Industrial anti-corrosion coatings keep metals from corroding and keep emissions environmentally friendly

China Coatings Online News Information: The national environmental protection policy is tight, green water green mountains, energy-saving and environmental protection coatings have become the focus of development, and anti-corrosion coatings are more widely used, more practical needs. In recent years, low-polluting anti-corrosion coatings in the high anti-corrosion development of the fastest, the most widely used anti-corrosion coatings, there is now a solid content of 100%, that is, solvent-free coatings and temperature-resistant 2300 degrees C high temperature anti-corrosion coatings to promote the trend.
Solvent-free coatings, also known as active solvent coatings, are made of synthetic resins, curing agents and active solvents, all components of the formulation system, except for a small amount of volatilization, are involved in the reaction curing into film, less environmental pollution. High temperature anti-corrosion coatings, temperature resistance up to 2300 degrees Celsius, short-term heat can be heated to more than 2500 degrees Celsius, ZS-811 high temperature anti-corrosion coatings can withstand fire and high temperature long-term oxidation corrosion, acid-base high temperature erosion, heat shock and wear resistance, anti-corrosion technology has reached the world's advanced level.protection of metal materials by anti-corrosion coatings mainly includes shielding, corrosion protection, cathode protection and comprehensive protection of the above three methods. High temperature anti-corrosion coatings in normal temperature and high temperature are not VOC production, environmental protection inorgeable ceramic coatings, anti-corrosion effect, water-based coatings, painting on the metal surface to form an inert isolation layer, the metal material and the environment isolation, to curb the environment of water, oxygen, chloride and other corrosive media and metal contact, thereby preventing corrosion reaction. Zhisheng Weihua anti-corrosion coatings grew into anti-corrosion coating industry standard, ZS high-temperature anti-corrosion coatings more use of anti-corrosion conditions, anti-corrosion effect of good long-term corrosion resistance, has been recognized by the national project anti-corrosion. With the development of industrial technology, corrosion and corrosion protection are common in petrochemical, energy, power, metallurgy, aerospace and other fields.boiler in the combustion process of coal, sulfur is oxidized to SO2, the volume concentration of SO2 in flue gas is about 368ppm-2579ppm, SO3 content is 7ppm-52ppm, smoke The gas temperature is about 120-140 degrees C, the temperature of the flue gas after wet desulfurization is about 50 degrees C, and after the GGH heat exchanger is set, the flue gas temperature can be raised to about 80 degrees C, and the water vapor content is about 10%-11%. Flue, chimney, desulfurization, dust anti-corrosion is the difficult point in corrosion protection, requires anti-corrosion materials at the same time to achieve high temperature, acid and alkali resistance, corrosion resistance, moisture resistance, wear and impact resistance, smooth surface, not easy to grow cracks, expansion coefficient is good, not easy to fall off and so on the above requirements, this is a comprehensive assessment of anti-corrosion materials, strict review, to ensure that the flue, chimney, desulfurization, dust removal and anti-corrosion for a long time.The Ministry of Environmental Protection has issued a Notice on the Implementation of the Comprehensive Compliance Emission Plan for Industrial Pollution Sources, which requires that by the end of 2017, eight industries, such as steel, pyration, cement, coal, paper, printing and dyeing, sewage treatment plants and waste incineration plants, have achieved remarkable results in the implementation of the compliance plan, the pollutant emission standards system and environmental supervision mechanism have been further improved, and a good atmosphere for environmental compliance has basically taken shape. By the end of 2020, all kinds of industrial pollution sources will continue to meet the emission standards, environmental governance system will be more sound, environmental compliance will become the norm. Industrial energy conservation has become the primary topic, reduce pollution, improve product value, enhance the competitiveness of the enterprise market, high-temperature functional anti-corrosion coatings have become a hot material in the industrial market. ZS high temperature function anti-corrosion coating on the market, is based on the original high temperature paint to do technical upgrades, higher technical content, pollution hazards are almost zero.
