Abstract
The invention discloses a novel organic composite tubular membrane, which comprises an organic composite membrane sheet. the organic composite membrane sheet is prepared through compounding an inner filter layer with an outer support layer. The filter layer is made of high polymer materials composed of PTFE, PVDF, PES, PP and regenerated cellulose. The support layer is composed of PET and PP. The thickness of the filter layer is 15-40 [mu]m. The thickness of the support layer is 100-300 [mu]m. The novel organic composite tubular membrane is simple in manufacturing process, efficient, stable in quality, low in operational requirements, and high in hot-melt accuracy. Meanwhile, a hot-melt zone is not easily ruptured and strong in bearing capability.
Description
Technical field
The present invention relates to UF membrane field, be specifically related to a kind of novel organic composite tubular membrane.
Background technology
Tubular membrane usually inside the supporters such as the glass fibre synthetic paper of internal diameter 5-25mm, length 0.3-6m, non-woven fabrics, plastics or stainless steel curtain coating form.Because tubular membrane can keep enough turbulent flows under lower operating pressure, prevent particle to obtain accumulation on the internal layer surface of film, this membranous system therefore can be made to obtain very high Membrane Filtration Flux, extend the service life of film simultaneously.This turbulent flow, cross-flow filtration and major path film pipe, reduce pretreated demand, compares with other membrane structure form, the application that tubular membrane tool is larger and development prospect.
Traditional organic tubular membrane manufacture method generally has two kinds:
Rubbing method: first organic material is made pipe, then by the method such as curtain coating, knifing shape film formation surface;
Sintering process: organic material is made nanometer grade powder, then form tubular membrane by high temperature sintering.
The some self-contained one-tenth of single film pipe a branch of film pipes are placed in plastics or stainless steel cylinder fastening with suitable method location, form tubular membrane component.
The defect of prior art and deficiency: by above-mentioned traditional organic tubular membrane manufacture method, the more difficult control of its preparation condition; Effective film area little (filling rate is low) in unit volume; The sealing of the mouth of pipe is also more difficult, causes tubular membrane production cost high, hampers the extensive use of tubular membrane.
