Inorganic high temperature anticorrosive coatings become the focus of research and development of coatings enterprises
The heat source of industrial high temperature environment is mainly the burning of various fuels (such as coal, oil, natural gas, gas, etc.), mechanical rotating friction (such as electric motor, machine tool, grinding wheel, chainsaw, etc.), so that mechanical energy becomes heat and part comes from heat. Chemical reaction. High temperature In general, the material is more than 250 °C. If the material is not well utilized and protected, the damage caused by heat will be immeasurable. Each material has its own characteristics. The heat-resistant material is easy to rupture along the crystal at high temperature. If the material has more grain boundary impurities at high temperature, the melting point is lower, the diffusion is easier, and the corrosion oxidation is intensified. When the temperature at which the grain boundary strength is equal to the internal strength of the grain is called the equi-cohesive temperature (ECT), if the material is not protected, the stress will gradually decrease if the material is subjected to a fixed strain at a high temperature. This phenomenon is called stress relaxation. For materials at high temperatures, the material is subjected to a fixed stress and its strain is gradually increased. The material is stressed at high temperatures, and the phenomenon that strain increases with time is called creep. Therefore, the material should be painted with high-temperature anti-corrosion paint at high temperature, and it should be protected in time to give industry and humans a safety. The main difference between inorganic high-temperature corrosion coating and conventional anti-corrosion coating is temperature and high temperature. The technical content is high, the development technology is difficult, the use environment is complex, the coating involves many aspects of technological progress and other raw materials supporting development, inorganic high-temperature coating research and development. Not only relying on chemical knowledge and experience, but also on multidisciplinary knowledge and convergence of electronics, physics, ecology, machinery, instrumentation and management. The synthesis of inorganic high-temperature coatings, the application of high-efficiency dispersants and rheological additives, the development of new anti-corrosion and anti-seepage pigments and fillers, the application of advanced construction tools, construction and maintenance technology, and on-site inspection technology all need to be applied to inorganic high temperature. Anti-corrosion coating and painting. Therefore, the development level of inorganic high-temperature anti-corrosion coatings, how to achieve performance, has become a symbol of a country's scientific and technological level, and has become a symbol to measure the advanced technology of coatings. At present, large-scale paint companies in various countries have focused on research and development of inorganic high-temperature anti-corrosion coatings, focusing on manpower, material resources, financial resources, etc., to accelerate the development of coatings. Domestic large-scale anti-corrosion coatings company, Beijing Zhisheng Weihua Chemical Co., Ltd., has been at the forefront of the research and development of inorganic high-temperature anti-corrosion coatings. Its ZS-811 high-temperature anti-corrosion coating developed by the company has a temperature resistance of up to 1800 degrees Celsius and is long-lasting. Time barbecue, water-based inorganic self-curing heat-resistant paint, salt spray resistance, good anti-aging performance, no harm to the human body, no toxicity, no odor, no burning and explosion hazard, its physical properties, chemical properties and performance have reached the international advanced level . After eight years of research and development, during the research and development of the coating project, it received strong support from the Beijing Municipal Government, some university scholars in Beijing, and the R&D Institute. Science and technology represent life, build high-tech products, master core technologies, and enrich the country and the people.
