| titleOfInvention | A kind of rust remover replacing hydrochloric acid rust removal |
| abstract | The invention provides a rust remover that replaces hydrochloric acid for rust removal, wherein, the rust remover used for rust removal is made from the following raw materials by weight: 20-30 parts of composite organic acid, 5-10 parts of polymethacrylic acid parts, 6-12 parts of chromic anhydride, 10-20 parts of surfactant, 3-6 parts of sodium gluconate, 1-3 parts of triethanolamine, 1-3 parts of polyacrylamide, 1-3 parts of 1,4-butynediol 2 parts, 0.01-0.1 part of sodium chloride, 0.5-2 parts of functional additives, 70-90 parts of water; the pH of the rust remover is about 6.0, and the density is 0.9-1.2g/cm 3 ; the rust removal of the present invention The rust remover does not use hydrochloric acid, which means that the generation of acid mist is reduced from the source. The rust remover does not use substances that are harmful to the human body and will not pollute the environment. It is an environmentally friendly rust remover; and this rust remover has very good rust removal performance Excellent, the rust removal time is very short, and the rust removal rate is very high, which effectively restores the surface gloss of the metal substrate, and has great application prospects. |
