Description

technical field [0001] The invention relates to the technical field of filter material processing equipment, more specifically, it relates to a filter material electrostatic electret device. Background technique [0002] Electrostatic electrets, referred to as electrets, refer to those dielectric materials that can store space charges and dipole charges for a long time, that is, from the perspective of time span, their charge decay time constants are much longer than the period of electret formation. The charge of an electret can be a real charge (or a space charge), a dipole charge, or both. Electret air filter material is to use the electrostatic force of electric charge to trap dust particles. [0003] At present, the electret methods mainly include electrospinning method, corona discharge method, triboelectric method, thermal polarization method, low-energy electron beam bombardment method, etc.; due to the different electrostatic electret methods (processes) of materia...
