Abstract
Disclosed is a method for preparing an unbreakable micro-electrostatic filter, which comprises: using raw materials obtained by the secondary granulation, cutting after extrusion moulding to obtain an electrode material isolating and carrying frame, arranging an interval-retaining spacer between the upper panel and the lower panel of the electrode material isolating and carrying frame, arranging a strip-shaped conductive material with a preset size on a surface of the electrode material isolating and carrying frame at regular interval in a direction perpendicular to the quadrilateral air channel to obtain a basic filtering plate, then stacking basic filtering plates to form a filter mold base, hot-melt cutting a micro-electrostatic filter with a required size out of the filter mold base through relative movement of the filter mold base and the heating wire, wherein each edge of the micro-electrostatic filter is subjected to hot-melt cutting, to form a micro-electrostatic filter with completely sealed electrodes.
