ZD-50B碳酸钙4 Note manufacturing The Company production of ultra-fine activated calcium carbonate, select China's quality calcite mineral raw materials and advanced additive at home and abroad, the wet ultrafine grinding, powerful dry depolymerization, multi-coated activated. Low water products, purity, and high brightness, fine particle size, narrow particle size distribution, no big grain reunion, the unique modified product activation process completely coated and easy to fully dispersed in the organic polymer system is special textile, calendering , coating, the high proportion of functional materials with reinforced toughening, the role of cost reduction. GCC ordinary mill, the escalation of light calcium products. Product Character Reasonable grain shape and size distribution, process and the activation of a unique formula, creating good dispersion, extraction of low, low moisture and resin have greater contact area and strong avidity. 技术指标说明 产品指标 单位 ZD-50A ZD-50B 白  度 % 95.0 95.0 细  度 目 7000目 4000目 -2μm粒  度 % ≥95.0 ≥80.0 （105℃）含水量 % ≤0.3 ≤0.3 325目筛余量 % ≤0.001 ≤0.001 比表面积 cm2/g ~8000 ~4000 DOP吸油量 g/100g 24±4 20±4   粒度分布参考附浙地湿法超细研磨碳酸钙产品
