Teflon ephezulu esebenzayo yokwaleka ezizodwaptfenjengesiseko se-resin yokugquma i-fluorine, igama lesiNgesi leTeflon, ngenxa yokubiza amagama, ngokuqhelekileyo kwaziwa ngokuba yiTeflon, iTeflon, iTeflon, iTeflon njalo njalo (konke ukuguqulelwa kweTeflon).

I-Teflon ihlulwe ibe yi-PTFE, FEP, PFA, ETFE iindidi ezininzi ezisisiseko: TEflon PTFE: PTFE (polytetrafluoron) i-non-stick coating ingasetyenziswa ngokuqhubekayo kwi-260 deG C, kunye nobushushu obuphezulu bokusetyenziswa kwe-290-300 DEG C, ukungqubuzana okuphantsi kakhulu. i-coefficient, ukumelana nokunxiba kakuhle kunye nokuzinza kweekhemikhali okugqwesileyo. I-Teflon FEP: I-FEP (i-ethylene propylene copolymer ene-fluorinated) i-non-stick copolymer yokwambathisa iyanyibilika ngexesha lokubhaka ukuze yenze ifilimu engeyiyo i-porous, kunye nokuzinza kweekhemikhali okugqwesileyo, iipropati ezigqwesileyo ezingenakukhuni, ubushushu obuphezulu bokusebenza ngu-200 ℃. I-Teflon PFA: I-PFA (i-perfluoroalkyl) i-non-stick coatings, njenge-FEP, inyibilika ngexesha lokubhaka ukwenza ifilimu e-porous. Izibonelelo ze-PFA ziphezulu ngokuqhubekayo ubushushu bokusetyenziswa kwe-260 ℃, ukuqina olomeleleyo, ngakumbi kulungele ukusetyenziswa kobushushu obuphezulu phantsi kwesiseko sokuchasa intonga kunye nokumelana nemichiza kwindawo yokusetyenziswa. I-Teflon ETFE: I-ETFE yi-copolymer ye-ethylene kunye ne-tetrafluoroethylene. I-resin yeyona fluoropolymer yomelele, yenza i-coating ehlala ixesha elide kunye nokusebenza okugqwesileyo kokumelana neekhemikhali kwi-150 ° C.

Emva kokugqunywa ngeTeflon, inezi mpawu zilandelayo:

I-1, i-non-viscosity: phantse zonke izinto azixhunyiwe kunye nefilimu ye-teflon. Iinwebu ezibhityileyo kakhulu zikwabonisa iimpawu ezibalaseleyo zokungabambeleli.

I-2, ukumelana nobushushu: Ifilimu yeTeflon inokumelana nobushushu obubalaseleyo kunye nokumelana nobushushu obuphantsi. Ixesha elifutshane linokumelana nobushushu obuphezulu ukuya kwi-300 ℃, ngokubanzi phakathi kwe-240℃ ~ 260 ℃ ingasetyenziswa ngokuqhubekayo, ngobushushu obucacileyo abunacwangco, inokusebenza kwiqondo lomkhenkce ngaphandle kwe-embrittlement, ayinyibiliki kubushushu obuphezulu.

I-3, i-sliding: Ifilimu yeTeflon ine-coefficient ephantsi ye-friction. Xa isilayidi somthwalo, i-coefficient ye-friction iyatshintsha, kodwa ixabiso liphakathi kwe-0.05 kunye ne-0.15 kuphela.

I-4, ukuxhathisa umswakama: umphezulu wefilimu ye-teflon ayinamathele kumanzi kunye neoli, ulawulo lwemveliso alulula ukunamathela kwisisombululo, njengobumdaka obuncinci, ukusula okulula kunokususwa. Ixesha elifutshane lokuphumla, gcina ixesha kunye nokuphucula ukusebenza kakuhle.

I-5, ukuxhathisa ukunxiba: phantsi komthwalo ophezulu, kunye nomsebenzi obalaseleyo wokuxhathisa. Ngaphantsi komthwalo othile, uneenzuzo ezimbini zokuxhatshazwa kokugqoka kunye nokungabambeleli.

6. I-Corrosion resistance: I-Teflon iphantse ixhathise kumhlwa kwaye inokukhusela amalungu kulo naluphi na uhlobo lokhukuliseko lwekhemikhali.
