    Core tip: as a building material, steel has some unavoidable defects in fire protection Its mechanical properties, such as yield point, tensile strength and modulus of elasticity, will drop sharply due to the rise of temperature At this time, steel structure fire retardant coating is needed The following small edition will introduce how steel structure fireproof coating works and how much is the construction price of steel structure fireproof coating How about fire retardant coating for steel structure? Steel structure usually loses its bearing capacity in the temperature of 450-650 ℃, and great deformation occurs, which leads to bending of steel column and steel beam As a result, it can not continue to be used due to excessive deformation Generally, the fire endurance of unprotected steel structure is Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating House News: as a building material, steel has some unavoidable defects in fire protection Its mechanical properties, such as yield point, tensile strength and elastic modulus, will decline sharply due to the rise of temperature At this time, steel structure fire retardant coating is needed The following small edition will introduce how steel structure fireproof coating works and how much is the construction price of steel structure fireproof coating How about fire retardant coating for steel structure? Steel structure usually loses its bearing capacity at 450-650 ℃, which causes great deformation and bending of steel column and steel beam As a result, it can not be used because of excessive deformation Generally, the fire endurance of unprotected steel structure is about 15 minutes The length of this time is also related to the heat absorption rate of the component In order to overcome the shortcomings of fire protection in practical application of steel structure materials, fire prevention treatment must be carried out Its purpose is to increase the fire resistance limit of steel structure to the limit range specified in the design code There are various measures to prevent deformation collapse of steel structure caused by rapid temperature rise in the fire The key is to adopt different methods according to different situations, such as using heat insulation and refractory materials to block the flame to burn steel structure directly, reducing the speed of heat transfer and delaying the time of temperature rise and strength weakening of steel structure But no matter what method is adopted, its principle is consistent The steel structure is set in the wall or ceiling composed of refractory materials, or the components are wrapped in the gap between the two walls As long as a little refractory materials are added or not, the purpose of fire protection can be achieved This is the most economical way to prevent fire Steel structure fireproof coating is used to protect components This method has the advantages of good fireproof and heat insulation performance, construction is not limited by steel structure geometry, generally does not need to add auxiliary facilities, and the coating is light in quality, and has a certain aesthetic decoration effect It belongs to modern advanced fire prevention technical measures There are more and more high-rise steel structure buildings, especially some super high-rise buildings, which use more steel structure materials Once a fire accident occurs in a high-rise building, the fire can not be put out in a short time, which requires us to increase the fire protection of building materials in the architectural design, so as to enhance its fire resistance limit, and make necessary emergency plans in the building interior to reduce casualties and property losses How much is the construction price of steel structure fire retardant coating? There are ultra-thin, thin and thick types of steel structure fire retardant coating Generally, the ultra-thin type is used for two hours of fire resistance, and the price is about 12 to 14 pieces Of course, this is the price of regular and qualified fire retardant coating, not to mention the price of non fire resistant water cargo The above is how about the steel structure fireproof coating and how much is the construction price of the steel structure fireproof coating I hope it can help us to protect the building steel In addition, in actual use, in order to ensure the fireproof and other performance of fire retardant coating, transparent coating is generally required.
