Menene PTFE?
Polytetrafluoroethylene (PTFE) wani nau'i ne na polymer wanda aka yi da tetrafluoroethylene a matsayin monomer.Yana da zafi mai kyau da juriya na sanyi kuma ana iya amfani dashi na dogon lokaci a rage 180 ~ 260 º C. Wannan abu yana da halayen juriya na acid, juriya na alkali da juriya ga nau'o'in kwayoyin halitta daban-daban, kuma kusan kusan ba zai iya narkewa a cikin dukkanin kaushi.A lokaci guda, polytetrafluoroethylene yana da halaye na tsayin daka na zafin jiki, kuma ƙarancin juzu'in sa yana da ƙasa sosai, don haka ana iya amfani dashi don lubrication, kuma ya zama madaidaicin shafi don sauƙin tsaftacewa na ciki na bututun ruwa.PTFE yana nufin ƙari na rufin PTFE a cikin haɗin gwiwa na roba na EPDM na yau da kullun, wanda yafi fari.
Matsayin PTFE
PTFE iya yadda ya kamata kare roba gidajen abinci daga karfi acid, karfi alkali ko high zafin jiki mai da sauran kafofin watsa labarai lalata.

- PTFE yana da juriya ga babban zafin jiki da lalata, yana da ingantaccen rufin lantarki, juriya na tsufa, ƙarancin shayar ruwa, da kyakkyawan aikin lubrication na kai.Yana da foda mai lubricating na duniya wanda ya dace da kafofin watsa labaru daban-daban, kuma za'a iya rufe shi da sauri don samar da fim mai bushe, wanda za'a iya amfani dashi a maimakon graphite, molybdenum da sauran kayan shafawa na inorganic.Wani wakili ne na saki wanda ya dace da thermoplastic da thermosetting polymers, tare da kyakkyawan ƙarfin ɗauka.Ana amfani dashi sosai a masana'antar elastomer da roba da kuma rigakafin lalata.
- A matsayin mai filler ga resin epoxy, yana iya inganta juriyar abrasion, juriya mai zafi da juriya na lalata manne epoxy.
- An fi amfani dashi azaman ɗaure da filler na foda.
Abubuwan da aka bayar na PTFE
- High zafin jiki juriya - aiki zafin jiki har zuwa 250 ℃
- Low zafin jiki juriya - mai kyau inji taurin;Ko da yawan zafin jiki ya ragu zuwa -196 ℃, ana iya kiyaye elongation na 5%.
- Juriya na lalata - don yawancin sinadarai da kaushi, ba shi da ƙarfi kuma yana jurewa ga acid mai ƙarfi da alkalis, ruwa da sauran kaushi na halitta.
- Juyin yanayi - yana da mafi kyawun rayuwar tsufa na robobi.
- Babban lubrication shine mafi ƙarancin juzu'i a tsakanin ingantaccen kayan aiki.
- Rashin mannewa - shine mafi ƙarancin tashin hankali a cikin kayan aiki mai ƙarfi kuma baya bin kowane abu.
- Ba mai guba ba - Yana da inertia na ilimin lissafi, kuma ba shi da mummunan halayen bayan dasawa na dogon lokaci a matsayin tasoshin jini na wucin gadi da gabobin.
- Rufin lantarki - zai iya jure wa babban ƙarfin lantarki na 1500 V.
