Calcium carbide slag yog cov khib nyiab uas feem ntau yog ua los ntawm calcium hydroxide tom qab hydrolysis ntawm calcium carbide kom tau txais acetylene roj. Kev npaj cov khoom siv tshuaj los ntawm carbide slag yog rau lub hom phiaj ntawm kev siv cov peev txheej rov ua dua tshiab, thiab kev txhim kho cov txheej txheem ntsuab thiab kev txo cov nqi thev naus laus zis yuav yog qhov tseem ceeb ntawm kev tshawb fawb yav tom ntej. HCMilling (Guilin Hongcheng) yog lub chaw tsim khoom ntawmcalcium hydroxidekev ua luam dejthiabcalciumlub tshuab sib tsoo carbonatecov khoom siv. Cov hauv qab no yuav qhia koj txog cov txheej txheem ntawm kev npaj nano calcium carbonate los ntawm carbide slag.

Nano-calcium carbonate siv dav hauv roj hmab, yas, ntawv ua, kua mem thiab lwm yam teb, nrog rau kev lag luam muaj peev xwm loj heev. Hauv kev lag luam, txoj kev carbonization feem ntau yog siv los tsim nano-calcium carbonate, thiab CaO tau los ntawm calcining limestone, uas yog zom thiab ncua Ca (OH) 2 Crush, ntxiv cov khoom siv tswj cov qauv siv lead ua, dhau CO2 carbonization, dehydration, thiab kev kho qhov chaw kom tau nano-calcium carbonate. Thaum lub sijhawm no, cov pa roj pov tseg (CO2), dej pov tseg (dej dawb) thiab cov khib nyiab yuav raug tsim, uas thaum kawg yuav ua rau cov khoom zoo txo ​​qis thiab txo lossis ua tiav peb qhov pov tseg: xoom emission thiab kev txhim kho qhov zoo ntawm nano-calcium carbonate yog cov teeb meem tseem ceeb, thiab carbide slag yog ua raws li lub tswv yim tiv thaiv ib puag ncig ntawm kev kho cov khib nyiab nrog cov khib nyiab.

Tam sim no, kev npaj cov nano-calcium carbonate los ntawm calcium carbide slag feem ntau suav nrog peb txoj kev: calcination slaking, hydrochloric acid leaching thiab ammonium chloride leaching. Li Rui et al. siv txoj kev txheej txheem ntawm calcination thiab pressure slaking los ua kom calcium carbide slag react nrog CO2 flue gas hauv lub tshuab hluav taws xob carbonization kom tau txais cov khoom siv spherical nano calcium carbonate (60nm). Cov txheej txheem no tsis yog tsuas yog daws qhov kev ua qias tuaj ntawm CO2 pov tseg roj, tab sis kuj tau txais cov khoom muaj nqis ntxiv; Liu Fei et al. tau txais cov txheej txheem hydrochloric acid leaching, acidified calcium carbide slag nrog hydrochloric acid nrog pH = 8, thiab ua tiav metathesis reaction nrog sodium carbonate. Cov txiaj ntsig tau qhia tias acidified calcium carbide slag yuav txhawb nqa calcium carbonate whiskers. Qhov tshwm sim ntawm agglomeration thiab coarse forked ceg thaum kawg ua rau aragonitic calcium carbonate whiskers nrog kev faib tawm sib npaug thiab qhov sib piv siab (30-60). Piv nrog cov khoom siv raw uas muaj cov khoom purity siab, pom tau tias cov nano-carbonic acid uas tau npaj los ntawm calcium carbide slag Cov calcium ua tau raws li tus qauv hauv tebchaws thiab txo cov pa phem los ntawm carbide slag. Cov txheej txheem no tawm tswv yim txoj hauv kev zoo rau kev npaj cov nano-calcium carbonate.

Zhu Min thiab lwm tus siv ammonium chloride los kho cov calcium carbide slag, thiab tom qab ntawd npaj nano-calcium carbonate los ntawm carbonization. Cov txiaj ntsig tau qhia tias thaum qhov concentration ntawm ammonium chloride kua yog 8%, qhov siv ntawm calcium carbide slag yog ntau tshaj 92%. Hom nano-calcium carbonate (qhov nruab nrab ntawm cov khoom me me yog 38nm), qhov purity thiab whiteness ntawm cov khoom tau los ntawm cov txheej txheem no yog txog li 99.65% thiab 98.60% feem, uas daws qhov teeb meem ntawm qhov purity qis thiab qhov whiteness pluag los ntawm impurities rau nano-calcium carbonate, thiab yog ib qho kev daws teeb meem zoo rau kev siv hauv kev lag luam tom ntej Ib txoj kev ua haujlwm zoo tau muab.

Hauv kev xaus, ntau CO2 siv rau hauv kev npaj cov calcium carbonate slag, thiab kev siv cov calcium carbide slag muaj nqis ntau tuaj yeem ua tiav tib lub sijhawm. Txawm li cas los xij, nws yooj yim los tsim cov dej khib nyiab thaum qhov chaw raug hloov kho los ntawm cov tshuaj ntxiv. Yog tias nws tsis kho, nws yuav ua rau muaj kuab paug thib ob. Kev xav tau kev ua raws li Kev txiav txim siab ntxiv yog muab rau cov khoom lag luam ntawm cov tshuaj tiv thaiv kom paub txog kev rov ua dua ntawm carbide slag.
