ANTIBACTERIAL METHOD FOR WATER-SOLUBLE MACHINE OIL

PURPOSE:To efficiently suppress the propagation of bacteria harmful to a human body without adding an antibacterial agent to water-soluble machine oil by arranging a negative electrode composed of metal zinc and an positive electrode composed of a metal of which the potential is higher than that of metal zinc in the water-soluble machine oil to form a Volta battery. CONSTITUTION:Since org. water-soluble machine oil being a non-electrolyte contains org. matter as an effective component, bacteria harmful to a human body are easy to propagate. In order to apply an antibacterial property to this water-soluble machine oil, a negative electrode composed of metal zinc and a positive electrode composed of a metal of which the potential is higher than that of metal zinc are arranged in the water-soluble machine oil respectively to form a Volta battery. Further, the anode and the cathode are arranged in the water-soluble machine oil and the water-soluble machine oil may be subjected to electrolytic treatment by a DC or AC current. Furthermore, silver zeolite may be added to the water-soluble machine oil in a ratio of 0.3-2g/l. By this constitution, the propagation of bacteria harmful to a human body is efficiently suppressed without adding an antibacterial agent to the water-soluble machine oil.
