Water electret

The water electret technology originated from 3m in the United States. The water electret has high efficiency and low resistance. Generally,99% filtration efficiency can be achieved with 15-25g cloth. The difference with traditional melt blown fabric electret lies in that: the traditional melt blown cloth uses corona electret, and its surface electret is obvious, but the filtration efficiency can not reach the peak value and the storage will decrease with time. The static electricity on the surface of the material will decay obviously, and its static electricity will remain electric The most important factor is that the filtration efficiency has hardly decreased after high temperature and humidity aging test.

The water electret melt blown cloth is to deliver the prepared pure water to the spunlace device through the high-pres-

sure water pump, and the fan-shaped nozzle sprays the melt blown cloth, and the friction between the two results in static electricity generation; the performance of the water electret melt blown cloth is saturated with static electricity, and the water electret charging method can detect the oil and salt, which can effectively solve the improvement of electret filtration efficiency of melt blown cloth in the mask industry and the issue of post-storage degradation.
