Electrostatic water resident melt blown fabric productionline(TRW1600-MBM)
The difference between thewater-electret melt blown cloth technology and the melt blown clothmanufactured by the traditional process is: the traditional melt blown clothuses corona electret, which exhibits obvious stability and comprehensivebenefits; while the water electret melt blown cloth The prepared pure water isdelivered to the nozzle through the high-pressure water pump, and the meltblown cloth is sprayed by the fan nozzle, and the two rubbing to generatestatic electricity; the water electret melt blown cloth is saturated withstatic electricity and the static electret time is long !
First.Introduction of electret
Electret refers to a dielectric material with long-termcharge storage function. The stored charge can be a unipolar real chargeinjected from the outside, or a dipole charge formed by the orderly orientationof dipoles in a polar dielectric. Or both types of charges exist at the sametime.
Second. What ispure water with water electret?
Water electret ultrapure water equipment usesultrafiltration, reverse osmosis, EDI and nuclear ion exchange systems toproduce ultrapure water that meets the needs. And the wastewater generated inthe production process is recycled and reused through the treatment of themembrane system.
Third, Theprinciple of water electret melt blown fabric
The corona electret was commonly used before. After themicrofiber substrate is collected, it can be subjected to corona treatment tomake it an electret. The water electret melt blown cloth is a high-pressurewater pump to deliver the prepared pure water to the nozzle, and the ultra-purewater is sprayed to the base cloth with special water electret master batch,and static electricity is generated by the friction between the water and thecloth surface to achieve the electret effect. The performance of the waterelectret melt blown fabric is that the amount of static electricity issaturated, and the static electret time is long.
Fourth,water electrets melt blown fabric
Waterelectret technology is still relatively rare in the market, and it is somewhatmysterious. Let me briefly introduce it. First of all, the water electrettechnology can make the melt blown cloth achieve low resistance (about 3-40%resistance reduction), high efficiency (oil up to 99.97), no attenuation (up tomore than 2 years); in other words, it reduces air resistance In the case ofthis, it can increase the filtration efficiency.
Soin general, water electret is an ideal product to replace corona electret
