PLATINUM NANOPARTICLE AQUEOUS SOLUTION AND AIR CLEANER USING THE SAME, HUMIDIFIER, AIR CLEANER WITH HUMIDIFIER, AND POROUS FILTER

摘要

PROBLEM TO BE SOLVED: To provide an air cleaner or the like at a low price, utilizing the high antibacterial property/deodorizing property of platinum nanoparticles.;SOLUTION: A platinum nanoparticle aqueous solution, for which the stock solution of the platinum nanoparticle aqueous solution that contains platinum nanoparticles and is formed by being dissolved in one liter of water is diluted by the water of the volume of any one of 400 times, 800 times and 1,500 times further, is prepared. A porous filter 3 is subjected to impregnation or the like in the diluted platinum nanoparticle aqueous solution beforehand, and then the porous filter 3 that has absorbed the platinum nanoparticle aqueous solution is dried. The porous filter 3 in a sheet shape has many through-holes to be a path of air of several μm, which is bent zigzag in all directions on the inside thereof. The flow of air AA discharged from a suction fan 2 hits a front surface of the filter 3 and passes through the path of each through-hole therein. Inside the path, many platinum nanoparticles having high antibacterial property/deodorizing property are present.;COPYRIGHT: (C)2014,JPO&INPIT
