Description
Technical field
The present invention relates to a kind of cleaning agent, more particularly to a kind of environment-friendly type skimmed milk handled for metal material surface,
The invention further relates to the preparation method of the skimmed milk.
Background technology
Metal works are during manufacture, transport, storage and use, and because machining and antirust etc. need, its surface is applied
There is grease.These greases are the compositions based on mineral grease and vegetable fat, and added with various organic or inorganic additives
Composition is formed.Therefore in metal material surface processing, degreasing is important technical process, and the degreasing degree of metal surface will be straight
Connect the subsequent treatment quality for having influence on workpiece.
Surface of workpiece lubricant component is more complicated, and a class is the saponified oil based on fatty glyceride, can be passed through
Removed with the saponification of alkali；Another kind of is mineral oil (non-soap carburetion), can be removed by emulsification.
At present, the auxiliary agent of most water-base metal degreasing agents is still based on phosphate, because phosphate is in degreasing agent
In existing chelation, have decontamination again, and have good washing and the low feature of use cost.But as people get over
Carry out more attaching importance to environmental protection, more and more stricter is required to the limitation that P elements are discharged, inexorable trend is turned into using agent of non-phosphate degreasing.
In addition, metal degreasing agent on the market is largely fluid product at present, active constituent content is limited, to packaging,
Storage, transport add cost.
