Ultra-thin 3D nano-film mask: anti-haze ability reaches industrial-grade standards
Taiwan has launched an ultra-thin anti-haze mask. Its nano-membrane filter material can not only make its anti-haze ability meet industrial-grade standards, but also maintain smooth breathing and keep it dry and hygienic for a long time. This mask has 5 layers of protection, and has obtained the anti-counterfeiting authorization certification of "PM2.5 Protective Mask", and the filtration rate of PM2.5 is as high as 98.7%.
The use of this filter material subverts the traditional anti-haze technology. Most of the traditional anti-haze masks use electrostatic melt-blown non-woven filter materials. The anti-haze method is mainly electrostatic adsorption and probabilistic blocking, but often due to the poor moisture resistance of the material, static attenuation is often caused, and the anti-haze performance is therefore unstable. And this
mask can not only isolate PM2.5 and other particles as small as 100 to 200 nanometers in diameter, but also ensure long-lasting and stable anti-haze performance with its strong moisture resistance.
The most important thing is that this anti-haze mask is only 8.3 yuan each.
TPU film material gives sportswear a "breathing" channel
For the "breathable" apparel industry, Wanhua Chemical has launched customized film material solutions, including high, medium and low moisture permeability film TPU products. All in one, to provide the public with sportswear that breathes like the skin, making sports healthier, comfortable, happy and fashionable.
Different moisture permeability, moisture permeability can be from 2000 g/m2×day to 10000 g/m2×day, to meet diverse needs; excellent water resistance, hydrostatic pressure can reach 10000mm water column, with good hydrostatic pressure performance; High strength, ensuring good puncture resistance and long-term wearability of clothing; product safety, environmental protection, suitable for oil glue and hot melt adhesive compounding; excellent low temperature flexibility, ensuring clothing is still as soft as skin at -35 °C , comfortable.
This film can be "stealth"
Andrei Grigoriev, general manager of the Russian Prospect Research Foundation, told RIA Novosti that Russian scientists have developed a film similar to foreign products, which can resist small, small particles, including viruses. Dangerous ions can also make people invisible.
The resulting filter material samples are far more efficient at intercepting the smallest, dangerous aerosol ions—viruses, toxins, and allergens—than similar products. This newly developed technology could become the basis for building a wide range of protective equipment for medical, military and other uses.
"Longevity Film" has a lifespan of up to 25 years
A film as thin as a sheet of paper can last for more than 2,000 hours even in extreme weather with a temperature of 85°C and a humidity of 85% (Double 85 experiment), which is equivalent to 25 years. This "longevity film" was recently released in the laboratory of Zhejiang Jingmao Technology Co., Ltd.
The solar fluorine film adhesive-coated interconnected backplane is a new product developed by the "Jingmao Technology" scientific research team for more than 3 years. It has successfully filled the domestic gap, obtained 2 national invention patents, and set up a project for scientific and technological research in Keqiao District in 2015. project. In the second half of 2014, the new product was officially industrialized, and it immediately became the "new favorite" of domestic and foreign solar backsheet demand companies, with sales increasing year by year.
3-micron ultra-thin film achieves mass production
A film that looks like a plastic wrap is only 1/4 of the thickness of a human hair, but it can withstand hundreds of kilograms of heavy objects, and it will not be broken down by thousands of volts. This product is mainly used to produce film capacitors used in home appliances, new energy vehicles, photovoltaics and wind power. Compared with traditional products, film capacitors are small in size and high in power.
According to the industry, this magical 3-micron ultra-thin polypropylene capacitor film has been mass-produced and passed the acceptance. Previously, this product technology has been monopolized by foreign companies such as Japan's Toray and Germany's Genesis. The success of this technology broke the monopoly of foreign technology. Shen Shilin, deputy director of the thin film department of Sichuan Dongfang Insulation Materials Co., Ltd., said that the company's output of capacitor films is expected to exceed 9,000 tons this year, and the annual output value will increase by nearly 100 million yuan.
Shen Shilin said that at present, the market price of 3-micron capacitor film per ton is nearly 100,000 yuan, while the price of 6-8 micron capacitor film per ton is only about 20,000 yuan. A newly released market analysis report on China's capacitor industry shows that in 2019, the size of the capacitor market will exceed 100 billion yuan, and the market prospect of film capacitors with low loss, low impedance and strong voltage resistance is promising.
Introduction of film:
A film is a thin, soft, transparent sheet made of plastic, adhesive, rubber, or other materials. The scientific explanation of polyester film is: a two-dimensional material formed by the deposition of atoms, molecules or ions on the surface of the substrate. Such as: optical film, composite film, superconducting film, polyester film, nylon film, plastic film and so on. Films are widely used in electronic appliances, machinery, printing and other industries.
Thin-film materials are thin metal or organic layers with thicknesses ranging from a single atom to a few millimeters. Electronic semiconductor functional devices and optical coatings are the main applications of thin film technology.
