Abstract
A method for preventing membrane fiber from being broken by undercut includes producing according to the existing manufacturing method of hollow fiber membrane module by use of secondary casting, wherein the material of the secondary casting is epoxy resin. The method for preventing membrane fiber from being broken by undercut in the invention has the advantages of simple production, convenient processing, structural durability, excellent effect for preventing membrane fiber from being broken by undercut, and especially is effective in production of curtain membrane for MBR and protection for its membrane fiber. The ultrafiltration membrane module assembled by using the membrane module produced by the method is high in treatment efficiency, stable and safe in membrane module operation, and greatly improves service life and has excellent and stable effluent water quality.
Description
Technical field
The present invention relates to a kind of be used in the Novel hollow cellulosic ultrafiltration membrane module, prevent the method that film silk undercut wrecks.
Background technology
At present, mostly the curtain type membrane used of pillar hollow fiber ultrafiltration membrane or MBR is film silk bundled form with epoxy resin Feng Qiliang end afterwards of dividing into groups.Because hardness is very large behind the epoxy resin cure, when carrying out water treatment, the film silk shakes under the state that waterpower flows, and very easy the shearing by hard epoxy resin of film silk root wrecked, and this is the main cause that causes polysulfone hollow fiber ultrafiltration membrane system to damage.In order to overcome this difficult problem, have the people at film silk root with the silicon rubber second pouring preventing film silk Undercutting Phenomenon, but because the bad adhesion of silicon rubber and epoxy resin causes the phenomenon of coming unglued, not only do not solve the undercut problem, increased all the better the possibility of fracture of wire.And the difficulty during second pouring is very large, and implementing very is difficulty.
Summary of the invention
Technical problem to be solved by this invention provide a kind of have produce simply, it is convenient, durable in use to implement, and can effectively prevent the membrane module production method that the film silk wrecks.
The present invention is by the following technical solutions:
A kind of manufacture method of hollow fiber film assembly may further comprise the steps:
(a) produce according to the manufacture method of hollow fiber film assembly, still adopt the method for second pouring.
(b) key is that the material of second pouring remains epoxy resin, and just this Resin Flow is good, and toughness is splendid after solidifying, and is very good with the caking property of epoxy resin, can peeling off phenomenon, can effectively prevent the generation of film silk Undercutting Phenomenon.At first carrying out the end-blocking cast with original epoxy resin, but after solidifying, carry out second pouring at the epoxy resin of mentioning with this patent, is that machinable becomes final membrane module after solidifying fully.
The invention has the advantages that and produce simply, easy to process, durable in use, prevent the film silk undercut effect excellence that wrecks, particularly for MBR with the production of curtain type membrane and very effective to the protective effect of its film silk.So that the milipore filter piece treatment effeciency of assembling with the membrane module of the method production is high, the membrane module stable and safe in operation, the life-span improves greatly, and effluent quality is excellent stable.
The specific embodiment
With the membrane module that method of the present invention is produced, film silk root is pliable and tough round and smooth, can not consist of shear action to the film silk, belongs to the membrane module production field.A kind of manufacture method of hollow fiber film assembly is produced according to the manufacture method of hollow fiber film assembly, still adopts the method for second pouring.Key is that the material of second pouring remains epoxy resin, and just this Resin Flow is good, and toughness is splendid after solidifying, and is very good with the caking property of epoxy resin, can peeling off phenomenon, can effectively prevent the generation of film silk Undercutting Phenomenon.At first carrying out the end-blocking cast with original epoxy resin, but after solidifying, carry out second pouring at the epoxy resin of mentioning with this patent, is that machinable becomes final membrane module after solidifying fully.
Claims (1)
1. method that prevents that film silk undercut from wrecking is characterized in that may further comprise the steps:
(a) produce according to the manufacture method of existing hollow fiber film assembly, adopt the method for second pouring;
(b) wherein the material of step (a) second pouring is epoxy resin.
