Abstract
The invention relates to the technical field of membrane separation and particularly relates to and discloses a hollow fiber membrane encapsulation technology. The encapsulation technology comprises the following steps: pretreating hollow fiber membrane yarns and vertically putting the hollow fiber membrane yarns into an opened container which is hermetically connected with an encapsulation membrane shell; pouring a protective liquid into the opened container, wherein the liquid level is flush with the lower end surface of the encapsulation membrane shell, the density of the protective liquid is greater than that of encapsulation glue and the protective liquid and the encapsulation glue do not dissolve in each other; pouring encapsulation glue into the opened container according to pre-encapsulation height; standing until the encapsulation glue is solidified; taking out a membrane bundle and the encapsulation membrane shell which are consolidated together; and cutting off membrane yarns along the glue surface at the end surface of the encapsulation membrane shell. According to the encapsulation technology, the glue is prevented from entering a membrane yarn hole by virtue of the protective liquid which neither dissolves in the encapsulation glue, nor affects the membrane yarns, and has density greater than that of the encapsulation glue, and the glue does not need to cut after solidification; the encapsulation technology has the advantages of being simple and feasible, being low in production cost and suitable for large-batched production and having a good encapsulation effect.
Description
Technical field
The present invention relates to membrane separation technique field, relate in particular to a kind of hollow-fibre membrane packaging technology.
Background technology
The encapsulation of hollow-fibre membrane refers to, and single hollow-fibre membrane is built to film silk end by adhesive and become hollow fiber membrane bundle, and cut out the process of revealing the end face that has film silk endoporus.
The crop process of existing hollow-fibre membrane encapsulation is mostly after adhesive solidifies, together with adhesive cut-out end film silk together, to reach the object that cuts out film silk endoporus.But in order to guarantee sealing and the resistance to pressure of hollow fiber membrane bundle, after adhesive solidifies, hardness is higher conventionally, and some operation is to excise together with encapsulating mould, what during crop, use is generally cutter, end face is difficult for neat, easily produces floccule, and crop process expends time in and resource.
In order to make the crop process of film bundle more convenient: patent: ZL201110457953.7, a kind of method for packing of external pressing type hollow fibrous membrane, a kind of method of using laser cutting is disclosed, but laser cutting machine cost is high, and the temperature of laser cutting moment generation is high, easily causes the variable color of end face film silk and glue-line, affects attractive in appearance, if excess Temperature also can cause flexible glue to come unstuck, affect performance.
Summary of the invention
For prior art hollow-fibre membrane packaging technology, exist take time and effort, cost is high, the defect that package quality can not be guaranteed, the invention provides the hollow-fibre membrane packaging technology that a kind of technique is simple, cost is low, packaging effect is good.
For achieving the above object, the present invention adopts following technical scheme:
A hollow-fibre membrane packaging technology, is characterized in that: comprise the following steps:
1) by multiple or multi-beam, hollow fiber film thread one end-grain cutting of shutoff is not concordant, and cover packs in encapsulating film shell, and encapsulation putamina lower surface is stretched out in film silk lower end, is more vertically positioned in open containers, and described encapsulation putamina and open containers are tightly connected;
2) toward perfusion protection liquid in open containers, the liquid level of protection liquid flushes with encapsulation putamina lower surface, and protection liquid is full of film silk endoporus and outside, film silk lower end, and the density of described protection liquid is greater than and is about to the density of the encapsulation glue that pour into and the two is immiscible;
3) in open containers, pour into encapsulation glue, packaging plastic water stratification is positioned at protection liquid top, and encapsulation glue height packaging height is according to actual needs determined;
4) standing a period of time, glue curing to be packaged is taken out the film bundle being consolidated and encapsulation putamina after having solidified from open containers, and protection liquid is stayed in open containers and can again be utilized;
5) the glue face along encapsulation putamina end face has obtained a branch of packaged film bundle by neat the cutting away of unnecessary film silk.
Utilize immiscible with encapsulation glue, film silk be positioned to packaging plastic subsurface layer without impact and the high protection liquid of density ratio encapsulation glue come diaphragm silk hole, make the contact of film silk Kong Buyu encapsulation glue, also just avoid encapsulation glue to enter after fenestra is blocked fenestra and encapsulated and no longer needed to excise glue, only need to excise unnecessary film silk, reduce crop difficulty, reduced glue consumption, reduced cost, and relatively traditional cutting glue, this technique tangent plane is also more smooth attractive in appearance; Owing to using a kind of liquid reusing, energy free consumption, cost is low; Step 1) has been saved the step of coating head with respect to traditional encapsulation, be applicable to producing in batches.
As preferably, the hollow-fibre membrane silk external diameter 0.03 ~ 5cm described in step 1), internal diameter 0.01 ~ 4cm, film silk material is polypropylene, Kynoar, polysulfones, polyether sulfone, polyvinyl chloride, polyamide.This technique is applicable to the hollow fiber film thread of various materials and size.
As preferably, the encapsulation glue described in step 3) is epoxy resin or polyurethane.Epoxy resin and polyurethane bonding performance are good, have good oil resistivity and solvent resistance.
As preferably, step 2) the protection liquid described in is pure glycerin, and its density is 1.26g/cm3.Density ratio epoxy resin or polyurethane are high and immiscible, and low price is easily made.
As preferably; step 2) the protection liquid described in is atoleine, and atoleine also can solidify, and after paraffin solidifies, carries out step 3); after having solidified in step 4), the film bundle being consolidated, encapsulation putamina, solid paraffin are taken out together from open containers.More easily control the perfusion of encapsulation glue, solid paraffin is softer, is easy to cutting.
A kind of hollow-fibre membrane packaging technology of the present invention; utilize immiscible with encapsulation glue, on film silk without impact and the high protection liquid of density ratio encapsulation glue; be positioned at packaging plastic subsurface layer and come diaphragm silk hole; glue is not entered; save the coating head operation before traditional encapsulation; and after solidifying, only need prescind unnecessary film silk, and without cutting glue.Have advantages of simple for process, production cost is low, packaging effect good, tangent plane smooth attractive in appearance, be applicable to batch production.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of hollow-fibre membrane packaging technology embodiment 1 of the present invention.
The specific embodiment
Below in conjunction with Fig. 1 and the specific embodiment, the present invention is described further.
