Calcium hydroxide

nkowa nkenke:

lime hydrated ma ọ bụ lime hydrated Ọ bụ kristal ntụ ntụ ọcha hexagonal.Na 580 ℃, mfu mmiri na-aghọ CaO.Mgbe a na-agbakwunye calcium hydroxide na mmiri, a na-ekewa ya ụzọ abụọ, a na-akpọ ihe ngwọta dị elu nke a na-akpọ clarified lime water, na nkwusioru nke ala ka a na-akpọ mmiri ara ehi lime ma ọ bụ lime slurry.N'elu oyi akwa nke mmiri lime doro anya nwere ike ịnwale carbon dioxide, na ala oyi akwa nke mmiri ara ehi lime mmiri ozuzo bụ ihe eji ewu ụlọ.Calcium hydroxide bụ alkali siri ike, nwere bactericidal na ikike mgbochi corrosion, nwere mmetụta na-emerụ emerụ na akpụkpọ ahụ na akwa ákwà.
