Filter material and manufacturing method of filter material

Abstract

The invention provides a filter material of a filter as well as a manufacturing method of the filter material of the filter. The contact areas between a raw filter material and interval maintaining parts decrease, so that a large gathering area is ensured and the raw filter material is prevented from being damaged, and the gathering efficiency is relatively high. The raw filter material capable of gathering particles contained in filtered gases bends at multiple parts to form a plica-shaped filter material of the filter. The filter material of the filter comprises a plurality of bending parts, a plurality of flat panel parts as well as interval maintaining parts, wherein the plurality of bending parts are formed by bending the raw filter material; the plurality of flat panel parts are formed by plate-shaped areas except for the bending parts in the raw filter material and are configured oppositely; the raw filter material is formed among the flat panel parts in at least one side of the raw filter material so as to maintain an interval between every two adjacent flat panel parts; the interval maintaining parts are formed in a mode that contact angles between the interval maintaining parts and the raw filter material are over 90 degrees.

Description

technical field [0001] The present invention relates to a filter material formed by bending a filter material capable of trapping particles contained in a gas to be filtered into a pleated shape (performing a pleating process), and a method for manufacturing the filter material. Background technique [0002] Conventionally, as filter media used in clean rooms of factories producing semiconductors and liquid crystals, such as Figure 4 The filter medium 100 as shown is shown (refer patent document 1). The filter material 100 is formed by bending a filter material raw material 200 configured to trap particles contained in a gas to be filtered in a folded shape at multiple places. [0003] The filter material 100 includes: a plurality of curved portions 100a, which are formed by bending the original filter material 200; In 200, the plate-shaped regions other than the curved portion 100a are formed and arranged to face each other; interval. [0004] The spacer 300 is formed b...

Problems solved by technology

In addition, if the contact area between the spacer 300 and the filter material raw material 200 increases, the gap between the filter material raw material 200 and the spacer under the influence of thermal shrinkage of the rib 300a when the spacer 300 is formed will be formed. The contact portion between the holding parts 300 generates stress, which may damage the original filter material 200
