Calcium carbide slag yog cov khoom pov tseg feem ntau yog tsim los ntawm calcium hydroxide tom qab hydrolysis ntawm calcium carbide kom tau txais cov roj acetylene.Kev npaj cov khoom siv tshuaj lom neeg los ntawm carbide slag yog rau lub hom phiaj ntawm cov khoom siv rov ua dua tshiab, thiab kev txhim kho cov txheej txheem ntsuab thiab txo cov nqi thev naus laus zis yuav yog lub hom phiaj ntawm kev tshawb fawb yav tom ntej.HCMilling (Guilin Hongcheng) yog cov chaw tsim khoom ntawmcalcium hydroxideslakingthiabcalciumcarbonate sib tsoo zebkhoom 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 yog dav siv hauv roj hmab, yas, papermaking, number case thiab lwm yam, nrog rau kev lag luam loj loj.Hauv kev lag luam, cov txheej txheem carbonization feem ntau yog siv los tsim cov nano-calcium carbonate, thiab CaO tau txais los ntawm calcining limestone, uas yog zom thiab tshem tawm Ca(OH) 2 Crush, ntxiv siv lead ua tus neeg saib xyuas, dhau CO2 carbonization, lub cev qhuav dej, thiab nto. Kev kho kom tau txais nano-calcium carbonate.Thaum lub sijhawm txheej txheem no, cov pa khib nyiab (CO2), cov dej khib nyiab (dej dawb) thiab cov khib nyiab pov tseg yuav raug tsim tawm, uas thaum kawg yuav ua rau txo qis hauv cov khoom lag luam thiab txo lossis paub txog peb qhov pov tseg Zero emission thiab txhim kho qhov zoo ntawm nano-calcium. carbonate yog cov teeb meem tseem ceeb, thiab carbide slag yog tag nrho raws li kev tiv thaiv ib puag ncig lub tswv yim ntawm kev kho cov khib nyiab pov tseg.

Tam sim no, kev npaj 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 cov txheej txheem ntawm calcination thiab siab slaking los ua calcium carbide slag react nrog CO2 flue gas nyob rau hauv lub pressurized carbonization reactor kom tau spherical nano calcium carbonate (60nm).Cov txheej txheem no tsis tsuas yog daws cov pa phem 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 nqa tawm metathesis cov tshuaj tiv thaiv nrog sodium carbonate.Cov txiaj ntsig tau pom tias acidified calcium carbide slag yuav txhawb calcium carbonate whiskers Qhov tshwm sim ntawm agglomeration thiab coarse forked ceg nws thiaj li ua rau aragonitic calcium carbonate whiskers nrog uniform tis thiab siab piv (30-60).Piv nrog cov khoom siv high-purity raw khoom, nws pom tau tias cov nano-carbonic acid npaj los ntawm calcium carbide slag Cov calcium ua tau raws li lub teb chaws tus qauv thiab alleviates cov pa phem los ntawm carbide slag.Cov txheej txheem no nthuav tawm txoj hauv kev zoo rau kev npaj nano-calcium carbonate.

Zhu Min thiab lwm tus siv ammonium chloride los pretreat calcium carbide slag, thiab tom qab ntawd npaj nano-calcium carbonate los ntawm carbonization.Cov txiaj ntsig tau pom tias thaum qhov concentration ntawm ammonium chloride tov yog 8%, qhov kev siv ntawm calcium carbide slag yog tshaj 92%.Hom nano-calcium carbonate (qhov nruab nrab particle loj yog 38nm), purity thiab whiteness ntawm cov khoom tau los ntawm cov txheej txheem no yog mus txog 99.65% thiab 98.60% feem, uas daws tau qhov teeb meem ntawm tsawg purity thiab tsis zoo whiteness tshwm sim los ntawm impurities rau nano- calcium carbonate, thiab yog ib qho kev daws teeb meem zoo rau cov ntawv thov kev lag luam tom ntej Ib txoj hauv kev zoo tau muab.

Hauv cov ntsiab lus, CO2 ntau ntau yog siv rau hauv kev npaj ntawm calcium carbonate slag, thiab kev siv nyiaj ntau ntxiv ntawm calcium carbide slag tuaj yeem ua tiav tib lub sijhawm.Txawm li cas los xij, nws yog ib qho yooj yim los tsim cov dej khib nyiab thaum lub npoo yog hloov los ntawm cov tshuaj additives.Yog tias tsis kho, nws yuav ua rau muaj kuab paug thib ob.Cov kev xav tau tom qab ntxiv kev txiav txim siab yog muab rau cov khoom siv los ntawm cov tshuaj tiv thaiv kom paub txog kev rov ua dua ntawm carbide slag.
