Introduction of PFE99 masks

Introduction of PFE99 masks

(Summary description)There are all kinds of masks on the market, but not all of them are suitable, even if there are many kinds of N99 masks. If you want to effectively block bacteria from flying, you must recognize the various English characters on the mask packaging before purchasing, such as PFE99, VFE99. At present, the most common masks on the market are mainly divided into cotton masks, surgical masks, activated carbon masks, PFE99 masks and sponge masks. Most masks can block dust, but not all masks can block flying. To reduce the spread of germs, it is best to choose medical surgical masks. Surgical masks such as PFE99 are mainly composed of three layers, the surface layer is waterproof, the middle layer is filtration and the inner layer is moisture-absorbing.

Information

There are all kinds of masks on the market, but not all of them are suitable, even if there are many kinds of N99 masks. If you want to effectively block bacteria from flying, you must recognize the various English characters on the mask packaging before purchasing, such as PFE99, VFE99.

China PFE99

At present, the most common masks on the market are mainly divided into cotton masks, surgical masks, activated carbon masks, PFE99 masks and sponge masks. Most masks can block dust, but not all masks can block flying. To reduce the spread of germs, it is best to choose medical surgical masks. Surgical masks such as PFE99 are mainly composed of three layers, the surface layer is waterproof, the middle layer is filtration and the inner layer is moisture-absorbing.

If people want to know whether the mask can block the fly, they must pay attention to whether BFE, PFE and VFE are printed on the package. If PFE99 is listed on the package, it means that the mask can block 99% of the particles. The higher the value of the three, the representative The better the filtering ability. And BFE, PFE99 and VFE are mainly the particle filtration rates of different sizes.

Through the above introduction and analysis of PFE99, hope it helps you.

How

How the Melt-blown fabric is constructed

The following paragraph of this article will introduce the related production process of Melt-blown fabric. The production process of Melt-blown fabric is mainly divided into three steps: melt extrusion, melt-blown process, and electret treatment. Specifically, Melt-blown fabric uses high-speed hot air flow to draw the extruded polymer melt through the spinneret holes of the die nozzle. From this, microfibers are formed and collected on a condensate screen or drum, and at the same time self-bond to become a Melt-blown fabric.

Reasons

Reasons why Melt-blown fabric becomes brittle after production

1. If the aspect ratio of the spinneret of Melt-blown fabric is small, the holes are thick and short. After the polymer is sprayed, the fibers are thicker, the gaps are larger, and the water absorption is stronger for a long time , so the Melt-blown fabric is neither soft nor brittle.

The features of BFE 99 masks

BFE in BFE 99 masks means bacterial filtration effect, which refers to the material's resistance to bacterial penetration. The reported results of BFE 99 masks are shown in percentage data, corresponding to the ability of the material to resist bacterial penetration. The higher the value, the better its filtration performance.
