Dab tsi yogBarium hydroxide thiab barium hydroxide Octahydratesiv rau?
Kev lag luam muaj kev lag luam,barium hydroxideyog siv raws li cov txheej txheem ua ntej mus rau lwm lub Barium sib txuas. Monohydrate yog siv los ua kom lub cev qhuav dej thiab tshem cov sulfate los ntawm ntau yam khoom. Raws li kev kuaj siv hydrof, Barium Hydroxide siv tau hauv kev tshawb nrhiav anchister rau lub kaum lub zog, tshwj xeeb yog cov organic acids.Barium hydroxide Octahydrateyog qhov dav nyob rau hauv kev tsim cov khoom tsim ntawm cov ntsev ntawm cov ntsev thiab barium organic sib txuas; raws li kev ntxiv nyob rau hauv kev lag luam roj av; Hauv kev tsim cov alkali, iav; hauv cov roj hmab roj hmab vulcanization, hauv kev xeb txwv tsis pub tshuaj tua kab; Boiler Shoud tshuaj; Cov tshuaj yej boiler, hauv kev lag luam qab zib, kho tsiaj thiab roj zaub, dej muag muag, pleev xim rau lub qab nthab; Reagent rau co2 roj; Siv rau cov roj tso nyiaj thiab cov silishing smelting.
