Yini i-PTFE?

Ake siqale ukuhlola kwethu kweTeflon vs PTFE ngokuhlola okusondele kakhulu kwalokho okuyi-PTFE. Ukuyinika kuyisihloko esigcwele, i-polytetrafluorooroethylene iyi-polymer yokwenziwa ehlanganisa izinto ezimbili ezilula; ikhabhoni ne-fluorine. Isuselwa kuTetrafluoroethylene (TFE) futhi inezakhiwo ezithile ezihlukile ezenza kube yinto ewusizo ezinhlobonhlobo zezicelo. Ngokwesibonelo:

• Iphuzu eliphakeme kakhulu elincibilikayo: Ngephuzu lokuncibilika elingaba ngu-327 ° C, kunezimo ezimbalwa kakhulu lapho i-PTFE izolinyazwa khona ngokushisa.
• Hydrophobic: Ukumelana namanzi kusho ukuthi akukaze kube manzi, okwenza kube lusizo ekuphekeni, ukugqoka okulimaza nokuningi.
• Ngokwezifiso zamakhemikhali: Iningi lama-solvents namakhemikhali ngeke alimaze i-PTFE.
• I-coefficient ephansi yokuxabana: I-coefficient of Ptfe ye-PTFE ingenye ephansi kakhulu kunoma yikuphi okuqinile okukhona, okusho ukuthi akukho lutho oluzonamathela kulo.
• Amandla aphezulu aguqukayo: Yikhono lokugoba nokushintshashintsha, ngisho nasemazingeni okushisa aphansi, kusho ukuthi kungasetshenziswa kalula ezindaweni ezahlukahlukene ngaphandle kokulahlekelwa ubuqotho bayo.

Yini i-teflon?

UTeflon empeleni watholwa ngengozi, usosayensi obizwa ngokuthi nguDkt Roy Plunkett. Ubesebenzela iDuPont eNew Jersey ezama ukuthuthukisa isiqandisi esisha, lapho ebona ukuthi igesi ye-TFE igele ngaphandle kwebhodlela ayelisebenzisayo, kodwa ibhodlela lalingakaze libe yilutho. Ufuna ukwazi ukuthi yikuphi okwakudala isisindo, waphenya ingaphakathi lebhodlela futhi wakuthola kuhlanganiswe ne-waxy impahla, eshelelayo futhi eqinile, esikwaziyo manje, manje esikwaziyo ukuba yi-teflon.

Yini engcono eTeflon vs PTFE?

Uma ngabe ubhekisisa kuze kube manje, uzokwazi ukuthi sizothini lapha. Akukho ophumelele, awukho umkhiqizo ongcono futhi asikho isizathu sokuqhathanisa lezi zinto ezimbili. Ekuphetheni, uma uzibuza ngeTeflon vs PTFE, ungabe usamangalela, ngoba empeleni, eqinisweni, into efanayo, ehlukile kuphela ngegama futhi akukho okunye.
