The anti-corrosion characteristics of the barrel chimney anti-corrosion coating are introduced.

Barrel chimney exhaust pipe height of 200 meters, the inside of the chimney fire-resistant ceramic brick masonry, the outer diameter of the top cylinder 6.34 meters, the inner diameter of 5.94 meters. The outer diameter of the bottom cylinder is 18.84 meters and the inner diameter is 17.74 meters. The structure of the barrel chimney structure from the inside out is composed of special-shaped reframe-resistant ceramic brick and acid-resistant plastic mud building lining, water glass expansion pearl rock slab insulation layer, acid-resistant 1041
septic coating
isolation layer, reinforced concrete cylinder 2.2 chimney anti-corrosion design conditions.
total area of anti-corrosion of the barrel chimney and chimney interface (barrel wall area, ash platform area, flue up 5 meters, flue exit down 5 meters). Apply ZS-1041 flue gas anti-corrosion
coating
and ZS-1042 desulfurization special anti-corrosion coating chimney anti-corrosion system, anti-corrosion ZS coating overall thickness of 3 mm, service life of more than 20 years. The overall ZS anti-corrosion coating system after acid corrosion can be long-term operation in pH of less than 4 weak acid, high sulfur, high temperature flue gas environment, can resist a variety of concentrated acids (including hydrofluoric acid) and exhaust gas condensate including chloride corrosion, acid gas and condensation completely impermeable, long-term resistance to 50 degrees C, 5% sulfuric acid corrosion. After Zhisheng Weihua anti-corrosion coating test to achieve temperature resistance, chimney anti-corrosion system can adapt to a wide range of temperature changes of 40 degrees C to 120 degrees C, to ensure long-term normal operation at 75 degrees C and below, but also should be able to withstand temperature of 120 degrees C or more each time not less than 5 hours, not less than 50 hours (10 times) high temperature operating conditions, without any damage. ZS-1041 flue gas anti-corrosion coating and ZS-1042 desulfurization special anti-corrosion coating anti-temperature change performance, when the smoke temperature mutation, all anti-corrosion materials should ensure that no damage to maintain normal work. Anti-flue gas washes the Weihua smoke anti-corrosion coating, in the high flow rate area of the flue gas, there should be anti-wear coating and other effective measures to prevent corrosion-resistant materials from being worn. Anti-corrosion materials should have good bonding and covering effect with the inner wall of the chimney, and anti-corrosion materials should have high acidity and resistance to aging, high temperature resistance and long-term flexibility or elasticity.
Coal-fired, gas-fired, heavy-oil-fired coal-fired power plants, coking plants, cement plants, ceramic plants, sulphuric acid plants, smelters, drying plants and other industrial plants, combustion substances in the combustion of acidic gases through the smoke chimney, the content of acidic media in the flue gas and the use of coal or heavy oil sulfur emissions. Burning pipe inner wall, ash platform, high flue gas flow rate, flue reinforced concrete, fire-resistant brick, bulging pearl slab insulation layer, special-shaped reframing ceramic brick, acid-resistant plastic mud, acid-resistant concrete and other materials surface coating ZSAPC Zhisheng ceramic polymer anti-corrosion coating, effectively prevent corrosion of chimney flue, corrosion-resistant years can reach 20 years. In addition, Zhisheng Weihua smoke anti-corrosion coating experts pointed out that the chimney flueway for a long time under the role of flue gas acidic media gradually corroded, over time often caused by the destruction of chimneys, in order to avoid the corrosion of smoke soot acid and alkali, must be in the inner wall of the chimney flue for corrosion protection materials, painting ZSAPC ceramic polymer anti-corrosion coating long-term use of materials in a corrosive environment.
