Materials for liquid filtration

The melt-blown nonwoven fabric(Cloth Face Mask Wholesale) can also be used as a liquid filter material, which can filter particles with a particle size of 0.22 to 10 μm. Such as bacteria, blood and large molecular substances. Mainly used in the filtration of photoresist in the electronics industry, the filtration of pharmaceutical, biological, and synthetic plasma products in the pharmaceutical industry, the filtration of beverages, beer, and syrups in the food industry, the fine filtration of electroplating solutions, the filtration of water purification in water plants, the purification of tap water, and the electrolysis Filters for hydrogen production from water, environmental wastewater filtration, etc.

PP melt-blown non-woven fabric with hydrophilic properties can be used to make cell phone battery separators.

Insulation material

The melt-blown nonwoven fabric(Melt-Blown Non Woven Manufacturer) has the characteristics of large specific surface area, small void (pore size ≤20μm), high porosity (≥75%) and so on. For example, the specific surface area of ​​melt-blown nonwoven fabric fibers with an average diameter of 3 μm [equivalent to an average fiber linear density of 0.0638 dtex (denier of 0.058 denier)] is 14617 cm2 / g, and an average diameter of 15.3 μm [equivalent to an average fiber thread The specific surface area of ​​the spunbond nonwoven fabric fiber with a density of 1.65 dtex (fineness of 1.5 and)] is only 2883 cm2 / g.

Because the thermal conductivity of air is much lower than that of ordinary fibers, the air in the pores of the melt-blown nonwoven fabric makes its thermal conductivity smaller, and the heat loss through the fiber material of the melt-blown nonwoven fabric(Medical Meltblown Filter Factory) is very small, and there are countless The static air layer on the surface of the fine fibers prevents the heat exchange that occurs due to the flow of air, so it has a good heat insulation and warming effect.

Polypropylene (PP) fiber is the smallest thermal conductivity coefficient among the existing fiber materials. After special treatment [such as adding 35% high special (coarse denier) PET three-dimensional crimped fiber], the melt-blown thermal insulation flake made of PP fiber, The thermal performance is 1.5 times that of down and 15 times that of ordinary thermal cotton. Especially suitable for making ski wear, mountaineering wear, bedding, sleeping bags, thermal underwear, gloves and shoes. Products with a basis weight of 65 ~ 200g / m2 have been used to make warm clothing for soldiers in cold areas.
