2. Performance Description
The
product is a electret master granule with homo-polypropylene as the carrier,
which is an essential functional material for the manufacture of non-woven cloth
for the special purpose of melt-spraying masks. The main components are electret
composite material and polypropylene for the special purpose of melt-spraying.
It has electrostatic effect, piezoelectric effect and pyroelectric effect.
The purpose of electret is to make the melting spray layer in the mask non-woven
fabric store static electricity, so that it can absorb (+) positively charged air dust,
bacteria, viruses, aerosols and other harmful substances, so as to improve the filtration
efficiency of the melting spray layer in the mask (up to 95-99%).
3. Use dosing
Series of BFE:1.0-1.5%
Series of PFE:1.5-2.0%
Series of N95/N98/P1/P2:2.5-3.0%
N95/N98/P1/P2系列:2.5-3.0%
Mix evenly with the polypropylene resin according to the appropriate ratio or adjust the ratio
with the masterbatch feeding metering device.
After stable production, the non-woven fabric is charged through the designed electret equipment tunnel .
There are several kinds of charging power supply: filter air electrostatic field generation power supply,
plasma electric field generation power supply, pulse electric field generation power supply.
5. Attention
The effect of electret is related to the polypropylene melting
and spraying materials, production process,
fiber fineness, weight, electret equipment, electret power supply voltage and other factors.
