High-pressure water abrasive descaling: using the impact of high-pressure water jet and the role of water pry to destroy the scraper rust and coating adhesion to the steel Plate. This method has no dust pollution, does not damage the steel plate, greatly improves the rust-removing efficiency, and the rust-removing quality is Good. But after the rust of the steel plate easy to return to rust, must be coated with a special wet rust coating, The general can paint coating has a greater impact.
2. Apply anti-oxidant paint: apply mineral oil on the scraper surface, paint or burn enamel, spray and so On. In the steel surface by electroplating, hot plating and other methods of plating on a layer of rust-resistant metal, such as zinc, tin, chromium, nickel and so On. These metal surfaces can form a dense layer of oxide film, which prevents iron products from contact with water, air and other materials and Rust.
3. Chemical Descaling: the use of acid and metal oxides chemical reaction, so as to remove the scraper metal surface corrosion products, that is commonly said pickling descaling, This method is only suitable for operation in the Workshop.
