Qhov sib txawv tseem ceeb ntawm cov txiv qaub thiab cov txiv qaub dej yog qhov tsim cov txiv qaub slaked yog los ntawm kev ntxiv dej rau calcium oxide whereas cov kua txiv qaub yog los ntawm nplawm calcium hydroxide hauv dej ntshiab.
Ob qho tib si slaked txiv qaub thiab txiv qaub dej muaj calcium hydroxide ua cov tshuaj aqueous. Txawm li cas los xij, ob txoj kev daws teeb meem no sib txawv ntawm ib leeg feem ntau raws li lawv cov txheej txheem kev npaj thiab cov khoom siv raw uas peb siv hauv lawv cov khoom. Lub npe ntawm txiv qaub dej yog "kua txiv qaub" vim yog xim ntawm cov tshuaj.
Slaked txiv qaub yog dab tsi?
Slaked txiv qaub yog hydrated calcium hydroxide. Peb tuaj yeem tsim cov tshuaj no los ntawm kev ntxiv dej rau calcium oxide. Lub npe ntawm calcium oxide yog "quicklime". Peb tuaj yeem tau txais kev ceev ceev los ntawm cua sov limestone ntawm qhov kub ntawm lossis siab dua 900 centigrade. Qhov sib ntxiv ntawm cov dej rau cov calcium oxide no yog cov tshuaj tiv thaiv txaus ntshai vim tias nws yog exothermic heev.
Daim duab 01: Kev Npaj Slaked Lime
Slaked txiv qaub muaj nyob rau hauv cov hmoov los yog granules. Cov khoom kawg ntawm cov tshuaj tiv thaiv los ntawm qhov peb tsim cov tshuaj no tshwm sim raws li qhuav, hmoov zoo li hmoov nplej uas muaj lub teeb (feem ntau yog dawb) xim. Cov tshuaj no yog ib qho tseem ceeb ua tus neeg sawv cev nruab nrab rau cov dej khib nyiab hauv kev lag luam thiab rau kev ntxuav cov pa taws thiab. Tsis tas li ntawd, qhov sib xyaw no tuaj yeem sib xyaw nrog cov pa roj carbon dioxide hauv huab cua los tsim cov limestone los ntawm kev tso dej.
Dab tsi yog Lime Water?
txiv qaub dej yog cov kua qaub ntawm calcium hydroxide. Peb yuav tsum tsis txhob muab lo lus no piv nrog cov txiv hmab txiv ntoo "txiv qaub" vim hais tias nws tsis cuam tshuam nrog cov txiv qaub dej uas peb tham ntawm no. Pure txiv qaub dej tsis muaj xim. Nws muaj ib tug me ntsis earthy tsw nrog ib tug iab alkaline saj. Peb tuaj yeem tsim cov tshuaj no los ntawm kev nplawm calcium hydroxide nrog dej ntshiab thiab tom qab ntawd peb yuav tsum lim tawm cov calcium hydroxide ntau dhau uas tseem tsis tau yaj. Yog li ntawd, peb tuaj yeem tau txais cov tshuaj saturated calcium hydroxide. Lub npe ntawm cov tshuaj no yog "mis nyuj ntawm txiv qaub". Lub cev pH ntawm cov tshuaj no yog 12.4. qhov no txhais tau tias nws muaj lub hauv paus. Muaj ntau cov txiaj ntsig kev noj qab haus huv tseem ceeb ntawm cov tshuaj no;
- Nws tuaj yeem txhawb nqa peb cov dej haus
- Pab hauv plab
- Kuj, nws tuaj yeem txo txoj kev mob qog noj ntshav
- Txhim kho daim tawv nqaij zoo
- Nws txhawb kev poob phaus
Qhov txawv ntawm Slaked txiv qaub thiab txiv qaub dej yog dab tsi?
Slaked txiv qaub yog hydrated calcium hydroxide whereas txiv qaub dej yog ib tug saturated kua ntawm calcium hydroxide. Tsis tas li ntawd, slaked txiv qaub muaj calcium hydroxide nyob rau hauv nws cov unsaturated daim ntawv thaum txiv qaub dej muaj calcium hydroxide nyob rau hauv nws saturated daim ntawv nyob rau hauv cov tshuaj xwm ntawm txhua qhov kev daws teeb meem. Ib yam li ntawd, peb tsim slaked txiv qaub los ntawm calcium oxide whereas peb tsim cov txiv qaub dej los ntawm calcium hydroxide. Hauv qab no inforgraphic nthuav qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm slaked txiv qaub thiab txiv qaub dej hauv daim ntawv tabular.
Summary – Slaked Lime vs Txiv qaub Dej
Ob lub txiv qaub thiab txiv qaub dej muaj calcium hydroxide. Qhov sib txawv tseem ceeb ntawm slaked txiv qaub thiab txiv qaub dej yog tias peb tsim cov txiv qaub slaked los ntawm kev ntxiv dej rau calcium oxide whereas cov txiv qaub dej yog tsim los ntawm stirring calcium hydroxide hauv dej ntshiab.
