Introduction of reusable masks
With the recent spread of the new coronavirus, the production capacity of masks is not very abundant. Many people do not have enough masks, which affects their normal life. Some people even go out without wearing masks because they do not have enough safety awareness, but because they have no masks, and they have to go out. .
However, the life circle of ordinary people is not often exposed to viruses. Frequent replacement of masks will result in a certain waste of resources, and it is also very uneconomical and environmentally friendly. If the masks can be used repeatedly, these problems can be greatly solved. The pressure on masks It can reduce and allow front-line personnel who really need masks to obtain sufficient resources. Assuming that a mask can be used repeatedly 5 to 10 times, the number of masks consumed in a week is equivalent to the number of masks consumed in a day today. From this point of view, the research How to make masks reusable is far more important than stepping up mask production. So finding a scientific and reasonable disinfection method for the reuse of masks should be a very worthy concern of people from all walks of life. The government can organize experts to conduct professional experiments and tests, engineers can design related products for marketization, and the media can teach the public about how to reuse professional masks.
Reusable masks are more economical
This reusable mask from Xinni Textile solves this problem. We all know that the common sense problem of mask reuse is that masks mainly block and absorb harmful substances through filter materials. Here, our harmful substances are mainly understood as droplets or virus particles. The common answer on the market is that the mask needs to be replaced after wearing it for 4 hours. The reason for replacing the mask is because there are more harmful substances on the mask, and the adsorption efficiency of the mask will decrease due to long-term use.
The rationale for reusable masks
Professional experiments have shown that ordinary masks can be reused at least ten times, and their filtration efficiency will not be greatly reduced. More bold experimental conclusions can be used for 50 times. The filtration efficiency of ordinary masks will not be greatly weakened. . Filtration efficiency is not affected, what about harmful substances? As mentioned above, the harmful substances we mainly think are viruses or droplets, and these things can be removed by disinfection. Common household disinfection methods are: heating and drying, cooking, spraying disinfectant alcohol, etc. There are also professional and senior media experiments here, saying that although these methods can kill viruses, they will destroy the mask fibers and affect the filtration efficiency of the masks.
How to clean a mask
Regarding the question of how to clean the mask, we can see from the experimental data that the disinfection methods such as cooking and spraying alcohol will lead to a decrease in the filtration efficiency of the mask, but ultraviolet disinfection and heating drying have little effect on the mask, and more experimental data show that After disinfection, the filtration efficiency of the mask has been improved, and the influence of experimental errors cannot be ruled out. However, we can know that ultraviolet disinfection and heating and drying will not have a great impact on the filtration efficiency of the mask.
Through these experiments, we can see that masks are reusable. This reusable mask can filter more than 95% of tiny particles with a diameter of 75 nanometers. When worn normally and cleaned in time, the filtering effect remains stable. And also more economical.
