Melt-blown non-woven fabrics are made of polypropylene, and the fiber diameter can reach 0.5-10 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt blown non woven fabrics has good air filtration properties. , is a relatively good mask material. In large, medium and small medical institutions, in disaster-stricken areas affected by earthquakes and floods, and in the high incidence of SARS, avian influenza and H1N1 viruses, melt blown filter paper plays an irreplaceable role with its strong filtering performance effect.

The melt blown non-woven fabric is mainly used for:

　　 1. filter material

　　 2. Medical and health materials

　　 3. Environmental protection materials

　　 4. clothing material

　　 5. battery diaphragm material

　　 6. wiping material

How to distinguish the quality of melt blown non-woven fabric

Two-layer inferior products are easy to identify. A useful medical mask must have three layers, with spunbonded non-woven fabric on both sides, and a melt-blown fabric with sufficient weight in the middle. The picture shows the melt blown non-woven fabrics, and the filtering effect is related to its weight (grams per square meter). This range is 18-500g, and the filtering effect is good for 40-50g or more. Do not buy masks without melt-blown non-woven fabric! Identify the true and false melt-blown masks. "A good melt-blown non-woven fabric looks white rather than transparent because it weighs enough. It looks obviously different from the spunbond non-woven fabrics on both sides. In other words, it looks like paper. If it looks different but obviously thin, it is a melt-blown non-woven fabric with a small weight. The thinner the melt-blown non-woven fabric, the worse the effect.

　　 Simple identification method:

　　 First, as the name suggests, the melt blown layer will melt when it encounters fire, but will not burn. Paper will burn in fire.

　　Second, the melt blown layer 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 strips of the melt blown layer on the stainless steel.
