Reactors widely used in the chemical industry, due to the corrosiveness of the medium, reaction conditions, transportation, use, man-made problems, there will always be such and such enamel layer damage, resulting in unnecessary production s, such as large areas of falling off, it is recommended that we can only return to the factory to re-enamel. The price of enamel kettle is relatively high, and it is not necessary to update the whole equipment when the minor damage occurs. This requires that the appropriate repair method be selected and repaired immediately with JS916.
