介绍了对漂白浆挂面箱纸板的认识和用废纸纤维研制生产的工艺技术措施,包括生产工艺流程、原料配比、生产工艺技术条件和废纸制浆工艺中采取的关键技术措施。例如改善废纸纤维原料分类;使用精密缝筛、热分散等提高分离非纤维组分,特别是蜡、胶黏物的效率;使用精密分级筛,分离长短纤维用于纸板的底层和芯层,提高产品的性价比。最后介绍了研制生产的产品达到的主要技术性能指标。
The paper introduces the cognition of bleached slough - top box cardboard and the technical measures of development and production with waste paper fiber, including the production process, the ratio of raw materials, the technical conditions of production process and the key technical measures taken in the pulping process of waste paper. Such as improving the classification of waste paper fiber raw materials; the use of precision slit screen, heat dispersion to improve the separation efficiency of non-fiber components, especially wax, stickies; the use of precision grading sieve, the separation of the length of the fiber for the bottom and core of the cardboard, Improve product cost. Finally, the main technical performance index reached by the developed products is introduced.
