Experiments on The Effect of Ultrasonic Energy on The Absorption of Preservatives By Wood


  • Stavros Avramidis


Preservatives, ultrasonic energy, CCA pentachlorophenol, creosote


The effect of ultrasonic energy on the absorption of CCA by spruce, Douglas-fir, and ponderosa pine, as well as the absorption of pentachlorophenol and creosote by the latter species was investigated at atmospheric pressure and 20 C temperature. The results showed an increase in the percentage uptake due to the effect of the ultrasound for all species and preservatives, with the only exception being creosote at immersion times below 30 minutes. The effect of ultrasound was more pronounced in more permeable species.
