I-Teflon yaziwa njenge-polytetrafluoroethylene (isishunqulelo sesiNgesi se-teflon okanye [PTFE, F4]), eyaziwa ngokuba yi-"inkosi yeplastiki", ekwabizwa ngokuba yi "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon".Yikhompawundi ye-polymer eyenziwe nge-tetrafluoroethylene nge-polymerization, kwaye isakhiwo sayo silula njenge--[-cf2-cf2 -]n-.

I-Polytetrafluoroethylene, eyaziwa njenge-non-stick coating okanye kulula ukuyicoca.Esi sixhobo sineempawu zokumelana ne-asidi kunye ne-alkali, ukuxhathisa kwiintlobo ezahlukeneyo ze-solvents eziphilayo, kwaye ziphantse zinganyibiliki kuzo zonke izinyibilikisi.Ngelo xesha, i-polytetrafluoroethylene ineempawu zokumelana nokushisa okuphezulu, i-coefficient yayo ye-friction iphantsi kakhulu, ngoko ingasetyenziselwa ukuthambisa, kodwa ibe yinto efanelekileyo yokugubungela ngokulula ukucoca umaleko wangaphakathi wemibhobho yamanzi.

I-Teflon plating ikakhulu ixhomekeke kuhlobo lwenkqubo ofuna ukumisela indlela yokutshiza.Into ebaluleke kakhulu kukuba iTeflon yokugqoka idinga ukubhaka kumaqondo okushisa aphezulu ngaphambi kokuba isetyenziswe.

Iimpawu zeTeflon:

I-non-adhesive: Phantse zonke izinto azidibanisi kunye ne-teflon coating.

Ukumelana nokushisa okuphantsi: ukuqina kakuhle komatshini;Nokuba iqondo lobushushu liyehla ukuya kwi-196 ° C, ubude be-5% bunokugcinwa.Isathambile kwi-100 degrees.

Ukumelana nobushushu obuphezulu: i-polytetrafluoroethylene yokwambathisa inobushushu obubalaseleyo kunye nokumelana nobushushu obuphantsi.Inokumelana nobushushu obuphezulu ukuya kuma-300 ° C ixesha elifutshane, ngokubanzi ingasetyenziswa ngokuqhubekayo phakathi kwe-240 ° C kunye ne-260 ° C, kwaye inozinzo olubalulekileyo lwe-thermal, inokusebenza kumaqondo obushushu abandayo ngaphandle kwe-embrittlement, kwaye ayinyibiliki kumaqondo aphezulu. .

Ukuthambisa okuphezulu: Yeyona coefficient esezantsi yokukhuhlana kwizinto eziqinileyo.Inowona mlinganiso uphantsi wokukhuhlana (0.04) phakathi kweeplastiki.Ithambile kunomkhenkce.

Ukuxhathisa ukufuma: umphezulu we-PTFE wokugquma awungcoliswanga ngamanzi kunye neoli, kwaye akulula ukunamathela kwisisombululo ngexesha lokusebenza kwemveliso.Ukuba kukho ukungcola okuncinci, kunokususwa ngokusula nje.Ixesha elifutshane lokuphumla ligcina ixesha kwaye liphucula ukusebenza kakuhle.

Ukumelana nokunxiba: Inokumelana nokunxiba okugqwesileyo phantsi komthwalo ophezulu.Ngaphantsi komthwalo othile, uneenzuzo ezimbini zokuxhatshazwa kokugqoka kunye nokungabambeleli.

Ukumelana nomhlwa: i-polytetrafluoroethylene iphantse yakhululeka kuhlaselo lweziyobisi, kwaye inokumelana nazo zonke iiasidi ezomeleleyo (kubandakanya i-aqua aqua), i-oxidants eyomeleleyo, i-oxidants ezomeleleyo, ii-agent zokunciphisa kunye nezinyibilikisi ezahlukeneyo ze-organic ukongeza kwisinyithi esinyibilikisiweyo sealkali, imidiya ye-fluorinated kunye ne-sodium hydroxide ngaphezulu kwe-300 ° C, kunye inokukhusela amalungu kulo naluphi na uhlobo lokubola kweekhemikhali.

Ukumelana nokuguga: ukumelana nemitha kunye nokunyanzeliswa okuphantsi: ukubonakaliswa kwexesha elide emoyeni, umphezulu kunye nokusebenza kuhlala kungatshintshi.

Ukungatshi: isalathisi somda we-oxygen singaphantsi kwama-90.

Ukumelana ne-Acid kunye ne-alkali: i-insoluble kwi-acids eqinile, iziseko ezomeleleyo kunye ne-solvents eziphilayo (kubandakanywa ne-magic acid, oko kukuthi, i-fluoroantimonic acid).

Ukunganyangeki kwi-oxidation: Ukumelana nomhlwa zii-oxidants ezinamandla.

I-Insulation: Ukusebenza kombane okugqwesileyo, yeyona nto ifanelekileyo ye-C-class insulation material, umaleko wephephandaba elishinyeneyo unokuthintela uxinzelelo oluphezulu lwe-1500V.I-insulation yayo yombane ayichaphazeli ukushisa.I-dielectric constant kunye nelahleko ye-dielectric iphantsi kwi-wide frequency range, kwaye i-voltage yokuphuka, i-resistivity ye-volume kunye ne-arc resistance iphezulu.

I-Acid-base: ingathathi hlangothi.
