Abstract

The invention discloses a high-efficiency derusting liquid. The high-efficiency derusting liquid comprises magnesium oxide, dichloromethane, formic acid, dimethylbenzene, ethyl caprylate and the balance of industrial pure water. The high-efficiency derusting liquid has no toxicity, no smell, corrosion resistance and high strength and is prepared orderly by carrying out weighing, proportioning, blending, stirring, dissolution and filling processes on easily available chemical raw materials. The high-efficiency derusting liquid can be widely used for the fields of aviation, petroleum, chemical engineering, hardware, molds, medicines, foods, automobiles and textile and basically saves the problem that a metal product rusts easily.

Description

technical field [0001] The invention relates to a high-efficiency derusting water, which belongs to the technical field of chemical products. Background technique [0002] Although the rust removal liquid currently on the market has the ability to remove rust, it is easy to damage the skin of the human contact area. Long-term contact will cause the residual liquid to damage the body, cause diseases, and pollute the environment. The price is very high. [0003] For overcoming existing above-mentioned defective, the purpose of this invention is to provide a kind of: [0004] 1. Non-toxic and tasteless, no waste discharge. [0005] 2. It has high bonding strength with metal parts, does not peel off, does not fall off, not only maintains the mechanical properties of the original metal parts, but also increases corrosion resistance and wear resistance. [0006] 3. No matter it is the complex surface such as the inner wall of the pipe, deep hole, counterbore, product corner, etc...
