PTFE yog dab tsi?

Cia peb pib peb txoj kev tshawb fawb ntawm Teflon vs PTFE nrog kev soj ntsuam ze dua ntawm qhov PTFE tiag tiag yog dab tsi. Txhawm rau muab nws lub npe tag nrho, polytetrafluoroethylene yog cov khoom siv hluavtaws uas muaj ob lub ntsiab lus yooj yim; carbon thiab fluorine. Nws yog muab los ntawm tetrafluoroethylene (TFE) thiab muaj qee yam khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev siv. Piv txwv li:

• Siab melting point heev: Nrog lub melting point ntawm ib ncig ntawm 327 ° C, muaj tsawg zaus uas PTFE yuav puas los ntawm tshav kub.
• Hydrophobic: Nws tiv taus dej txhais tau hais tias nws yeej tsis ntub, ua rau nws muaj txiaj ntsig hauv kev ua noj, hnav khaub ncaws thiab lwm yam.
• Chemically inert: Feem ntau ntawm cov kuab tshuaj thiab tshuaj yuav tsis ua rau PTFE puas.
• Tsawg coefficient ntawm kev sib txhuam: Cov coefficient ntawm kev sib txhuam ntawm PTFE yog ib qho qis tshaj ntawm cov khoom nyob hauv lub neej, txhais tau tias tsis muaj dab tsi yuav lo rau nws.
• Siab flexural zog: Nws muaj peev xwm khoov thiab flex, txawm tias qhov kub thiab txias, txhais tau tias nws tuaj yeem siv tau yooj yim rau ntau qhov chaw yam tsis poob nws txoj kev ncaj ncees.

Teflon yog dab tsi?

Teflon tau tshawb pom los ntawm kev sib tsoo, los ntawm tus kws tshawb fawb hu ua Dr. Roy Plunkett. Nws tau ua haujlwm rau DuPont hauv New Jersey sim tsim lub tub yees tshiab, thaum nws pom tias cov roj TFE tau ntws tawm ntawm lub raj mis uas nws siv, tab sis lub raj mis tsis hnyav. Xav paub tias yog dab tsi ua rau qhov hnyav, nws tau tshawb xyuas sab hauv lub raj mis thiab pom tias nws tau coated nrog cov khoom siv waxy, nplua thiab oddly muaj zog, uas tam sim no peb paub tias yog Teflon.

Qhov twg zoo dua hauv Teflon vs PTFE?

Yog tias koj tau saib xyuas tam sim no, koj twb paub tias peb yuav hais li cas ntawm no. Tsis muaj tus yeej, tsis muaj cov khoom zoo dua thiab tsis muaj laj thawj los sib piv ob yam khoom ntxiv. Hauv kev xaus, yog tias koj xav paub txog Teflon vs PTFE, xav tsis thoob, vim tias lawv yog, qhov tseeb, ib qho thiab tib yam, txawv tsuas yog hauv lub npe thiab tsis muaj lwm yam.
