The chemical composition,petrographic analysis and dispersing property of kinds of bauxitic clay are compared.

对比研究了几种铝矾土组成、相组成和分散性能。

In addition, non-coated paper in high-humidity environment of sulfide, chemical pulp and fill applicatron dottle out acid melted, making of gold and silver monlchamus nigrescent who lose their luster.

此外，否涂纸在湿度境况下，纸浆硫物以及增磕酸矾土感，也会使纸背上金、银不朱发黑而获得光华度。
