Abstract

Deposition of small adhesive particles, called microstickies, onto pulp processing equipment and paper machines causes quality and operational problems for recycling mills. The factors that control deposition of microstickies onto surfaces of metal parts remain unclear. In this work, aluminum surfaces with a range of surface roughness were exposed to slurries containing micros-tickies. The deposition results showed that flat surfaces promote the aggregation and deposition of microstickies particles. Uneven surfaces tended to favor deposition of smaller microstickies, 0.2–1 μm, which may be related to greater contact area presented by the rougher surface. This work provides insights into the deposition of microstickies.

金属表面形貌对造纸白水微胶沉积行为的影响
在纸浆加工设备和造纸机上沉积的小粘性颗粒(称为微粘性)会给回收厂带来质量和操作问题。控制金属零件表面微粘沉积的因素尚不清楚。在这项工作中,具有一系列表面粗糙度的铝表面暴露于含有微粘性物的浆液中。沉积结果表明,平坦的表面有利于微粘微粒的聚集和沉积。不平整的表面有利于沉积较小的微粘性(0.2-1 μm),这可能与较粗糙的表面产生较大的接触面积有关。这项工作提供了对微胶沉积的见解。
