今天南陽鈣粉廠家跟(gen)我(wo)們(men)講講活(huo)性(xing)碳(tan)(tan)酸鈣(gai)的生(sheng)(sheng)產(chan)工(gong)(gong)(gong)藝，讓(rang)我(wo)們(men)可以更好(hao)的了解我(wo)們(men)的產(chan)品。活(huo)性(xing)碳(tan)(tan)酸鈣(gai)的生(sheng)(sheng)產(chan)工(gong)(gong)(gong)藝與生(sheng)(sheng)產(chan)輕質(zhi)碳(tan)(tan)酸鈣(gai)大致相同，但(dan)在碳(tan)(tan)化(hua)(hua)(hua)這一工(gong)(gong)(gong)序(xu)中應嚴格(ge)操控條件，使生(sheng)(sheng)成(cheng)微細(xi)的碳(tan)(tan)酸鈣(gai)顆粒，再用(yong)活(huo)化(hua)(hua)(hua)劑(ji)進(jin)行(xing)表面處理(li)。行(xing)將石灰石與煤混合，其配(pei)比約(yue)7.5左右，于900-1000℃ 溫度(du)(du)下在石灰窯中緞(duan)燒，二氧(yang)化(hua)(hua)(hua)碳(tan)(tan)經洗氣(qi)除塵后送碳(tan)(tan)化(hua)(hua)(hua)塔，生(sheng)(sheng)石灰進(jin)消(xiao)化(hua)(hua)(hua)槽，用(yong)80-90℃ 的熱水充分消(xiao)化(hua)(hua)(hua)，制(zhi)成(cheng)濃度(du)(du)約(yue)9%的乳液，進(jin)入碳(tan)(tan)化(hua)(hua)(hua)塔，通二氧(yang)化(hua)(hua)(hua)碳(tan)(tan)進(jin)行(xing)碳(tan)(tan)化(hua)(hua)(hua)，當碳(tan)(tan)化(hua)(hua)(hua)時懸浮液的PH值(zhi)等(deng)于7時為反響終點，此時可引(yin)入活(huo)化(hua)(hua)(hua)劑(ji)，對生(sheng)(sheng)成(cheng)的碳(tan)(tan)酸鈣(gai)進(jin)行(xing)表面處理(li)。有干法(fa)表面處理(li)和濕法(fa)表面處理(li)， 一般選用(yong)濕法(fa)表面處理(li)工(gong)(gong)(gong)藝，因該法(fa)可制(zhi)得(de)活(huo)化(hua)(hua)(hua)度(du)(du)高，松散功用(yong)好(hao)，透(tou)明性(xing)高的活(huo)性(xing)碳(tan)(tan)酸鈣(gai)。目前增加活(huo)化(hua)(hua)(hua)劑(ji)一般有酞酸酯偶聯劑(ji)、硬(ying)脂(zhi)酸、木質(zhi)素(su)等(deng)，用(yong)量約(yue)1%-5%。完成(cheng)了前面的化(hua)(hua)(hua)學處理(li)后，對料液脫水分別(bie)、單調制(zhi)得(de)白度(du)(du)高的制(zhi)品。
