The Meltblown cloth, how does it filter viruses in the environment?
1. The inertial impact of virus droplets through the air can spread over long distances.
2. Although the size of the new coronavirus is very small, about 100 nanometers (0.1 microns), the virus cannot exist on its own. The main transmission channels are secretions and droplets when sneezing. The size of the droplets is about 5 microns.
3. The Meltblown cloth is essentially a fiber filter. After the virus-containing droplets approach the meltblown cloth, they will also be electrostatically adsorbed on the surface and impermeable.
熔喷布空隙这么大，是怎么过滤环境中的病毒的呢？
1. 病毒飞沫透过空气的惯性撞击，可以远距离传播。
2.虽然新型冠状病毒尺寸很小，在100纳米（0.1微米）左右，但病毒无法独立存在，其传播途径主要有分泌物和打喷嚏时的飞沫，飞沫的大小在5微米左右。
3.熔喷布本质上是一种纤维过滤器，包含病毒的飞沫靠近熔喷布后，也会被静电吸附在表面，无法穿透。
The surface of the used mask is the most contaminated and cannot be reused.
用过口罩的表面最为污染，不可重用.
