1、Electret An electret is a dielectric material that stores charge for a long period of time. The charge stored may be a real unipolar charge injected from the outside, a dipole charge formed by the ordered orientation of a dipole in a polar dielectric, or both

2、What is pure water at the pole of water? The ultrafiltration ultrapure water equipment USES ultrafiltration reverse osmosis EDI and nuclear level ion exchange system to produce ultrafiltration water to meet the demand and recyles the waste water generated in the production process through the membrane system treatment

3、Principle of water in a melt-blown fabric before corona is commonly used in pole, when micro fiber base material collection, make its by corona treatment, also can make its become the electret water in extremely melt-blown fabric by high pressure water pump to the preparation of pure water to the nozzle, ultrapure water spray to add private water in muli base fabric, through water and rubbing on electrostatic, so as to reach the effect in a water in a performance of melt-blown cloth for static electricity saturation, and electrostatic in very long time

4、At present, water stationer spraying water technology in the market is still relatively rare, some mysterious let me briefly introduce first of all, water stationer technology can make melting spraying cloth to achieve low resistance (about 3-40% resistance reduction) efficient (oil 99.97) non-attenuation (up to more than 2 years); In other words, in the case of reducing air resistance, the filtration efficiency can be improved. Therefore, in general, water electret can replace corona electret, but its cost will be increased correspondingly
