Dè th' annBarium Hydroxide agus Barium Hydroxide Octahydrateair a chleachdadh airson?
Gu tionnsgalach,barium hydroxideair a chleachdadh mar ro-ruithear gu todhar barium eile. Tha am monohydrate air a chleachdadh gus sulfate a dhì-hydradachadh agus a thoirt air falbh bho dhiofar thoraidhean. Mar obair-lann, tha Barium hydroxide air a chleachdadh ann an ceimigeachd anailis airson a bhith a’ toirt a-steach searbhagan lag, gu sònraichte searbhagan organach.Barium hydroxide octahydrateair a chleachdadh gu mòr ann an saothrachadh salainn barium agus todhar organach barium; mar chur-ris ann an gnìomhachas a' pheatrail; Ann an saothrachadh alkali, glainne; ann am vulcanization rubair sintéise, ann an luchd-bacadh corrach, puinnseanan; leigheas sgèile boiler; Bidh luchd-glanaidh goileadair, ann an gnìomhachas an t-siùcair, a’ càradh olaichean bheathaichean is glasraich, a’ bogachadh uisge, a’ dèanamh glainneachan, a’ peantadh a’ mhullaich; Reagent airson CO2 gas; Air a chleachdadh airson tasgaidhean geir agus leaghadh silicate.
