1 重质碳酸钙概述碳酸钙工业产品因其生产方式不同分为重质碳酸钙和轻质碳酸钙,其化学组分均为 CaCO_3。重质碳酸钙是非化学方法生产的碳酸钙产品,主要用机械或物理的方法将矿石直接粉碎成不同粒级的粉状物。由于沉降体积相对比沉淀碳酸钙(即轻质碳酸钙)重,所以泛称重质碳酸钙。轻质碳酸钙又称沉淀碳酸钙,它是一种用化学合成方法生产的碳酸钙产品,由石灰乳和二氧化碳直接化合经沉淀、过滤、干燥得到的粉状产品.
A heavy calcium carbonate Overview Calcium carbonate industrial products because of their different production methods are divided into heavy calcium carbonate and light calcium carbonate, the chemical components are CaCO3. Heavy calcium carbonate is a non-chemical production of calcium carbonate products, mainly by mechanical or physical methods directly crushed ore into different size fractions of powder. As the sedimentation volume is relatively heavier than precipitated calcium carbonate (ie, light calcium carbonate), so-called heavy calcium carbonate. Calcium carbonate, also known as precipitated calcium carbonate, which is a chemical synthesis of calcium carbonate products produced by the direct combination of milk and carbon dioxide precipitation, filtration, drying the resulting powder products.
