Domtar Inc. is one of the largest producers of uncoated free sheet in the world and one of the main paper grade pulp producers in North America. Domtar has developed and patented a specific pulp with a high hydrodynamic specific surface area, with minimal loss in fiber length and lower fines production. The Surface Enhanced Pulp Fiber (SEPF) was previously studied in Innofibre and demonstrated the pulp potential as paper reinforcement when added in other paper grade. The pulp dewatering capacity limits its production and commercialization. After dewatering and re-pulping, the pulp properties are affected, and the potential use of pulp significantly decreased. This project will able to understand the dewatering effect on the pulp at laboratory scale dewatering involving mechanical water removing and dehydration by heat transfer. Optimization of pilot scale dewatering technologies using experimental designs will then give needed information to Domtar to implant the most beneficial dewatering system adapted to SEPF. Therefore, Domtar will be able to further develop the SEPF use and commercialization and to remain a pulp manufacturer leader in Canada, North America and in the world.

Domtar Inc. 是全球最大的无涂层自由纸生产商之一，也是北美主要的纸级纸浆生产商之一。 Domtar 开发了一种具有高流体动力比表面积的特殊纸浆并获得了专利，该纸浆具有最小的纤维长度损失和较低的细粉产量。 Innofibre 之前对表面增强纸浆纤维 (SEPF) 进行了研究，并证明了当添加到其他纸张等级中时，纸浆作为纸张增强材料的潜力。纸浆脱水能力限制了其生产和商业化。脱水再制浆后，纸浆性能受到影响，纸浆的潜在用途明显下降。该项目将能够了解实验室规模脱水（包括机械除水和传热脱水）对纸浆的脱水效果。使用实验设计优化中试规模脱水技术将为 Domtar 提供所需信息，以植入适合 SEPF 的最有益的脱水系统。因此，Domtar 将能够进一步开发 SEPF 的使用和商业化，并继续保持加拿大、北美乃至世界纸浆制造商的领先地位。
