Abstract
To determine the depth of preservative penetration in ACQ treated wood, the degree of penetration of Cu was measured. In this study, we developed a DDAC coloring method to investigate the penetration depth of DDAC, which is one of the active ingredient of ACQ, into wood. The following conclusions were obtained. The DDAC component reacts with a 2', 7'-dichlorofluorescein indicator and results in a deep orange color. This orange coloring reaction appears not only in DDAC solutions but also in ACQ treated wood tissues in which DDAC is present. It is possible to visually verify that DDAC has better wood penetration than Cu in the spruce, which is an refractory wood species, by the DDAC coloring method developed this study. In addition to the results, it is necessary to investigate the difference in penetration of Cu and DDAC for other wood species with poor preservative penetration.
