AI Technical Summary
Existing filter nonwoven fabrics have insufficient charge storage capacity under high temperature and high humidity conditions, resulting in charge decay of corona electret filter media and a sharp drop in PM0.3 filtration efficiency.
The filter nonwoven fabric adopts a three-layer structure. The outer layer is a fine filtration layer made of electrospun nanofibers, the middle layer is a high-efficiency electret meltblown polypropylene layer that has been fluorinated, and the bottom layer is a spunbond polyester layer. Combined with corona and water mist polarization treatment, it enhances charge stability and mechanical strength.
It improves charge storage capacity and environmental stability, enhances PM0.3 filtration efficiency, extends service life, and reduces production costs.
