今天南陽鈣粉廠家跟我(wo)們講講活(huo)(huo)性(xing)(xing)碳(tan)(tan)(tan)(tan)酸鈣(gai)(gai)的(de)(de)生(sheng)產工(gong)藝，讓我(wo)們可(ke)以更(geng)好的(de)(de)了(le)解我(wo)們的(de)(de)產品。活(huo)(huo)性(xing)(xing)碳(tan)(tan)(tan)(tan)酸鈣(gai)(gai)的(de)(de)生(sheng)產工(gong)藝與(yu)生(sheng)產輕質碳(tan)(tan)(tan)(tan)酸鈣(gai)(gai)大致相同，但在碳(tan)(tan)(tan)(tan)化(hua)(hua)這一(yi)(yi)工(gong)序中應嚴格操控條件，使生(sheng)成(cheng)微細的(de)(de)碳(tan)(tan)(tan)(tan)酸鈣(gai)(gai)顆粒，再(zai)用(yong)(yong)活(huo)(huo)化(hua)(hua)劑(ji)進(jin)(jin)行(xing)表(biao)面處(chu)(chu)理。行(xing)將(jiang)石(shi)灰(hui)石(shi)與(yu)煤混合，其配比約7.5左(zuo)右(you)，于900-1000℃ 溫度下在石(shi)灰(hui)窯中緞燒，二氧化(hua)(hua)碳(tan)(tan)(tan)(tan)經洗氣除(chu)塵后送碳(tan)(tan)(tan)(tan)化(hua)(hua)塔，生(sheng)石(shi)灰(hui)進(jin)(jin)消化(hua)(hua)槽，用(yong)(yong)80-90℃ 的(de)(de)熱水(shui)充分消化(hua)(hua)，制(zhi)(zhi)成(cheng)濃(nong)度約9%的(de)(de)乳液，進(jin)(jin)入(ru)碳(tan)(tan)(tan)(tan)化(hua)(hua)塔，通二氧化(hua)(hua)碳(tan)(tan)(tan)(tan)進(jin)(jin)行(xing)碳(tan)(tan)(tan)(tan)化(hua)(hua)，當碳(tan)(tan)(tan)(tan)化(hua)(hua)時懸浮液的(de)(de)PH值等(deng)于7時為反響終點，此時可(ke)引入(ru)活(huo)(huo)化(hua)(hua)劑(ji)，對生(sheng)成(cheng)的(de)(de)碳(tan)(tan)(tan)(tan)酸鈣(gai)(gai)進(jin)(jin)行(xing)表(biao)面處(chu)(chu)理。有干法表(biao)面處(chu)(chu)理和濕(shi)法表(biao)面處(chu)(chu)理， 一(yi)(yi)般(ban)選(xuan)用(yong)(yong)濕(shi)法表(biao)面處(chu)(chu)理工(gong)藝，因該法可(ke)制(zhi)(zhi)得(de)活(huo)(huo)化(hua)(hua)度高(gao)，松散功(gong)用(yong)(yong)好，透明性(xing)(xing)高(gao)的(de)(de)活(huo)(huo)性(xing)(xing)碳(tan)(tan)(tan)(tan)酸鈣(gai)(gai)。目前增(zeng)加活(huo)(huo)化(hua)(hua)劑(ji)一(yi)(yi)般(ban)有酞酸酯(zhi)偶聯劑(ji)、硬脂酸、木質素等(deng)，用(yong)(yong)量(liang)約1%-5%。完(wan)成(cheng)了(le)前面的(de)(de)化(hua)(hua)學處(chu)(chu)理后，對料液脫水(shui)分別、單調制(zhi)(zhi)得(de)白度高(gao)的(de)(de)制(zhi)(zhi)品。
