Description
Technical field
The present invention relates to hollow membrane molding fields, and in particular to a kind of in line combined type spinning head.
Background technology
So that the technique of hollow membrane uniform wall thickness is always one in hollow membrane forming technology hinders hollow membrane expansion to use model
The problem enclosed, especially the functional materials such as tunica fibrosa, reverse osmosis membrane, microfiltration membranes, NF membrane and ultrafiltration membrane in use, these
The difference of the wall thickness of material determines the difference of effect, in the requirement of wall thickness very it is high.
If the wall thickness of different sections is different in a hollow membrane, it can cause hollow membrane that can play filter effect at a certain section,
And can not be had effect at another section, or the wall thickness of not homonymy in same section of hollow membrane is bad, frequently can lead to
Thick side, hinder need to by medium by be unable to reach filter effect, and excessively thin side then needs the medium of filtering also to lead to
It has crossed hollow membrane and has also been unable to reach corresponding filter effect.
Thus in order to ensure the consistency and accuracy of hollow membrane wall thickness in the production process of some hollow membranes, only with
Single spinning head manufactures hollow membrane, and manufacture efficiency is low to causing, the manufacturing cost of hollow membrane occupy it is high not
Under.
