摘要

使用药剂提高干强度是改善纸张物理机械性能的方法之一。在本文中，我们将讨论如何在纸浆中添加改性淀粉，以提高卫生纸的强度参数。在实验室实验中，我们测试了 8 种不同电荷水平、分子量和交联剂水平的制剂。在实验室试验中对强度参数、孔隙率和吸水性进行了评估。生产卫生纸最重要的强度参数是抗张强度，在使用 ECO 2777 产品时，达到了生产卫生纸最合适的参数。通过监测淀粉剂量的影响，发现最佳剂量为每吨绝干纸浆 3 千克，此时抗张强度提高了 18%，爆破强度提高了 41%，同时保持了所需的挺度、孔隙率和吸水率值。

MODIFIED STARCHES AS A MEAN OF INCREASING THE DRY STRENGTH OF TISSUE PAPERS

Application of agents to increase the dry strength is one of the ways of improving the physical-mechanical properties of papers. In the presented article, we are dealing with the application of modified starches to the pulp mass in order to increase the strength parameters of hygienic papers. In laboratory experiments, 8 types of agents were tested, which differed in charge level, molecular weight and cross-linker level. Strength parameters, porosity and water absorption were evaluated during the laboratory tests. The most important strength parameter in the production of tissue papers is the tensile strength, the most suitable parameters for the production of tissue papers were achieved when applying the product ECO 2777. By monitoring the influence of the dose of starch, it was found that the optimal dose is 3 kg per ton of absolutely dry pulp, when there is an increase in the tensile strength by 18%, the burst strength by 41% and while maintaining the required values of stiffness, porosity and water absorption.
