摘要
本文论述新闻纸的生产工艺从酸性造纸走向中性造纸的变迁。传统生产新闻纸的配方是:用75%的机械木浆(磨石磨木浆)和25%的化学木浆抄造而成的。随着人类对自然环境保护的重视,要求在新闻纸的生产中,掺有部分废旧报纸回收利用;飞跃的科学与技术进步,使废纸脱墨工艺日臻完善。从而,世界各国的废纸回收利用率日益攀升,现代化的造纸厂已有用全脱墨浆生产新闻纸了。纸机的抄造工艺,相应从传统的酸性造纸走向更为优越的中性造纸了。
This paper introduces vicissitudes of acid papermaking to neutral papermaking on the newsprint productional technique. Conventional formula of newsprint making is using 75% GP and 25% KP. Following human paying more attention to natural environment, recovery waste paper must be used in the newsprint furnish. Because of advanced science and technology, and the deinking technique becoming better and approaching perfection day by day, the waste paper recovery and utilization rates are increasing in the world. Now newsprint has been manufactured completely with deinked pulp in the morden paper mill, and the acid papermaking has been changed to neutral papermaking.
