Nano silver antibacterial mask
The key to reusable silver nano antibacterial mask (planar) is the material -- silver nano non-woven fabric, which is the core nanotechnology and patent of Anxin Nano Biotechnology (Zhuhai) Co., LTD.
According to the wearing test results of The Hong Kong Polytechnic University, after 8 hours of wearing, the total number of bacteria on the surface of the nano silver antibacterial mask (planar type) is still far lower than the national medical mask industry standard YY/T 0969-2013, the bacterial content is less than 100cfu/g, and the bacterial filtration rate is as high as 99.7%, which can be used repeatedly.
However, the total number of bacteria on the surface of ordinary masks on the market after 4 hours of wearing exceeds the national medical mask industry standard YY/T 0969-2013, and the bacterial content is less than 4-5 times of 100cfu/g.
The first layer (surface layer) is 25-30g / ㎡ PP non-woven cloth, the second layer is 25g / ㎡ melting spray cloth for filtration, the third layer is 38g / ㎡ nano-silver anti-bacterial non-woven cloth, and the fourth layer (inner layer) is 20g / ㎡ water-wet PP non-woven cloth.
This structural change can be used for antibacterial medical care masks and antibacterial medical surgical masks. The main difference is that the antibacterial surgical masks have a PP non-woven layer thickened and treated with water repellent to prevent the penetration of superficial blood spray.
The structure of the inner layer of hydrophilic non-woven cloth is to avoid direct contact with the mouth and nose of nano-silver antibacterial non-woven cloth, which is considered to be safer. The design of the hydrophilic type of the layer enables the exhaled moist gas of the mouth and nose to be quickly absorbed by the water-absorbent nano-silver non-woven cloth.
As the nanometer silver non-woven fabric produced with the patented technology of Anson Company has the characteristic of "stronger antibacterial ability when exposed to water", the humidity of the nanometer non-woven fabric will also be significantly increased with the increase of wearing time, which will promote the release of highly active silver ions by nanometer silver particles and effectively kill bacteria or viruses.
On January 29, 2020, the online edition of People's Daily "Face to Face with Folk Voice" exclusively reported that "Recently, yu Zujiang, an expert from the National Center for Disease Control and Prevention, after testing, has confirmed that the antibacterial efficiency of trivalent silver ion is 60,000 times as high as that of alcohol, and it has the inhibitory effect on novel Coronavirus. The most special thing is that it has both antibacterial and antiviral effects for a long time".
Thus, it can be suggested that the antibacterial mechanism of Anson nano silver antibacterial mask is the same as that of releasing active silver ions through absorbing water.
Compared with traditional masks, the main advantage of nano silver antibacterial masks (flat type) is that they effectively improve the antibacterial efficiency of masks. One nano silver antibacterial mask (flat type) can be worn for 56 hours, equivalent to 14 disposable surgical masks.
And overcome the malpractice of endogenous harmful bacteria reproduction, wear comfortable for a long time without odor.
Nano silver antibacterial mask (flat) yellow face layer to wear.
When not wearing it, put it in a ventilated place to dry. The next day, you can continue to use it or use a hair dryer after two or three minutes of hot air blowing, no cooking is needed, and the service cycle can be up to 7 days (8 hours of continuous wear every day).
