Metal cleaning agent

Abstract

The invention belongs to the technical field of metal cleaning agents and particularly relates to a metal cleaning agent. The metal cleaning agent comprises, by weight, 60-80% of sodium orthosilicate, 12-30% of sodium carbonate, 4-10% of triethanolamine, 3-8% of washing assistants, 1-2.5% of fatty alcohol-polyoxyethylene ether and 0.5-1% of defoaming agents. The metal cleaning agent has the good performances of wetting, permeation, emulsification, dispersing and solubilizing, and is good in cleaning effect, free of pollution, short in cleaning time and high in detergency.

Description

technical field [0001] The invention belongs to the technical field of metal cleaning agents, and in particular relates to a metal cleaning agent. Background technique [0002] Metal cleaning is one of the indispensable processes in mechanical processing, because in different metal processing processes, various types of dirt may adhere to the surface of metal parts and equipment. Only by fully cleaning these dirt can the next process be guaranteed. The smooth progress and the processing quality of the product. [0003] At present, chemical pickling (mainly removing metal oxides), chemical alkali cleaning (removing animal and vegetable oils), organic solvent cleaning (relying on solvents to dissolve dirt) and water-based cleaning are often used for different types of dirt. However, the above-mentioned first three cleaning agents all have different defects. For example, solvent cleaning will directly pollute the air and destroy the ozone layer of the atmosphere due to the vol...

Problems solved by technology

However, the above-mentioned first three cleaning agents all have different defects. For example, solvent cleaning will directly pollute the air and destroy the ozone layer of the atmosphere due to the volatilization of organic solvents. It is flammable, explosive, and unsafe; chemical cleaning also pollutes and corrodes the equipment. , unsafe for workers, and the scope of use is narrow; therefore, it is necessary to develop a cleaning agent with low cleaning cost, safe use, and no pollution to the environment, which has become the main development direction of the metal cleaning industry
