Water Absorption of Wood Composite Modified by Basalt Glass Powder

Abstract:

Moisture sorption of wood sawdust panel results in dimensional variation, deterioration of mechanical property and fungi attack, which may be improved by the reinforcement of waterproof material. In this study, the fir sawdust panel was reinforced by basalt glass particles with size smaller than 5 micron, in order to reduce moisture penetration. When the content of basalt glass powder was 15%, both the thickness swelling and 24 h water absorption rate of wood composites reached their minimum values, which were 2.7% and 11%, respectively. The thickness swelling was far smaller than the 45% upper limit of medium density fiberboard as described by standards GB/T17657-1999.
