PROBLEM TO BE SOLVED: To achieve a low-priced cleaning apparatus utilizing the high antibacterial properties and high deodorant properties of platinum nanoparticles.SOLUTION: The drip of a platinum aqueous solution with high antibacterial properties and deodorant properties obtained by diluting the undiluted solution of a platinum aqueous solution in which platinum nanoparticles are dissolved with water of 1L with water of a volume in any magnification of 400 times, 800 times and 1,500 times is stuck to the surface of ceramic balls 3. The high antibacterial properties and deodorant properties of the platinum nanoparticles dissolved into the platinum aqueous solution are utilized. The water soluble cutting liquid as the cooling water of a cutting machine septic in a storage tank 1 successively passes through a nonwoven filter 6 and a porous filter 5, is filtered, and is thereafter allowed to flow into the ceramic ball layer 3. The platinum nanoparticles dissolved into the platinum aqueous solution stuck in a drip shape to the respective surfaces of many ceramic balls 4 shut off an odor source and kill bacteria or the like by the exhibition of the antibacterial performance and deodorant performance thereof. The aqueous cutting liquid returned under circulation is cleaned to the respective steps. |
