Nanometer screen window for preventing PM2.5 and method for preparing screen window material
The invention discloses a nanometer screen window for preventing PM2.5 and a method for preparing a screen window material. The nanometer screen window (NSW-2.5) is composed of a window frame, carbon non-woven fabrics and a nanometer filtering membrane, wherein the nanometer filtering membrane is made of dispersed nanometer acetate fibers, a plurality of nanopores with the pore diameter being 0.5-1 mum are formed, and the porosity of the nanometer filtering membrane is 85-98 percent. The NSW-2.5 can isolate particles with the aerodynamic diameter larger than 2.5 mum in the air and meanwhile keeps good daylighting and ventilation effects. The NSW-2.5 screen window is detachable and is convenient to wash. Moreover, as the nanometer filtering membrane is made of fiber materials, the NSW-2.5 screen window can be rolled and is convenient to store. The NSW-2.5 screen window belongs to the field of household environmental-protection equipment, has the advantages of being low in cost and easy to dismount and wash, realizes integrated mechanized production, and is more easily accepted by the market.
