Tshuaj fluorine tshwm sim ib txwm nyob hauv lub ntiaj teb ua kiav txhab uas nws tuaj yeem pom hauv pob zeb, thee thiab av nplaum. Cov tshuaj fluoride raug tso tawm rau saum huab cua hauv cov av uas cua tshuab tuaj. Tshuaj fluorine yog qhov tseem ceeb tshaj plaws nyob hauv ntiaj teb thib 13: lub ntiaj teb ua kiav txhab: 950 ppm tau muaj nyob hauv nws.
Xav txog qhov no, tau txais cov tshuaj fluorine li cas?
Tshuaj fluorine yog tau los ntawm kev tshuaj xyuas hluav taws xob ntawm kev daws cov tshuaj potassium hydrogendifluoride hauv anhydrous hydrofluoric acid. Cov anodes yog ua los ntawm cov pa roj carbon nyuaj txij li graphite yuav tawg sai vim qhov ntxeem tau ntawm qhov me tshuaj fluorine atoms nruab nrab ntawm cov pa roj carbon txheej. Cov cathodes yog ua los ntawm cov hlau.
Ib yam nkaus, yam khoom twg muaj fluorine? Kev siv ntawm Tshuaj fluorine Cov tshuaj fluorochemicals, suav nrog ntau cov yas kub kub xws li Teflon, kuj tseem siv tau tshuaj fluorine . Cov cheeb tsam ntawm tshuaj fluorine , suav nrog sodium fluoride, tau siv tshuaj txhuam hniav thiab hauv cov dej haus los tiv thaiv kab noj hniav.
Ib sab ntawm qhov no, fluorine siv rau dab tsi?
