| titleOfInvention | Preparation method of enhanced polyvinylidene fluoride regenerated composite membrane |
| abstract | The invention discloses a preparation method of an enhanced polyvinylidene fluoride regenerated composite membrane, which comprises the following steps: (1) treatment of waste membrane filaments: (a) cleaning; (b) drying and crushing; (c) carrying out ultrasonic chemical treatment; (2) preparing a casting solution; (3) and (3) preparing the enhanced regenerative composite membrane. The method has the advantages of simple process steps, strong operability and low requirement on equipment, and can be used for preparing the reinforced PVDF regenerative composite membrane with stable performance and large-scale production by cleaning the waste membrane filaments, particularly by crushing the membrane filaments and then carrying out ultrasonic vibration chemical treatment, and strictly controlling the adding proportion of regenerative granules after effectively removing impurities. |
