装饰原纸增湿強及再制浆工艺的研究

论文编号:QH009  论文字数:12982,页数:33

摘 要：近几年，由于中国经济的快速增长为造纸工业的发展提供了新的机遇与发展空间，我国纸业取得了长足的进步，纸张在各行各业应用范围不断扩大。但是与国外同行相比，我国大多造纸企业相对而言较为落后，经济效益不佳，传统产品的市场竞争十分激烈，而适用于新领域中的特殊纸种，往往给企业带来可观的效益，因此许多造纸企业在生产文化用纸、包装用纸等常规大需求量的品种的同时，开始注重生产高附加值的工业用纸、特种用纸等纸种，装饰原纸作为其中的代表正逐渐受到造纸企业的青睐。湿强度对于要用来印刷的装饰原纸来说，是一个重要的特性指标。湿強剂属于功能性添加剂，大多数是抗水解的合成树脂，在纸成形前加入到纸浆中，不仅可以提高湿强度，也可以给高速纸机的操作创造有利条件。
 本论文主要介绍了现在应用最广泛的湿強剂—聚酰胺聚胺环氧氯丙烷树脂（PAE树脂）的加入量对纸张湿强度的影响以及加过湿強剂的装饰原纸加入不同化学药品再制浆的研究。

The research for Increasing Wet Strength and Re-pulping Technology of Decorative base paper

 Abstract: In recent years, due to Chinese rapid economic growth for the paper industry for the development of new opportunities and development space, Chinese paper industry has made considerable progress in all walks of life in paper applications continue to grow. But compared with foreign counterparts, Chinese paper-making enterprises, most relatively backward and poor economic efficiency, the traditional market is extremely competitive, and apply to new areas of special types of paper, often to the business will generate substantial benefits So many paper-making enterprises in the production of cultural paper, packaging paper, and other big demand for conventional varieties at the same time, began to pay attention to the production of high value-added of industrial paper, special paper, and other kinds of paper, decorative base paper as one of the representatives are Gradually by paper-making enterprises of all ages. Wet strength to be used for the decorative printing paper, it is an important indicator of the properties. Wet Strength Agent additives are functional, most of whom are anti-hydrolysis of synthetic resin, before forming the paper into pulp, not only can improve the wet strength, high-speed paper machine can also create favorable conditions for the operation.
 This paper introduced the now the most widely used wet-strength agent - polyamide polyamine epichlorohydrin resin (PAE resin) addition on the strength of wet paper and wet strength agent added over the decorative paper with different chemicals Study re-pulping.
 Keywords: Decorative base paper; wet strength agent; Polyamine epichlorohydrin polyamide resin
