摘　　要：介绍了大型高速纸机表面施胶添加蛋白净化剂以解决膜转移施胶机计量棒糊棒的应用情况。实践表明:当蛋白净化剂对绝干淀粉的比例为10%时,施胶计量棒糊棒问题得到明显改善,换棒周期由0.5天延长至12天,且看不到施胶辊漏涂的情况。蛋白净化剂所用载体的产地和纯度对纸张表面强度有一定的影响,确定了蛋白净化剂载体的最优产地和最佳纯度。添加蛋白净化剂后,除了能有效解决计量棒糊棒问题,吨纸施胶成本还降低了7元,且与胶料相关的施胶机断纸和纸病明显减少。This paper introduces the application of protein purifying agent to the surface sizing of large high-speed paper machine to solve the problem of measuring rod pollution.The practice shows that when the ratio of protein purifying agent to absolute dry starch is 10%,the problem of sizing measuring rod pollution is obviously improved,the rod replace period is prolonged from 0.5 day to 12 days,and the missed coating of sizing roller can not be seen.The origin and purity of the carrier used for protein purifying agent have a certain influence on the surface strength of paper,and the optimal origin and purity of the carrier are ascertained.After adding the protein purifying agent,the cost of sizing was reduced by 7 yuan,and the paper breaks and defects related to sizing glue were reduced obviously.
