Cordless Jump Rope Device

Abstract

The present disclosure relates to a method 200 for producing polytetrafluoroethylene (PTFE) thorium oxide membrane. The method 200 comprising combining metal oxide and polytetrafluoroethylene (PTFE) powder to form a first mixture and screening the first mixture to remove aggregates. The method 200 also comprising mixing a lubricant, wetting agent, and optional pigments to form a second mixture and spraying the second mixture over the first mixture. The method 200 also comprising compacting the homogeneous product into a preform and extruding and calendaring the preform to obtain a tape of desired thickness. The method 200 also comprising heating the tape formed to evaporate the lubricant and sintering the tape to fuse polytetrafluoroethylene (PTFE) and encapsulate the thorium oxide particles. The method 200 also comprising cooling the sintered tape at a controlled rate to prevent crack formation and maintain the integrity of the membrane structure.
