First, the fire time is long: the focus of fire retardant coating is the problem of fire resistance limit, that is, the general fire resistance time. In case of fire, the non flammability and low thermal conductivity of the coating form a fire-resistant and heat insulation protective layer, which can improve the fire resistance of the steel structure. After the thick steel structure fire retardant coating is sprayed on the surface of steel members, the fire-resistant and heat insulation protective layer is formed by the non flammability and low thermal conductivity of the coating itself in case of fire, so as to effectively improve the fire resistance limit of steel structure. According to the national standard, the fire resistance time of thick steel structure fireproof coating can reach 3 hours.
Second, health and environmental protection: health and environmental protection is an eternal theme in that field, just like the coating industry. There are three kinds of fireproof coatings for steel structures: ultra thin, thin and thick. Only thick fireproof coatings for steel structures are based on the principle of inorganic compounds. The advantage of inorganic compounds is that they will not produce chemical reactions. They are fire-resistant and heat-insulating based on physical principles. The product has the characteristics of no corrosion of steel, no chemical reaction with any anti-corrosion primer, no pungent smell, light coating weight (structure load weight is relatively light), large unit coating area, no smoke when meeting fire, no harmful gas release, etc., and no harm to human body. It is a healthy, environment-friendly and harmless fireproof coating.
Third, good prospects: a product will get better development only on the premise of promising. In recent years, with the rapid development of the construction industry, all kinds of steel structures are springing up everywhere, and the demand for thick steel structure fire retardant coatings is also increasing year by year. Under this prospect, the development prospect of thick steel structure fire retardant coating will be better and better.
