Coating knowledge: fire retardant coating for steel structure: strong protective clothing for steel members

Core tip: the steel structure has the characteristics of high strength, light weight, improved efficiency and speed, and is widely used in the construction industry Moreover, the steel structure has good ductility and seismic resistance, short construction time, and is more and more used in high-rise building construction However, the high temperature resistance of steel structure is not very good In the case of fire, only a quarter of an hour is needed, and the temperature of steel structure will rise to more than 540 degrees Under high temperature, steel structure is easy to deform, which will lead to accidents, so the fire retardant coating for steel structure is produced The principle of fireproof and heat insulation for ultra-thin or thin steel structure fireproof coating is that the fireproof coating layer expands and foams when it is heated, forming foam, and the foam layer is not Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint House News: steel structure has the characteristics of high strength and light weight, which improves efficiency and speed It has been widely used in the construction industry Moreover, steel structure has good ductility and seismic resistance, short construction time, and is increasingly used in high-rise building construction However, the high temperature resistance of steel structure is not very good In the case of fire, only a quarter of an hour is needed, and the temperature of steel structure will rise to more than 540 degrees Under high temperature, steel structure is easy to deform, which will lead to accidents, so the fire retardant coating for steel structure is produced The principle of fireproof and heat insulation for ultra-thin or thin steel structure fireproof coating is that the fireproof coating layer expands and foams when it is heated, and the foam layer not only isolates the oxygen, but also has good heat insulation performance because of its loose texture, and it can delay the heat to the speed of the protected substrate According to the principle of physical chemistry, the process of coating foam layer is expanded by heat absorption, which also consumes the heat of combustion, which is beneficial to reduce the temperature of the system These aspects can make the fire retardant coating produce remarkable fire protection and heat insulation effect The fire insulation principle of thick steel structure fire retardant coating applied on steel members is that the coating basically does not change in volume when the fire retardant coating is under fire, but the thermal conductivity of the coating is very low, which delays the speed of heat transfer to the base material to be protected The coating itself of the fire retardant coating is non combustible, which acts as a barrier for steel members and prevents heat radiation, and avoids the direct attack of flame and high temperature on steel members [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
