Variety of materials professional masks into hot products

The increase in hazy weather has made masks such as masks that cannot be used on weekdays become hot products. The types of masks are not only more and more diverse but also more professional.

“The 3M masks are all sold out of the madness. In the case of poor air quality, hundreds of them can be sold every day.” said Wang Bo, who runs a 3M mask store at Tmall, “the main defense of such protective masks. The object of resistance is particulate matter. By covering the mouth, nose, and chin part of a person, it forms a space that is sealed to the face and is forced by human inspiration to filter the polluted air."

Wang boss said this kind of mask, looks a bit exaggerated, more like professional protective masks. Its body is usually made of anti-particulate filter material, fixed by the headband or ear strap, the seal at the human face is usually helped by the metal nose clip to help shape, but also rely on other methods to achieve, and some are still in the mask nose clip Add seals to parts. Since there are no parts that can be replaced, the mask needs to be completely discarded after failure, also known as a disposable mask, or a maintenance-free mask.

Currently available on the market 3M masks generally have organic vapor odor and particulate protective masks, these masks contain special activated carbon layer, can remove organic vapor odor; welding particulate protective masks, it has a special filter cotton and flame retardant outer layer, Suitable for particle protection in welding environments; acid gas odor and particulate respirator, it also contains a special activated carbon layer that removes acidic gas odors.

"In the case of severe haze, wearing a mask should always be better than not wearing it." A box of 3M masks has been purchased for himself and his family. Ms. Ma, who lives in the West Area of ​​Beijing's Shijingshan District, said that "most of the time, It is an ordinary cotton mask, but the fiber of the cotton mask is generally very coarse, it can not effectively filter smaller particles, the protection effect is not guaranteed, and it is easy to breed bacteria.The 3M mask production is relatively more professional, and the protection effect is relatively good. Protection."

Now, the concept of PM2.5 is well-known, and PM2.5 masks came into being. It is understood that it uses air filter material technology, 0.25 micron level, can prevent virus intrusion. In the mask filter, powder-free granular activated carbon is also added in the middle. Because the traditional activated carbon fiber mask is coated with a layer of carbon powder on the filter fiber, there is a part of the fine carbon powder particles in the fiber cloth, which is certain for users suffering from lung diseases. Impact. The refined granular activated carbon can not only deeply purify the dust, but also can adsorb toxic gases and further improve the safety of the mask.

The main material of the PM2.5 mask is the use of non-woven fabrics, filter paper, etc., and the most important is the use of lead carbon cloth, can play a better anti-virus function. It has hanger-style, strap-up, head-worn and other styles, of which the ear-mount type is more convenient and comfortable to use. PM2.5 masks are generally disposable masks. Try not to use them twice or more, otherwise the effect is not good.

"PM2.5 masks greatly exceed common masks in terms of filtration efficiency, air permeability, antibacterial properties and safety, and can filter and block PM2.5, bacteria and viruses, automobile exhaust, second-hand smoke, and formaldehyde air pollution." A site’s slogan was written as such.

In addition to the functional upgrades, changes in styling have also brought a lot of attention to the mask. There is a mask resembling the shape of a pig's nose that once became popular, becoming the first choice for many young consumers. The shape of this mask is just like a pig's nose. After wearing it, it is exactly in the nose of the person. It looks like wearing a cartoon mask. The image is a bit funny.
