Abstract
The invention relates to a manufacturing method of a hollow fiber membrane component, which is characterized by comprising the following steps: (1) casting first ends of hollow fiber membrane yarns which are equally long by a conventional method, making holes in hollow fiber membrane yarns and trimming the second ends of the hollow fiber membrane yarns to a required length; (2) preparing sealant in a container, plugging the second ends of the hollow fiber membrane yarns in the sealant in the container and to a place 2 to 15 centimeters below the surface of the sealant, and vacuumizing from the first end; (3) closing a vacuum pump and maintaining the pressure between 0.001 and 0.0005MPa till the sealant is solidified; and (4) cutting 5 to 20 millimeters off from the bottom of the second ends of the hollow fiber membrane yarns, and manufacturing the hollow fiber membrane component. In the hollow fiber membrane component manufactured by the method, all of the hollow fiber membrane yarns of an upper cast end are cast together normally and have holes, all of the holes in the hollow fiber membrane yarns of a lower cast end are plugged, and the hollow fiber membrane yarns are separated rather than adhered together.
Description
Technical field
The present invention relates to membrane separation technique, be specifically related to a kind of manufacturing approach of hollow fiber film assembly.
Background technology
Membrane separation technique has been widely used in concentrating and separating, removal of impurities purification of water treatment, fluid etc.But have hollow fiber film assembly now and have strict such as preliminary treatment, as to have operation dead angle, lifting cleaning difficulty, stretcher strain and fracture deficiency, the membrane module that the applicant has developed single-ended plug-hole, freely swung.It can use at all occasions that current hollow-fibre membrane is suitable for, and is particularly useful for the relatively poor environment of raw water quality.But present known manufacturing approach, and the manufacturing approach announced of patent are 200710196205.1 " manufacturing approach of hollow fiber membrane filter element " like the application number of Asahi Chemical Industry, all can not reach the purpose that single-ended plug-hole, film silk freely swing without exception.
Summary of the invention
The object of the invention is for the problem and the defective of the existence that overcomes prior art, and provides a kind of manufacturing approach of hollow fiber film assembly, the hollow fiber film assembly that the present invention comes out casting to reach the purpose that single-ended plug-hole, film silk freely swing.
The technical scheme that the present invention solves its technical problem employing is:
A kind of manufacturing approach of hollow fiber film assembly; It is characterized in that carrying out according to the following steps: the good and hollow-fibre membrane silk perforate of known method hollow-fibre membrane silk one end that some length are identical casting is pressed in (1), and with all hollow-fibre membrane silk second end-grain cutting together to needs length; (2) in container, prepare sealing, all hollow-fibre membrane silk second ends are stretched into the sealing 2-15mm in the container, vacuumize at first end then; (3) close vavuum pump, keep-0.001--0.0005MPa solidifies until sealing; (4) excise all hollow-fibre membrane silk second 5-20mm of bottom portion, then the film silk scatters automatically and can't be sticked together, and makes hollow fiber film assembly.
Described sealing except that present known epoxy resin, polyurethane, can select softening point at 50-120 ℃ PUR, paraffin, chlorinated paraffin wax.
After the casting of first of doughnut membrane module is accomplished, second end of hollow fiber film assembly is put into sealing, vacuumize, there is pressure differential inside and outside making hollow-fibre membrane silk cavity.The sealing of hollow-fibre membrane silk endoporus highly is higher than outer wall.Solidifying back excision outer wall has the part of glue, and then the hollow-fibre membrane silk reaches whole plug-holes and purpose that the hollow-fibre membrane silk can freely swing naturally.
The top casting end hollow-fibre membrane silk of the prepared hollow fiber film assembly of the present invention is all normal to be poured into a mould together and the perforate of hollow-fibre membrane silk, the whole shutoff in hollow-fibre membrane silk hole of following casting end, but be separated from each other between the hollow-fibre membrane silk, do not bond together.
Description of drawings
Fig. 1 makes the sketch map of hollow fiber film assembly for the present invention.3 refer to what and please write out among the figure
The specific embodiment
Below in conjunction with accompanying drawing the present invention is carried out detailed explanation:
As shown in Figure 1; A kind of manufacturing approach of hollow fiber film assembly; Carry out according to the following steps: the good and hollow-fibre membrane silk perforate of known method hollow-fibre membrane silk one end that some length are identical casting is pressed in (1), and with all hollow-fibre membrane silk second end-grain cutting together to needs length; (2) in container, prepare sealing, all hollow-fibre membrane silk second ends are stretched into the sealing 2-15mm in the container, vacuumize at first end then; (3) close vavuum pump, keep-0.001--0.0005MPa solidifies until sealing; (4) excise all hollow-fibre membrane silk second 5-20mm of bottom portion, then the film silk scatters automatically and can't be sticked together, and makes hollow fiber film assembly.
As shown in Figure 1; A kind of manufacturing approach of hollow fiber film assembly; Carry out according to the following steps: the good and hollow-fibre membrane silk perforate of known method hollow-fibre membrane silk one end that some length are identical casting is pressed in (1), and with all hollow-fibre membrane silk second end-grain cutting together to needs length; (2) in container 5, place 62 ℃ of left and right sides PURs of softening point of fusion, and need insulation; All hollow-fibre membrane silk second ends are stretched into 5mm in the PUR in the container, stop 2min; After end cap 4 tightened, be connected with vavuum pump 1 and vacuumize, middlely connect accurate vacuum meter 2; (3) close vavuum pump, keep-up pressure-0.002Mpa; Being cooled to PUR solidifies; (4) excise all hollow-fibre membrane silk second 10mm of bottom portion then; Can obtain then that hollow-fibre membrane silk hole is all blocked but the effect of disperseing between the hollow-fibre membrane silk.
