Thepa ea lifilimi tsa PTFE

Filimi ea PTFE e ka fihla tekanyo ea B1 ea ts'ireletso ea mollo ea DIN4012, mocheso o qhibilihang o ka fihla ho 200 ℃, 'me ha ho bonolo ho tšoara mollo.Boima bo bobebe, ductility e ntle, matla a phahameng a hatellang, ha ho bonolo ho tabola.Bophelo bo bolelele ba ts'ebeletso, lilemo tse ka tlase ho 30, thepa e tala e khotsofatsang bakeng sa meaho ea marulelo a ntšitsoeng habeli.Hobane filimi ea PTFE e tiisa ketane ea sebopeho sa limolek'hule ka liathomo tsa fluorine, bokhoni ba eona ba ho monya lintho tse ling tsa lik'hemik'hale bo fokola haholo.Lefatšeng la macro, bokaholimo ba filimi ea PTFE e ka bang 185N/M, thepa e tala e tlase, 'me ha e khomarele.

Ka hona, lifilimi tsa PTFE haholo-holo li bonts'a thepa e ntle ea ho itlhoekisa le ho hanyetsa metsi.Filimi ea Teflon ke thepa e tala ea fiber ea khalase e koahetsoeng ke Teflon.PTFE e bonolo haholo ha e le boemong bo tiileng.Ho roala ho hloka ho qhibiliha ebe ho sebelisoa fiberglass.Mocheso oa ho qhibiliha o ka holimo ho 400 ℃, 'me maqhubu a ho roala a hloka makhetlo a ka bang 10.Sehokelong sena, fiber ea khalase e tla fetoha mosehla ka lebaka la mocheso o phahameng, 'me hangata ho roala, ho ba boima le ho feta' mala.Ka hona, thepa ea filimi ea PTFE polytetrafluoroethylene e sa tsoa hlahisa 'mala o sootho.Leha ho le joalo, thepa ea filimi ea PTFE polytetrafluoroethylene e ka sila le ho monya mahlaseli a ultraviolet ho tsoa mahlaseli a letsatsi.

Filimi ea Teflon ha e khone ho khomarela.Ho tloha tlhahlobo ea thepa ea eona ea 'mele, ho na le mabaka a latelang a bohlokoa: bokaholimo bo tlase, boholo ba likaroloana tse kholo, tlhahlobo e ntle ea botsitso ba lik'hemik'hale, sebopeho se lumellanang haholo sa filimi ea polytetrafluoroethylene, le boleng bo tlase ba SP ba parameter ea solubility ea filimi ea polytetrafluoroethylene.Bokaholimo bo tlase, 'me tšehetso ea holim'a ntlha ea bohlokoa ka kakaretso ha e kholo.PTFE e na le tsitsipano ea pele ea sefahleho ea likhato tse 118, tsitsipano e ka morao ea sefahleho ea likhato tse 91, le tsitsipano ea sefahleho ea likhato tse 104.Lisebelisoa tsohle tse tala li kholo 'me tsitsipano ea sefahleho e phahame.Lethathamo la lubrication le lenyenyane, ke hore, ho se mamelle hantle le sekhomaretsi se sa lekaneng.Filimi ea polasetiki ea Teflon e metsi, kahoo ha ho na ho khomarela hantle ho boholo ba lijo-thollo tsa Teflon, botsitso bo botle ba lik'hemik'hale, ho ruruha ha teflon le ho qhibiliha hohle ho feta li-polymers tsa crystalline tse ke keng tsa koaheloa holim'a filimi ea polasetiki ea Teflon e thata ea polymer macromolecular liketane holim'a metsi.
