Filimka PTFE wuxuu gaari karaa heerka DIN4012 ee ilaalinta dabka ee heerka B1, heerkulku wuxuu gaari karaa 200 ℃, mana fududa in dab la qabsado.Miisaanka fudud, ductility wanaagsan, xoog cadaadis sare, ma fududa in la jeexjeexo.Nolol adeeg oo dheer, in ka yar 30 sano, walxo ceeriin ah oo lagu qanco oo loogu talagalay dhismayaasha saqafka laga saari karo ee laba-lakab ah.Sababtoo ah filimka PTFE wuxuu xiraa silsiladda qaab dhismeedka molecular by atamka fluorine, awoodda ay u leedahay in ay nuugaan walxaha kale ee kiimikaad aad bay u liidataa.Dunida macro, dusha sare ee filimka PTFE wuxuu ku saabsan yahay 185N / M, alaabta ceeriin waa yar tahay, mana aha mid dhejis ah.
Sidaa darteed, filimada PTFE waxay inta badan muujiyaan guryaha is-nadiifinta wanaagsan iyo iska caabbinta biyaha.Filimka Teflon waa alaabta ceeriin ee fiber galaas-dahaarka leh ee Teflon.PTFE waa mid aad u jilicsan marka lagu jiro xaalad adag.Dahaarka wuxuu u baahan yahay in la dhalaaliyo ka dibna lagu dhejiyo fiberglass.Heerkulka dhalaalka ayaa ka sarreeya 400 ℃, iyo inta jeer ee daahan waxay u baahan tahay 10 jeer.Xiriirintan, fiber-ka muraayadda ayaa isu rogi doona huruud sababtoo ah heerkulka sare, iyo inta badan ee daahan, midabku wuu culus yahay.Sidaa darteed, walxaha filimka PTFE polytetrafluoroethylene ayaa soo saaray midab bunni ah.Si kastaba ha noqotee, walxaha filimka PTFE polytetrafluoroethylene waxay dheefshiidi karaan oo nuugi karaan fallaadhaha ultraviolet ee iftiinka qorraxda.
Filimka Teflon laguma dhejin karo.Laga soo bilaabo falanqaynta hantideeda jireed, waxaa jira sababahan muhiimka ah ee soo socda: dusha hoose ee hoose, xajmiga qaybta weyn, falanqaynta xasiloonida kiimikada wanaagsan, qaab dhismeedka sare ee filimka polytetrafluoroethylene, iyo qiimaha hoose ee SP ee cabbirka milanka ee filimka polytetrafluoroethylene.Dusha sare waa hooseeyaa, taageerada dusha sare ee meesha muhiimka ah guud ahaan ma badna.PTFE waxa ay leedahay xiisad hore oo dhexda ah oo ah 118 darajo, xaga danbe ee xiisada dhexda ee 91 darajo, iyo xiisad ka dhexaysa 104 darajo.Dhammaan alaabta ceeriin waa weyn yihiin, xiisadda wejiguna waa sarraysaa.Kala duwanaanshaha sifaynta waa yar yahay, tusaale ahaan ku dheggan liidata iyo koollada oo aan ku filnayn.Filimka caagga ah ee qoyan, sidaas darteed ma jirto adhesion wanaagsan oo ku saabsan cabbirka hadhuudhka Teflon, xasilloonida kiimikada gorfaynta wanaagsan, bararka teflon iyo kala dirida dhammaan polymers crystalline laguma dahaadhi karo filimka caagga ah ee Teflon adag silsiladaha macromolecular polymer ee dusha sare.
