Abstract

This study examines how cellulose aging affects the degradation of dissolving pulp quality during storage. Dissolving pulp, with a consistency of 10%, is stored in tanks before being processed into pulp sheets. Over time, the quality of this pulp deteriorates, a phenomenon known as pulp aging. Key factors such as temperature and pH impact the rate of aging. To simulate this process, samples of 10% consistency pulp are placed in a water bath under storage-like conditions for 144 h, with pH levels adjusted to 4, 6, and 8, and temperatures set at 50 ℃, 60 ℃, and 70 ℃. The quality metrics analyzed include brightness and viscosity, assessed every 24 h. Findings indicate that the optimal storage conditions are at temperature 50ºC and pH 8, where the aging process and degradation in quality are slower. Under these conditions, the rate of aging is up to three times slower compared to the highest rate, which occurs at pH 4 and 70 ℃. These results provide valuable insights for optimizing storage conditions to preserve dissolving slush pulp quality.
