Tb104: An Analysis Of Moisture Content Variation In Eastern Spruce And Balsam Fir In Maine, James E. Shottafer, Allen M. Brackley
Technical Bulletins
This study was undertaken as an attempt to develop some estimate of the characteristic moisture content of green eastern spruce (Picea spp.) and balsam fir (Abies balsame a (L. ) Mill.), employing the methods prescribed under the Maine Weights and Measures Law. Certain procedural factors and conditions of growth were also considered, to evaluate their effect on the moisture content of the wood at the time of harvesting or shortly after cutting.

Technical Bulletins
A standard urea-formaldehyde liquid adhesive was used in the manufacture of eastern spruce flakeboard panels. The resin application system, resin viscosity, furnish moisture content, and application period were all conducive to the formation of a fine resin spray. The average resin droplet diameter was approximately 20 microns, while the average resin are a coverage, over the entire wood furnish, was 8.05%. Resin distribution in the microscopically observed panel specimens appeared in the form of “spot-welds” and intermittent glue lines. The use of various histological and commercial stains was effective in producing decorative panels.
