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。 In this paper, the effect of the number of recycled fibers, the primary fiber ratio and the relative humidity on the properties of secondary fiber dubbed newsprint was discussed. The results showed that the increase of fiber reusing times will reduce the performance of the paper, Increase to a certain extent improve the performance of the paper, but when the amount is greater than 20%, the improvement effect is somewhat reduced. Environmental relative humidity of 55% to 60%, the front and back of the paper surface strength are high, suitable for printing on paper.
