Lithupa tsa PTFE TEFLON
Thepa ea PTFE (e tsejoang ka lik'hemik'hale e le Polytetrafluoroethylene, e tsejoang ka puo ea khale e le Teflon) ke fluoropolymer ea semicrystalline e nang le litšobotsi tse ngata tse ikhethang. Fluoropolymer ena e na le botsitso bo phahameng ba mocheso le khanyetso ea lik'hemik'hale, hammoho le ntlha e phahameng ea ho qhibiliha (-200 ho isa ho +260°C, nako e khuts'oane ho fihlela ho 300°C). Ho phaella moo, lihlahisoa tsa PTFE li na le litšobotsi tse ntle tsa ho thella, khanyetso e ntle ea motlakase le bokaholimo bo sa khomareleng. Leha ho le joalo, sena se fapane le matla a sona a tlase a mechini, le matla a khoheli a phahameng a ikhethang ha a bapisoa le polasetiki e meng. E le ho ntlafatsa litšobotsi tsa mechini, polasetiki ea PTFE e ka matlafatsoa ka lintho tse ling tse kang faeba ea khalase, khabone kapa boronse. Ka lebaka la sebopeho sa eona, Polytetrafluoroethylene hangata e etsoa lihlahisoa tse felileng hanyane ho sebelisoa mokhoa oa ho hatella ebe e etsoa ka lisebelisoa tsa ho seha/ho etsa mechini.

Letlapa le bōpiloeng la PTFE / Poleiti ea Teflon
Leqephe la polytetrafluoroethylene (Leqephe la PTFE) ka ho polarisa polymerization ea ho emisoa ha PTFE resin molding. E na le khanyetso e ntle ka ho fetisisa ea lik'hemik'hale lipolasetiking tse tsejoang 'me ha e tsofale. E na le coefficient e ntle ka ho fetisisa ea khohlano linthong tse tiileng tse tsejoang 'me e ka sebelisoa ho tloha -180 ℃ ho isa ho +260 ℃ ntle le mojaro.

LEQEPHE LE TIILENG LA PTFE (LEQEPHE LA TEFLON)
Leqephe la PTFEe fumaneha ka boholo le botenya bo fapaneng ho tloha ho 1 ho isa ho 150 mm. Bophara ho tloha ho 100mm ho isa ho 2730mm, Filimi e tlositsoeng e tlositsoe ho tloha libolokong tse kholo tsa PTFE (tse chitja). Leqephe la PTFE le bōpiloeng le sebelisoa ka mokhoa oa ho bopa ho fumana botenya bo teteaneng.
