In the Shandong area, less than a week in the summer, usually only one month will deteriorate and smell bad and have to replace the new liquid. Not only does it cause a lot of waste of water, but it also increases the labor intensity of replacing the cutting fluid.

Tests have shown that it can greatly extend the life of the emulsion, the effect of which can be found in the attached table.
