中国化学机械法制浆的生产现状、存在问题及发展趋势

Production Status and Development Trend of Chemi-Mechanical Pulping in China

化学机械法制浆具有原料适应性广、纸浆得率高、流程紧凑、设备投资省等优点,在中国得到了迅速发展。本文回顾了改革开放以来,中国化学机械法制浆生产的发展历程。在总结经验的基础上,指出了生产中存在的问题,对相关问题进行了分析并提出解决的技术建议,为相关装备制造和化学机械法制浆企业生产提供参考。随着国家废纸限制进口政策的实施,造纸工业纤维原料缺口增大,非木纤维原料高得率制浆技术将迎来一个新的发展机遇。

It is well known that chemi-mechanical pulping of wood materials is superior to chemical pulping in many aspects,such as better adaptability for raw materials,higher pulp yield,lower capital investment and more compact production lines. This paper reviews the development of chemi-mechanical pulping in China since adopting the Reform and Opening-up policy in 1978. Based on the summary of production experience,the existing problems in the production of chemi-mechanical pulping are pointed out,and the relevant problems are analyzed and the technical suggestions are given in this paper,which can provide references for the equipment manufacturers and the pulping enterprises. With the implementation of the policy of the restriction on importing waste paper from abroard,there is a big gap in the supply of fiber raw materials for Chinese paper industry,the high-yield pulping technology of non-wood fiber raw materials will be on the threshold of a new era.
