Descaling, rust inhibitor and rust removal method using the same

摘要

Disclosed metal products one liquid rust or immersion in (rust removal, rust), and to completely remove the rust by simply applying a rust removing anti-corrosion agent to the rust on the surface, the metal to remove rust to post-processing such as cleaning unnecessary. Also, it is not necessary to wash the metal products taken out from the liquid rust up-rust agent, and only indoors, exerting the anticorrosive effect long-term outdoor both wiping the natural drying or liquid. Furthermore, the provision of two of rust inhibitor and rust way was to have the functions of the rust up function and anti-rust function in one solution of rust removing anti-corrosion agent. If it was about the weight of 1Kg [MEANS FOR SOLVING PROBLEMS] descaling, rust inhibitors whole, the orthophosphoric acid is about 50g~ about 600g, the DL- malic acid is the weight of the water about 0.2g~ about 2g, the remainder I will be the weight ratio was. After removing the rust in rust removal, rust inhibitor, by wiping or air-drying the solution, to exhibit rust preventive effects phosphate film is formed on the surface of the metal.
