Isishwankathelo esiBanzi se-PTFE kunye noKuguquguquka kwayo kwiiNkqubo zale mihla
I-Polytetrafluoroethylene (PTFE) yipolymer eyenziweyo eye yafumana ukuthandwa kumashishini ahlukeneyo ngenxa yokuxhathisa okukhethekileyo kweekhemikhali kunye neepropati ezingabambekiyo.Esi sixhobo yiplastiki ephezulu yokusebenza enokumelana nokushisa okukhulu, okwenza kube yinto ethembekileyo yokukhetha izicelo ezahlukeneyo.Kweli nqaku, siza kujonga ngakumbi apho i-PTFE isetyenziswa khona kunye neenzuzo zayo ezininzi kumashishini ahlukeneyo.
Izicelo zoShishino
I-PTFE isetyenziswa ngokubanzi kwizicelo zemizi-mveliso ezifana nokusetyenzwa kweekhemikhali, i-oyile kunye negesi, kunye nokuveliswa kwe-semiconductor.Ukumelana neekhemikhali zayo kunye neempawu ezingabambekiyo zenza ukuba ibe yinto efanelekileyo kwiitanki ze-lining, imibhobho, kunye nezixhobo ezivezwe kwizinto ezinobungozi.I-PTFE ikwasetyenziswa kwiibheringi, itywina, kunye neegaskets ngenxa yokukwazi ukumelana nobushushu obuphezulu kunye noxinzelelo.
Izicelo zonyango
I-PTFE isetyenziswa ngokuqhelekileyo kwishishini lezonyango ngenxa ye-biocompatibility kunye ne-non-reactivity kunye nezicubu zomntu.Isetyenziselwa ukufakelwa kwezonyango, ezifana ne-cardiovascular grafts kunye ne-artificial joints, njengoko ayinayo inetyhefu kwaye ayibangeli ukuphendula komzimba.I-PTFE iphinda isetyenziswe kwii-catheters kunye nezinye izixhobo zonyango ngenxa yeempawu zayo zokungakhuni, ezinciphisa umngcipheko wamahlwili egazi kunye nosulelo.
Ishishini loMbane kunye nele-Electronics
I-PTFE sisigqubuthelo sombane esigqwesileyo, sisenza ukuba ibe yimathiriyeli edumileyo kwizinto zombane neze-elektroniki.Ngokuqhelekileyo isetyenziswe kwi-insulation yocingo kunye nentambo, iibhodi zeesekethe eziprintiweyo, kunye nezinye izixhobo zombane ezifuna umgangatho ophezulu wokugquma.Ukuxhathisa kwe-PTFE kubushushu kunye neekhemikhali kuyenza ibe lukhetho oludumileyo kwizicelo zebhetri kunye ne-capacitor.
Ukuqukumbela, i-PTFE yimathiriyeli eguquguqukayo kakhulu esetyenziswa kumashishini ahlukeneyo ngenxa yokumelana neekhemikhali ezikhethekileyo, iipropathi ezinganamatheli, kunye nokukwazi ukumelana nobushushu obugqithisileyo.Ukususela kwizicelo zoshishino ukuya kwishishini lokutya kunye nesiselo, izicelo zonyango, i-aerospace kunye nemizi-mveliso yeemoto, kunye neshishini lombane kunye ne-electronics, i-PTFE ibe yinto ebalulekileyo kwizicelo ezahlukeneyo.Ngeempawu zayo ezizodwa kunye nokuguquguquka, i-PTFE iya kuqhubeka nokudlala indima ebalulekileyo kwizicelo zanamhlanje.
I-Aerospace kunye ne-Automotive Industry
Iipropati ezizodwa ze-PTFE ziyenza ibe lukhetho oludumileyo kwi-aerospace kunye noshishino lweemoto.I-coefficient yayo ephantsi ye-friction yenza ukuba ilungele ukusetyenziswa kwiibheringi, iigiya, kunye nezinye iindawo ezihambayo ezifuna ukusebenza okuphezulu kunye nokunxiba okuphantsi.I-PTFE ikwasetyenziswa njengesixhobo sokugquma iinqwelomoya kunye namalungu emoto ukuwakhusela ekugugeni nasekudlekeni.
Ishishini lokutya neziselo
Kwishishini lokutya nesiselo, i-PTFE isetyenziselwa ukwenza oomatshini bomgangatho wokutya kunye nezixhobo ezinje ngamabhanti okuhambisa, imibhobho, kunye netywina.Ngenxa yeempawu zayo ezingezizo, i-PTFE ikhusela amaqhekeza okutya ukuba abambelele kwisixhobo, okwenza kube lula ukucoca nokugcina imigangatho yococeko ephezulu.I-PTFE ikwasetyenziswa kwizinto zotyalo lokupheka njengendawo yokungakhuni.
