Previous studies have shown that cold temperatures slow the fixation reaction, extending it to several weeks [8,15], so that the short delay prior to examining the RE heating would have little impact on the accelerated fixation.
Following completion of RF heat treatment, the core of the pole section retains considerable heat that can be used to complete the fixation reaction. To test this potential, some experiments were conducted using one Douglas-fir, two red cedar, and four red pine pole sections.
Recent research indicates that the ACQ-D is relatively leach resistant because of chemical fixation reactions within the wood which occur rapidly--within hours--after treatment.
