| titleOfInvention | A kind of environment-protective process replacing hydrochloride derusting |
| abstract | The present invention provides a kind of environment-protective process for replacing hydrochloride derusting, wherein the rust remover for derusting is prepared from the following raw materials in parts by weight: 20~30 parts of composite organic acid, 5~10 parts of polymethylacrylic acid, 6~12 parts of chromic anhydride, 10~20 parts of surfactant, 3~6 parts of sodium gluconate, 1~3 part of triethanolamine, 1~3 part of polyacrylamide, 1,1~2 part of 4- butynediols, 0.01~0.1 part of sodium chloride, 0.5~2 part of function additive, 70~90 parts of water；The pH of the rust remover is 6.0 or so, and density is 0.9~1.2g/cm 3 ；Rust remover of the present invention does not use hydrochloric acid, i.e., reduces acid mist from source and generate, the substance being harmful to the human body is not used in rust remover, will not generate pollution to environment, be a kind of Environment-friendlyrust rust inhibitor；And this rust remover derusts, and performance is very excellent, and the derusting time is very short, while derusting rate is very high, effectively restores metal base surface gloss, great application prospect. |
