摘要
研究了两种类型重质碳酸钙超细微粉的制备及其在涂布纸中的应用。试验结果表明：使用圆盘磨两段干磨、搅拌磨湿式超细磨制取的重钙超细微粉，粒度可达－２μｍ≥９０％；用于涂布纸生产可以取代优等硫酸钡。
Preparation of two-types of GCC ultrafines and its application to coated paper making were studied. The results shows that the GCC products with over 90% -2μm in size can be obtained through two-stage dry grinding with disc mill and ultra-fine hydro-grinding with stirring mill. As a considerable white pigment, it can replace high grade barium sulfate in coated papers making.
