二次纤维配抄新闻纸印刷适性的研究

Study on the Printability of Newspaper Using Secondary Fiber as Furnish

本文主要研究了二次纤维抄造新闻纸的印刷适性,研究发现,完全由二次纤维或由二次纤维配比其它化学机械木浆进行配抄,而不加入任何助剂,所抄造出来的纸张的平滑度和表面强度等性能是不符合印刷要求的,当加入2%的滑石粉和3%的阳离子淀粉,所抄造的纸张的印刷适性会有明显的改善,并且浆料的最佳配比是90%的废纸浆加10%的化机浆。

The printability of newspaper using secondary fiber as furnish was mainly studied in this paper. The results showed： the newspaper completely made by secondary fiber or by secondary fiber in proportion with other chemical wood pulp, and without any additive, did not satisfy to the requirement of newspaper printing, such as smoothness, surface strength and so on. But the addition of some additive and filler can improve the printability of the newspaper obviously, such as 2% talc powder and 3% cationic starch, the optimal ratio of the furnish is 90% of secondary stock and 10% of chemi - mechanical pulp.
