    Core tip: fire retardant coating, also known as fire retardant coating, can be divided into two major categories according to its use object: facing type and steel structure fire retardant coating According to the change state of coating after fire, it can be divided into two major categories: expansion type and non expansion type At present, as a form of high-rise building structure, steel structure is widely used in the construction industry, especially in super high-rise and long-span buildings, because of its high strength, light weight, good extensibility, earthquake resistance and short construction period Beijing Zhisheng Weihua Chemical Co., Ltd is the manufacturer of high temperature and heat insulation coating Its ZS-1 high temperature and heat insulation coating is a kind of water-based ring 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 home news: fire retardant coating, also known as fire retardant coating, is mainly divided into two categories: facing type and steel structure fire retardant coating According to the change state of coating after fire, it can be divided into two categories: expansion type and non expansion type At present, as a form of high-rise building structure, steel structure is widely used in the construction industry, especially in super high-rise and long-span buildings, because of its high strength, light weight, good extensibility, earthquake resistance and short construction period Beijing Zhisheng Weihua Chemical Co., Ltd is the manufacturer of high temperature and heat insulation coating Its ZS-1 high temperature and heat insulation coating is a kind of water-based environmental protection coating, with a thermal conductivity of 0.03w/m.k, temperature resistance of 1800 ℃, long-term fire-resistant barbecue, which can effectively inhibit all kinds of heat transfer and radiation, and the heat insulation and heat insulation inhibition efficiency can reach 90% When the coating is 8mm thick on the surface of the object at 1100 ℃, the temperature of the object surface can be reduced from 1100 ℃ to less than 100 ℃ When the coating is only 6mm thick on the external surface of industrial furnace, furnace, blast furnace and steel structure, the heat loss can be reduced by more than 30% ZS-1 coating has the advantages of fire-retardant, insulation, wear-resistant, acid and alkali resistant, light weight, good heat insulation effect, convenient construction, long service life, etc With the development of China's urban scale, the application of steel structure in China's construction industry has a very broad prospect However, due to the fact that the steel structure does not burn itself, the fire and heat insulation protection of the steel structure has been ignored for a time Relevant tests and statistics show that the fire resistance of the steel structure is worse than that of the masonry structure and reinforced concrete structure The mechanical strength of steel decreases with the increase of temperature At about 5000 ℃, its strength decreases to 40% - 50% The mechanical properties of steel, such as yield point, compressive strength, elastic modulus and load capacity, all decrease rapidly and lose the supporting capacity, which leads to the collapse of buildings Therefore, it is imperative to protect the steel structure Steel structure fire retardant coating is applied or sprayed on the surface of steel structure to play the role of fire protection and heat insulation, to prevent the steel from rapidly heating up in the fire and reducing the strength, and to avoid the collapse of the building due to the loss of support capacity of steel structure With the development of coating industry to the direction of performance, high energy saving and low pollution, the development of new inorganic environmental friendly fire retardant coating will become the development direction of fire retardant coating in the future Zs-11 intumescent high temperature and heat insulation coating developed by Beijing Zhisheng Weihua Chemical Co., Ltd is in the leading position in the world in coating technology, and the company has core technology patents The coating adopts Zhisheng Weihua's two-stage solid-state curing film-forming solution as the film-forming material The coating filler is made of high-temperature inorganic nano materials - alumina, zirconia, carbon fiber, hollow carbon nanotubes, expanded graphite, silicon carbide, etc after high-temperature and high-pressure finishing The coating can expand after being heated, and the volume expansion rate of the coating can be more than 5 times After the coating expands, numerous independent vacuum layers can be formed in the coating, and the coating will not fall off after being heated and expanded The temperature resistance of the coating can reach 2000 ℃, and the thermal conductivity of the fully expanded coating layer can reach 0.022w/m K (measured at 70 ℃, the coating is cooled after being heated at high temperature) Zs-11 intumescent heat insulation coating is solidified by solid-state principle, and it can well control the formation and growth of crystal It can be painted on any organic or inorganic material, with good adhesion The coating can be heated to a high temperature of more than 1000 ℃, and the coating is fully expanded, with excellent thermal conductivity and the best heat insulation effect; After curing, due to the selection of inorganic nano fillers, the coating has good acid and alkali resistance, can well protect the substrate from high temperature corrosion and oxidation, has high smoothness and hardness, good wear resistance, and is resistant to open fire for a long time The fire rating can reach class A, and the coating construction is convenient It is a veritable water-based fire retardant coating for steel structures The development of industry, the rise of solvent price, the increase of energy consumption and the strict control of waste discharge, the development and research of solvent based coatings which mainly replace toxic organic solvents for waterborne coatings have become an important aspect of the development of coating field in the world, and zs-11 intumescent high temperature heat insulation coating undoubtedly takes the lead in the world [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
