UN METODO MEJORADO PARA LA FABRICACION DE UN ELECTRETO FIBROSO |
摘要 |
A process of manufacturing an electrostatically charged filtration medium is disclosed. A web made of nonconductive thermoplastic fibers is contacted on each side with a more conductive web to form a combined web. The combined web is charged with electrically charged particles from corona charging elements on opposite sides of the web. The charging elements are operated at a voltage of from 5 to 25 kV but with opposite polarity. |
