Soil bed studies of the dimensional stability of composite products
K M Filcock, P Vinden
The influence of boron and isocyanate resin on the dimensional stability of high moisture resistant particleboard was assessed after burial in a soil bed for one month. The samples were treated with two levels of a boron compound and coated in isocyanate resin. The samples were randomly placed in a fungal cellar in soils of two different water holding capacities. Weight differences and dimensional changes were measured after one month. The results suggest that there is a significant increase in weight and thickness swelling. Boron treatment prior to resin impregnation also appears to have assisted moisture absorption.
