Ucingo lweTeflon olunobushushu obuphezulu lwenziwe ngepolytetrafluoroethylene, eyaziwa ngokuba yiplastiki yefluorine, egqunywe nge-insulated kwaye isongelwe kwiikhontraktha zesinyithi. Kuba iTeflon ine: ukungangqinelani nobushushu, ukutyibilika, ukumelana nokufuma, ukumelana nokuguguleka, ukumelana nokugqwala kunye nezinye iimpawu. Nangona kunjalo, ukumelana nobushushu bekhebula leTeflon kunye nezinto zokuthumela ngaphandle kunomahluko othile.
Kukho phantse iintlobo ezintathu ze-PTFE ezilandelayo: Iingubo ze-PTFE ezinganamatheliyo zingasetyenziswa rhoqo kwi-260 ° C, kunye nobushushu obuphezulu be-290-300 ° C, i-coefficient ephantsi kakhulu yokungqubana, ukumelana nokuguguleka okuhle kunye nozinzo oluhle kakhulu lweekhemikhali.
I-FEP: I-FEP (i-fluorinated ethylene propylene copolymer) enganamatheliyo yenziwa ngokuhamba kwamanzi okunyibilika ngexesha lokubhaka, okune-chemical stability egqwesileyo kunye neempawu ezibalaseleyo zokunganamatheli. Ubushushu obuphezulu bokusetyenziswa yi-200℃.
I-PFA: Njenge-FEP, ii-PFA (perfluoroalkyl) ezinganamatheliyo zidityaniswa ukwenza iifilimu ezinemingxuma ngexesha lokubhaka. I-PFA inenzuzo yokuba nobushushu obuphezulu obuqhubekayo obuyi-260℃, ukuqina okuqinileyo, ngakumbi ezifanelekileyo kwizicelo zokuthintela ukunamathela kubushushu obuphezulu kunye nokumelana neekhemikhali.
Ukusebenza kwentambo yeTeflon enobushushu obuphezulu kunye nokusetyenziswa kwayo.
Iipropati: ukumelana nokugqwala okugqwesileyo, phantse kunganyibiliki nakweyiphi na i-organic solvent, inokumelana neoyile, i-asidi enamandla, i-alkali enamandla, i-oxidant enamandla, njl. I-voltage ephezulu, ukulahleka okuphantsi kwamaza aphezulu, akukho kufuma, ukumelana nobushushu obuphezulu; Inokumelana okuhle komlilo, ukumelana nokwaluphala kunye nobomi benkonzo ende.
Isicelo: kwishishini le-elektroniki, ingasetyenziselwa ucingo lokubuyisela ubushushu, ucingo lokumelana nobushushu obuphantsi, ucingo lokufudumeza oluphezulu, ucingo lokumelana nokuguga kunye nocingo oluthintela ilangatye; Kwishishini lezixhobo zasekhaya, ingasetyenziselwa ukufakelwa kwangaphakathi kwe-air conditioner, i-oven ye-microwave, ikhabhinethi yokubulala iintsholongwane nge-elektroniki, isitofu serayisi sombane, ibhotile ye-thermos ye-elektroniki, isifudumezi sombane, i-oven yombane, ipani yokuqhotsa ngombane, izibane kunye nezibane.
