摘要： A method to produce on a commercial scale, high aspect ratio cellulose nanofilaments (CNF) from natural lignocellulosic fibers comprises a multi-pass high consistency refining (HCR) of chemical or mechanical fibers using combinations of refining intensity and specific energy. The CNF produced represents a mixture of fine filaments with widths in the submicron and lengths from tens of micrometers to few millimeters. The product has a population of free filaments and filaments bound to the fiber core from which they were produced. The proportion of free and bound filaments is governed in large part by total specific energy applied to the pulp in the refiner, and differs from other cellulose fibrillar materials by their higher aspect ratio and the preserved degree of polymerization (DP) of cellulose, and are excellent additives for the reinforcement of paper, tissue, paperboard and the like. They display exceptional strengthening power for never-dried paper webs.

摘要： A method is proposed for improving pulp quality at high production rates on conical disc refiners. It permits a reduction in refining intensity by enabling fibre residence time to increase by increasing consistency, while avoiding the problem of plate plugging normally associated with high discharge consistency. In practice, inlet consistency is increased by the in-feed dilution, flat zone dilution or both, but without allowing the discharge consistency to rise. Instead, the discharge consistency is controlled at a fixed optimum value by the addition of dilution water within the conical zone. The result is that residence time is increased, and refining intensity decreased, by raising the consistency in the inner region of the refining zone, while avoiding the plate plugging caused by excessive consistency in the outer region of the refining zone.
摘要翻译：提出了一种在圆锥形精炼机上以高生产率提高纸浆质量的方法。它允许通过使纤维停留时间通过增加一致性而增加，同时避免通常与高排放一致性相关的板堵塞问题，从而降低精炼强度。在实践中，通过进料中稀释，平面区域稀释或两者均可增加入口稠度，但不允许排出稠度上升。相反，通过在锥形区域内添加稀释水将排出稠度控制在固定的最佳值。结果是，通过提高精炼区内部区域的一致性，同时避免由于精炼区外部区域的过度一致性引起的板堵塞，停留时间增加，精炼强度降低。

摘要： A method has been developed that estimates from the on line measurements of readily available process variables the proportion of the mass of fibre in the refining zone of a chip refiner relative to the mass with a full refining zone. This estimate of the filling factor is used to determine the margin available to load the refiner and the control action needed to avoid abnormal operation.

摘要： In the mechanical refining of wood chips to produce wood pulp, wood pulp quality is improved by employing low refining intensity at least in a final refining stage; the refining is carried out in a double disc refiner or a single disc refiner at rotational speeds that are lower than those conventionally employed, specifically at less than 1200 RPM in a double disc refiner and at less than 1500 RPM in a single disc refiner.
