Abstract

A procedure was developed to observe the water absorption characteristics of small specimens of oriented strandboard (OSB) and solid wood in a nuclear magnetic resonance (NMR) microimaging facility. The procedure allowed a specimen to be surrounded in water while remaining in a fixed position within the imaging coil, after which the water could be removed and the specimen immediately imaged. This technique permitted images of the specimen to be taken after a number of different periods of water soak without having to remove and replace the specimen, thus easily maintaining the same image location. Both the distribution of free water and its movement as a function of time were observed using this technique. Inter-strand voids within OSB were shown to be the main route for moisture movement through a specimen of this type. The influence of the inherent anisotropy of OSB on moisture movement was investigated by sealing selected surfaces of a specimen with silicone to observe moisture absorption in predetermined directions.
