介绍一种甲壳素有机改性元明粉部分替代玉米淀粉用于文化纸表面施胶的情况。采用改性元明粉部分替代玉米淀粉后,施胶液稳定性良好,黏度稍有增加;在保证成纸实际灰分与试验前一致的情况下,成纸主要物理指标与试验前相当;当改性元明粉替代比例为15%时,吨纸施胶成本节省17.1元。
A case of using chitin organic modified sodium sulfate to partially replace corn starch for the sizing of culture paper was introduced. The use of modified meta-Mingfen part of the replacement of corn starch, the sizing liquid good stability, a slight increase in viscosity; to ensure the actual paper ash into the paper before the test consistent with the case, the main physical indicators of paper and test before; When the substitution ratio of sodium sulfate is 15%, the cost of sizing papermaking is saved by 17.1 yuan.
