Abstract
A processing method of a base material sheet includes winding out the base material sheet wound up by a first core and a first porous sheet wound up by a second core, winding up by a third core the base material sheet and the first porous sheet to be overlapped with each other, and processing the base material sheet by a first processing liquid held in the first porous sheet; and winding out the base material sheet and the first porous sheet overlappingly wound up by the third core, winding up the first porous sheet by the second core, and winding up the base material sheet by the first core.
Claims19
A processing method of a base material sheet comprising:
- winding out the base material sheet wound up by a first core and a first porous sheet wound up by a second core,
- winding up by a third core the base material sheet and the first porous sheet to be overlapped with each other, and
- processing the base material sheet by a first processing liquid held in the first porous sheet;
- and
- winding out the base material sheet and the first porous sheet overlappingly wound up by the third core,
- winding up the first porous sheet by the second core, and winding up the base material sheet by the first core.
A base material with grafted polymer chain,
- wherein a width is 0.8 m or more, a length is 1 m or more, and a thickness falls within a range from 30 μm to 200 μm,
- wherein a maximum value of a graft polymerization rate is 115% of an average value of the graft polymerization rate or less, and
- wherein a minimum value of the graft polymerization rate is 85% of the average value of the graft polymerization rate or more.
An ion exchange membrane including a base material with grafted polymer chain,
- wherein a width is 0.8 m or more, a length is 1 m or more, and a thickness falls within a range from 30 μm to 200 μm,
- wherein a maximum value of an ion exchange capacity is 115% of an average value of the ion exchange capacity or less, and
- wherein a minimum value of the ion exchange capacity is 85% of the average value of the ion exchange capacity or more.
