Micropore window screening membrane technology index after processing is as follows:
In order to better verify result of use of the present invention, do the explanation of a nearlyer step below by experimental data:
Utilize anion to adsorb or repel the fine particulates in air, a good anti-haze method of can yet be regarded as.But, square being inversely proportional to of Coulomb force between electric charge and distance, namely distance is larger, active force is less, in effective distance range, how to make the active force of electric charge the most effectively (anti-haze effect), and open pore size energy maximum (Air permenbility), this will be theory and the implementation basis of anionic film open pore size size.
According to Coulomb's law: k=9.0 × 10 9nm 2/ C 2,
With haze 500ug/m in air 3for basis, every mm 3haze is 0.5x10 -7ug; Angle between two point charges is assumed to be 0 °, namely the charged e=1.6x10 of elementary charge -19coulomb, with every mm 3it is example that anionic film 4 discharges 10 negative electrical charges.Result of calculation obtains: r=169um, namely when the maximum opening diameter of the anionic film 4 of micropore window screening film is 338um, effectively can prevent 500ug/m 3air in haze.
In addition, according to aerodynamic principle, when small aperture is less than 6mm, when percent opening is less than 40%, wind, when small holes, will produce stronger vortex phenomenon, produces impact loss and multiple jet losses by mixture in sudden contraction process, aperture is less, and hole density is less, and this loss is larger.Therefore, control the suitable percent opening of anionic film 4, major part will stop outdoor dust and enter indoor, this is also that aperture eddy current effect is applied to the most solid theoretical foundation of anti-haze micropore window screening film.
According to above calculating, when anionic film 4 open pore size is less than 338um, the anti-haze effect of more than 95% can be reached.And the exchange to indoor and outdoor gas, because the particle diameter of gas is generally at 0.3 ~ 0.4nm, be less than pm2.5 particle 1000 ~ 10000 times, and gas follows the principle of high concentration to low concentration free diffusing forever, the pernicious gas such as indoor formaldehyde, carbon dioxide can be straightway discharged to outdoor, and the oxygen of outdoor can enter indoor endlessly, therefore, indoor and outdoor gas can exchange efficiently, reaches as high as every square metre of 33.75m per minute 3.
So by the combination of electron adsorption technology and aperture eddy current windage technology effective, by being the strong theoretical foundation of anti-haze micropore window screening film production, good anti-haze effect can being reached, also can reach the exchange interaction of effective indoor and outdoor gas simultaneously.
Rule of thumb formula enables the ventilation volume of anionic film 4 meet the demand in a certain size room, and the area of anionic film 4 needed for room is by following formulae discovery: in formula, S is the area of required anionic film, and unit is m 2(square metre); V is room volume, and unit is m 3(cubic meter); Q is the Air permenbility of anionic film, and unit is L/hm 2(l/h square metre); T is room time of exchanging gas, and unit is h (hour).
Described Q is by following formulae discovery: Q=0.9752 × 10 -3× r 2× ρ, in formula, r is the pore radius of anionic film, and unit is μm (micron); ρ is the pore density of anionic film, and unit is individual/cm 2(individual/square centimeter).Gas is relevant with Michel Knuysen coefficient by the characteristics of motion of micropore, and Michel Knuysen COEFFICIENT K n=λ/R, wherein R is pore radius.When Kn≤0.001, gas in hole gym suit from molecular motion rule; When Kn >=10, gas flows and to be described by hydrodynamics in hole, obeys Poiseuille equation.Air molecule diameter is about 0.3nm, and its mean free path λ is about 93nm at normal atmospheric pressure.For the motion of air in the micropore that aperture is the anionic film of 200 μm, its Kn=0.093/25=0.01478, therefore air movement is between molecular motion and Classical Fluid Mechanics.To Incompressible gas, derive according to Bernoulli equation and continuity equation, flow is proportional to micropore sectional area, namely pore radius square.
People's breathing per minute 16 times, on average sucks about 0.55L air at every turn, then everyone suction air capacity per hour is 528L.According to 100cm 2, the aperture of micropore 11 is 300 μm, pore density 400/cm 2anionic film 4 take a breath, then gas exchange per hour can reach 1877L, can meet the requirement of 3 personal breathing fresh airs.Be 20m for area 2, floor height is the room of 3m, and its volume V is 60m 3, when the micropore size of anionic film 4 is 300 μm, pore density is 400/cm 2time, can the anionic film area changed within the t time required for complete space air be 0.68/t by above-mentioned formulae discovery.Namely for 60m 3room, if 1 hour completes ventilation, then area is 0.68m 2, micropore size is 300 μm, and pore density is 400/cm 2anionic film 4 just can meet the demands.

As shown in table 2, when the micropore size on anionic film is different, the relation table of aerosol particle diameter in the collection efficiency of the aerosol particle of micropore window screening film and air.
For the anionic film 4 that the aperture of micropore 11 is 300 μm, it is flutterred and catches that to collect particle efficiency relevant with particle size, be that 10nm to 300nm particle collection efficiency is only 20% to particle diameter, to being less than 10nm particle, the less collection efficiency of particle diameter is higher, when particle is little of 1nm, collection efficiency is up to 60%.To more than 300nm particle, the larger collection efficiency of particle diameter is higher, and when particle greatly to 1 micron, collection efficiency is minimum reaches 50%, and during particle greatly to 2.5 micron, collection efficiency is minimum reaches 80%.Depositing dust, flying dust, the pollen of more than 90% combines with table 1, outside in outdoor air, can be blocked in by anionic film 4; Outside the coal ash of more than 70%, cement dust, vehicle exhaust, gas-fired, flue dust, bacterium, carbon ash, metal dusting and cigarette can be blocked in by anionic film 4; And the micropore 11 that the indoor viral overwhelming majority can pass through anionic film 4 flows to outdoor with air flowing by indoor; For the bacterium of indoor, kitchen fume, tobacco smoke and Radon and its descendants, the micropore 11 that a part can pass through anionic film 4 arrives outdoor, other parts by the anion that discharges by anionic film 4 surface and micropore 11 hole wall flutter and catch.
This is because, when outdoor PM2.5 concentration is higher, namely contaminant particles concentration is higher, due to interparticle free collision movement, outdoor air pressure is higher relative to room pressure; Follow the free equilibrium principle of concentration, when outdoor pollutant flows to indoor by anti-haze micropore window screening film, the micropore 11 of anionic film 4 forms vortex phenomenon, major part pollutant is by outside the micropore window screening film refused, only has very little a part of contaminant particle by micropore 11, but when they by time again the anion that discharges by anionic film 4 stop or absorption, the anti-haze mechanism of Here it is micropore window screening film; And for indoor pollutant, as everybody knows, the major parts such as indoor pollutant such as formaldehyde, carbon dioxide, nitrogen, ammonia, Radon and its descendants exist all in a gaseous form, their particle size range is greatly about 0.3 ~ 0.4nm, relatively outdoor pollutant particle diameter difference 100 ~ 10000 times, and gas follows the principle of high concentration to low concentration free diffusing forever, thus they easily via micropore 11 discharged to outdoor, and the oxygen of outdoor also can diffuse to indoor by micropore 11.Therefore, micropore window screening film possesses the effect of anti-haze ventilation completely.
The above embodiment is only that protection scope of the present invention is not limited thereto in order to absolutely prove the preferred embodiment that the present invention lifts.The equivalent alternative or conversion that those skilled in the art do on basis of the present invention, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
