Can air filtration nonwovens filter PM2.5 contaminants?
At present, plastic products are gradually being replaced by filter nonwovens. Because of its degradability, hygienic and environmentally friendly, it will be used in various places. As its name suggests, it also has a filtering effect. Pollutants such as PM2.5 can be filtered.
1. In filtering the non-woven filter material, by adding a magnetized dielectric, the efficiency can be further improved without changing the pressure loss.
2. The non-woven filter material is placed under a high-voltage electrostatic field. The high-voltage electrostatic field is generally a negative voltage. The surface of the fibrous layer of the non-woven fabric is produced and formed in an array direction, and the fiber has a permanent static charge.
3. In addition to the trapping effect of ordinary filter materials, the filter nonwoven fabric mainly relies on the electrostatic effect to adsorb and collect fine dust particles. A filter made of this material has a better blocking effect on PM2.5.
The production process of filtering non-woven fabrics and ordinary fabrics is similar, but some filter materials have been added to the production to make them have a filtering function, so the environmental protection is self-evident.
