Insight into property development of LC- refined NBSK and its mixtures

自然资源的收获是加拿大经济繁荣的支柱。没有活的果肉， 造纸业，不可能有一个可行的林业。传统上，BC省和加拿大的纸浆和 造纸部门针对美国市场的通信纸。最近的经济衰退，加上 无纸化通信的颠覆性技术，使新闻用纸减少了40%， 通信用纸消费。这一转折点意味着林业的生存取决于 加拿大开发高质量北方漂白软木牛皮纸（NBSK）的创新用途的能力 纤维. 纸浆行业正在积极开发NBSK通信纤维在全球的新市场 纸张、包装、卫生产品和新的应用。这种纸浆常用于增强纸浆的强度， 含有机械纸浆或南方气候中生长迅速的短纤维的纸制品。一个关键 造纸商使用NBSK的操作是精制--一种刚好在造纸之前的机械处理。 如果操作正确，纸浆质量将大大提高;如果操作不当，纸浆质量可能会保持不变 未开发因此，必须向论文编制者提供关键知识和指导方针， 如何最好地精炼NBSK纸浆，单独使用，或与短纤维混合使用。不幸的是， 在某些关键方面，该领域受到限制。同样缺乏关于NBSK如何增强纸浆强度的知识 混合物。这项研究的目的是填补这些知识的关键空白。

The harvest of natural resources is the backbone of a thriving Canadian economy. Without a viable pulp and paper industry, it is not possible to have a viable forestry industry. Traditionally, BC and Canada's pulp and paper sector targeted communications papers in the US market. The recent economic downturn, coupled with disruptive technologies for paperless communication, has resulted in a 40% reduction in newsprint and communication paper consumption. This turning point means that the forest industry's survival depends on Canada's ability to develop innovative new uses for high quality Northern Bleached Softwood Kraft (NBSK) fibres. The pulp sector is actively developing new markets around the world for NBSK fibre in communication papers, packaging, hygiene products, and novel applications. This pulp is often used to enhance the strength of paper products containing mechanical pulps or short, fast-growing fibres from southern climates. A key operation in the use of NBSK by papermakers is refining-a mechanical treatment just prior to papermaking. When done correctly, pulp quality is greatly enhanced; when done poorly, pulp quality may remain undeveloped. It is therefore imperative that papermakers be provided with the key knowledge and guidelines on how to best refine NBSK pulps, alone, or when mixed with short fibres. Unfortunately, knowledge in this field is limited in some key aspects. Similarly lacking is knowledge on how NBSK reinforces strength of pulp mixtures. The objective of this research is to fill these critical gaps in knowledge.
