Embodiment 1

[0035] The present embodiment relates to a kind of anti-PM2.5 nano screen window (NSW-2.5); figure 1 As shown, the anti-PM2.5 nano-screen window includes a window frame 14 and a nano-screen material fixed on the window frame 14, and the nano-screen material includes a nanofiltration membrane 15 and a film carrier 17, and the nanofiltration membrane 15 is made of dispersed The short filaments of nano-acetate fibers are solidified and glued to the surface of the film carrier 17 (carbon-clamped non-woven fabric).

[0036] In this embodiment, the nano-screen window also includes detachable window strips 13 arranged around the window frame 14, the window strips 13 are provided with several circular grooves 16, and the window frame 14 is provided with several The convex groove 20 that matches the circular groove 16.

[0037]When assembling, the nano-screen window material prepared by the present embodiment is placed between the window frame 14 and the window bar 13, and a circular ...

Embodiment 2

[0053] In this embodiment, the window frame 14 , the nanofiltration membrane 15 , the membrane carrier 17 and the installation methods are the same as those in Embodiment 1, and will not be repeated here. The difference is that a slight improvement is made on the basis of the process in Example 1.

[0054] In order to strengthen the bonding degree of the carbon interlaced non-woven fabric, the strong curing glue and the nano-acetate fiber, the outer surfaces of the first transition roller, the high-pressure roller, the vacuum roller, the hot compaction roller and the second transition roller are all made of ceramic materials, The thermal conductivity of the ceramic material is 20-30W / M.K; the withstand voltage is 10KV; the temperature resistance is 1000 degrees. And the outer surface temperature of the first transition roller, high pressure roller, vacuum roller, hot compaction roller and second transition roller is controlled at 300° C. by electric heating (external heating d...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and relates to air purification products, in particular to a purification equipment capable of intercepting atmospheric particles and even PM2.5, and in particular to a PM2.5 anti-PM2.5 nano screen window (NSW-2.5) and a screen window The method of preparation of the material. Background technique [0002] In recent years, with the continuous development of industrial technology, the air pollution has become more and more serious, and the air quality has continued to decline, seriously affecting people's normal life, especially the more frequent smog weather. The chief culprit of the haze weather is the continuous increase of particulate matter in the atmosphere. [0003] PM, the English full name is Particulate Matter, which is particulate matter. PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 μm in the atmosphere, also known as particulate matter...
