Ubwino wa PTFE

Pali zabwino zisanu ndi zitatu za PTFE:
Mmodzi: PTFE ali ndi katundu kukana kutentha, ntchito yake kutentha kufika 250 ℃, pamene ambiri pulasitiki kutentha kufika 100 ℃, pulasitiki adzasungunuka palokha, koma pamene tetrafluoroethylene kufika 250 ℃, akhoza kusunga dongosolo lonse. Sichimasintha, ndipo ngakhale kutentha kukafika 300 ° C nthawi yomweyo, sipadzakhala kusintha kwa thupi.
Awiri: PTFE ilinso ndi katundu wosiyana, ndiko kuti, kutentha kwapansi, pamene kutentha kumatsika mpaka -190 ° C, ikhoza kukhalabe ndi 5% elongation.
Chachitatu: PTFE ili ndi zinthu zolimbana ndi dzimbiri.Kwa mankhwala ambiri ndi zosungunulira, zimasonyeza inertness ndipo akhoza kupirira zidulo amphamvu ndi alkalis, madzi ndi zosiyanasiyana zosungunulira organic.
Chachinayi: PTFE ili ndi mphamvu zoletsa nyengo.PTFE sichimamwa chinyezi ndipo sichiyaka, ndipo imakhala yokhazikika kwambiri ku mpweya ndi kuwala kwa ultraviolet, choncho imakhala ndi moyo wabwino kwambiri wokalamba mu mapulasitiki.
Chachisanu: PTFE ili ndi mafuta odzola kwambiri, ndipo PTFE ndi yosalala kwambiri moti sichingafanane ndi ayezi, choncho imakhala ndi coefficient yotsika kwambiri pakati pa zipangizo zolimba.
Chachisanu ndi chimodzi: PTFE ili ndi katundu wosamata.Chifukwa mphamvu ya intermolecular ya carbon-carbon chain ndi yochepa kwambiri, siimamatira kuzinthu zilizonse.
Zisanu ndi ziwiri: PTFE imakhala ndi zinthu zopanda poizoni, choncho imagwiritsidwa ntchito pochiza, monga mitsempha yamagazi, ma circulators a extracorporeal, rhinoplasty, etc., monga chiwalo cha kuikidwa kwa nthawi yaitali m'thupi popanda zotsatirapo zoipa.
Eyiti: PTFE ili ndi mphamvu yotchinjiriza magetsi, imatha kukana 1500 volts yamagetsi apamwamba.
