Khoele ea ho Roka ea PTFE e nang le Ts'ebetso e Ntle ho Maemo a Tshebetso a Thata

PTFE ke fluoropolymer ea maiketsetso e tsebahalang ka ho hanyetsa lik'hemik'hale tse ikhethang, ho hanyetsa mocheso o phahameng, le khohlano e tlase ea khohlano. Lintho tsena li etsa hore e be thepa e loketseng bakeng sa khoele ea ho roka e sebelisoang ka mekotleng ea sefe. Khoele ea ho roka ea PTFE e hanana le lik'hemik'hale tse ngata, ho kenyelletsa le li-acids, bases, le solvents, e etsang hore e loketse ho sebelisoa libakeng tse thata. Ho feta moo, PTFE e ka mamella mocheso ho fihlela ho 260°C, e leng holimo ho feta mefuta e meng e mengata ea likhoele.

Molemo o mong oa khoele ea ho roka ea PTFE ke coefficient ea eona e tlase ea likhohlano. Thepa ena e lumella khoele hore e thelle habonolo ka har'a lesela, e fokotsa kotsi ea ho robeha ha khoele le ho ntlafatsa matla a kakaretso a ho roka. Coefficient e tlase ea khohlano e boetse e etsa hore khoele ea ho roka ea PTFE e loketse ho sebelisoa mechineng ea ho roka ka lebelo le phahameng, e atisang ho sebelisoa ha ho etsoa mekotla ea filthara.

Khoele ea ho roka ea PTFE e boetse e hanana le mahlaseli a UV, e etsang hore e loketse lits'ebetso tsa kantle. Khoele ha e fokotsehe kapa ea fetoha brittle ha e pepesetsoa khanya ea letsatsi, e leng se tiisang hore mokotla oa sefa o phela nako e telele. Ho feta moo, khoele ea ho roka ea PTFE ha e na chefo ebile ha e lokolle lintho tse kotsi, e etsa hore e sireletsehe bakeng sa tšebeliso ea lijo le litlhare.

Ha re bua ka kakaretso, khoele ea ho roka ea PTFE ke khetho e ntle haholo bakeng sa ho roka mekotla ea sefa ka lebaka la ho hanyetsa lik'hemik'hale tse ikhethang, ho hanyetsa mocheso o phahameng, khohlano e tlase, le ho hanyetsa mahlaseli a UV. Lintho tsena li etsa hore khoele ea ho roka ea PTFE e loketse ho sebelisoa libakeng tse thata le lits'ebetsong tsa kantle. Ho feta moo, khoele e bolokehile hore e ka sebelisoa lijong le lits'ebetsong tsa meriana, e etsa hore e be khetho e fapaneng bakeng sa liindasteri tse fapaneng.
