摘要
An aqueous solution for diluting a water-soluble metal working fluid, characterized in that it is produced through the electrolysis of water, has a pH of 8 to 13, and comprises active oxygen contained in hydrogen peroxide in a concentration of 1 mg/L or more. The aqueous solution is produced by supplying water to an electrolysis vessel which comprises a cathode comprised of a cathode electricity feeder made from stainless steel plated with nickel or the like or from titanium plated with platinum or the like and an electrode made from a carbonaceous material or a gas diffusion electrode and an anode made from titanium plated with platinum or the like, the cathode and the anode being isolated by a diaphragm and provided opposite to each other, and supplying air or a gas containing oxygen to the surface of the cathode, and then passing an electric current. The mixing of the aqueous solution with a water-soluble metal working fluid provides a fluid coolant which exhibits durable putrefaction preventing effect, without adversely affecting a human body, the environment, the fluid itself, or performance capabilities of the fluid.
