今天南陽鈣粉廠家跟我(wo)們講講活(huo)性(xing)碳酸鈣的生(sheng)(sheng)產(chan)(chan)工(gong)藝，讓我(wo)們可(ke)以(yi)更好的了(le)解(jie)我(wo)們的產(chan)(chan)品。活(huo)性(xing)碳酸鈣的生(sheng)(sheng)產(chan)(chan)工(gong)藝與生(sheng)(sheng)產(chan)(chan)輕質碳酸鈣大(da)致相同，但在碳化(hua)(hua)這一工(gong)序(xu)中應嚴格操控條件，使(shi)生(sheng)(sheng)成微細的碳酸鈣顆粒(li)，再用活(huo)化(hua)(hua)劑(ji)進(jin)行(xing)(xing)(xing)表(biao)(biao)面(mian)處(chu)理(li)(li)。行(xing)(xing)(xing)將(jiang)石灰石與煤混合，其(qi)配比約7.5左右，于(yu)900-1000℃ 溫度(du)(du)下在石灰窯中緞燒(shao)，二(er)氧(yang)化(hua)(hua)碳經(jing)洗氣除(chu)塵后送(song)碳化(hua)(hua)塔(ta)，生(sheng)(sheng)石灰進(jin)消(xiao)化(hua)(hua)槽，用80-90℃ 的熱水充分消(xiao)化(hua)(hua)，制(zhi)成濃度(du)(du)約9%的乳液(ye)，進(jin)入(ru)(ru)碳化(hua)(hua)塔(ta)，通二(er)氧(yang)化(hua)(hua)碳進(jin)行(xing)(xing)(xing)碳化(hua)(hua)，當碳化(hua)(hua)時(shi)(shi)懸(xuan)浮(fu)液(ye)的PH值等于(yu)7時(shi)(shi)為(wei)反響終點，此(ci)時(shi)(shi)可(ke)引入(ru)(ru)活(huo)化(hua)(hua)劑(ji)，對生(sheng)(sheng)成的碳酸鈣進(jin)行(xing)(xing)(xing)表(biao)(biao)面(mian)處(chu)理(li)(li)。有干法表(biao)(biao)面(mian)處(chu)理(li)(li)和(he)濕法表(biao)(biao)面(mian)處(chu)理(li)(li)， 一般選用濕法表(biao)(biao)面(mian)處(chu)理(li)(li)工(gong)藝，因(yin)該法可(ke)制(zhi)得活(huo)化(hua)(hua)度(du)(du)高(gao)，松散功用好，透明性(xing)高(gao)的活(huo)性(xing)碳酸鈣。目(mu)前增加(jia)活(huo)化(hua)(hua)劑(ji)一般有酞酸酯(zhi)偶聯劑(ji)、硬脂(zhi)酸、木質素等，用量(liang)約1%-5%。完成了(le)前面(mian)的化(hua)(hua)學處(chu)理(li)(li)后，對料液(ye)脫水分別、單調(diao)制(zhi)得白(bai)度(du)(du)高(gao)的制(zhi)品。
