This product is a transparent or light yellow liquid, which is synthesized by strong oxidizing agents, corrosion inhibitors, brighteners, ash inhibitors, high-efficiency deoiling additives, chelating additives, etc.; this product is acidic, through various inorganic acids and oxidants. Weak etch, effectively dissolve, loosen natural oxide film, oil stain, carbon deposit, has the dual functions of descaling and surface oil staining. The treated profile can be directly oxidized, simplifying the pre-oxidation treatment process; Corrosion agents and surfactants overcome the disadvantages of incompletely solidified aluminum materials (such as refining, insufficient quenching air volume, severe segregation of crystals), sanding, bright crystals, etc., and have the effect of rapid degreasing without heating one step in place. It overcomes the drawbacks of traditional degreasing and heating, reduces costs, improves work efficiency, and reduces air pollution in the workshop.
