Yini i-PTFE?

Ake siqale ukuhlola kwethu i-Teflon vs PTFE ngokuhlolisisa ukuthi iyini ngempela i-PTFE. Ukuze uyinike isihloko sayo esigcwele, i-polytetrafluoroethylene i-polymer yokwenziwa ehlanganisa izakhi ezimbili ezilula; i-carbon ne-fluorine. Isuselwa ku-tetrafluoroethylene (TFE) futhi inezici ezithile ezihlukile eziyenza ibe yinto ewusizo ezinhlobonhlobo zezinhlelo zokusebenza. Ngokwesibonelo:

• Iphuzu lokuncibilika eliphezulu kakhulu: Ngephuzu lokuncibilika elicishe libe ngu-327°C, kunezimo ezimbalwa kakhulu lapho i-PTFE izolinyazwa khona ukushisa.
• I-Hydrophobic: Ukumelana namanzi kusho ukuthi awabi manzi, okwenza abe wusizo ekuphekeni, ekubopheni amanxeba nokunye.
• Inert ngamakhemikhali: Iningi lezincibilikisi namakhemikhali ngeke kulimaze i-PTFE.
• I-coefficient ephansi yokungqubuzana: I-coefficient of friction ye-PTFE ingenye yezinto eziphansi kakhulu ezikhona, okusho ukuthi akukho okuzonamathela kukho.
• Amandla aphezulu e-flexural: Ikhono lokugoba nokugoba, ngisho nakumazinga okushisa aphansi, kusho ukuthi lingasetshenziswa kalula ezindaweni ezihlukahlukene ngaphandle kokulahlekelwa ubuqotho bayo.

Iyini iTeflon?

I-Teflon empeleni yatholwa ngengozi, ngusosayensi okuthiwa uDkt Roy Plunkett. Wayesebenzela i-DuPont eNew Jersey ezama ukwakha isiqandisi esisha, lapho ebona ukuthi igesi ye-TFE yayiphume ebhodleleni ayelisebenzisa, kodwa ibhodlela lalingenasisindo lingenalutho. Enelukuluku lokwazi ukuthi yini edala isisindo, waphenya ingaphakathi lebhodlela wathola ukuthi limbozwe nge-waxy material, eshelelayo futhi eqinile ngendlela exakile, manje esiyazi ukuthi iTeflon.

Yikuphi okungcono ku-Teflon vs PTFE?

Uma beninakile kuze kube manje, nizokwazi kakade ukuthi sizothini lapha. Akekho owinile, awukho umkhiqizo ongcono futhi asikho isizathu sokuqhathanisa lezi zinto ezimbili ngokuqhubekayo. Sengiphetha, uma uzibuza nge-Teflon vs PTFE, ungabe usazibuza, ngoba empeleni ziyinto eyodwa futhi efanayo, zihlukile ngegama kuphela futhi akukho okunye.
