China Coatings Online News:
A corrosion-resistant coating can resist a variety of corrosion of acid and alkali at the same time, anti-flue gas H2S, chloride ions, sulfur dioxide, sulfur trioxide, hydrogen chloride high temperature water vapor and other media corrosion, to prevent condensate point corrosion, stress corrosion, chemical corrosion, electricity Bit corrosion, etc. , and the line expansion coefficient is high, adhesion is high, impact resistance to wear this coating is Chisheng Weihua ZS-1041 flue gas anti-corrosion coating, ceramic components, acid-base corrosion resistance, high wear hardness, temperature resistance can reach 850 degrees C, high extension coefficient.
The combustion of coal-fired fumes is acidic, if the temperature of the flue gas is lower than the acid dew point, the condensed acid will erode the internal wall of desulfurization, the installation of wet flue gas desulfurization (FGD) assembly can not be useful in addition to the so3 in the flue gas, but the flue gas temperature is Chinese New Year's EveChinese New Year's Eve down. Zhisheng Weihua flue gas anti-corrosion coating experts pointed out that the medium of flue gas corrosion is more serious in FGD installation of GGGH in FGD can not solve the internal erosion of flue gas desulfurization, because the temperature of reheated flue gas is still lower than the acid dew point of smoke.
sulfur dioxide in the flue gas during the desulfurization process is first absorbed and produced by sulphate or sulphuric acid, which eventually produces sulphates or sulfates. Sulphate and sulfate ions have strong chemical activity, resulting in corrosion of equipment. Sulfur dioxide absorption liquid, pH high value is conducive to sulfur dioxide absorption, pH value of 6, sulfur dioxide absorption effect is best. The low pH makes the absorption of sulfur dioxide inhibited, the efficiency of desulfurization is greatly reduced, when pH is 4, sulfur dioxide absorption is almost impossible, and the absorption fluid is acidic, resulting in corrosion of equipment. Beijing Zhisheng Weihua Chemical Co. , Ltd. in order to solve the problem of desulfurization of wet flue gas desulfurization pipeline, we must seek an acid-resistant anti-corrosion, temperature-resistant, high-temperature and wear-resistant adhesion and good materials, Beijing Zhisheng Weihua Chemical Co. , Ltd. exclusive production and sale of ZS-1041 flue gas desulfurization anti-corrosion paint for us to provide a better choice. So far, at least, this should be the best way to solve the problem.
acidic and corrosive gases such as sulfur dioxide, sulfur trioxide, hydrogen fluoride and hydrogen chloride in the flue gas desulfurization pipeline will not condense into acid to corrode desulfurization, and the actual life of desulfurization is much greater than thirty years. ZS-1041 flue gas desulfurization anti-corrosion coating developed by Beijing Zhisheng Weihua is made of fine materials, and ZS-1041 flue gas desulfurization anti-corrosion coating with inormeric polymer-based inter-wear network polymer as a film-forming substance, The main components of the coating using nano-powder, ceramic microbeads, silicon carbide, boron nitride, fine crystal alumina, ultra-fine zinc oxide, titanium oxide, etc., to make metal ceramic function Zhisheng Weihua special fillers to improve the wear resistance, corrosion resistance. Use inororable fibers to enhance the resistance of the coating to shock. Serve with appropriate pigments, solvents, additives and add wear-resistant enhancers.
ZS-1041 flue gas desulfurization anti-corrosion coating and traditional polysulfur, foam glass brick, glass scales, OM coating or glue, it is high temperature resistance, light coating, high hardness, long service life, good durability, service life can be up to 10 years, in the course of operation damaged coating can be easily repaired. No contamination of the environment during preparation, coating and coating.
1, ZS-1041 Zhisheng flue gas desulfurization anti-corrosion coating has excellent
resistance to chemical corrosion, especially condensed sulfuric acid corrosion; Water vapor penetration performance,
3, ZS-1041 Chisheng flue gas desulfurization anti-corrosion coating has excellent resistance to high temperature and temperature rapid change performance, to meet long-term operating temperature fluctuations between 45-600 degrees C, short-term operating temperature 8 00 degrees C, protective action temperature of 850 degrees C;
4, ZS-1041 Zhisheng flue gas desulfurization anti-corrosion coating also has a high resistance to deflection and thermal expansion resistance, can resist steel desulfurization although reinforced but still inevitable vibration in operation;
Flue gas anticorrosion coating is very good protection of desulfurized metal, in the non-metallic material lining ontological curing, the new chemical bonds and physical bonds formed by the curing reaction between large molecules, so that the polymerization and composition of large molecules change, the shortening of the distance between molecules leads to resin volume contraction. However, the coating Zhisheng ZS-1041 flue gas anti-corrosion coating desulfurization equipment lining will have a variety of different phases of the material shrinkage rate is different, including the same phase material curing reaction speed and curing heat distribution is not uniform, forming a contraction residual stress.
