In chemical plants, chimneys are important discharge facilities, but their surfaces are prone to corrosion and damage due to high temperatures, corrosive gases, and moisture for long periods of time. In order to ensure the safe operation of the chemical plant and environmental protection requirements, it is necessary to repair the chimney in time. It can be repaired with KNM22 flue anticorrosive coating.
KNM22 flue anticorrosive coating adopts polymer synthesis technology, which has strong adhesion and weather resistance. It is able to effectively isolate the high temperature and corrosive gases inside the chimney while preventing moisture penetration, thus protecting the chimney from corrosion and damage. In addition, the coating has excellent UV resistance and self-healing properties, which can maintain the integrity and anti-corrosion properties of the coating for a long time. The specific operation steps in the repair of the chimney of the chemical plant are as follows: first, the surface of the chimney needs to be cleaned and pretreated to remove oil, rust and other impurities on the surface. Then, the KNM22 flue anticorrosive coating is stirred evenly and coated according to the construction requirements of the coating to ensure that the coating is uniform and free of bubbles and cracks. In the coating process, it is also necessary to pay attention to controlling the thickness and drying time of the coating to ensure the quality and performance of the coating. Third, the coating can be cured at room temperature. Fourth, check that the coating is free of defects.
In conclusion, the corrosion resistance of the chimney is improved and the service life is extended after the preparation of the KNM22 flue anticorrosive coating coating for the flue.
