| titleOfInvention | A kind of hydrophilic biaxial tension polytetrafluoroethylmicroporous microporous membrane |
| abstract | The present invention relates to the technical field of thin film, particularly provide a kind of hydrophilic biaxial tension polytetrafluoroethylmicroporous microporous membrane.Its water flux is 1,200 3000 kgs/hour square metres (pressure 1 Kilogram Force Per Square Centimeters)；The processing method of polytetrafluoroethylmicroporous microporous membrane comprises the following steps: batch mixing: by teflon resin powder, lubricating oil and inorganic salt powder by weight being mixed evenly for 1:0.2 0.28:0.01 0.2, at a temperature of 40 80 DEG C, stand 10 16 hours, form politef material；The differential scanning calorimetry test degree of crystallinity of described teflon resin powder is 98 99.9%, number-average molecular weight is 200 1,000 ten thousand；Pressed compact and calendering；Longitudinal stretching；Cross directional stretch and thermal finalization.Polytetrafluoroethylmicroporous microporous membrane of the present invention can one-shot forming, its processing method can give thin film entirety hydrophilicity. |
