Ceramic high temperature anti-corrosion coating solves the problem of corrosion and wear of chimneys.

With or without heat exchangers (GGH), SO2, SO3, NOX, and other corrosive gases are prone to react with water vapor to produce dilute acid solutions (e.g. sulphate, sulphuric acid, nitric acid, etc.) at low temperatures and humidity. Drips attached to the flue, the chimney steel structure to form pitting corrosion, crevice corrosion, stress corrosion and other strong corrosion effect, because compared with the same concentration of acid solution, the temperature (40 degrees C to 80 degrees C) of dilute acid corrosion is 3 to 8 times higher.

experts pointed out that from a thermodynamic point of view, the smoke humidity, high density, resulting in a decrease in the self-absorption capacity of the flue gas, not easy to spread upward; Under the action of positive pressure, the ability of flue gas to penetrate into the inner cylinder through the lining cracks is enhanced, resulting in increased corrosion, and the high-speed solid particle flow in the flue gas has an erosion wear effect on non-metallic lining materials and metal components, and corrosion and wear become the main factors leading to the safety hazards and low service life of the desulfurization system.
coal-fired fumes from coal-fired power plants contain a large number of SO2, SO3, HCl, HF and other corrosive gases, which combine with water vapor in the flue gas to produce acid and deposit on the chimney barrel wall, although the concentration is low, but the corrosion is higher than the thick acid. Comprehensive cost, construction duration and cost, expectation performance and corrosion-proof life requirements and other conditions, the current market common anti-corrosion materials are somewhat defective, people often through thick coating to meet the needs of chimney corrosion prevention. For new anti-corrosion materials such as Beijing Zhisheng Weihua Chemical Co. , Ltd. production of ZS-1041 flue gas anti-corrosion
coating
, ZS-1042 desulfurization anti-corrosion special anti-corrosion coating although good performance, the price is appropriate, ZS flue gas anti-corrosion coating on the major power plants on the desulfurization energy-saving environmental protection work, after many years of operation confirmed that the performance of the coating is excellent.
chimney flue, bracket, absorption tower, spray tower material, lining due to the corrosion of smoke all affect the service life and cost of the device. Chimney flue, bracket, absorption tower, spray tower lining is concrete, cement, pouring materials, metal materials, rubber lining brush ZS-1041 flue gas anti-corrosion coating and ZS-1042 desulfurization special anti-corrosion coating. ZS-1041 flue gas anti-corrosion coating, acid and alkali wear resistance, waterproof and impermeable effect is good. ZS-1042 desulfurization special anti-corrosion coating acid-base resistance, good impact resistance. ZS-1041 flue anti-corrosion coating can withstand up to 600 degrees C high temperature, can be long-term operation below 750 degrees C, acid concentration range, good anti-penetration effect, excellent wear resistance, basic can cope with all the current flue anti-corrosion conditions. ZS-1042 desulfurization special anti-corrosion coating using the world's most advanced inorganic -organic chelating high temperature and high pressure synthetic solution, with technology to lead the anti-corrosion Weihua anti-corrosion coating temperature of 750 degrees C, strong adhesion, high flexibility, acid-base corrosion resistance, coating fillers using corish, scale quartz, scale graphite, scale glass powder, red column stone, etc. After calcination crystallization, the stability of the properties in the acid-base environment is more than 3 times higher than before calcination, so that through the interaction and synergy between various materials, strong combination into an efficient anti-corrosion coating - ZS-1042 desulfurization special anti-corrosion coating, chemical corrosion, physical corrosion and electrochemical corrosion is very good, coating line expansion coefficient of 8 x 10-6/C, adhesion can reach more than 10Mpa. ZS-1042 desulfurization special anti-corrosion coating can resist the strong abrasiveness of the particle slurry at the bottom of the desulfurization tower, resist the corrosion of the desulfurization slurry strong acid-alkali, resist the multiphedration corrosion of the desulfurization tower gas solidified liquid, high-speed spray friction, vibration corrosion, acid dew point corrosion, halide corrosion and other corrosion friction.
