The fireproof layer has a strong fire-resistant impact property, delaying the temperature rise of steel and effectively protecting steel components. The construction of ultra-thin expanded steel structure fireproof coating can be sprayed, brushed or rolled, generally used in the fire resistance limit requirements within 2 h on the building steel structure. There have been new varieties of ultra-thin steel structure fireproof coatings with fire resistance of 2 h or more, which mainly use polymethacrylate or epoxy resin with special structure and amino resin, chlorinated paraffin as the base binder, with high polymerization degree ammonium polyphosphate, Dipentaertitol, melamine dị ka usoro ezumike nka.

Since the composition of thick fire retardant coatings is mostly inorganic materials, its fire performance is stable and the long-term use effect is good, but the particles of its paint components are large, the appearance of the coating is uneven, affecting the overall beauty nke ụlọ ahụ, yabụ na-ejikarị ya maka injinia zoro ezo. This kind of fire retardant coating uses the granular surface of the material in the fire, the density is small, the thermal conductivity is low or the heat absorption of the material in the coating, which delays the temperature rise of the steel and protects the steel . This kind of fireproof coating is made of suitable inorganic binder (such as water glass, silica sol, aluminum phosphate, refractory cement, etc.), Then it is mixed with inorganic lightweight adiabatic aggregate materials (such as expanded perlite, expanded vermiculite, sea Ihe mgbakwunye na-ese, na-ese, wdg, wdg, wdg, fiber fiber. nke ọnụ ala dị ala. Spraying is often used in construction, which is suitable for indoor and outdoor concealed steel structures with fire resistance limits of more than 2 h, high-rise all-steel structures and multi-storey factory steel structures. For example, the fire resistance limit of the columns of high-rise civil buildings, general industrial and civil buildings supporting multi-layer columns should reach 3h, and the thick fireproof coating should be used to protect them.
