Book Description
Several hardwood species have proven difficult to treat with wood preservatives, by either pressure or double-diffusion processes. Conventional double-diffusion methods have generally not worked as well with hardwoods as with softwoods. Modified double-diffusion methods, though, have proven useful in treating such species as Engelmann spruce, Rocky Mountain Douglas-fir, and several Alaskan species. These softwoods have been difficult to treat even by pressure. If successful, modified double-diffusion treatment of hardwoods could offer alternatives to pressure treatment, thermal treatment, and cold soaking for many species, and possibly offer better treatment for certain species. Most of the previous work using conventional double-diffusion with hardwoods used posts or material in the round form. This study has explored the feasibility of treating sawn hardwood stock with double-diffusion methods. Penetrations were observed by use of a chemical stain and retentions were determined by the assay of various zones. The data obtained provided guidelines for recommending treatment schedules.
