Description
Technical Field

The process of preparing the small membrane is generally to manually remove the protective film and then cut the wound membrane of the osmosis membrane to obtain the small membrane.
The mode of cutting the infiltration film and rolling the film comprises full-manual cutting and semi-automatic cutting.
For the full manual cutting, an operator is required to tear the protective film, cut a 300mm (width) ×30m (length) roll of the diafiltration membrane into 10mm (width) ×300mm (length) strips, and then manually cut the strips again, thereby obtaining 30 10mm×10mm small membranes. The cutting mode has the advantages of low production efficiency, high labor intensity, time and labor waste, high production cost and lower yield.
For semiautomatic cutting, a roll of the diafiltration membrane is cut into strips of 10mm (width) by 300mm (length) using a cutting device, and then the strips are manually cut to obtain 30 small 10mm by 10mm membranes. The cutting mode liberates part of human resources, but still does not meet the requirement of automatically cutting the small film, the production efficiency is higher than that of full-manual cutting, the labor intensity is still higher, the production cost is still maintained at a certain level, and the yield is basically the same as that of full-manual cutting.
