonized foam layer after being heated, which prevents the heat transfer to the steel substrate quickly, delays the reduction of the strength of the steel substrate, and thus improves the fire-resistance limit of the steel structure.

      The main varieties of thin coated steel structure fire retardant coating are LB steel structure fire retardant coating, SG- 1 steel structure fire retardant coating, SB - 2 steel structure fire retardant coating, 55 -1 steel structure fire retardant coating. The main types of thick-coated fireproof coatings for steel structures are as follows:

      LC steel structure fire retardant coating,ST] A,IG276,ST 86,SB 1 1.SG 2 steel structure fire retardant coating, etc.
