Chimney flue anti-corrosion coating brushing anti-corrosion, from the flue gas composition analysis, flue gas in the corrosion of steel components are mainly HCl, HF and SOx, CO2, water vapor and so on. SNT-505 flue gas anticorrosive coating construction process proved that as long as the chimney outlet temperature is lower than 180 ℃, and the flue gas flow rate is slow, all or most of the chimney wall corrosion occurs; In addition, if no wind or humidity In the larger weather, the SO2 in the flue gas will settle around the outlet of the chimney, forming thin H2SO4, corroding the inner and outer walls of the chimney; SO2 is not only corroded to ordinary carbon steel at high temperatures, but also carbon steel decarburization , So that the entire steel loose, to the final formation of brittle fracture.
When the chimney flue gas temperature below 280 ℃, chimney flue gas hot and humid water vapor is easy to condensation, attached to the inner wall of the chimney, sulfur-containing flue gas and dew on the wall will be combined into SO2, H2SO3 or dilute H2SO4, these chemical media on the various Chimney walls have a strong corrosion damage. Brick or reinforced concrete chimney wall corrosion, was powder or massive peeling. Among them, the reinforced concrete chimney is corroded by the formation of unbonded strength of calcium sulfate or calcium aluminum sulfate, so that the loss of protective layer of steel, by the dilute acid corrosion, reduced cross-section, reduced strength, resulting in reinforced concrete loss of unique features. Therefore, the high concentration of acid gas chimney, must be chimney anti-corrosion treatment, brushing SNT-505 flue gas anti-corrosion coating to extend its service life.
Schneider anti-corrosion research and development personnel, according to hundreds of flue gas flue scene bold innovation, the use of new materials, combined with high-tech, Zibo Schneider Anticorrosion Technology Co., Ltd. developed SNT-505 flue gas corrosion coating The successful application of the coating, the coating of high temperature flue gas, anti-chimney flue condensate corrosion effect, high temperature, high hardness wear, acid and alkali resistance, expansion coefficient is good, the use can be up to 10 years. SNT-505 flue gas chimney anti-corrosion coating using inorganic polymer-based interpenetrating polymer as a film-forming material, SNT-505 flue gas chimney anti-corrosion coating, the main components of the coating using nano-powder, ceramic beads, silicon carbide, Boron nitride, fine-grained alumina, ultra-fine zinc oxide, titanium oxide, made of cermet function Schneider refined filler to improve the wear-resistant, corrosion resistance. Use inorganic fibers to enhance the impact resistance of the coating. With the appropriate pigments, solvents, additives and adding wear-resistant enhancer. SNT-505 flue gas chimney anti-corrosion coating and the traditional polyurea, foam glass tiles, glass scales, OM paint or clay, it is high temperature, coating light, high hardness, long life, durability, Can be used for more than 10 years, the process of damage in the coating can be easily repaired. In the preparation, coating and coating process of the environment without pollution.
1, chimney anti-corrosion coating, SNT-505 flue gas chimney anti-corrosion coating has excellent resistance to chemical corrosion, especially the ability to condense sulfuric acid corrosion;
2, chimney anti-corrosion coating, SNT-505 flue gas chimney anti-corrosion coating has a very high resistance to water vapor permeability;
3, chimney anti-corrosion coating, SNT-505-type flue gas chimney anti-corrosion coating has excellent high temperature and temperature resistance of the performance, to meet the long-term working temperature fluctuations in the 45 - 600 ℃, short-term operating temperature of 800 ℃, Protection action temperature 850 ℃;
4, chimney anti-corrosion coating, SNT-505-type flue gas chimney anti-corrosion coating coating also has high resistance to flex and thermal expansion and resistance to resistance, although the steel chimney is reinforced but still inevitable in the operation of vibration;
