Repeat with more than 200 hours of more breathable masks to appear in Guangzhou

As we all know, ordinary masks mainly rely on static electricity to adsorption, the material inside is mainly nonwoven fabric, filtering effect is poor, pores are also relatively large, about 3 microns or more. On May 9, according to Guangzhou media reports, the reporter followed the Guangzhou Municipal Bureau of Industry and Information Technology to visit the Huangpu District, Guangzhou Development Zone, Guangzhou Donglu FluoroPlastics Co., Ltd. was informed that a new type of nanofilter mask products officially mass production and release.

New nanofilter masks

On May 9, Guangzhou Daily All Media Reporters followed the Guangzhou Municipal Bureau of Industry and Information Technology to visit Huangpu District, Guangzhou Development Zone, Guangzhou Dongyi Fluoroplastics Co., Ltd. (hereinafter referred to as “Guangzhou Dongyi”) was informed that a new type of nanofilter mask products officially mass production and release. It is reported that this is the first membrane aperture than the new corona virus smaller mask, the appearance looks thinner, but its breathability is better than ordinary melt spray cloth, and reuse time of more than 200 hours, at present, the birth of the new type of nanofilter mask has been developed the country’s first group standards, with listing conditions.

New masks can last more than 200 hours

Affected by the outbreak of new crown pneumonia, during the Spring Festival masks and other medical protective supplies market demand increased sharply, the market supply shortage throughout the country, the supply of raw materials is seriously inadequate, in order to effectively alleviate the problem of insufficient supply of national epidemic protection materials, Guangzhou City mobilize related enterprises, through government-enterprise linkage, rapid organization of resources docking product development, new materials industry and all kinds of killing supplies, medical equipment and protective supplies are inseparable, has become the focus of public relations from all walks of life in Guangzhou. It is reported that during the outbreak, Guangzhou new materials industry enterprises for the production of epidemic prevention materials to provide a strong technical support, nearly 20 new materials enterprises and scientific research institutions for the first time to participate in material supply, material donation, hospital assistance, logistics transportation, research and development testing and other related work.

Guangzhou Donglu fluoroplastics Technology Co. , Ltd. is one of them, according to the introduction, the enterprise is specialized in polymer materials, fluoroplastics, fluorine products, fluoro-rubber and fluorosilicon rubber products research and production, sales in one of the modern high-tech enterprises, its development of Polytetrafluoroethylene nanomaterials can be reused, and applied to masks.

After learning of the above situation, the Municipal Bureau of Industry and Information Technology immediately contacted and communicated with Guangzhou Dongyi, and presided over the coordination meeting of the relevant departments, large state-owned enterprises, testing institutions and other units of the district, together with the New Materials Promotion Association to accelerate the development and application of new nanofilter masks and industrial docking, accelerate the development and application of new nanofilter masks and industrial docking, in a short period of time to solve the enterprise’s power supply expansion and industrial registration needs, so that the enterprise’s mask production line in a short period of time.

On May 9, Guangzhou Daily All Media Reporters followed the Guangzhou Municipal Bureau of Industry and Information Technology to visit the enterprise to see that, in the sterile production environment, two machines for the production of masks open full horsepower production, while entering the mask raw materials, the middle automatic machine processing, the terminal mask formed directly to the hands of workers packaging, very quickly.

Unlike a regular mask, this type of mask lasts more than 200 hours, the new material plays a key role. Guangzhou Municipal Bureau of Industry and Information Technology related office staff told the Guangzhou Daily reporter, nano filter mask has three outstanding advantages: First, the use of PTFE nano-filter film as a protective layer, fiber diameter of only a few tens of nanometers (new coronavirus diameter of 90 nanometers), so that the new mask can directly use the principle of physical isolation, hard nuclear filtration virus, excellent filtration performance (filtration efficiency of more than 99%), more assured.

Nanofilm

The filtration effect did not decrease after 15 times after the hot water drifted clean

Second, can be worn around the clock, filter performance is not wet, sweating, wet weather and so on. Third, the material safety and breathability is good. Food contact grade material, no odor. Wearer body comfort is better than ordinary mask, suitable for children and other sensitive groups to wear, breathability is much better than the general mask.

Why does the new mask have such advantages? Wu Dongjian, the head of the enterprise, told the Guangzhou Daily All Media Reporter that the nanofiltration film is a microporous film formed by the puffed stretching of Teflon resin, with an average aperture of nanoscale, the aperture is about 100 times smaller than the melting cloth, and the pore rate is as high as 80%. The filtration efficiency of the mask prepared with this material reaches more than 99% (N95, KN95 mask level), and the exhalation and suction resistance is far below the standard limit, which can effectively achieve the good effect of breathlessness, filtering PM2.5, resisting microorganisms and bacteria entering the human body.

At present, most of the market uses a melting spray non-woven protective mask, its filter PM2.5 and the mechanism of the virus is electrostatic adsorption, the mask once water, the filter function will fail, so it is necessary to replace every 4 hours, a short service life. The new material used in the mask is Teflon resin (PTFE) which can be used in biomedical, artificial blood vessels, etc., and is non-biotoxic. It was originally used in the space field, this is a cross-cutting application, and the filtering principle is physical barrier, filtering effect is not wet and other factors, more suitable for summer sweating and humid environment, can be worn throughout the day, and can be cleanly used through hot water.

Data from the authoritative testing laboratory show that masks made from teflon nanofiltration membranes can be worn for more than 200 hours without damage. Moreover, the new mask has passed the national standard GB/T 32610-2016 “daily protective mask specification” and medical industry standard YY/T 0969-2013 “one-time use of medical mask” test, as well as safe use test. And has passed the “reusable” performance test, the existing test data show that after 15 hot water drift, the mask filtration efficiency and ventilation resistance did not change.
