Problems solved by technology

[0002] Existing water-based metal cleaning agents, due to various reasons such as their formulations, use phosphorus-containing builders and other additives. Although they have a certain cleaning ability, the phosphorus element will cause eutrophication of the environmental water body. The discharge of waste liquid is strictly restricted, which cannot meet the requirements of the market and environmental protection
And the existing water-based metal cleaning agent, although it has certain anti-rust properties to metal materials, the anti-rust period is relatively short, generally 1-3 days, which cannot meet the requirement of not doing anti-rust treatment for a long time during cleaning between processes
