碳酸钙是造纸业三大填料之一 ,重钙过去只能以湿法生产 -2μm级产品作为造纸业高档填料———表涂材料。本文是使用国产干法超细粉碎设备生产的 -2μm级产品作为造纸表涂材料的应用研究结果。
Calcium carbonate is one of the three major fillers in the papermaking industry. In the past, heavy calcium was only produced in the wet process at -2μm grade as high grade filler in the papermaking industry --- surface coating materials. This article is the application of the -2μm grade products produced by domestic dry-process ultrafine comminution equipment as the paper coating material.
