Effects of metal surface morphology on deposition behavior of microstickies from papermaking white water, TAPPI Journal July 2023

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 microstickies. 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.

Editorial: The innovation engine and the forest products industry value chain, TAPPI Journal October 2023

ABSTRACT: The forest products industry (FPI • pulp, paper, paperboard, building products, allied products, and byproducts) has been continuously innovating as it manufactures and delivers value-added products to consumers worldwide. Integrated pulp and paper mills produce pulp, paper, paperboard, and byproducts like turpentine, tall oil, methanol, lignin, and other chemicals.
