Method of preparing polytetrafluoroethylene powder and polytetrafluoroethylene powder prepared by the same |
| abstract |
Disclosed are a method for producing a polytetrafluoroethylene powder and a polytetrafluoroethylene powder produced by the method. The disclosed method for producing polytetrafluoroethylene powder includes the steps of primary pulverizing waste polytetrafluoroethylene (S10), reforming the primary pulverized waste polytetrafluoroethylene (S20), and the modified waste poly Washing tetrafluoroethylene with ultrasonic waves (S30), drying the washed waste polytetrafluoroethylene (S40), secondary pulverizing the dried waste polytetrafluoroethylene (S50) and and a step (S60) of thirdly pulverizing the second pulverized waste polytetrafluoroethylene. |
