Kemiso le ts’ebetso ea boto ea PTFE

Boto ea Polytetrafluoroethylene (eo hape e bitsoang boto ea tetrafluoroethylene, boto ea Teflon, boto ea Teflon) e arotsoe ka mefuta e ‘meli: ho bopa le ho fetoha. E entsoe ka ho pholisa. PTFE retelehela boto e entsoe ka PTFE lehoakhoa ka phehella, sintering le gommage. Lihlahisoa tsa eona li na le ts’ebeliso e fapaneng le thepa e phethahetseng e phethahetseng: ho hanyetsa mocheso o phahameng le o tlase (-192 ℃ -260 ℃), ho hanyetsa ts’enyeho (asiti e matla, alkali e matla, aqua regia, jj.), Ho hanyetsa maemo a leholimo, setlolo, se sa khomaretseng, E seng chefo le litšobotsi tse ling tse ntle haholo.
