Ubwino wa PTFE

Pali zabwino zisanu ndi zitatu za PTFE:
Mmodzi: PTFE ali ndi katundu kutentha kukana mkulu, ntchito yake kutentha kufika 250 ℃, pamene ambiri pulasitiki kutentha kufika 100 ℃, pulasitiki adzasungunuka palokha, koma pamene tetrafluoroethylene kufika 250 ℃, akhoza kusunga dongosolo lonse. Sichisintha, ndipo ngakhale kutentha kukafika 300 ° C nthawi yomweyo, sipadzakhala kusintha kwa thupi.
Awiri: PTFE ilinso ndi katundu wosiyana, ndiko kuti, kutentha kochepa, 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 sichitha kuyaka, ndipo imakhala yokhazikika kwambiri ku mpweya ndi kuwala kwa ultraviolet, choncho imakhala ndi moyo wokalamba wabwino kwambiri mu mapulasitiki.
Chasanu: PTFE ali mkulu mafuta katundu, ndi PTFE ndi yosalala kuti sangathe ngakhale kuyerekeza ndi ayezi, choncho ali otsika mikangano koyenera pakati zipangizo olimba.
Chachisanu ndi chimodzi: PTFE ili ndi katundu wosamatira.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 matenda, monga mitsempha yamagazi, ma extracorporeal circulators, 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.
