打浆度(或游离度)、静态滤水时间、动态比过滤阻力、滤水曲线是评价纸浆滤水性能的几种方法。从纸浆滤水性能研究的发展过程来看,建立能够全面反映纸浆滤水性能的评价方法及标准,不仅对理论研究有重要的意义,而且对生产实践有极大的指导价值。 Beating degree (or freeness), static drainage time, dynamic specific filtration resistance, and drainage curve are several methods to evaluate pulp drainage performance. From the development of research on pulp water filtration performance, establishing evaluation methods and standards that can fully reflect the performance of pulp water filtration not only has important significance for theoretical research, but also has great guiding value for production practice.
