Since entering the 21st century, the development of international melt-blown nonwoven technology has been rapid, especially the melt-blown non-woven composite filter material which occupies a large market share.
Melt-blown non-woven composite filter material is made of polypropylene ultrafine fibers that are randomly distributed and bonded together. The appearance is white, smooth, and soft. The fiber fineness of the material is 0.5-1.0 μm. The random distribution of the fibers provides an excellent space between the fibers. More opportunities for thermal bonding, thus giving the melted air filter material a larger specific surface area and higher porosity (≥75%).
After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency, and high dust holding capacity.
Melt-blown cloth is the best material for masks. In large, medium and small medical institutions, in areas affected by earthquakes and floods, and in the high incidence seasons of SARS, avian influenza and H1N1 viruses, melt-blown cloth uses its strong filtration performance to Play an irreplaceable role.
However, because there are many pores inside the melt-blown cloth currently on the market, and the arrangement is relatively regular, it is easy to connect with each other and form channels. The mesh is larger, and impurities with smaller diameters can easily pass through, so the filtration effect is not good.
PTFE film manufacturer specializes in the production of melt-blown non-woven composite filter materials. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; production The product materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
