Intambo ye-Teflon enokushisa okuphezulu yenziwe nge-polytetrafluoroethylene, eyaziwa kakhulu ngokuthi ipulasitiki ye-fluorine, efakwe uthayela futhi igoqwe ngama-conductor ensimbi. Ngoba i-teflon ine: ukungavimbi, ukumelana nokushisa, ukushelela, ukumelana nomswakama, ukumelana nokuguguleka, ukumelana nokugqwala nezinye izici. Kodwa-ke, ukumelana nokushisa kwekhebula le-teflon kanye nezinto zokukhipha umsebenzi ngaphandle kunomehluko othile.
Cishe kunezinhlobo ezintathu ze-PTFE ezilandelayo: Izembozo ze-PTFE ezinganamatheli zingasetshenziswa njalo ku-260 ° C, ngokushisa okuphezulu okungu-290-300 ° C, i-coefficient ephansi kakhulu yokungqubuzana, ukumelana okuhle kokuguguleka kanye nokuqina kwamakhemikhali okuhle kakhulu.
I-FEP: I-FEP (i-fluorinated ethylene propylene copolymer) enganamatheli yakhiwa ukugeleza kokuncibilika ngesikhathi sokubhaka, okunokuqina okuhle kwamakhemikhali kanye nezici ezinhle kakhulu zokunganamatheli. Izinga lokushisa eliphezulu lokusetshenziswa lingu-200℃.
I-PFA: Njenge-FEP, izembozo ezinganamatheli ze-PFA (perfluoroalkyl) zihlanganiswa ukuze zenze amafilimu anezimbobo ngesikhathi sokubhaka. I-PFA inenzuzo yokushisa okuphezulu okuqhubekayo okungu-260℃, ukuqina okuqinile, okufanelekela kakhulu ukusetshenziswa kokumelana nokunamathela okushisa okuphezulu kanye nokumelana namakhemikhali.
Ukusebenza kwentambo ye-Teflon enokushisa okuphezulu kanye nokusetshenziswa kwayo.
Izakhiwo: ukumelana okuhle kakhulu nokugqwala, cishe okungancibiliki kunoma yisiphi isinyibilikisi sezinto eziphilayo, kungamelana namafutha, i-asidi enamandla, i-alkali enamandla, i-oxidant enamandla, njll. I-voltage ephezulu, ukulahlekelwa okuphansi kwemvamisa ephezulu, akukho ukumuncwa komswakama, ukumelana okuphezulu kokushisa; Inokumelana okuhle kakhulu nomlilo, ukumelana nokuguga kanye nokuphila isikhathi eside.
Isicelo: embonini ye-elekthronikhi, ingasetshenziselwa ucingo lokunciphisa izinga lokushisa, ucingo lokumelana nokushisa okuphansi, ucingo lokushisa lokushisa eliphezulu, ucingo lokumelana nokuguga kanye nocingo olugcina ilangabi; Embonini yemishini yasekhaya, ingasetshenziselwa ukuxhuma kwangaphakathi kwe-air conditioner, i-microwave oven, ikhabhinethi yokubulala amagciwane kagesi, isitofu sikagesi selayisi, ibhodlela le-thermos kagesi, isifudumezi sikagesi, i-oven kagesi, ipani lokuthosa likagesi, izibani nezibani.
