Problems solved by technology

In addition, most of the existing cleaning agents for metal aluminum materials are solvent-based, phosphorus-containing water-based cleaning agents, etc. The disadvantages of these cleaning agents are that the cleaning effect is not very ideal, and the cleaned metal aluminum materials are prone to black surface layers, which is harmful to the follow-up. Processing brings trouble, especially for the processing of precision components; it is highly corrosive to equipment and increases the cost of equipment; the cleaning time is long, and it takes 10 to 30 minutes to clean

Abstract

The invention provides a cleaning agent for the aluminum material, which comprises silicate, phosphate, a surfactant, a Ph value regulator and deionized water. The weight percentage of every component is that the silicate is 3 to 10 percent; the phosphate is 5 to 10 percent; the surfactant is 5 to 10 percent; the Ph value regulator is 1 to 6 percent and the deionized water occupies the residual percentage. The Ph value of the mixed solution is 11 to 12. The cleaning agent has high effective and easy-to-clean function for the aluminum material, completely cleans the oil spot and rust spot on the surface of the aluminum material, prevents the rust spot from forming on the surface of the aluminum material again, shortens the cleaning time and improves the working efficiency. The cleaning agent is a water soluble cleaning agent, so the waste liquid left after washing is easy to discharge and accords with the environmental requirements. Furthermore, the cleaning agent has low corrosion to the equipment, which effectively reduces the production cost and is safe and reliable in using.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based cleaning agent for metal aluminum materials. Background technique [0002] Metal aluminum materials need to be cleaned before processing, and the amount of ordinary mechanical parts processed by metal aluminum materials and precision components used in other fields is quite large, so the workload of cleaning such metal parts is correspondingly large Large, the amount of cleaning agent required in the cleaning process must also be quite large. With the stringent environmental protection requirements and standards, the discharge control of industrial wastewater is becoming more and more stringent. Therefore, the discharge of a large number of waste cleaning agents has become an important topic for this industry to study. In addition, most of the existing cleaning agents for metal aluminum materials are solvent-based, phosphorus-containing water-based cleaning agents, etc. The disa...
