The smoke exhaust pipe is a tubular device for exhaust gas and smoke discharge. These flue gases are corrosive, because the flue gas contains SO, when the condensation at low temperature, it is easy to generate sulfuric acid or sulfurous acid, and it is easy to corrode the heating surface of the tail. Therefore, in order to consider comprehensively, the lower limit of boiler exhaust gas temperature is 150, and the minimum exhaust gas temperature can reach 120. The special environment of exhaust gas in the flue determines the difficulty of flue anticorrosion. Therefore, it is necessary to pre-protect the flue before use, or to do flue anti-corrosion protection in time when flue corrosion occurs, which can greatly extend the service life of the flue.
High-temperature anticorrosive coating for smoke exhaust pipesRLHY-9035 chimney flue acid-alkali wear-resistant anti-corrosion coating, high density of coating, can effectively shield the penetration of gas and corrosive liquid, chemical resistance, salt water resistance, salt spray resistance, damp heat resistance, oil resistance, mildew resistance, atmospheric aging resistance, alkali resistance, potassium resistance, brine corrosion, etc., effectively prevent acid and alkali corrosive medium physical reaction and chemical reaction. The coating has good integrity, low shrinkage, high hardness, wear resistance and temperature resistance. Even if it is used under harsh conditions, it can have good durability and weather resistance. It can not only meet the requirements of anti-corrosion in corrosive environments, but also meet the requirements of performance fatigue with alternating performance. Therefore, it can protect the substrate from being damaged and bring long-term benefits to enterprises and construction personnel.
Compared with conventional anticorrosive coatings, RLHY-9035 chimney flue acid-alkali wear-resistant anticorrosive coating performance is more stable, the high-density protective film formed after brushing can effectively isolate the erosion of acid and alkali media, can be used in relatively harsh corrosive environments such as desulfurization systems, pipelines, dust collectors, etc., and has a class of anticorrosive coatings that can achieve a longer protection period than conventional anticorrosive coatings.
