After strict national control and the hard work of front-line medical staff, the epidemic has finally been brought under control. Except for Hubei, the epidemic situation showed a downward trend for 7 consecutive days. However, due to the insufficient resumption rate of medical protective equipment manufacturers, the assets of anti-epidemic materials such as masks are seriously insufficient, not to mention expensive, and even if you want to buy it, you can’t buy it.
The mask, which could only be worn once, was worn again. How long have you worn your mask? I believe that there are definitely not a few friends who have been using it for a week. When they can’t buy enough masks, netizens have begun to show their magic and make protective equipment. The wisdom of the working people is immeasurable.
● A large inventory of wonderful masks, which one can prevent the epidemic?
The fruit skin mask is easy to make, with three stars difficult to make. It only needs half an orange and two rubber bands to complete the production, but in fact, the protective effect of this thing is worrying. The strong fruit flavor will only make the sense of smell feel refreshing. The air is cool, in fact, the protection effect against the virus is almost zero, and the airtightness is not enough to block droplets.
Plastic bag mask
There are many types of masks made of plastic bags, and their protective effects are also different.
Some netizens use large plastic bags to cover almost their entire body. This type of protection is relatively better, because the current mode of transmission of the virus is still direct contact and droplet transmission, and the droplet particles are larger and will When it falls on the ground, it is not easy to be directly inhaled into the mouth and nose. The protection level is three stars.
The behavior of putting a plastic bag directly on the head is not worth promoting. The original intention of netizens may be to prevent droplets, but the airtightness is not enough, droplets may enter, and the airtightness is too strong and there is a possibility of suffocation. The protection level is one star.
Bucket masks may be inspired by gas masks, but their protective effects are far from comparable, with a protection level of two stars. It should be noted that the bucket is hard, so netizens must be careful with knives when making them, so as not to cut their hands.
Imitation “real” mask
Imitation “real” masks are the closest self-made type to medical surgical masks. The protective effect is also very good. The protection level is four stars and the production difficulty is also very high. It is the best self-made solution when masks are in short supply.
Medical surgical masks are usually composed of three layers. The outermost layer is made of coated non-woven fabric, which is water-resistant and can prevent blood from splashing. The middle filter layer is made of melt-blown polypropylene electrostatic cloth, which can block droplets, body fluids, For secretions and larger particles in the air, the inner layer is made of ordinary non-woven fabric, which is mainly used for skin-friendly, moisture absorption, and improved user experience.
Material acquisition plan:
Outer layer: The main function of the outer layer of the film-coated non-woven fabric is to prevent water. Although it sounds unfamiliar, it is actually very common. For example, the packaging bags used in many takeaways are this kind of material. Of course, if you really can’t find it It is also possible to use a fresh-keeping bag instead, but in order to prevent the fresh-keeping bag from wearing out, it is best to add another layer on the outer layer of the fresh-keeping bag.
Middle layer: The middle layer is made of melt-blown polypropylene electrostatic cloth, which has high filterability and low resistance. It is the key to mask filtering. This material needs to be purchased separately, HEPA filter paper, SMS non-woven fabric, PP non-woven fabric and PET non-woven fabric Woven fabrics can be used as an alternative.
Inner layer: mainly for comfort and skin-friendliness, gauze is recommended. According to experts, a 12-layer mask can have a certain filtering effect, so the use of gauze on the inner layer is not only comfortable but also increases the filtering effect.
Cut the material to a suitable size, fold it like a folding fan, prepare the needles and thread, stack the materials in order and stitch them together, just like a mask. But don’t rush to wear it after you finish it. It is best to irradiate it with ultraviolet rays or put it in the sun for disinfection and sterilization.
※Because of the different production methods, the protective performance of self-made masks cannot be guaranteed. If you can buy other protective equipment, it is not recommended to make your own.
● You can’t buy masks, please find out about gas masks
Things are scarce, what is the most in short supply in a special period? There is no doubt that it is a mask that can’t be grabbed now! Medical surgical masks, N95, KN95 and even the Korean standard KF94 are the best choices, but they are all unavailable. Even many overseas shopping platforms are out of stock. How to buy masks? Try a gas mask with a higher level of protection.
Gas masks are not only higher in protection level, but also more comfortable to wear. The most important thing is that gas masks are more cost-effective compared to masks that are hard to find. The mask can be cleaned and dried after use, and the filter element can last longer. And can be replaced. However, it is particularly important to note that when purchasing, you must look for the GB2890-2009 or GB2626-2006 production standard. Only the gas mask that meets the standard can have sufficient filtering effect.
● Indoor sterilization depends on these
Relying on masks when going out, is there no need for protection when staying at home? This is true, but purchase materials and collect express delivery. . . . . . We can’t avoid the need to go out. What do we need to do at this time?
Necessary at the door: 75% alcohol
Because the new crown virus can be infected through contact, it is best to spray your body with 75% alcohol when you go out and enter the door, and use alcohol to wash your hands carefully in a 7-step method.
Floor disinfection: 84 disinfectant
84 Disinfectant is a very effective disinfection product, but it must be used with care and cannot be shared with other detergents, otherwise it will produce harmful chlorine, which will cause damage to your health after inhalation.
Air disinfection: air purifier
Many people think that an air purifier is just a dust-eating machine, which can only purify particulate matter such as PM2.5. In fact, an air purifier also has a certain effect on blocking germs. Remember the meltblown polypropylene electrostatic cloth mentioned in the homemade mask? It is one of the common materials of HEPA filter. In addition to using HEPA filters, many purifiers also add ultraviolet rays, active oxygen generators and other devices that can kill germs in the purifier. It is feasible to use air purifiers to kill germs in the air.
