What are the countermeasures for the corrosion of gas holder?

What are the countermeasures for the corrosion of gas holder? Let's follow the installation of the gas cabinet.
From the perspective of molecular structure, the original coating has strong air and water permeability, and it is dry at room temperature during construction, and the solvent is slowly volatilized. At this time, dust and other impurities in the environment are easy to mix, resulting in more pinholes in the coating. In addition, the conventional chlorosulfonated polyethylene coating has poor adhesion, strength and water resistance, and is easy to peel off and discolor seriously. Therefore, improving the service life of the protective materials, preventing the deterioration of the water quality of the gas holder and extending the service life of the water quality are the main ways to improve the service life of the gas holder.
Protection of anti-corrosion materials for gas holder installation
(l) The protection of the outer wall of the gas cabinet requires not only good water resistance and corrosion resistance of the protective material, but also high adhesion, surface strength and hardness of the paint film, especially good aging resistance of the protective material. From the perspective of corrosion resistance, conventional oily materials are not good at aging resistance, and are not resistant to acid, alkali and solvent corrosion. The use of chlorosulfonated polyethylene coating can solve the problems of aging resistance, but the strength, adhesion and decoration of the coating have not been solved. Through the screening of protective coatings for gas holders in China, EPH type special coating for high weather resistance protection has light retention, aging resistance, etc., especially chlorosulfonated polyethylene coating with general corrosion resistance. The main ingredients include silicone modified epoxy resin, polyamino vegetable oleic acid synthesis, chlorosulfonated polyethylene resin and paint making additives.
