NANOFIBER FILTER MEDIUM WITH THE IMPROVED COHERENCE FORCE USING A HOT MELT SHEET, A GAS TURBINE FILTER AND A BAG FILTER USING THEREOF, AND A PRODUCING METHOD OF THE NANOFIBER FILTER MEDIUM

摘要

PURPOSE: A nanofiber filter medium, a gas turbine filter and a bag filter using thereof, and a producing method of the nanofiber filter medium are provided to improve the filtration efficiency of the filters by forming nanofibers on both surfaces of a substrate layer.;CONSTITUTION: A nanofiber filter medium(100) comprises the following: a substrate layer(110); and nanofiber adhesive layers(120a,120b) combined to both sides(111a,111b) of the substrate layer. A producing method of the nanofiber filter medium comprises a step of preparing the nanofiber adhesive layers including a nanofiber layer attached to the hot melt sheet by electro-spinning, and a step of heat-fusing the nanofiber adhesive layers to one of the surfaces of the substrate layer.;COPYRIGHT KIPO 2011
