摘要
为应对造纸行业增长放缓、竞争加剧及环保压力,现代大型化学浆厂正在从传统的造纸用浆生产,扩展到更高价值纤维素产品,而当前高价值纤维素产品大部分依赖国外进口,急需国产化,使得产业向更高价值纤维素产品扩展的必要性尤为突出。本文系统综述了实现这一转型的四大关键路径:开发高纯度溶解浆作为纺织与化工原料,拓展其能源、医疗等新兴应用;发展保持纤维结构的特种纤维素材料(如绒毛浆、过滤材料),以替代石化产品;开发具备优异性能的微米/纳米纤维素;以及利用制浆副产物生产生物基材料。还进一步分析了溶解浆、特种纤维素材料等核心产品的生产技术、应用现状与转型价值,并对未来通过绿色技术与产品创新驱动产业升级的前景进行了展望。
In response to the slowdown in growth,intensified competition,and environmental pressure in the papermaking industry,modern large-scale chemical pulp mills are expanding from traditional pulp production for papermaking to higher-value cellulose products.Currently,most high-value cellulose products rely on imports from abroad and there is an urgent need for domestic production,making the necessity of the industry’s expansion towards higher-value cellulose products particularly prominent.This article systematically reviewed the four key paths to achieving this transformation:Develop high-purity dissolving pulp as raw materials for textiles and chemicals,and expand its emerging applications in energy,medical care,and other fields;Develop specialty cellulose that maintain fiber structure(such as fluff pulp and filter materials)to replace petrochemical products;Develop micro/nano cellulose with excellent performance;Utilize the by-products from pulping to produce bio-based materials.The production technology and application status of these key products such as dissolving pulp and special cellulose-based materials were analyzed.The significance of transformation was pointed out,and the future industrial upgrading achieved through green technology adoption and product innovation was described.
