Slaked txiv qaub, tshuaj hu ua calcium hydroxide, yog ib qho inorganic compound nrog cov tshuaj formula Ca(OH)₂.
Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm calcium oxide (quicklime, CaO) nrog dej; cov txheej txheem tshuaj tiv thaiv no tseem hu ua slaking lossis digestion ntawm txiv qaub. Slaked txiv qaub yog dawb, hmoov khoom nyob rau hauv chav tsev kub thiab yog me ntsis soluble hauv dej; Nws cov tshuaj aqueous hu ua limewater thiab yog alkaline.
Los ntawm kev xav txog kev sib xyaw, lub ntsiab lus tseem ceeb ntawm slaked txiv qaub yog calcium hydroxide, muaj zog alkali nrog cov khoom corrosive. Hauv kev tsim khoom lag luam, purity ntawm slaked txiv qaub txawv nyob ntawm cov txheej txheem tsim khoom thiab nws cov kev npaj siv, tab sis feem ntau, siab - cov txiv qaub zoo muaj cov ntsiab lus calcium hydroxide. Dhau li ntawm calcium hydroxide, slaked txiv qaub kuj tseem muaj me me ntawm calcium oxide, dej, thiab muaj peev xwm impurities xws li silica, alumina, thiab hlau oxide. Cov ntsiab lus ntawm cov impurities no feem ntau yog tsawg thiab sib txawv nyob ntawm cov khoom siv raw thiab cov txheej txheem ntau lawm.
Slaked txiv qaub muaj kev siv dav hauv ntau lub teb. Hauv kev tsim kho kev lag luam, slaked txiv qaub yog cov khoom siv tseem ceeb rau kev npaj cov khoom siv hauv tsev xws li txiv qaub mortar, txiv qaub slurry, thiab txiv qaub- av. Hauv thaj chaw tiv thaiv ib puag ncig, vim nws cov khoom alkaline, slaked txiv qaub tau siv dav hauv kev kho dej khib nyiab thiab cov pa roj desulfurization tej yaam num kom neutralize acidic khib nyiab los yog pa gases thiab txo ib puag ncig muaj kuab paug. Tsis tas li ntawd, slaked txiv qaub yog siv nyob rau hauv kev ua liaj ua teb raws li cov av txias rau neutralize av acidity thiab txhim kho av fertility. Hauv kev lag luam chemical, slaked txiv qaub kuj yog ib qho tseem ceeb raw khoom rau kev npaj lwm cov calcium sib txuas, xws li calcium carbonate thiab calcium chloride.
Thaum siv slaked txiv qaub, nws yog ib qho tseem ceeb kom paub txog nws qhov muaj zog alkalinity thiab corrosiveness, thiab kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag kom tsis txhob raug mob. Slaked txiv qaub yuav tsum tau qhuav kom qhuav thaum lub sij hawm cia thiab thauj mus los los tiv thaiv nws los ntawm absorbing noo noo, clumping, los yog deteriorating. Hauv kev tsim khoom lag luam, nws yog qhov tsim nyog los xaiv cov khoom lag luam slaked txiv qaub uas tsim nyog purity thiab zoo raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau los xyuas kom meej nws cov txiaj ntsig thiab kev nyab xeeb.
