| 中文摘要: |
| 应用淀粉复配硅酸钠水溶液作为表面施胶剂提高瓦楞原纸的环压强度和耐破度。讨论了淀粉-硅酸钠复配体系的黏度及其对瓦楞原纸主要强度指标的影响，并通过Cobb值和接触角表征了施胶后纸张的防水性能。与传统表面施胶剂相比，淀粉-硅酸钠复配体系克服了普通表面施胶剂施胶量低、胶层挺硬性不高的缺陷，使瓦楞原纸的环压强度增幅最高可达80%，耐破度增幅最高可达51%。 |
| Abstract: |
| In this paper, a starch-sodium silicate compound system was employed as a surface sizing agent to improve the strength of corrugating medium. The viscosity of the compound system and the impact of the system on ring-crush strength and bursting strength of corrugating medium were studied, and Cobb value was used to characterize the waterproof performance of the surface sized paper. Compared with conventional surface sizing agents, a higher sizing load could be realized by using the compound system and therefore a much higher stiffness of paper could be achieved. The ring-crush and bursting strength of corrugating medium were increased by up to 80% and 51% respectively. |
