Abstract
The effects of pressure and temperature on supercritical fluid impregnation of tebuconazole were evaluated on Douglas-fir, western red cedar, red alder, white spruce, and white oak. Higher pressure markedly enhanced both the retention and distribution of tebuconazole in these species. When the rate of pressure release was altered at the ends of treatments of Douglas-fir, results varied. Generally, a higher rate of venting increased the steepness of the preservative gradient inward from the surface. Elevated pressures also affected some wood properties. Western red cedar and white spruce showed collapse, while the other three species were free of such defects. Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) tended to decline with higher pressure in western red cedar and white spruce, but the differences were rarely significant. No significant changes in MOE/MOR occurred with the other 3 species.
