Calcium oxide, nrog rau cov tshuaj lom neeg CaO, yog tsim los ntawm kev ua kom cov pob zeb limestone lossis cov plhaub uas muaj calcium carbonate lwj los ntawm kev ua kom sov rau saum 825 degrees Celsius hauv lub qhov cub ci lime. Cov txheej txheem no, hu ua calcination lossis lime burning, tso cov pa roj carbon dioxide tawm, tawm hauv quicklime. Quicklime tsis ruaj khov thiab tshwj tsis yog tias slaked nrog dej los ua cov kua qaub lossis lime mortar, nws yuav tshwm sim nrog CO2 hauv huab cua thaum nws txias, thaum kawg hloov pauv rov qab mus rau hauv calcium carbonate.

Daim ntawv thov ntawm calcium oxide

Calcium oxide muaj ntau yam kev siv hauv ntau qhov chaw vim nws muaj peev xwm ua tau ntau yam. Hauv kev tsim kho, calcium oxide siv tau ua cov khoom siv hauv tsev los txhim kho qhov teeb tsa sai ntawm cov cement. Hauv cov txheej txheem hlau, nws ua haujlwm ua cov dej ntws los pab yaj cov hlau. Hauv kev ua cov roj zaub, calcium oxide ua haujlwm ua tus neeg sawv cev tshem xim los txhim kho qhov zoo ntawm cov khoom siv roj. Tsis tas li ntawd, nws kuj siv tau rau kev txhim kho av kom nce av av, ua tus neeg nqa tshuaj los txhim kho kev ruaj khov thiab bioavailability ntawm cov tshuaj, thiab ua cov chiv calcium los txhawb kev loj hlob ntawm cov nroj tsuag.

Calcium oxide kuj tseem siv los ua cov khoom siv refractory kom txhim kho qhov kub thiab txias ntawm cov khoom. Ua ib qho desiccant, nws tuaj yeem nqus cov dej noo hauv huab cua thiab ua kom cov khoom qhuav. Hauv kev kho dej khib nyiab, calcium oxide yog siv los kho cov dej khib nyiab acidic thiab sludge conditioning kom huv si dej zoo. Tsis tas li ntawd, nws kuj tseem siv los ua cov tshuaj xws li calcium carbide, soda ash, thiab bleaching hmoov.

Kev ua cov txheej txheem calcium oxide

Cov txheej txheem ua cov calcium oxide feem ntau suav nrog kev calcination ntawm limestone thiab kev sib tsoo ntawm calcium oxide. Tom qab limestone raug tsoo thiab tshuaj ntsuam, nws raug xa mus rau lub qhov cub txiv qaub rau calcination. Ntawm qhov kub siab ntawm 900 txog 1200 degrees Celsius, limestone decomposes los tsim calcium oxide thiab carbon dioxide. Tom qab calcined calcium oxide txias thiab crushed, cov khoom calcium oxide ua ntej tuaj yeem tau txais. Yuav kom tau txais cov hmoov calcium oxide zoo dua, xav tau cov khoom siv ua hmoov tshaj lij. Lub tshuab ua hmoov calcium oxide 200 mesh ua lub luag haujlwm tseem ceeb hauv qhov txuas no. Cov khoom siv no tuaj yeem sib tsoo cov calcium oxide me me rau hauv 200 mesh hmoov zoo kom tau raws li ntau yam kev xav tau ntawm daim ntawv thov.

200 mesh calcium oxide hmoov ua tshuab taw qhia

Lub tshuab ua hmoov calcium oxide 200 mesh yog cov khoom siv sib tsoo hmoov calcium oxide tshaj lij uas Guilin Hongcheng Mining Equipment Manufacturing Co., Ltd. tsim. Nws tuaj yeem sib tsoo cov hmoov calcium oxide ua hmoov zoo 200 mesh, thiab tuaj yeem kho qhov loj ntawm cov khoom tso tawm los ntawm 80 mesh mus rau 400 mesh raws li qhov xav tau tiag tiag. Cov khoom siv tuaj yeem ua rau muaj peev xwm ntau dua 40% thiab txo cov nqi siv hluav taws xob ntau dua 30%. Nws muaj suab nrov tsawg, kev ua haujlwm zoo, muaj peev xwm xa khoom loj thiab kev ua haujlwm raug. Nws yog cov khoom siv sib tsoo txo ​​suab nrov tshiab zoo tagnrho rau ib puag ncig. Tib lub sijhawm, cov khoom siv tau nruab nrog cov cav thiab cov tshuab tswj hwm siab heev, uas tuaj yeem ua tiav kev tsim khoom tsis siv neeg thiab txhim kho kev ua haujlwm zoo.
