负离子窗纱膜打孔方法及微孔窗纱膜 The method for perforating screens anion membrane and porous membrane screens

技术领域 FIELD

[0001] 本发明涉及膜加工技术领域,特别指一种负离子窗纱膜打孔方法及微孔窗纱膜。 [0001] The present invention relates to the field of film processing technology, and particularly refers to a method for perforating a film screens and screens microporous membrane anion.

背景技术 Background technique

[0002] 众所周知,PM2.5是粒径在2.5微米以下的空气污染颗粒物,以筛分原理,当我们以纱窗的形式进行室外雾霾阻挡时,窗纱网孔只有小于2.5微米时才能有效阻隔雾霾,这不失为以物理方法进行雾霾防护的一种行之有效的方法,这种方法在一些雾霾防护产品上使用过。 When the mist can effectively block [0002] is well known, PM2.5 air pollution particles having a particle size of 2.5 micrometers or less, sieving principle, when we outdoor haze of the barrier in the form of screens, window screening holes only less than 2.5 microns haze, which may well be an effective method for haze physical protection method which used in some haze protection products. 但是,我们知道,在室内进行雾霾防护时,防霾只是目的之一,更重要的是要进行室内有害气体的排放和氧气的补充。 However, we know that, when smog protection indoors, anti-haze just one purpose, but it is important to supplement the indoor oxygen and emission of harmful gases. 因为,室内有害气体和缺氧对人体的伤害不亚于雾霾。 Because, indoor harmful gases and lack of oxygen to the body hurt as much as haze. 因此, 以纱窗作为防霾工具时,纱窗将担负着防霾和室内有害气体交换的双重作用,以前面提到的物理防霾方法,只要窗纱网孔足够小,防霾效果可能达到一定程度,但当窗纱网孔的孔径很小时,透气量将大打折扣,人们在室内往往感到很闷,甚至头晕,失去了防霾纱窗的真实意义。 Therefore, as an anti-haze tool to screens, the screens will have the dual effect of harmful anti-haze and gas exchange chamber, preventing physical haze of the aforementioned methods, as long as the hole is small enough window screening, anti-haze effect may to a certain extent, but when the aperture hole is small window screening, ventilation capacity will be greatly reduced, people tend to feel stuffy in the room, and even dizziness, loss of the true meaning of the anti-haze screens.

[0003] 而大家都知道,空气中烟尘、粉尘、飘尘等带正电荷的颗粒物很容易吸附空气中的负离子,这些负离子使得这些尘粒凝并,成为大粒子沉降下来,从而净化了空气,尤其对粒径小至0.01微米的微粒和难以去除的飘尘凝并效果更明显。 [0003] and we all know, the air smoke, dust, fly ash and other positively charged particles is easily absorbed in the air ions, these ions such that the dust coagulation, became large particles settle, thereby purifying the air, in particular of small particle size 0.01 micron particles and difficult to remove fly ash and more effective coagulation. 不仅如此,负离子也有很好的拟菌作用,它的抑菌机理在于负离子与细菌结合后,使细菌产生结构的改变或能量的转移, 导致细菌死亡。 Moreover, the proposed negative bacteria also have a good effect, its antibacterial mechanism is that the anion binding to bacteria, the bacteria produce changes in the structure or energy transfer, leading to bacterial death. 负离子也能有效去除空气中的多种有害物质,如一些有害的化学物质和挥发性有机化合物VOC等。 Anion can effectively remove harmful substances in the air, such as harmful chemicals and other volatile organic compounds VOC. 因此,负离子消除室内局部雾霾的作用是不可质疑的,这是由于空气中微小粒子基本上都带有正电荷或负电荷,粒径越小,带电性越强,人工合成的负离子粉所释放的负电荷在有效的范围内正好可以吸附或排斥空气中的带电粒子,从而达到降低雾霾的作用;但是,负离子粉所释放的负离子的带电量是有限的,如果将其作为防霾屏障,直接涂布在普通窗纱上,其弱小的电场力很难完全扑捉通过窗纱的雾霾颗粒,而窗纱的大孔洞也很难阻挡空气中的大颗粒物,达不到防霾的效果。 Accordingly, negative ions eliminate local interior haze effect is not questioned, because substantially all the fine particles in the air with a positive or negative charge, the smaller the particle size, the stronger the chargeability, synthetic Anion powder released the negative charge can just adsorbed within the effective range or exclusion of air charged particles, which can reduce haze effects; however, anion powder released anion charge amount is limited, if it is as an anti-haze barrier, directly coated on ordinary screens, its weak electric field force is difficult to completely capture the haze particles pass through the screens, the screens are also very difficult to stop the large pores larger particles in the air, reach the haze prevention effect. 如果将可以释放负离子的纱网的孔径变小,而且改变孔型,使负离子的电场力在有效的范围内达到最大,并且利用规则形圆型孔对空气中流动的尘埃形成的涡流现象,阻挡作用将增强很多,就能达到很好的防霾防尘效果;同时使释放负离子的功能薄膜上的微孔最大化,进行有效而充足的室内气体交换。 If the pore size of gauze can release negative ions becomes small, and change the pass, the electric field strength reaches a maximum negative ions within the effective range, and irregularly-shaped eddy current phenomenon of dust-sized hole formed in the air flowing in the barrier the reinforcing effect of many, can achieve good anti-haze proof effect; micropores while maximizing the functional film on the release of negative ions, effective and adequate gas exchange chamber. 才能有效解决目前防霾窗纱防霾效果好而透气量不足或透气量充足而防霾效果很差的二者不能兼得的实际问题。 In order to effectively solve practical problems currently good anti-haze screens anti-haze effects and lack of adequate air permeability or air permeability and anti-poor haze effect of the two can not have both.

[0004] 针对上述问题,如何实现既能防霾又足够透气的窗纱膜(即窗纱)是本发明人所研究的方向。 [0004] In response to these problems, how to achieve both a sufficient anti-haze and screens permeable membrane (i.e. screens) of the present invention is the direction studied.

[0041] 为了更好的验证本发明的使用效果,下面用实验数据来做更近一步的说明: [0041] In order to verify the effect of the use of the present invention, the following do step closer described with reference to the experimental data:

[0042] 利用负离子吸附或排斥空气中的细微颗粒物,将不失为一个很好的防霾方法。 [0042] With the exclusion or anion adsorbing fine particles in the air, the anti-haze would be a good method. 但是,电荷间的库仑力与距离的平方成反比,即距离越大,作用力越小,如何在有效的距离范围内使电荷的作用力最有效(防霾效果),而开孔孔径能最大(透气量),这将是负离子膜开孔孔径大小的理论与实施依据。 However, the Coulomb force is inversely proportional to the square of the distance between the charge, i.e. the distance, the smaller the force, how to make the most efficient charge force (the effect of preventing haze) within an effective distance range, and the maximum diameter of the aperture can (air amount), it will be negative pore size openings and a membrane embodiment according to the theory.

[0043] 根据库仑定律:F^ kqx /2 ? k = 9.0X IO9Nm2ZC2, Γ [0043] According to Coulomb's law:? F ^ kqx / 2 k = 9.0X IO9Nm2ZC2, Γ

[0044] 以空气中雾霾500ug/m3为计算依据,每mm3雾霾为0.5x10—7Ug;两个点电荷间的夹角假设为0°,即t = .U基本电荷带电e = l .6xl(T19库仑,以每mm3负离子膜释放10个负电荷为例。计算结果得:1' = 16911111,即当微孔窗纱膜的负离子膜4的最大开孔直径为338111]1时,即能有效防止500ug/m3的空气中的雾霾。 [0044] In the air haze 500ug / m3 calculated on the basis, as per mm3 haze 0.5x10-7Ug; assuming the angle between the two point charges is 0 °, i.e., t = .U charged elementary charge e = l. 6xl (T19 coulombs per mm3 anion release film 10 negative charges Example results obtained: 1 '= 16911111, i.e. when the microporous membrane anion membrane screens maximum opening diameter of 4 to 338 111] 1, i.e., can effectively prevent air 500ug / m3 in haze.

[0045] 另外,根据空气动力学原理,当微孔11的孔径小于6mm,开孔率小于40%时,风经过小孔时,在突缩过程中将产生较强的涡流现象,产生冲击损失及多孔射流混合损失,孔径越小,孔密度越小,这种损失越大。 [0045] Further, according to the principles of aerodynamics, micropores when the aperture 11 is less than 6mm, the opening ratio less than 40%, when the wind through the orifice generate a strong swirl in the phenomenon of sudden contraction process, a shock loss porous jet mixing and loss, the smaller the pore size, the smaller the pore density, the greater this loss. 因此,控制负离子膜4适当的开孔率,将会大部分阻挡住室外尘埃进入室内,这也是小孔涡流效应应用于防霾微孔窗纱膜最坚实的理论依据。 Thus, controlling the opening ratio suitable anion membrane 4, most will stop the outdoor dust into the room, which is applied to the anti-vortex effect holes and haze microporous membrane screens most solid theoretical basis.

[0046] 根据以上计算,当负离子膜4开孔孔径小于338um时,即能达到95%以上的防霾效果。 [0046] According to the above calculation, when the film 4 is less than the diameter of the aperture anion 338um, i.e. more than 95% can achieve the effect of preventing haze. 而对室内外气体的交换,由于气体的粒径一般在0.3〜0.4nm,小于pm2.5颗粒物1000〜 10000倍,而且气体永远遵循高浓度向低浓度自由扩散的原理,室内甲醛、二氧化碳等有害气体会畅通无阻的排向室外,而室外的氧气会源源不断的进入室内,因此,室内外气体能够进行高效的交换,最高可达每分钟每平方米33.75m3。 The exchange of gases outside the chamber, since the particle size is generally harmful gases in 0.3~0.4nm, particles smaller than pm2.5 1000~ 10000 times, and the gas will always follow the principle of high concentration to a low concentration of free diffusion, formaldehyde, carbon dioxide and other gas will be discharged to the outside unimpeded, while the outdoor will be a steady stream of oxygen into the room, therefore, indoor and outdoor gas enables efficient exchange of up to 33.75m3 per square meter per minute.

[0047] 所以将电子吸附技术与小孔涡流风阻技术有效的结合,将是防霾微孔窗纱膜制作有力的理论依据,可以达到很好的防霾效果,同时也能达到有效的室内外气体的交换作用。 [0047] Therefore, the electron attachment technique windage and swirl orifice technology effectively binding, anti-haze would be a microporous film forming screens strong theoretical basis, it can achieve a good effect of anti-haze, but also to achieve the effective outer gas chamber the exchange interaction.

[0048] 根据经验公式使负离子膜4的换气量能够满足一定大小的房间的需求,房间所需负离子膜的面积由下述公式计算: [0048] The empirical formula of negative ions film 4 of ventilation to meet the needs of a certain size of the room, the room is desired anion membrane area is calculated by the following formula:

Figure CN105328351BD00071

_,式中S为所需负离子膜的面积,单位为m2 (平方米);V为房间体积,单位为m3 (立方米);Q为负离子膜的透气量,单位为L/h · m2 (升/小时. 平方米)为房间换气时间,单位为h (小时)。 _, Where S is the area of ​​the negative film is required, the unit is m2 (square meter); V is the volume of the room, in units of m3 (cubic meter); Q is the air permeability of the film negative, in units of L / h · m2 ( l / h. square meters) room ventilation time in h (hours).

[0049] 所述Q由下述公式计算:Q = 0.9752X HT3Xr2 XP,式中r为负离子膜的微孔半径, 单位为μπι (微米)为负离子膜的微孔密度,单位为个/cm2 (个/平方厘米)。 [0049] Q is calculated by the following formula: Q = 0.9752X HT3Xr2 XP, where r is the pore radius negative film, the unit is μπι (m) is the density of the microporous film negative, a unit / cm2 ( pieces / cm). 气体通过微孔的运动规律与克努森系数有关,克努森系数Kn = A/R,其中R为微孔半径。 The movement of gas through pores of coefficients related Knudsen, Knudsen coefficient Kn = A / R, where R is the pore radius. 当Kn<0.001时,气体在孔内运动服从分子运动规律;当Kn多10时,气体在孔内流动由流体力学描述,服从Poiseuilie方程。 When Kn 0.001, the movement of the gas <bore moving subject molecule; Kn when over 10, the gas in the pores is described by hydrodynamic flow, subject Poiseuilie equation. 空气分子直径约0.3nm,在标准大气压下其平均自由程λ约为93nm。 Air molecules a diameter of about 0.3nm, which is at standard atmospheric pressure the mean free path λ is about 93nm. 以空气在孔径为200μπι的负离子膜的微孔内的运动为例,其Kn = O.093/25 = 0.01478,因此空气运动介于分子运动和经典流体力学之间。 In the air pore film 200μπι anion is an example of the motion of the wells, which Kn = O.093 / 25 = 0.01478, so that the air and molecular motion movement between classical fluid mechanics. 对不可压缩气体,根据伯努利方程和连续性方程推导,流量正比于微孔截面积,即孔半径的平方。 For non-condensable gases derived continuity equation and Bernoulli's equation, the flow rate is proportional to the cross sectional area of ​​micropores, i.e., the square of the pore radius.

[0050] 人每分钟呼吸16次,每次平均吸入约0.55L空气,则每人每小时吸入空气量为528L。 [0050] 16 people breaths per minute, about 0.55L per average suction air, the intake air per hour per volume of 528L. 若采用IOOcm2,微孔11的孔径为300μπι,微孔密度400个/cm2的负离子膜4来换气,则每小时气体交换量可达1877L,可满足3个人呼吸新鲜空气的要求。 If using IOOcm2, the aperture 11 is a microporous 300μπι, anion membrane pore density 400 / cm2 for 4 to the ventilation, the gas hourly exchange of up to 1877L, 3 individuals meet fresh air requirements. 对于面积为20m2,层高为3m 的房间,其体积V为60m3,当负离子膜4的微孔孔径为300μπι,微孔密度为400个/cm2时,按上述公式计算可得在t时间内换完整个房间空气所需要的负离子膜面积为0.68/t。 For the area of ​​20m2, 3m storey room, 60m3 volume V is, when the negative film 4 was pore size 300μπι, pore density of 400 / cm2, calculated by the above formula may have to change in time t full room air required for the anion membrane area 0.68 / t. 即对于60m3 的房间,若1小时完成换气,则面积为〇.68m2,微孔孔径为300μπι,微孔密度为400个/cm2的负离子膜4就能满足要求。 I.e. room for 60m3, when 1 hour to complete ventilation, the 〇.68m2 area, pore size is 300μπι, pore density of 400 / cm2, 4 to a demand for negative film.

[0055] 以微孔11的孔径为300μπι的负离子膜4为例,其扑捉收集粒子效率与粒子大小有关,对粒径为IOnm至300nm粒子收集效率仅为20 %,对小于IOnm粒子,粒径越小收集效率越高,当粒子小至Inm,收集效率高达到90 %。 [0055] In the aperture 11 of the microporous film 4 300μπι anion example, the capture efficiency of collecting particles the size of particles of a particle size of IOnm to 300nm particle collection efficiency is only 20% of particles less than IOnm, tablets The smaller the diameter the higher the collection efficiency, small particles when Inm, high collection efficiency of 90%. 对300nm以上粒子,粒径越大收集效率越高,当粒子大至1微米,收集效率最低达70 %,粒子大至2.5微米时,收集效率最低可达90 %。 Particles of 300nm or more, the higher the collection efficiency the larger diameter, when particles as large as 1 m, a minimum collection efficiency of 70%, the particles are as large as 2.5 microns, a minimum collection efficiency up to 90%. 与表1相结合,室外空气中90%以上的降尘、飞灰、花粉可被负离子膜4阻挡在外;70%以上的煤灰、 水泥尘、汽车尾气、煤气燃烧、烟道灰、细菌、碳灰、金属尘及烟可被负离子膜4阻挡在外;而室内病毒绝大部分可透过负离子膜4的微孔11随空气流动由室内流到室外;对于室内的细菌、厨房油烟、烟草烟雾和氡及其子体,一部分可透过负离子膜4的微孔11到达室外,其它部分将被负离子膜4表面所释放的负离子和微孔11孔壁扑捉。 Table 1 combined with the outdoor air more than 90% of the dust, fly ash, pollen may be negative outer barrier film 4; 70% or more ash, cement dust, car exhaust, gas combustion, flue dust, bacteria, carbon ash, metal dust and smoke can be blocked out negative film 4; and the majority of the virus chamber 11 may flow to the outdoor air flowing over the indoor anion permeable microporous film 4; bacterial chamber for cooking fumes, smoke and tobacco radon and its daughters, a portion of negative ions arriving at the outdoor permeable microporous film 4 11, the other part will be released and negative ions microporous surface of the membrane 4 hole wall 11 capture.

[0056] 这是由于,当室外PM2.5浓度较高时,也就是污染物粒子浓度较高,由于粒子间的自由碰撞运动,室外气压相对室内气压较高;遵循浓度自由平衡原理,当室外污染物通过防霾微孔窗纱膜流向室内时,在负离子膜4的微孔11上形成涡流现象,大部分污染物被拒之微孔窗纱膜外,只有很小一部分污染物颗粒能通过微孔11,但是当它们通过时又被负离子膜4 所释放的负离子阻挡或吸附,这就是微孔窗纱膜的防霾机理;而对于室内污染物,大家知道,室内污染物诸如甲醛、二氧化碳、氮气、氨气、氡及其子体等大部分均以气态形式存在, 它们的粒径范围大约在0.3〜0.4nm,相对室外污染物粒径相差100〜10000倍,而且气体永远遵循高浓度向低浓度自由扩散的原理,所以它们很容易通过微孔11排向室外,而室外的氧气也会通过微孔11扩散至室内。 [0056] This is because, when high concentrations of outdoor PM2.5, which is a higher concentration of pollutant particles, due to the free movement of collisions between particles, the higher the relative indoor air pressure outside pressure; follow the concentration of free balance principle, when the outdoor when haze preventing contaminants through the microporous membrane screens flow chamber, swirling phenomenon occurs on the microporous film negative 114, the outer screens microporous membrane of most contaminants rejected, only a small portion of the contaminants through the microporous particles 11, but the time and when they are blocked by the negative film 4 is released or the anion adsorption, which is the mechanism of anti-haze screens microporous membrane; for indoor pollutants, you know, indoor pollutants such as formaldehyde, carbon dioxide, nitrogen, ammonia, radon and its daughters, and most are in gaseous form, the particle size thereof in the range of about 0.3~0.4nm, particle contaminants to the outdoor differ 100~10000 times, and the gas will always follow a high concentration to a low concentration the principle of free diffusion, so they can be easily and outdoor oxygen will diffuse through the pores into the room through the micropores 11 11 discharged to the outside. 因此,微孔窗纱膜完全具备防霾换气的作用。 Accordingly, the microporous film is completely screens with anti-haze ventilation effect.
