Height, thermal contraction is small, prevents battery from not shrinking in applied at elevated temperature or abnormal high temperature；Organic solvent-resistant does not occur with electrolyte anti-
It should wait.
In existing wet process diaphragm production technology, scraping fluid is one of the critical process of diaphragm production.After diaphragm leaves extraction tank,
The separation that a large amount of methylene chloride carry out methylene chloride and diaphragm into next link can be carried, using between liquid sweeping roller and diaphragm
Mutual extrusion realizes the separation of most of methylene chloride and diaphragm, then so that remaining methylene chloride is volatilized by high temperature.
Existing technical solution is to pass through the pressure between control diaphragm and multistage liquid sweeping roller by the way of multistage liquid sweeping roller
Power, the methylene chloride being gradually disengaged out in diaphragm.Into before dry section, the methylene chloride of membrane surface gradually volatilizees, and diaphragm is micro-
Methylene chloride in hole enters next process with metacneme then by volatilizing when dry section.
Currently, liquid sweeping roller moves in the same direction with diaphragm in scraping fluid process, when liquid sweeping roller is separated with diaphragm, liquid sweeping roller with every
Liquid-sheet disintegration at membrane junction forms drop, and drips are on diaphragm.Since methylene chloride volatilization is rapid, ambient temperature
Height, drop have little time just to have volatilized in membrane surface wetting levelling, and big and small watermark is left in membrane surface.Multistage is scraped
The mode of liquid roller can reduce the severity of watermark, but still not can avoid the generation of watermark.
