项目摘要

Kruger is one of the largest Canadian company in wood transformation, papermaking, biomaterials and renewable energy with more than 110 years of history, 5000 employees and 19 manufacturing sites in North America. Nowadays, the newsprint paper, a predilection product of Canadian paper market, is in a free fall and jeopardises the existence of secular papermakers. Big companies like Kruger have no other option but to innovate in order to maintain and expand their economic activity. Recently, Innofibre, a college centre for the transfer of technology from Trois-Rivières College and CRML, a university research centre in lignocellulosic materials from Quebec University at Trois-Rivières, have developed a new pathway for the phosphorylation reaction of lignocellulosic fibers. The product, called phosphorylated fibers, has outstanding properties including fire retardant, ion exchange and water absorption capacity. However, the reaction has a significant drawback. The grafted phosphate moiety generates high repulsion charge at the surface, impairing the fibers capacity to bond each other and therefore to form a strength paper sheet. The purpose of this project will be to develop a fire retardant papermaking recipe from the phosphorylated lignocellulosic fibers without significant loose of paper strength. The influence of reaction parameters like fiber furnish, phosphorylation reagent, initial concentration, temperature, time, counter-ion species on the fire retardant efficiency and paper strength will be evaluated and quantified. At the end of the project, Innofibre will provide to Kruger a scalable best available technological solution to produce a fire retardant paper grade from phosphorylated lignocellulosic fibers.

克鲁格（Kruger）是加拿大最大的加拿大公司之一，在木材转型，造纸，生物材料和可再生能源方面拥有110多年的历史，5000多名员工和北美19个制造地点。如今，Newsprint论文是加拿大纸市场的预测产品，正在自由跌倒，并危害了世俗造纸者的存在。像克鲁格这样的大公司别无选择，只能使维护和扩大其经济活动无效。最近，Innofibre是一个从Trois-Rivières学院转移技术中心和魁北克大学木质纤维素材料的大学研究中心CRML，为木质纤维素纤维的磷酸化反应开发了新的途径。该产品称为磷酸化纤维，具有出色的特性，包括阻燃剂，离子交换和吸水能力。但是，反应具有显着的缺点。移植的磷酸盐部分在表面产生高排斥力电荷，从而损害了纤维相互结合的能力，因此会形成强度纸质纸。该项目的目的是从磷酸化的木质纤维素纤维中开发出阻燃的造纸配方，而没有明显的纸张强度。反应参数（例如纤维提供，磷酸化试剂，初始浓度，温度，时间，反离子物种）对阻燃效率和纸张强度的影响将得到评估和量化。在项目结束时，Innofibre将为Kruger提供可扩展的最佳技术解决方案，以从磷酸化的木质纤维素纤维中产生阻燃纸级。
