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
