The difference between PFE99 and BFE99 materials

The difference between PFE99 and BFE99 materials

(Summary description)BFE99 is polypropylene as raw material. PFE99 uses high melting index polypropylene raw material. Mask BFE99 test, biofiltration efficiency test on masks. Mask PFE99 test, perform particle filtration efficiency test. The challenge test is usually done with latex particles with ultrafine particle size such as 1.0μm, 0.5μm, 0.3μm, 0.1μm.

Information

BFE99 is polypropylene as raw material. PFE99 uses high melting index polypropylene raw material.

Mask BFE99 test, biofiltration efficiency test on masks. Mask PFE99 test, perform particle filtration efficiency test. The challenge test is usually done with latex particles with ultrafine particle size such as 1.0μm, 0.5μm, 0.3μm, 0.1μm.

PFE99 material

The user has to press the wire on the PFE99 mask to the bridge of the nose, and then spread the entire PFE99 mask along the bridge of the nose to be effective. A rectangular surgical mask can be worn by a child because it has no fixed shape and can fit snugly against a child's face if tied well.

The PFE99 cup-shaped mask must ensure that the mask is dense enough after it is attached to the face, and the exhaled air will not leak out to be effective. When wearing a PFE99 cup mask, you can cover the mask with both hands and try to blow air to check if there is air leaking from the edge of the mask. If the PFE99 mask is not tightly covered, it needs to be repositioned before wearing it again.

Extended information for PFE99:

N series: protection against non-oily suspended particles without time limit.

R series: The protection time limit of non-oily suspended particles and sweat oily suspended particles is eight hours.

P series: protection of non-oily suspended particles and sweat oily suspended particles without time limit.

When the carrier of some particles is oily, and these substances attached to the electrostatic non-woven fabric will reduce the electrical properties and allow fine dust to penetrate, so the filter material for preventing oil-containing aerosols should undergo special electrostatic treatment to prevent fine dust. purpose of dust. Therefore, each series is divided into 3 levels: PFE95%, PFE99%, PFE99.97% (namely referred to as PFE95, PFE99, PFE100), so there are 9 types of filter media.
Through the above introduction and analysis of PFE99, hope it helps you.

The manufacturing process of oil absorbent pads  

Oil absorbent pads are a class of fibers and non-woven fabrics made of inert polypropylene melt-blown that have been specially treated to precisely absorb and retain liquids. The absorbent products of oil absorbent pads are all wrapped in polypropylene fibers or non-woven fabrics sewn with surface-active treatment agents.

Introduction

Introduction of classification of oil absorbent pads

Oil-absorbing cotton products are usually in the form of oil absorbent pads (oil-absorbing sheets), oil-absorbing strips, oil-absorbing rolls, oil-absorbing pillows, and oil-absorbing fences. Oil absorbent pads, such as oil absorbent pads, are suitable for leakage treatment in a small area.

Features

Features of Melt-blown fabric

Melt-blown fabric filter material is randomly distributed and bonded together by polypropylene microfibers. The appearance is white, flat, and soft. The material fiber fineness is 0.5-1.0μm. The random distribution of the fibers of the Melt-blown fabric provides more opportunities for thermal bonding between the fibers.
