Information

At present, the world is actively preventing and controlling the epidemic. The basic protective equipment for residents is masks, while PFE99 melt blown cloth material is the central material for masks, and PFE99 melt blown cloth material mainly uses polypropylene as the main raw material. So how do we distinguish whether the PFE99 melt blown cloth material is qualified? In fact, as long as it is true and false, let's take a look below.

PFE99 material

It is easy to identify the two-tier inferior products. Useful medical masks must have three layers, with spunbonded non-woven fabric on both sides, and PFE99 meltblown cloth material of sufficient weight in the middle. The filtering effect is related to its weight. This range is 18-500g, and the filtering effect is good if the filter is above 40-50g.

PFE99 melt blown cloth material identification method:
1. As the name suggests, PFE99 melt blown cloth material will melt when encountering fire, but will not burn. Paper will burn in fire.
2. PFE99 melt blown cloth material has static electricity. If you tear the melt blown layer into strips, you will obviously feel the electrostatic adsorption effect, and you can also adsorb the strips of melt blown layer on the stainless steel.

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.
