Thawj pawg ntau lawm cov khoom siv rau hydrofluoric acid tu hauv Suav teb tau ntse hloov mus rau hauv lub tsev loj

Hydrofluoric acid tu yog qhov txuas tseem ceeb hauv cov txheej txheem tso tawm. Nws cov nyhuv tu ncaj qha cuam tshuam qhov kawg ua tau zoo, ua tau zoo thiab muaj feem xyuam nrog cov txiaj ntsig ntawm cov khoom kawg. Hydrofluoric acid tu tsis tsuas yog tshem tawm cov txheej txheem ntawm cov txheej txheej tab sis kuj tau txo tus kab ntawv adsorption ntawm interface impurities. Cov cai kom huv huv yog nruj heev thiab theoretically tsis pub muaj cov khoom siv, hlau ions, lossis cov nplaum organic. Txuas nrog, dej vapor thiab oxide txheej xav tau atomic-theem tiaj tiaj ntawm cov txheej txheem kev ntseeg tau ntawm cov txheej txheem tom qab ua haujlwm.
