Description

technical field [0001] The invention relates to an anti-corrosion conductive coating composition, which is particularly suitable for anti-corrosion conductive coatings for corrosion protection of corona discharge type flue gas purification equipment. Background technique [0002] With the rapid development of the economy, environmental problems have become increasingly prominent, the types of environmental pollutants controlled have been increasing, and the emission standards have been continuously improved. Flue gas purification equipment such as ultra-low temperature electrostatic precipitator and wet electrostatic precipitator, flue gas desulfurization, and denitrification have been or will soon be popularized and applied in thermal power plants. Since the flue gas contains H 2 O, O 2 , SO 2 , NOx, HCl and other components, when the flue gas purification process reduces the temperature of the flue gas below its dew point, the flue gas will condense on the surface of th...
