Metal Processing] Selection of hardener types for metalworking fluids

Metal cutting fluid is an indispensable product in the metal cutting and processing industry, which plays a good role in metal processing, such as cooling, lubrication, cleaning and rust prevention, and can effectively extend the service life of cutting tools and reduce production costs. Water-based cutting fluid compared with oil-based, has more excellent cooling performance and low cost, green environmental protection.
Currently on the market water-based cutting fluid customers, most of the use of tap water or groundwater containing more minerals, coupled with the Kingsford processing site constantly precipitated free calcium and magnesium ions, easy to emulsifiers in the system, oleic acid and other additives to form insoluble soaps, thereby affecting the life. Therefore, in the cutting fluid system, according to the different water quality of the region, add the appropriate anti-hard water agent is not a choice.
