Problems solved by technology

[0002] At present, most metals are relatively easy to rust. There are many reasons why metals rust, such as storage environment, climate, etc. In addition to these factors, the corrosion resistance of the metal itself is very strong. The big relationship is that when metal is rusted, metal rust removers are used for cleaning, and these metal rust removers basically contain phosphorus and are easy to pollute the environment. Disadvantages of complicated process, long cleaning time and high cleaning cost

Abstract

The invention discloses a non-phosphorus metal cleaner, belonging to the field of cleaners in mechanical industry. The non-phosphorus metal cleaner is composed of the following raw materials in percentage by weight: 20-30% of sodium carbonate, 8-10% of gluconic acid, 6-10% of dodecylbenzene sulfonic acid, 0.5-1.5% of sodium benzoate, 2-3% of peregal, 1-3% of benzotriazole, 2-4% of sodium hydroxide and the balance of water. The non-phosphorus metal cleaner is free of phosphorus and environment-friendly, can be used for cleaning ferrous metals and nonferrous metals in industry, and has the advantages of short cleaning time, favorable cleaning effect, no corrosion on parts, antirust function and low cost.

Description

technical field [0001] The invention relates to the field of mechanical industry cleaning agents, in particular to a phosphorus-free metal cleaning agent. Background technique [0002] At present, most metals are relatively easy to rust. There are many reasons why metals rust, such as storage environment, climate, etc. In addition to these factors, the corrosion resistance of the metal itself is very strong. The big relationship is that when metal is rusted, metal rust removers are used for cleaning, and these metal rust removers basically contain phosphorus and are easy to pollute the environment. The process is complicated, the cleaning time is long, and the cleaning cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings and deficiencies in the prior art and provide a phosphorus-free metal cleaning agent. It does not contain phosphorus and is environmentally friendly. It can clean fer...
