A brief introduction to the FFP2

A brief introduction to the FFP2

(Summary description)The FFP2 mask is a disposable filtering respiratory protection device that protects against particles such as dust and aerosols (such as invisible smaller fog). Aerosols that we release when we cough or breathe can contain viruses, such as the H1N1 or COVID-19 coronaviruses. Aerosols can also be released from industrial equipment (such as air cooling towers) and may contain amoeba and bacteria (such as Legionella, which are pathogenic to humans).

Information

The FFP2 mask is a disposable filtering respiratory protection device that protects against particles such as dust and aerosols (such as invisible smaller fog). Aerosols that we release when we cough or breathe can contain viruses, such as the H1N1 or COVID-19 coronaviruses. Aerosols can also be released from industrial equipment (such as air cooling towers) and may contain amoeba and bacteria (such as Legionella, which are pathogenic to humans).

FFP2 Manufacturers chinaWhat does FFP2 mean? The letters FFP correspond to the English acronym "Filtering Facepiece". The number after the FFP letter corresponds to one of three categories of respiratory protective masks: FFP1, FFP2, and FFP3: in order of increasing effectiveness.
The effectiveness of a mask, such as FFP2, is based on the filtration efficiency of the materials that make up the mask, and also depends on the restriction of air passage between the mask and the face (a properly adjusted mask, i.e. with a well-shaped face, reduces air circulation and is, therefore, more protective).
Through the above introduction and analysis of the FFP2, 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.
