Tshauv calcium hmoov thiab calcium hydroxide, uas yog, slaked txiv qaub, yog ob qho tib si txiv qaub refined hmoov khoom. Lawv puas yog tib yam? Qhov tseeb, hauv kev nkag siab dav, ob qho tib si, lub ntsiab lus tseem ceeb yog calcium hydroxide, tab sis muaj qhov sib txawv ntawm kev siv tshuab, cov khoom tiav, kev siv, nqi, thiab lwm yam. Cia kuv qhia koj seb qhov sib txawv ntawm ob yog dab tsi. .
1. Kev lag luam siv
Qhov no yog qhov sib txawv loj. Cov hmoov tshauv calcium feem ntau yog siv rau hauv kev tsim kho, txheej txheej, thiab lwm yam, xws li cib, pleev xim rau phab ntsa, mortar, putty hmoov, dej-raws li txheej, thiab lwm yam.; thaum calcium hydroxide siv ntau dua hauv kev lag luam thiab kev tiv thaiv ib puag ncig, xws li tawv, metallurgy, papermaking. Kev kho dej phwj tuaj, flue gas desulfurization, thiab zaub mov, tshuaj thiab lwm yam lag luam.
2. Kev siv tshuab
Affected by the use, the two are also different in production. Ash-calcium powder is obtained by fully digesting lime (block ash) with water and "aging", and then selecting powder through mechanical equipment (usually an ash-calcium machine). Calcium hydroxide is obtained by digesting lime (block ash) with water and screening it by powder selection equipment, which can be produced while digesting. Of course, food and pharmaceutical grade calcium hydroxide is another matter.
3. Cov khoom ntsuas
Cov hmoov tshauv calcium hmoov thiab calcium hydroxide uas ua los ntawm cov txheej txheem sib txawv ib txwm muaj cov kev qhia sib txawv. Cov calcium thiab magnesium cov ntsiab lus ntawm cov hmoov tshauv calcium hmoov yuav tsum muaj ntau dua lossis sib npaug li 90 feem pua, cov dej noo ntau dua lossis sib npaug li 2 feem pua, qhov dawb yog tsawg kawg yog 90 lossis ntau dua, thiab qhov fineness ntau dua 325 mesh, feem ntau ntawm 325 thiab 600 mesh; Thaum cov ntsiab lus calcium hydroxide xav tau ntau dua lossis sib npaug li 90 feem pua, cov dej noo tsawg dua lossis sib npaug li 1 feem pua, qhov yuav tsum tau whiteness tsis siab npaum li cov hmoov tshauv calcium hmoov, thiab qhov fineness feem ntau ntawm 200 thiab 325 mesh.
4. Nqe tso cai
Ash calcium hmoov feem ntau muab faib ua cov hmoov tshauv calcium hmoov thiab cov hmoov tshauv ntshiab calcium raws li kev siv. Tus nqi ntawm cov hmoov tshauv calcium hmoov yog txiav txim raws li hnyav npaum li cas calcium hmoov ntxiv rau hauv cov hmoov tshauv calcium hmoov; thaum calcium hydroxide feem ntau tsis tuaj yeem ntxiv nrog cov hmoov calcium hnyav, uas txiav txim siab nws tus nqi. Nws yog qhov tseem ceeb ntawm cov ntsiab lus calcium zoo hauv cov khoom, uas feem ntau muab faib ua 80 feem pua -85 feem pua, 86 feem pua -90 feem pua, 91 feem pua -95 feem pua, thiab cov nqi ntawm txhua qib feem ntau yog hais txog. 60-100 yuan ib tuj.
Cov saum toj no yog qhov sib txawv ntawm cov hmoov tshauv calcium hmoov thiab calcium hydroxide. Ordinary calcium hydroxide tsis tuaj yeem siv los hloov cov hmoov tshauv calcium hmoov hauv cov txheej txheem vaj tsev, tab sis cov hmoov tshauv calcium uas ua tau raws li tus qauv tuaj yeem siv hauv kev lag luam es tsis txhob siv calcium hydroxide.
