| 发明名称 | Separation composite membrane and separating membrane module using the same | ||
| 摘要 | A separation composite membrane including: a separating layer for separating fluid components, the separating layer being constituted of a polymer having cross-linked structure, and a porous layer for supporting the separating layer, the porous layer having a maximum pore diameter of 0.05 to 0.5 μm, the separating layer being partly impregnated into the porous layer in the range of 0.1 to 30% in terms of the impregnation amount ratio (ηa) defined by Formula (A): [impregnation amount ratio (ηa){%}=impregnation depth (s)/(membrane thickness (t1) of separating layer)×100] (A). | ||

| 主权项 | 1. A separation composite membrane comprising: a separating layer for separating fluid components, the separating layer being constituted of polyimide resin having a cross-linked structure, and a porous layer for supporting the separating layer, the porous layer having a maximum pore diameter of 0.05 to 0.5 μm, and the porous layer being constituted of at least a resin selected from the group consisting of a polyacrylonitrile resin, a polysulfone resin, a cellulose resin, a fluorocarbon resin, a polyether sulfone resin, a polyamide resin and a polyolefin resin, the separating layer being partly impregnated into the porous layer in the range of 5 to 30% in terms of the impregnation amount ratio (ηa) defined by Formula (A): [impregnation amount ratio (ηa){%}=impregnation depth (s)/(membrane thickness (t1) of separating layer)×100] (A). | ||
