2. [Article] Internal pressure measurement techniques and pressure response in wood during treating processes
The development of pressure inside wood during preservative impregnation was studied using Douglas-fir heartwood and ponderosa pine sapwood. Pressure sensors mounted on sample holders provided the most ...Citation -
3. [Article] Supercritical carbon dioxide treatment: Effect on permeability of Douglas-fir heartwood
The effect of supercritical fluid treatment on superficial gas permeability of Douglas-fir was investigated by using carbon dioxide either alone or amended with methanol. Permeability increased in a majority ...Citation -
4. [Article] Supercritical fluid (SCF) treatment: Its effect on bending strength and stiffness of ponderosa pine sapwood
Adverse effects on mechanical properties from using a supercritical fluid (SCF) to increase preservative penetration of refractory woods were evaluated by treating small ponderosa pine sapwood specimens ...Citation -
5. [Article] Effects of supercritical fluid treatments on physical properties of wood-based composites
The effects of supercritical fluid (SCF) impregnation on physical properties of composites were investigated at various pressures, temperatures, and treatment times with carbon dioxide as the fluid and ...Citation -
6. [Article] Effect of process variables on supercritical fluid impregnation of composites with tebuconazole
This study examines the effects of pressure, temperature, and treatment time on supercritical fluid impregnation of such composites as plywood, particleboard, flakeboard, and medium-density fiberboard. ...Citation
