| description | A filtration membrane according to the present invention has a cylindrical structure including a joint unit provided with a fusion layer including a heat-fused fluorine-based resin between the first and second ends of a filtration membrane sheet including a fluorine-based porous membrane and a mesh-shaped support provided on at least one surface of the porous membrane, wherein the thickness (T3) of the fusion layer is 50 to 200 ㎛, and the melting point of the fusion layer is 280 to 350 deg. C, which is lower than the melting point of a filtration membrane sheet material.
본 발명에 따른 여과막은, 불소계 다공질막과 상기 다공질막상의 적어도 일면에 구비되는 메시형 지지체를 포함하는 여과막시트의 제1단부와 제2단부 사이에 열융착된 불소계수지를 포함하는 융착층이 구비된 접합부를 포함하는 원통형상 구조체이고, 상기 융착층의 두께(T3)는 50 내지 200㎛이고, 상기 융착층의 용융점은 상기 여과막시트 재료의 용융점보다 낮은 280 내지 350℃인 것을 특징으로 한다. |
