Effects of supercritical fluid treatments on physical properties of wood-based composites

Creator:

Acda, Menandro N., Morrell, Jeffrey J., and Levien, Keith L.

Abstract:

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 tebuconazole as a biocide. In general, within the ranges tested, SCF treatment had no negative effects on modulus of rupture (MOR), modulus...

Effect of process variables on supercritical fluid impregnation of composites with tebuconazole

Creator:

Acda, Menandro N., Morrell, Jeffrey J., and Levien, Keith L.

Abstract:

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. Carbon dioxide with methanol as a cosolvent was used as the supercritical fluid, with tebuconazole as the biocide. Biocide distribution, as measured by extraction and...
