高档卷烟纸专用沉淀碳酸钙(PCC)往往存在平均粒径大小与沉降体积大小之间的矛盾,生产过程沉降体积控制技术关键在于:调节粒度分布到几乎没有小于1μm的微细PCC和大于10μm的普通PCC,石灰活性200~300mL·g-1,消化水温50~80℃,浆液浓度12%~16%,碳化反应起始温度25~30℃,碳化最高温度45~55℃,稳定地进行窑气净化和24h熟浆陈化,并根据具体情况进行工艺参数调节。
High-grade cigarette paper for precipitated calcium carbonate (PCC) often exist between the size of the average particle size and sedimentation volume of the contradiction between the production process sedimentation volume control technology lies in: adjusting the particle size distribution to almost no less than 1μm fine PCC and more than 10μm ordinary PCC with lime activity of 200-300 mL · g -1, digestion water temperature of 50-80 ℃, slurry concentration of 12-16%, initial carbonation reaction temperature of 25-30 ° C. and maximum carbonization temperature of 45-55 ° C., and stable kiln gas Purification and 24h cooked pulp aging, and according to the specific circumstances of the process parameters.
