Is the nuclear pore film screen effective? Is the nuclear pore membrane screen reliable?

It depends on what screen you choose, there are four kinds of anti-haze screens on the market, one is the nano-coated anti-haze screen, this kind of screen sounds full of science and technology, but the nano-level screen is difficult to breathe under atmospheric pressure, which seriously affects air circulation. The second is the anti-haze screen with the principle of electrostatic adsorption, the principle of which is to generate negative electrostatic electricity when the natural wind blows through the screen, and uses the characteristics of negative static electricity to repel the negatively charged particles in the fine dust at the same level, which plays a certain blocking role in the dust and pollen of large particles. Although the electrostatic anti-haze screen has a certain effect on some large dust and pollen, there is a congenital limitation of electrostatic resistance

Subject to the natural environment, the premise of the static electricity is to have wind, but the haze day is just windless weather, and the haze will naturally dissipate with the wind, and this IQ is estimated to be recharged. The third is the nuclear pore membrane anti-haze ventilation screen, which relies on a high-energy heavy ion cyclotron to accelerate heavy ions (heavy charged ions), form ion (nuclear track) tracks on the surface of food-grade PET materials, and then form a single-layer precision filter screen with a dense and vertical pore structure through high-tech precision (chemical etching) reaming processing technology. According to the principle of aerodynamics, the vortex generated by the natural flow of air in the micropores is used to block large-size dust (haze) particles.

In the process of adsorption and condensation or repulsion of negative ions and dust with high energy and small migration range, the particles become larger and heavier, and finally control the settlement near the window sill, so as to achieve the effect of anti-haze and dust reduction. Not all screens are anti-haze, and not all anti-haze screens are ineffective, it depends on how you choose! This is the anti-smog technology analysis post I saw in Sina Home, the main question is that if you are interested, you can search for it yourself!

Shanghai Gu Qi, it is said that the effect is good, ** is so expensive.

Nuclear pore membrane can be a breakthrough technological invention, the use of nuclear energy as a new energy, in electronics, food, chemistry, pharmaceutical, biology, environmental science and other fields play its irreplaceable role, with the development of science and technology, nuclear pore membrane will have a wider range of applications.

The nuclear pore film anti-haze screen is a patented product developed by Tsinghua University, which has won ten invention patents and one national scientific and technological achievement award, and is an excellent product with leading anti-haze indicators.

What I heard from people close to the Institute of Modern Physics of the Chinese Academy of Sciences is another version, the nuclear pore membrane anti-haze screen was invented and put on the market by Shanghai Gu Qi under the cooperation of the Institute of Modern Physics of the Chinese Academy of Sciences, and many invention patents can be retrieved.

If it is not ventilated, it is to add a layer of film to the ordinary screen window, and there are particularly small holes on the film, and the wind blows outside, and the house is stunned. You buy plastic wrap at the vegetable market, stick it on, and pierce a few holes, and the effect is almost the same.

Nuclear microporous membrane is a new type of filtration membrane. Because the filter pore of the nuclear microporous filter membrane has a regular geometry and uniform pore size, it is basically a cylindrical straight pore, and the particles larger than the pore size are trapped on the surface of the filter membrane during filtration, which is suitable for transverse flow filtration or backflushing to improve the life of the filter membrane. And because the filter membrane itself is a dielectric film, there is no pollution of the filtrate by the filter membrane itself, so it is an ideal tool for precision filtration and sieving particles.

You can also make a protection, Puweixin meets the highest standards of medical masks imported from the United States, has good filtration, and is not only anti-particulate but also anti-droplet. It can filter particles as small as microns and bacterial or viral vectors (commonly found in droplets) as small as microns. With SecureFit patented technology, it can be adjusted to adapt to different face shapes to achieve a high fit.

At the same time, the six-point support disperses the pressure, there are no strangulation marks on the face, and it is very comfortable to wear j@22 d there.

Assuming that the continuous index bursts the table, reaching 500 microgram cubic meters, the particles that enter the micropores are completely adsorbed, and it takes 4 months for the micropores to be blocked by half (according to this calculation, in the most serious area of Beijing's haze, it will be used continuously for more than 2 years and does not require any cleaning), because the particles follow the Brownian motion, the state of movement is free and disorganized, and the particles that actually enter the micropores are much less than theoretically, so the actual use time of the screen window is longer, even if there is dust falling on the outer side, The surface of the functional film is smooth and tense, and it runs away when the wind blows.

The nuclear pore membrane ventilation window of Lvchuang Hexing can be taken off after about a year of use and rinsed on the smooth side with a watering can commonly used at home, and it should not be brushed with a brush.

I don't know, don't have to prevent it at home, just eat more food to clear the lungs, simply put, haze is composed of a variety of particles that are harmful to the body, so go out to prevent haze, the United States imported Puwei Xintian ,,, cat can block micron particles, so protection is very important, care for yourself, start from me, I hope to help you, hope to adopt.

It is not ventilated at all, it is very poor, don't buy it, it has the same effect as if you closed the window directly. And the visual impact is particularly powerful, and you can't see the outside clearly when you put it on.

The characteristics of Tianci anti-haze ventilation window screen: 1. Efficient blocking of air pollutants pollen, etc., and its blocking efficiency is higher than 98%; 2. The indoor and outdoor gas exchange resistance is small, the air exchange volume is greater than cubic meters (minutes and square meters), and the indoor air is kept fresh and the oxygen is sufficient at any time; 3. Pattern pattern, beautiful decorative effect, change the screen screen is just a monotonous screen, so that your screen window becomes a beautiful scenery; 4. Soft lighting, avoid direct sunlight. The United States imports the Pwit Xintian cat.

Ultrafiltration membrane screen is the best dustproof screen The density of his sand can filter the pore size of only 150 nanometers, and other screens are at least above 5000 nanometers (2500 nanometers in diameter).

What are nanofibers?

Fibrous material with a diameter of 1 1000 nm and a length of more than 100 times the diameter.

1m=1，000mm=1，000，000um=1，000，000，000nm

In general, when air comes into contact with an object, the speed will decrease due to air resistance, but substances with a nanometer size of 100 nm or less will cause a slippery phenomenon, so the speed tends not to decrease.

Expected effect: In nanometer size, the capture capacity is increased due to the increased intermolecular gravitational pull.

Normally, the capture capacity increases and the pressure loss increases, but the pressure loss is reduced due to the slippery nature of the nanofibers.

Pressure effect. Reduced pressure loss: The slip flow effect theoretically increases when the fiber diameter decreases.

However, in fact, when the fiber diameter is less than 100 nm, the pressure loss decreases.

Biggest feature] Prevent the entry of yellow sand, pollen, volcanic ash and pests (pollen capture rate is about 99%)

The performance of the screen installed on the window focuses on ventilation and mosquito prevention, and the dust prevention effect is weak. The recommended measure is to replace the screen mesh with a 20-mesh encrypted screen, which has a small mesh hole and is still feasible to block small flying insects and dust.

There is a lot of dust in the windows facing the street, which kind of screen window is more obvious to prevent dust, at this time, you can use the upper core pore film dustproof and anti-haze screen, the effect of blocking dust is obvious, and the window can only be ventilated but not ventilated.

The haze screen can be matched on all kinds of screens, such as sliding screens, casement screens, drop-down screens and other specifications can be transformed, and professional personnel can solve them.

Diamond yarn has the advantages of good hardness and high strength, whether it is fixed on the wall or the form, it will have good enough bearing capacity and is not afraid of the invasion of outsiders. The high-quality alloy steel screens are all treated with electrophoretic paint, which is not afraid of corrosion in humid environments, fierce sunlight or harsh environments.

I think the air purification screen window of Chengdu Kelinmeiya is really good, and the window sill at home is obviously less gray, and I heard that the building of the National Patent Office is equipped with the same style as them.

The dust effect of the screen window is limited, and there is no kind of dust protection.

Diameter 1: Slip flow effect.

Theoretically, the diameter of the fibers becomes smaller due to the increase in intermolecular gravitational pull.

Pressure effect. A reduction in pressure loss, 000, will reduce the pressure loss. 5 nanofibers with a diameter of 2500 nm) are.

1m = 1, so the speed does not tend to decrease, but due to the slippery phenomenon of nanofibers, other screens are at least above 5000 nm (PM2, and the pressure loss will also increase, and the length of the fiber material is more than 100 times the diameter, the speed will decrease, 000um = 1.

Usually the catching capacity increases, yellow sand, 000: in the nanometer size.

The expected effect is that there will be a slippery phenomenon, 000nm

Under normal circumstances, the air comes into contact with the object, but the nanometer size of the substance below 100nm, due to the air resistance, the pressure loss is reduced, 000mm=1, the pressure loss will rise, and the ultrafiltration membrane screen is the screen with the best dust-proof effect The density of his sand can filter PM2 and pollen. 5

The pore size is only 150 nm, but in fact, the fiber diameter is less than 100 nm.

The stainless steel wire screen has a good dustproof effect.

For the same mesh of yarn, the effect is the same when it is new.

After using it for a while.

Stainless steel yarn yarn, non-static, easy to clean, corrosion resistance;

Yarn woven from plastic nylon has static electricity, is difficult to clean, and is easy to age;

The yarn woven with iron wire and copper wire is non-static, easy to clean and easy to corrode.

Due to the high yarn ** of stainless steel silk weaving, the store usually does not stock up, so it is necessary to make a reservation.

The screen window is mosquito-proof, and if it is dust-proof, it is better to close the window.

The kind that is more compact, dense.

It's best to prevent PM2 5, you have new information I want to know.

<> has no effect. It depends on which brand the product is... It's not just a screen that is called an anti-smog screen!

Compared with the nuclear pore membrane and electrostatic adsorption, the anti-smog screen of nanofiber can be better, which can ensure ventilation and lighting, and Qingdao has a nanofiber technology research institute.
