When the form of screen window carries out outdoor haze stop, window screening mesh could effectively intercept haze when only having less than 2.5 microns, and this does not lose
It is a kind of effective method that haze protection is carried out with physical method, this method is used on some haze Protection Products
Cross.But, it is known that when carrying out haze protection indoors, anti-haze is the first purpose, it is often more important that to carry out interior has
The discharge of evil gas and the supplement of oxygen.Because the injury of indoor harmful gas and anoxic to human body is no less than haze.Therefore,
During using screen window as anti-haze instrument, screen window will be responsible for the double action that anti-haze and indoor harmful gas are exchanged, and be previously mentioned
The anti-haze method of physics, as long as window screening mesh is sufficiently small, anti-haze effect is likely to be breached to a certain degree, but when the aperture of window screening mesh
During very little, Air permenbility will have a greatly reduced quality, and people often feel very vexed indoors, or even dizzy, lose the true of anti-haze screen window
Meaning.

Connect and be coated on common window screening, its small and weak electric field force is difficult to flutter completely and catches by the haze particle of window screening, and the macropore of window screening
Hole also is difficult to the bulky grain thing in stop air, does not reach the effect of anti-haze.If by can be with the hole of the gauze of anion releasing
Footpath diminishes, and changes pass, makes the electric field force of anion that maximum is reached in effective scope, and round using regular shape
The vortex phenomenon that hole is formed to the dust flowed in air, barrier effect will strengthen a lot, can just reach good anti-haze dust-proof
Effect；The micropore on the function film of anion releasing is maximized simultaneously, is carried out effectively and the exchange of the indoor gas of abundance.

In order to preferably verify using effect of the invention, explanation more further is made of experimental data below：
Adsorbed using anion or repel the fine particulates in air, will can yet be regarded as a good anti-haze method.But
It is that the Coulomb force between electric charge and distance square are inversely proportional, i.e., distance is bigger, and active force is smaller, how effectively apart from model
Make the active force of electric charge most effective (anti-haze effect) in enclosing, and open pore size energy is maximum (Air permenbility), this will be that anionic film is opened
The theory and implementation basis of hole pore size.
According to Coulomb's law：K=9.0 × 109Nm2/C2,
With haze 500ug/m in air3It is basis, per mm3Haze is 0.5x10-7ug；Folder between two electric charges
Angle is assumed to be 0 °, i.e.,The powered e=1.6x10 of elementary charge-19Coulomb, with every mm3Anionic film discharges 10 negative electrical charges
As a example by.Result of calculation is obtained：R=169um, i.e., when the maximum opening diameter of the anionic film 4 of micropore window screening film is 338um, i.e.,
500ug/m can effectively be prevented3Air in haze.
In addition, according to aerodynamic principle, when the aperture of micropore 11 is less than 6mm, when percent opening is less than 40%, wind passes through
During aperture, stronger vortex phenomenon will be produced during sudden contraction, produce impact loss and multiple jet losses by mixture, aperture is got over
Small, hole density is smaller, and this loss is bigger.Therefore, the appropriate percent opening of control anionic film 4, it will major part stops room
Outer dust gets in, and this is also that aperture eddy current effect is applied to the most solid theoretical foundation of anti-haze micropore window screening film.
Calculated according to more than, when the open pore size of anionic film 4 is less than 338um, more than 95% anti-haze effect can be reached
Really.And to the exchange of indoor and outdoor gas, because the particle diameter of gas is general in 0.3~0.4nm, less than pm2.5 particulate matters 1000~
10000 times, and gas follow forever principle of the high concentration to low concentration free diffusing, indoor formaldehyde, carbon dioxide etc. be harmful to
Gas can straightway row to outdoor, and the oxygen of outdoor can endlessly get in, therefore, indoor and outdoor gas can
Efficiently exchanged, reached as high as every square metre of 33.75m per minute3。
To be anti-haze micropore window screening film production so electron adsorption technology is effectively combined with aperture vortex windage technology
Strong theoretical foundation, can reach good anti-haze effect, while can also reach the exchange interaction of effective indoor and outdoor gas.
Rule of thumb formula makes the ventilation volume of anionic film 4 disclosure satisfy that the demand in a certain size room, needed for room
The area of anionic film is calculated by following formula：The area of S anionic films for needed in formula, unit is m2It is (flat
Square rice)；V is room volume, and unit is m3(cubic meter)；Q is the Air permenbility of anionic film, and unit is L/hm2(Sheng/ little Shi ﹒
Square metre)；T is room time of exchanging gas, and unit is h (hour).
The Q is calculated by following formula：Q=0.9752 × 10-3×r2× ρ, r is the pore radius of anionic film in formula,
Unit is μm (micron)；ρ is the pore density of anionic film, and unit is individual/cm2(individual/square centimeter).Gas is by micropore
The characteristics of motion is relevant with Michel Knuysen coefficient, Michel Knuysen COEFFICIENT K n=λ/R, and wherein R is pore radius.When Kn≤0.001, gas
Gym suit is from molecular motion rule in hole；When Kn >=10, gas flows in hole and is described by hydrodynamics, obeys
Poiseuille equations.Air molecule diameter about 0.3nm, at normal atmospheric pressure its mean free path λ be about 93nm.With air
As a example by motion in the micropore of the anionic film that aperture is 200 μm, its Kn=0.093/25=0.01478, therefore air fortune
Move between molecular motion and Classical Fluid Mechanics.To Incompressible gas, pushed away according to Bernoulli equation and continuity equation
Lead, flow be proportional to micropore sectional area, i.e. pore radius square.
People's breathing per minute 16 times, average suction about 0.55L air every time, then everyone per hour inhaled air volume be
528L.According to 100cm2, the aperture of micropore 11 is 300 μm, 400/cm of pore density2Anionic film 4 take a breath, then often
Hour gas exchange can meet the requirement of 3 personal breathing fresh airs up to 1877L.It is 20m for area2, floor height is 3m
Room, its volume V be 60m3, when the micropore size of anionic film 4 is 300 μm, pore density is 400/cm2When, by above-mentioned
The anionic film area that formula can be calculated required for complete space air is changed within the t times is 0.68/t.I.e. for 60m3
Room, if 1 hour complete ventilation, area be 0.68m2, micropore size is 300 μm, and pore density is 400/cm2It is negative
Ionic membrane 4 just can meet requirement.

As shown in table 2, when the micropore size on anionic film is different, the collection effect of the aerosol particle of micropore window screening film
The relation table of aerosol particle diameter in rate and air.
As a example by aperture by micropore 11 is 300 μm of anionic film 4, it is flutterred and catches collection particle efficiency and have with particle size
Close, to particle diameter for 10nm to 300nm particle collection efficiency is only 20%, to less than 10nm particles, the smaller collection efficiency of particle diameter is got over
Height, as particle as low as 1nm, collection efficiency is up to 90%.To more than 300nm particles, particle diameter is bigger, and collection efficiency is higher, works as grain
Sub greatly to 1 micron, collection efficiency is minimum up to 70%, and when particle is greatly to 2.5 microns, collection efficiency is minimum up to 90%.With the phase of table 1
With reference to more than 90% depositing dust, flying dust, pollen can be stopped outside by anionic film 4 in outdoor air；More than 70% coal ash,
Cement dust, vehicle exhaust, gas-fired, flue dust, bacterium, carbon ash, metal dusting and cigarette can be stopped outside by anionic film 4；And
The micropore 11 of the indoor permeable anionic film 4 of the virus overwhelming majority flows to outdoor with air flow by interior；It is thin for interior
Bacterium, kitchen fume, tobacco smoke and radon and its daughter, the micropore 11 of the permeable anionic film 4 of a part reach outdoor, other portions
Divide and the anion discharged by the surface of anionic film 4 and the hole wall of micropore 11 are flutterred and caught.
This is because, when outdoor PM2.5 concentration is higher, that is, contaminant particles concentration is higher, due to interparticle
Free collision movement, outdoor air pressure is higher with respect to room pressure；The free equilibrium principle of concentration is followed, when outdoor pollutant is by anti-
When haze micropore window screening film flow direction is indoor, vortex phenomenon is formed on the micropore 11 of anionic film 4, it is micro- that most of pollutant is refused
Outside the window screening film of hole, only very small part contaminant particle can by micropore 11, but when they by when again by anionic film 4
The anion for being discharged stops or adsorbs, here it is the anti-haze mechanism of micropore window screening film；And for indoor pollutant, great Jia Zhi
The major part such as road, indoor pollutant formaldehyde, carbon dioxide, nitrogen, ammonia, radon and its daughter exists in a gaseous form,
About in 0.3~0.4nm, relatively outdoor pollutant particle diameter differs 100~10000 times to their particle size range, and gas is forever
Principle of the high concentration to low concentration free diffusing far is followed, so they are easy to by the row of micropore 11 to outdoor, and outdoor
Oxygen also can diffuse to interior by micropore 11.Therefore, micropore window screening film possesses the effect of anti-haze ventilation completely.
