A compound alkali yog ib qho tshuaj npaj los ntawm kev sib xyaw ob lossis ntau dua alkaline tebchaw (xws li sodium hydroxide, calcium hydroxide, sodium carbonate, thiab lwm yam) hauv ib qho piv txwv. Piv nrog ib txwm alkalis, nws qhov zoo yog:
Synergistic effect: Cov khoom sib txawv alkaline sib xyaw ua ke, ua rau muaj kev hloov pauv pH ruaj khov. Piv txwv li, calcium hydroxide muaj solubility tsawg tab sis tus nqi qis; sib tov nws nrog sodium hydroxide tuaj yeem txhim kho nws cov solubility.
Multifunctionality: Nws muaj ntau yam tshuaj ua haujlwm, suav nrog kev ua haujlwm nruab nrab, nag lossis daus, thiab desulfurization.
Kev lag luam: Cov khoom siv raw tau yooj yim, thiab cov nqi tsim khoom yog 10% -30% qis dua cov alkalis ib leeg (Cov ntaub ntawv: 2022 Kev Tshawb Fawb Tshaj Tawm Txog Kev Kho Dej Kho).
