F. R. Stellenbosch University. Faculty of AgriScience. Dept. of Forest & Wood Science. Wood-pulp Sulfate pulping process Wood chips Dissertations -- Wood science Thesis (M. Sc.) -- University of Stellenbosch, 1996. The importance of chip thickness for uniform delignification and reduced carbohydrate losses is common knowledge in alkaline pulping. The observed effect of chip thickness relates to pulping rates that become diffusion limited at higher chip thickness. The critical thickness below which diffusion is no longer a factor depends on the specific wood characteristics that include extractive contents, and the pulping process being used. The possibility also exists that chip thickness together with extractive content could have synergistic effect on reject formation. It might therefore be advantageous for pulp makers to adjust their chippers to produce thinner chips, when pulping wood with a high extractive content.
