Abstract
The present invention relates to a kind of hollow fiber ultrafiltration membrane hole blocking method, it is characterised in that carry out according to the following steps: 1) smoothed out with the fingers by Board Lot hollow fiber ultrafiltration membrane silk along being bundled into pencil, load film shell; Pencil hollow fiber ultrafiltration membrane film silk one or both ends are cut flat; 2) emulsion paint, putty powder and water being proportionally configured to stifled hole glue, each substances in percentage by weight meter, wherein emulsion paint to be 65%-75%, putty powder be 1%-2.2%, water are 22.8%-34%; 3) the stifled hole glue configured is evenly coated in cuts on flat film tow end face in the complete shutoff in film silk hole. Above-mentioned stifled hole operation just enters follow-up epoxy sealing casting operation after completing. The man-hour of film pipe plug opening operation can be reduced to the 10% of former technique process man-hour by aforesaid method compared with traditional film pipe plug opening method, and substantially increases production efficiency under the prerequisite ensured the quality of products.
Description
Technical field
The invention belongs to polysulfone hollow fiber ultrafiltration membrane system manufacturing technology field, particularly relate to a kind of hollow fiber ultrafiltration membrane hole blocking method.
Background technology
Polysulfone hollow fiber ultrafiltration membrane system is made up of hollow fiber ultrafiltration membrane silk, epoxy resin embedding adhesive, pipe core, hollow fiber ultrafiltration membrane plastic shell. manufacturing of polysulfone hollow fiber ultrafiltration membrane system is that on dress silk platform, hollow fiber ultrafiltration membrane is organized into pencil, two ends put mesh bag after tying, then hollow fiber ultrafiltration membrane tow is loaded in polysulfone hollow fiber ultrafiltration membrane system plastic shell, make hollow fiber ultrafiltration membrane tow in being axially placed in polysulfone hollow fiber ultrafiltration membrane system plastic shell, again hollow fiber ultrafiltration membrane tow two ends plugging material brush is blocked up, and inject epoxy resin embedding adhesive and the space between each hollow fiber ultrafiltration membrane silk is carried out shutoff, need to cut away cast layer after solidification completely, expose the interior hole of hollow fiber ultrafiltration membrane silk. what select for hollow fiber ultrafiltration membrane tow two ends plugging material at present is that terra alba and water are allocated according to a certain percentage, then block up with hairbrush brush, wait 10min-15min, after gypsum becomes dry completely, film silk end face is dialled loose, and the gypsum powder being clipped between film silk must be cleaned out, then carry out next procedure, dial the loose and cleaning about 3min-5min of gypsum.
Summary of the invention
It is an object of the invention to solve existing technical deficiency, it is to increase production efficiency and quality product, it is provided that a kind of hollow fiber ultrafiltration membrane hole blocking method, the film silk hole of shutoff of the present invention, not only not needing to wait that latex becomes dry, nor need cleaning, namely brush can carry out next procedure after having blocked up at once.
The present invention realizes the technical scheme that above-mentioned purpose adopts:
A kind of hollow fiber ultrafiltration membrane hole blocking method, it is characterised in that carry out according to the following steps: Board Lot hollow fiber ultrafiltration membrane silk is smoothed out with the fingers along being bundled into pencil by (1), loads film shell; Pencil hollow fiber ultrafiltration membrane film silk one or both ends are cut flat; (2) emulsion paint, putty powder and water being proportionally configured to stifled hole glue, each substances in percentage by weight meter, wherein emulsion paint to be 65%-75%, putty powder be 1%-2.2%, water are 22.8%-34%;(3) the stifled hole glue configured is evenly coated in cuts on flat film tow end face in the complete shutoff in film silk hole.
In step (2), the concocting method of stifled hole glue is: by water and putty powder according to the rules ratio pour in agitator, stirred even with the rotating speed of 400r/min; Then pour into respectively in agitator for two parts that the emulsion paint of regulation ratio are divided into equivalent, first part of emulsion paint is poured in agitator, stirs after 10-30 minute, then pours the 2nd part of emulsion paint into, churning time is identical with the churning time of first part, stirs obtained stifled hole glue after terminating.
After hollow fiber ultrafiltration membrane of the present invention stifled hole operation completes, just enter follow-up epoxy sealing casting operation. The man-hour of film pipe plug opening operation can be reduced to the 10% of former technique process man-hour by the inventive method compared with traditional film pipe plug opening method, and stifled hole glue brush is complete carries out subsequent processing immediately, and substantially increases production efficiency under the prerequisite ensured the quality of products.
