Ipleyiti yeTetrafluoroethylene yaziwa ngokuba yinkosi yeeplastiki kwintsimi yeeplastiki, kwaye ukusebenza kwayo akubonakali kwiiplastiki eziqhelekileyo, ngoko ke isetyenziswa ngokubanzi kwiindawo ezineemeko ezinzima, ezifana ne-asidi kunye ne-alkali, imithombo yeendaba ezonakalisayo kunye nobushushu obuphezulu.Ke, zeziphi iingenelo zebhodi yePTFE?
Okokuqala, inokumelana nokushisa okuphezulu.Ngokubhekiselele kusetyenziso lwangoku lwezixhobo zephepha le-tetrafluoroethylene, izinto ezikrwada zinokufikelela kuma-232 °C, kwaye nobushushu obuphezulu emva kokubuyela ekhejini linokufikelela malunga ne-150 °C, kwaye ubushushu bokusetyenziswa bubanzi kakhulu.
Iphepha le-PTFE lineempawu ezibalaseleyo ze-dielectric, amandla abalaseleyo e-dielectric kunye nokumelana ne-arc, ilahleko ye-dielectric ephantsi, kunye nokunganyangeki kwe-corona.Iphepha le-tetrafluoroethylene linokufunxwa kakuhle okungengomanzi, i-oxygen-free, i-UV kunye nokumelana nemozulu.Amandla okuqina angaphandle ahlala engatshintshanga iminyaka emithathu elandelelanayo, kukwehla kuphela ubude.Iifilimu zeTeflon kunye neengubo ziyakwazi ukungena emanzini kunye negesi ngenxa ye-porosity yazo efanelekileyo.I-PTFE inokulungela iqondo lobushushu eliphakathi kokuthabatha i-190 degrees kunye ne-250 degrees.Isenokuba shushu okanye igodole ngequbuliso, okanye itshintshe ibeshushu kwaye ibanda ngaphandle kwesiphumo.Ukongeza ekusombululeni iingxaki zokuvelisa iikhemikhali kunye nepetroleum, amaphepha e-tetrafluoroethylene nawo anokudlala indima kumayeza nakweminye imimandla.Maninzi amacandelo okutywinwa kwimarike namhlanje, kunye ne-gasket okanye iimveliso ze-gasket.Ukongeza, i-PTFE ikwasetyenziswa ngokubanzi kwizinto ezineemfuno zokutywinwa, kwaye isetyenziswa ngokuqhelekileyo njenge-Jinxining filler.Indima yephepha le-PTFE inkulu kakhulu, kuba iphepha le-PTFE linendima enkulu, iintlobo ngeentlobo zeemveliso, kwaye lidlala indima enkulu kwiinkalo ezahlukeneyo kunye neenkalo zempembelelo.I-PTFE inokubonwa kuyo yonke indawo ebomini bethu.
Okwesibini, akukhathaliseki nokuba luhlobo luni na lwekhemikhali, nokuba idleka kangakanani na, i-PTFE ingasetyenziswa.Kunokuthiwa ukuba iphepha le-PTFE alikwazi ukuhlangabezana neemfuno zokuxhathisa ukubola, akukho ezinye izinto zeplastiki ezinokusetyenziswa.Ukongeza kwimichiza egqwesileyo yokumelana nemichiza, iipropathi zayo zoomatshini nazo zibalaseleyo, nto leyo eyenza ukuba ilungele ukusetyenziswa ngezihlandlo ezinoguqulo olukhulu kunye nokugoba.
Iphepha le-PTFE lisetyenziswa ngokubanzi kwiiplastiki zobunjineli ezifana nobushushu obuphezulu 260℃, ubushushu obuphantsi -196℃, ukuxhathisa umhlwa kweasidi kunye nealkali, ukuxhathisa imozulu kunye ne-non-toxicity.I-PTFE inokubonwa kwi-petroleum, ikhemikhali, unyango, i-elektroniki kunye namashishini okutya.Nokuba ipleyiti ye-PTFE inetyhefu kwaye inokumelana nokunxiba kakuhle, yinto elungileyo yokutywina.I-PTFE (i-Polytetrafluoroethylene, efinyeziweyo njenge-PTFE), ngokuqhelekileyo ibizwa ngokuba "yi-non-stick coating" okanye "izinto ezilula ukucoceka".Esi sixhobo sineempawu zokumelana ne-asidi kunye ne-alkali kunye nokuchasana nezinyibilikisi ezahlukeneyo zezinto eziphilayo, kwaye ziphantse zinganyibiliki kuzo zonke izinyibilikisi.Kwangaxeshanye, ipleyiti ye-PTFE ineempawu zokuxhathisa ubushushu obuphezulu kunye ne-coefficient ephantsi kakhulu yokukhuhlana.Ukongeza kwi-lubrication, inkqubo yokwenziwa kwe-PTFE yokugquma ipleyiti iye yaba yinto efanelekileyo yokucoca i-layer yangaphakathi yemibhobho yamanzi.
