Problems solved by technology

Its main disadvantages are as follows: ① Poor biodegradation (most commercially available products BOD / COD<0.3, not easy to carry out biochemical treatment, pollute the environment); ② Poor resistance to hard water (diluent is prone to solid crystallization, blocking the high-pressure chamber, and white on the workpiece. Residue); ③Formula raw materials generally contain inorganic alkali, sodium tripolyphosphate and other substances, which are harmful to the environment and human body

Abstract

The invention discloses a high-performance and environment-friendly water-based cleaning agent, which comprises macromolecular carboxylic acid, organic amine, alcohol, a surfactant, a hard water softening agent, a corrosion inhibitor, other additives and pure water. The cleaning agent is good in biodegradability, good in hard water resistance, applicable to high-pressure cleaning, and safe to people and environment, and can realize short-term rust prevention.

Description

technical field [0001] The invention relates to a water-soluble cleaning agent used in metal processing. Background technique [0002] In metal processing, shipbuilding, construction, chemical and other industrial production operations, whether it is the processing and assembly of parts, or process cleaning, heat treatment, and product sealing, packaging and unsealing, the metal surface must be cleaned. Commonly used metal cleaning agents are divided into solvent-based, semi-solvent-based and water-based. Because the water-based metal cleaning agent is easy to clean, less polluting, and cheap, it highlights the application advantages and is more welcomed and favored by users. There are also some prominent drawbacks in the current commercially available water-based cleaning agents, which are in urgent need of improvement and enhancement. Its main disadvantages are as follows: ① Poor biodegradation (most commercially available products BOD / COD<0.3, not easy to carry out b...
