Polytetrafluoroethylene (PTFE) ndi fluoropolymer yopanga ya tetrafluoroethylene yomwe ili ndi ntchito zambiri.Dzina lodziwika bwino la mtundu waPTFE- zochokera…
PolyTetraFluoroEthylene ndi polima wopangidwa ndi fluorocarbon ndipo nthawi zambiri amafupikitsidwa PTFE.Opanga ena angapo amapanga mitundu yawoyawo ya PTFE yomwe ingagwiritsidwe ntchito ngati zolowa m'malo.Banja la fluoroplastic limeneli limapereka kukana kwa mankhwala, kutsika komanso kutentha kwakukulu, kukana kutentha kwa nyengo, kukangana kochepa, kutsekemera kwamagetsi ndi kutentha, ndi "kuterera".(onaninso polymer® PTFE ndipolima® FEP & PFA Specifications ) Makina a PTFE ndi otsika poyerekeza ndi mapulasitiki ena, koma katundu wake amakhalabe pamlingo wothandiza pa kutentha kwakukulu kwa -100 ° F mpaka + 400 ° F (-73 ° C mpaka 204 ° C) .Makina amakina nthawi zambiri amawonjezeredwa powonjezera zodzaza (onani ndime pansipa).Ili ndi mphamvu zabwino kwambiri zotenthetsera kutentha ndi magetsi komanso kugundana kochepa.PTFE ndi wandiweyani kwambiri ndipo sangathe kusungunuka kukonzedwa - ayenera wothinikizidwa ndi sintered kupanga zothandiza akalumikidzidwa.
Makina a PTFE amatha kukulitsidwa powonjezera zodzaza monga magalasi, kaboni, graphite, molybdenum disulphide, ndi bronze.Nthawi zambiri, ma PTFE odzazidwa amasunga mawonekedwe awo abwino kwambiri amankhwala komanso kutentha kwambiri, pomwe zodzaza zimawonjezera mphamvu zamakina, kukhazikika, komanso kukana kuvala.Makhalidwe a 25% odzaza magalasi ndi 25% odzazidwa ndi carbon PTFE giredi akuwonetsedwa pansipa kuti afananize.Pali mitundu yambiri yazinthu zodzazidwa ndi PTFE - zambiri zomwe sizingatchulidwe apa.
TYPICAL PROPERTIES of PTFE
ZINDIKIRANI: Zomwe zili m'nkhaniyi ndi zamtengo wapatali zomwe zimangogwiritsidwa ntchito komanso kufananitsa.Sayenera kugwiritsidwa ntchito ngati maziko a kamangidwe kake kapena kuwongolera khalidwe.Lumikizanani nafe kuti mupeze mapepala athunthu azinthu zopangidwa ndi opanga.Miyezo yonse pa 73°F (23°C) pokhapokha zitadziwika.
