Mukudziwa chiyani za PTFE?

PTFE ndi chiyani?

Polytetrafluoroethylene (PTFE) ndi mtundu wa polima wopangidwa ndi tetrafluoroethylene ngati monomer. Ili ndi kutentha kwambiri komanso kukana kuzizira ndipo imatha kugwiritsidwa ntchito kwa nthawi yayitali osakwana 180 ~ 260 º C. Nkhaniyi ili ndi mawonekedwe a kukana kwa asidi, kukana kwa alkali ndi kukana zosungunulira zosiyanasiyana za organic, ndipo pafupifupi insoluble mu zosungunulira zonse. Nthawi yomweyo, polytetrafluoroethylene ali ndi makhalidwe a kutentha kukana, ndi mikangano coefficient ndi otsika kwambiri, choncho angagwiritsidwe ntchito kondomu, komanso kukhala ❖ kuyanika abwino kuyeretsa mosavuta wosanjikiza wa mkati mipope madzi. PTFE amatanthauza kuwonjezera kwa PTFE zokutira akalowa mkati wamba EPDM mphira olowa, amene makamaka woyera.

Udindo wa PTFE

PTFE imatha kuteteza mafupa a mphira ku asidi amphamvu, alkali wamphamvu kapena mafuta otenthetsera komanso kuwononga zina.

Cholinga

• Amagwiritsidwa ntchito m'makampani amagetsi komanso ngati wosanjikiza, zosagwirizana ndi dzimbiri komanso zosavala zamagetsi ndi mizere yamagetsi muzamlengalenga, ndege, zamagetsi, zida, makompyuta ndi mafakitale ena. Angagwiritsidwe ntchito kupanga mafilimu, mapepala chubu, ndodo, mayendedwe, gaskets, mavavu, mipope mankhwala, zovekera chitoliro, zipangizo chidebe linings, etc.
• Amagwiritsidwa ntchito m'minda ya zida zamagetsi, makampani mankhwala, ndege, makina ndi madera ena m'malo quartz glassware kwa kopitilira muyeso-woyera mankhwala kusanthula ndi kusunga zidulo zosiyanasiyana, alkali ndi zosungunulira organic m'madera a atomiki mphamvu, mankhwala, semiconductor. ndi mafakitale ena. Itha kupangidwa kukhala zida zamagetsi zotchinjiriza kwambiri, mawaya okwera pafupipafupi ndi zingwe zamagetsi, ziwiya zamagetsi zosagwirizana ndi dzimbiri, mapaipi amafuta osagwira kutentha kwambiri, ziwalo zopangira, etc. Itha kugwiritsidwa ntchito ngati zowonjezera mapulasitiki, mphira, zokutira, inki, mafuta opangira mafuta, mafuta, etc.
• PTFE imagonjetsedwa ndi kutentha kwakukulu ndi dzimbiri, imakhala ndi magetsi abwino kwambiri, kukana kukalamba, kuyamwa kwamadzi otsika, komanso ntchito yabwino yodzipaka mafuta. Ndi chilengedwe chonse mafuta ufa oyenera atolankhani zosiyanasiyana, ndipo akhoza mwamsanga TACHIMATA kupanga youma filimu, amene angagwiritsidwe ntchito m'malo graphite, molybdenum ndi mafuta ena inorganic. Ndiwotulutsa woyenerera ma polima a thermoplastic ndi thermosetting, okhala ndi mphamvu yabwino yonyamula. Amagwiritsidwa ntchito kwambiri mumakampani a elastomer ndi labala komanso kupewa dzimbiri.
• Monga chojambulira cha epoxy resin, chimatha kupititsa patsogolo kukana kwa abrasion, kukana kutentha komanso kukana kwa dzimbiri kwa zomatira za epoxy.
• Amagwiritsidwa ntchito makamaka ngati binder ndi filler ya ufa.

Ubwino wa PTFE

• High kutentha kukana - ntchito kutentha kwa 250 ℃
• Kukana kutentha kwapansi - kulimba kwa makina abwino; Ngakhale kutentha kutsika mpaka -196 ℃, elongation ya 5% ikhoza kusungidwa.
• Kulimbana ndi dzimbiri - kwa mankhwala ambiri ndi zosungunulira, ndizopanda mphamvu komanso kusagwirizana ndi ma acid amphamvu ndi alkalis, madzi ndi zosungunulira zosiyanasiyana.
• Kukana kwanyengo - kumakhala ndi moyo wokalamba wabwino kwambiri wa mapulasitiki.
• Kupaka mafuta kwambiri ndiye kugunda kotsika kwambiri pakati pa zinthu zolimba.
• Kusamatira - ndiko kupsinjika kochepa kwapamtunda muzinthu zolimba ndipo sikumamatira kuzinthu zilizonse.
• Non-toxic - Imakhala ndi inertia yakuthupi, ndipo ilibe zovuta pambuyo pa kuikidwa kwa nthawi yayitali ngati mitsempha yamagazi ndi ziwalo.
• Kutsekemera kwamagetsi - kumatha kupirira 1500 V high voltage.
