During the epidemic, the most commonly used protective equipment is a mask. Speaking of masks, you may know something about meltblown fabric more or less, but how to distinguish the true from the false? How to identify whether the masks we use are real medical masks? Today, let's take a look.
For us, real medical masks must be three-layer, and only two-layer masks are inferior products. Both sides of the medical mask are anti sticking non woven fabrics, and the middle is meltblown fabric, which is enough grams. As we all know, wearing a medical mask is to filter bacteria, viruses and some particles, and the filtering effect of the mask is related to meltblown fabric. If the mask doesn't contain it, you can't buy it. Because that kind of mask doesn't work at all. The inner and outer layers of the medical mask only play a supporting role, and the melt blown layer in the middle can filter bacteria and viruses. However, its general filtering effect is only 50%. Only after secondary processing and adding electrostatic adsorption function can more than 99% of bacteria and viruses be filtered.
So, how should we distinguish the authenticity of meltblown fabric? In fact, there is a simple way to distinguish it. The first point is to ignite the melt blown layer with fire. If it doesn't burn, it's true. The second point is that the melt blown layer will generate electrostatic reaction. If we tear the melt blown layer into several small strips, we will feel obvious electrostatic reaction. If we put it close to stainless steel, we can also see that its strips will stick to it.
Next, how can we identify the authenticity of medical masks? In fact, the gram number, color and the material of non woven fabrics on both sides of meltblown fabric are related to authenticity. Having enough grams, transparent masks are very different from those that look white and the spunbonded non woven fabrics on both sides look like paper. If it looks a little thin, it's the small number of grams. The thinner it is, the worse the protective effect.
In short, during the epidemic, the role of medical masks has been paid more and more attention. As the "heart" of masks, meltblown fabric is of great importance to medical masks. At the same time, we can also distinguish the true and false medical masks through meltblown non woven fabric.
