Information
1.Quality PFE99 melt blown cloth chooses permanent electret masterbatch
Electret means charging. The electret quality PFE99 meltblown cloth reaches the 95+ level at first, but the filter effect drops after a few days of exposure, mainly because the electrostatic field is extremely unstable and the charge attenuation causes the filter effect to attenuate.
The electret masterbatch produced by the gas-silicon method has high efficiency and good durability. It basically belongs to permanent electricity storage, is easy to disperse, is non-toxic and tasteless, and can pass FDA certification. It seems that it has more advantages on the whole. This is because the electrostatic effect of these electret materials due to the electret greatly improves the electrostatic adsorption capacity of the material, and the particles will be strongly adsorbed when they pass near the electret fiber.
2. The quality PFE99 melt blown cloth should be packaged in time to avoid moisture regain
The environmental humidity has an impact on the generation and loss of static electricity. The moisture in the air and the charge of the melt-blown cloth will be converted into negative ions, and the loss of charge will affect the filtration efficiency.
The temperature and humidity in the workshop should be monitored at all times, and corresponding equipment should be added to keep the temperature and humidity in the workshop within a certain range.
The quality PFE99 melt blown cloth should be packaged in time after it is produced, preferably in vacuum packaging, and stored in a dry place, not in contact with the outside moist air. Avoid regaining moisture and staining.
In addition, pay special attention to the fact that melt blown cloth produced by different machines should not be put together, as they will affect each other and the charge will be neutralized.
3. Electret equipment should use positive charge
Dust, bacteria, and viruses in the air are attached to the particles and are mainly negatively charged. The quality PFE99 meltblown cloth is positively charged and easily adsorbs these negatively charged particles.
Electret equipment should use positive charge, not negative charge. Because the cloth has a positive charge, it can absorb the negative charge in the air. The quality PFE99 meltblown cloth is in contact with the skin, and the negative charge is more easily consumed. If it is positively charged, it will wear off more slowly.
