Effects of best management practices on copper migration from Douglas-fir lumber treated with ACZA, CA or ACQ

Creator:

Ye, Min

Abstract:

Copper is the most common ingredient in waterborne preservatives and provides excellent activity against most fungi and insects. However, issues associated with copper migration from treated wood have created increasing concerns about potential risks to non-target organisms in surrounding environments, especially those in sensitive aquatic environments. Various Best Management Practices...

Supercritical fluid impregnation with biocides of wood using temperature reduction

Creator:

Kang, Sung-Mo

Abstract:

Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....

Pressure measurement in wood as a method to understand impregnation processes : conventional and supercritical carbon dioxide

Creator:

Schneider, Philip F.

Abstract:

Two approaches to improving wood treatability include the modification of pressure schedules during conventional liquid treatments and the use of supercritical fluids (SCFs). In both of these techniques, pressure differences are important for transporting materials into wood. The level of pressure and its change during SCF treatments are also important...
