Melt-blown fabric substitute – Nanofiber membrane composite material
Electrostatically spun functional nanofiber membrane has small diameters, about 100-300 nm, It has the characteristics of light weight, large surface area, small aperture and good air permeability etc. Let’s realized precision filters in air and water filter special protection, medical protective material, precision instrument aseptic operation workshop etc., Current filter materials can’t compare with it as the small aperture.
Melt-blown fabric is widely used on the current market, It is PP fiber through high-temperature melting, the diameter is about 1~5μm.
The Nanofiber membrance made by Shandong Blue future , the diameter is 100~300nm
In order to get better filtering effect for the melt-blown fabric in current marketing adopt electrostatic adsorption. the material is polarized by electrostatic electret, with a stable charge. To achieve high filtration efficiency, low filtration resistance characteristics. But the electrostatic effect and filtration efficiency will be affected seriously by ambient temperature humidity. The charge will attenuate and disappear with time. The disappearance of the charge causes the particles adsorbed by the melt-blown fabric to pass through the melt-blown fabric. The protection performance is not stable and the time is short.
Shandong Blue future’s nanofiber is physical isolation, Do not have any effect from charge and environmental. Isolate contaminants on the surface of the membrane. The protection performance is stable and the time is longer.
Because the melt-blown cloth is a high temperature processing technology, it is difficult to add other functions to melt-blown cloth, and impossible to add antimicrobial properties through post-processing. As the electrostatic properties of the melt-blown fabric are greatly reduced during the loading of the antimicrobial agents, Let it has no adsorption function.
The anti-bacterial and anti-inflammatory function of filtering material on market, the function is added on other carriers. These carriers have large aperture, bacteria are killed by impact, the missing pollutant attached to the melt-blown fabric by static charge. Bacteria continue to survive after the static charge disappeared, through the melt-blown fabric, the antibacterial function is greatly reduced, and leakage rate of pollutants is high.
Nanofiber membrane instead of the melt-blown fabric , Lasting protection ; filtration and protection are more efficient. it will be new direction of protection .
