摘要
本论文对纤维回用次数、一次纤维配比和环境相对湿度对二次纤维配抄新闻纸性能的影响进行了探讨,结果发现纤维回用次数增加会降低纸张的各项性能,而一次纤维配比的增加在一定程度上改善纸张的各项性能,但是当其用量大于20%时,其改善效果有所降低。环境相对湿度为55%～60%时,纸张的正反面表面强度均较高,适合于纸张印刷。
The effects of fiber recycling times, primary fiber ratio and environment relative humility on the perform- ances of newsprint using secondary fiber as furnish were discussed in this paper. The results show that the perform- ance decreased with the increase of fiber recycling times, but with the increase of primary fiber ratio, the properties of secondary fiber newsprint were improved. As the ratio of primary fiber was more than 20%, the improvement efficiency decreased. When the relative humility of environment was 55% ~60% , the surface strength of both sides of paper was higher, which was fit for paper pressing.
