Problems solved by technology

In fact, the grinding and cleaning agents in the prior art, due to their own defects, will corrode and oxidize non-ferrous metals in order to ensure the cleaning process, resulting in non-ferrous metals being corroded in a short period of time, resulting in color difference, affecting the application
Moreover, the cleaning solution needs to be heated during the cleaning process, otherwise the cleaning effect will not be achieved, and the higher temperature will further increase the corrosion of non-ferrous metal materials and increase the processing cost
In addition to the above-mentioned shortcomings, the existing non-ferrous metal grinding and cleaning fluids are also highly polluting, unfriendly to the environment, and easily cause damage to the operator and the surrounding environment

Abstract

The invention discloses a general aqueous cleaning solution for non-ferrous metals; rosin polyoxyethylene ether is served as a main agent; an alcohol ether surfactant and a fatty acid polyoxyethylene ether are served as an active agent for removing dirt; the cane sugar is served as a hard water complexing agent; the pH value is increased by using an organic base; alcohols and de-ionized water areserved as solvents; the general aqueous cleaning solution for non-ferrous metals has low cost, non-toxicity and harmlessness without corrosion and simulation on skin, harm to human bodies and pollution to the environment, has good cleaning corrosion inhibition performance and lasting effectiveness without danger to physical health of operators, and is applicable to cleaning and processing variouskinds of non-ferrous metals and capable of providing stable performance at the moderate temperature; an corrosion-resistant protecting film absorbed tightly is formed on the surface of the workpiece and has better corrosion inhibition effect; and the surface of the cleaned non-ferrous metal workpiece is clean and has no colour difference.

Description

technical field [0001] The invention relates to a cleaning cooling liquid for mechanical processing, in particular to a general-purpose water-based cleaning liquid for nonferrous metals. Background technique [0002] All kinds of non-ferrous metals are widely used in various fields due to their unique properties. Non-ferrous metals, like other materials, need to be machined before use, and applied after they have qualified shape and surface parameters. [0003] Any material, including non-ferrous metals, generally needs to be cleaned after processing in order to meet the needs. For non-ferrous metals, the surface after processing needs to maintain a high degree of smoothness without color difference, and the cleaning fluid is required to be relatively low, which requires the cleaning fluid to be less corrosive. However, in the prior art, since various non-ferrous metals have different oxidation characteristics, they have different oxidation resistance or oxidizability for ...
