Ke phello efe ea elasticity ea PTFE polytetrafluoroethylene board?
PTFE polytetrafluoroethylene board e na le khanyetso e ntle ea arc. PTFE e na le botsitso bo botle ba lik’hemik’hale ‘me ha e nyenyefatsoe ke lik’hemik’hale leha e le life. Lik’hemik’hale tse ngata tse senyang haholo le tse nang le oxidizing ha li na phello e fokolang, kahoo li bitsoa morena oa polasetiki. Litšobotsi tsa ts’ebetso ea thepa ea ‘mele le ea mochini, PTFE e na le sekhahla se phahameng se lekanyelitsoeng mme ha e monye metsi. E thata ebile e inela. The friction factor e nyane haholo mme ts’ebetso ea lubrication e ntle haholo. The static khohlano ntlha ya PTFE ke nyenyane ho feta dynamic khohlano ntlha, ‘me khohlano ntlha lula hoo e ka bang e sa fetohe ho tloha Ultra-tlase mocheso ho ntlha melting. Leha ho le joalo, PTFE e na le boima bo tlase mme e apesoa habonolo ke lisebelisoa tse ling. Haeba filimi ea PTFE e ka thehoa holim’a sekoti, ho apara ha PTFE ho ka fokotsoa haholo. Ho tsitsa ha mocheso oa PTFE ho hlahelletse haholo ho lipolasetiki tsa boenjiniere. Ho tloha ho 200 ° C ho ea sebakeng se qhibilihang, sekhahla sa ho bola se lieha haholo, ‘me palo ea ho bola le eona e nyane haholo. Ho futhumala ka 200 ° C ka khoeli e le ‘ngoe, chelete ea ho bola e ka tlase ho milione e le’ ngoe, e ke keng ea hlokomolohuoa. PTFE ha e brittle ho -250°C.
