RESULTS WITH AN OPTICAL MEASUREMENT METHOD TO DETERMINE THE AMOUNT AND SIZE DISTRIBUTION OF SCLEREIDS IN MECHANICAL PULP

摘要：

Sclereids (stone cells) are cells that form mainly in the bark of most softwood and hardwood trees. Sclereids are composed of dead cells with extremely thick secondary walls and because they are found in clusters that are typically much larger than single wood fibres they can cause significant problems on the paper machine, e.g. dusting, holes in the paper, calendar problems and printing problems. Results of a plant profiling using a novel optical measurement method to determine sclereid size distribution are shown. With this new method the effect of refining, screening and reject cleaning on the size distribution of sclereids can be determined.
