Polytetrafluoroethylene feem ntau hu ua Teflon.
Nws muaj qee yam hydrophobic thiab oleophobic nyhuv, uas yog, cov nyhuv ntawm tsis lo rau dej thiab tsis lo rau roj raws li koj hais.
Rau oleophobicity, muaj ob qhov kev ntsuam xyuas dav dav, uas yog lub kaum sab xis oleophobic thiab lub kaum sab xis.
Qhov loj dua lub oleophobic lub kaum sab xis, lub thinner cov roj stain yuav yog, thiab yog hais tias nws yog ib tug poob, nws yuav tsim ib tug kheej kheej.
Qhov me me ntawm dov lub kaum sab xis, nws yooj yim dua rau cov roj tee rau yob.
Muaj cov qauv ntsuas tshwj xeeb rau kev txiav txim siab ntawm lub kaum sab xis hydrophobic thiab dov lub kaum ntse ntse.
Rapeseed roj muaj viscosity siab. Yog tias lub kaum sab xis oleophobic ntawm cov roj zaub ntawm Teflon tsis loj txaus, nws yuav kis tau ncaj nraim thiab yuav tsis sib sau; Yog tias lub kaum sab xis yob tsis txaus, nws yuav tsis yob, thiab yog tias nws raug yuam kom yob, ib txoj hlua ntawm cov hlaws me me yuav tsim tom qab.
Yog li, tsis muaj dab tsi tsis yog lo rau cov kua.
Thaum kawg, cov ntsiab lus ntawm hydrophobic thiab oleophobic, kev tu tus kheej thiab kev ntxuav yooj yim muaj ob qho tib si zoo sib xws thiab qhov sib txawv.
Kev tu tus kheej feem ntau txhais tau hais tias nws tuaj yeem raug tshem tawm ntawm nws tus kheej hauv ib puag ncig ntuj; yooj yim-rau-huv tso cai rau tu nrog ib tug me me ntawm sab nraud quab yuam.
Yog tias lub lauj kaub uas tsis yog nplaum yog ntxuav nws tus kheej, tom qab koj ua tiav, tig nws rov qab thiab lub lauj kaub yuav huv. Ib qho yooj yim los ntxuav, uas yog, koj yuav tsum yaug nws nrog dej thiab so nrog ib daim ntaub los ntxuav nws.
