中文摘要:
      目的 探究不同木素含量的纸基对保鲜纸中亚氯酸钠留着率的影响规律。方法 采用化学浆和化学机械浆配抄不同木素含量的纸基, 采用涂布法制得保鲜纸, 利用 《纸浆 酸不溶木素的测定》 中的方法测定纸基中木素的含量, 用碘量法测定亚氯酸钠的留着率。结果 随着时间的延长, 纸基中亚氯酸钠的留着率均出现下降趋势, 但下降程度和速率不同。结论 纸基中木素含量与化学机械浆的比例呈正相关性, 木素会导致亚氯酸钠留着率的降低, 木素含量与亚氯酸钠留着率的降低程度呈正相关。
英文摘要:
      This study aimed to investigate the influence of different lignin content on the residual rate of sodium chlorite in preservative paper. Different portions of chemical pulp and chemi-mechanical pulp was used to make papers with different lignin contents. Coating method was applied to fresh-keeping papers. Method for acid insoluble lignin determination in pulp was used to detect lignin contents on the surface of these papers. By the way of iodimetry, the content of sodium chlorite in the papers was measured respectively. As time went by, the residual rate of sodium chlorite was decreased, but the degree and velocity were different. Our results indicated that there are positive linear relationships between the lignin content in the paper and the proportion of chemical mechanical pulp. Lignin leads to the degression of sodium chlorite in the papers. There are also positive linear relationships between the lignin content and the decrease of the sodium chlorite residual rate.
