METHOD FOR MANUFACTURING A POLYURETHANE FRAME-BASED AIR PURIFYING FILTER USING A NON-WOVEN FILTERING MATERIAL AND THE AIR PURIFYING FILTER MANUFACTURED BY THE SAME CAPABLE OF FORMING A POLYURETHANE FRAME BASED ON THE NON-WOVEN FILTERING MATERIAL

摘要

PURPOSE: A method for manufacturing a polyurethane frame-based air purifying filter using a non-woven filtering material and the air purifying filter manufactured by the same are provided to improve the efficiency and dust collecting capability of the filter.;CONSTITUTION: A method for manufacturing a polyurethane frame-based air purifying filter includes the following: A filtering material based on non-woven fabric is curved. A hot-melt resin is applied and cured on both edges of the curved filtering material using an edge(22). The curved filtering material is stabilized. A frame for the stabilized filtering material is formed based on a polyurethane-based material using a desired molding frame.;COPYRIGHT KIPO 2012
