Background technique
The technique for making hollow membrane uniform wall thickness in hollow membrane forming technology is always that an obstruction hollow membrane expansion uses model
The problem enclosed, especially in functional materials such as tunica fibrosa, hemodialysis film, reverse osmosis membrane, microfiltration membranes, nanofiltration membrane and ultrafiltration membranes
In use, the difference of the wall thickness of these materials determines the difference of effect, thus in the requirement of wall thickness very it is high.
If the wall thickness of different sections is different in a hollow membrane, will lead to hollow membrane can play filter effect at a certain section,
And can not be had effect at another section, or bad in same section of hollow membrane of not ipsilateral wall thickness, it frequently can lead to
Thick side, hinder need to by medium 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.
To guarantee 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, to cause, manufacture efficiency is low, and the manufacturing cost of hollow membrane occupies height not
Under.
In process of production, the branching process each time on a channel is defined as different grades, i.e., divided for the first time
Circulation road is known as first order sub-material by-path, carries out branching process again after first order sub-material by-path, and the shunting after shunting is logical
