新闻纸添加人造硅酸盐填料试验

Experimental Study of Adding Manmade Silicate Filler in Newsprint Pulp

制备人造硅酸盐填料(PSS),考查了其物理性质,分别填加PSS、滑石粉进行了对比实验,结果表明,填加PSS的性能明显优于加滑石粉和未填加时的效果。

The precipitated silicate and silica（PPS） as a manmade silicate filler have been prepared, and its physical property have been examined. The percentage of elements as Na, Si, A1 have been determined. And the comparative experiments have been completed about adding PSS or talcum powder into the news print respectively. The result shows that properties of paper are better than adding talcum powder.
