Distribution of Borates around point source injections in dry wood members

摘要

Sometimes, field cuts of treated wood are required, with some wood species, these cuts expose untreated wood that is subject to attack by decay fungi, unless preservatives are applied to those surfaces. The objectives of this research were to determine at time of injection and 8 weeks after injection (1) the distribution patterns of water and several preservative solutions around points of injection in several wood species and (2) the influence of glycol on the initial distribution of injected borate solutions. Solid members of northern red oak, eastern cottonwood, southern pine, and laminated beams of red maple or Dougals-fir were used in this investigation.
