Abubuwan Fina-finan PTFE

Fim ɗin PTFE zai iya kaiwa matakin DIN4012 kariya ta wuta daidaitaccen matakin B1, zafin jiki na narkewa zai iya kaiwa 200 ℃, kuma ba shi da sauƙin kama wuta.Light nauyi, mai kyau ductility, high compressive ƙarfi, ba sauki yaga.Rayuwar sabis mai tsayi, ƙasa da shekaru 30, ingantaccen albarkatun ƙasa don gine-ginen rufin mai cirewa mai Layer biyu.Saboda fim din PTFE yana rufe sarkar tsarin kwayoyin halitta ta kwayoyin fluorine, ikonsa na sha wasu sinadarai yana da rauni sosai.A cikin duniyar macro, fuskar fim ɗin PTFE yana kusan 185N / M, albarkatun ƙasa ba su da ƙarfi, kuma ba su da ƙarfi.

Don haka, fina-finan PTFE galibi suna nuna kyawawan kaddarorin tsaftace kai da juriya na ruwa.Teflon fim ne albarkatun kasa na Teflon-rufi gilashi fiber.PTFE yana da malleable sosai a cikin m yanayi.Rufin yana buƙatar narke sannan a yi amfani da fiberglass.The narkewa zafin jiki ne sama da 400 ℃, da shafi mita bukatar game da 10 sau.A cikin wannan hanyar haɗin gwiwa, gilashin gilashin za su juya launin rawaya saboda yawan zafin jiki, kuma mafi yawan abin rufewa, nauyin launi.Saboda haka, PTFE polytetrafluoroethylene fim abu ya samar da launin ruwan kasa kawai.Duk da haka, PTFE polytetrafluoroethylene film abu iya narke da kuma sha ultraviolet haskoki daga hasken rana.

Ba za a iya manna fim ɗin Teflon ba.Daga nazarin abubuwan da ke cikin jiki, akwai dalilai masu mahimmanci masu zuwa: ƙananan ƙasa, girman girman ƙwayar ƙwayar cuta, kyakkyawan bincike na kwanciyar hankali na sinadarai, tsari mai mahimmanci na fim din polytetrafluoroethylene, da ƙananan darajar SP na solubility siga na fim din polytetrafluoroethylene.Ƙarƙashin ƙasa yana da ƙasa, kuma goyon bayan saman a mahimmin mahimmanci ba shi da girma.PTFE yana da tashin hankali na tsaka-tsakin fuska na digiri 118, tashin hankali na gaba na digiri 91, da tashin hankali na 104 digiri.Duk albarkatun ƙasa suna da girma kuma tashin hankali tsakanin fuska yana da girma.Kewayon man shafawa ƙanana ne, watau ƙarancin mannewa da rashin isasshen mannewa.Rigar Teflon filastik fim, don haka babu mai kyau mannewa zuwa Teflon hatsi size, mai kyau analytical sinadaran kwanciyar hankali, teflon kumburi da dissolving duk fiye da crystalline polymers ba za a iya mai rufi a kan Teflon filastik fim wuya polymer macromolecular sarƙoƙi a kan surface.
