摘要
研究了以电石渣为原料,经浸取、碳化、过滤、洗涤、干燥制备轻质碳酸钙的工艺。用TEM、粒径分布测试对所合成的样品进行表征。重点考查了碳化反应温度、二氧化碳体积浓度、气体流速、搅拌速率等因素对反应速率及产品粒径的影响,确定了最佳的工艺条件。
The technology of preparation of light calcium carbonate by leaching,carbonization,filtrating,washing and drying precipitation using the material of carbide slag was studied,TEM and distribution measurement of particle size were employed to characterize the as-prepared samples.The effect of reaction temperature,concentration of carbon dioxide,gas velocity and stirring rate on reaction rate and particle size distribution are investigated,thus the optimal process conditions are determined.
