Effect of the Chemical Treatment on the Carbon Fixation of Wood

The objective of this study was to evaluate the effect of the chemical treatment on the carbon fixation of wood, including ammoniacal copper quats (ACQ) and Dricon. Tested specimens were respectively impregnated with ACQ solution at 0.5, 1, 2, 4, 6% w/w and with Dricon at 1, 2, 4, 6, 12% w/w. Fungal decay resistance and fire retardancy of the treated wood were evaluated according to ASTM standard showed less weight loss than the threshold retention of 2% and were also effective in resisting attack by brown fungus-Gloeophyllum trabeum. However, the threshold retention for weight loss of 2% against whiteD1413-99 (1999), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Results revealed that wood specimens of Cunninghamia lanceolata and Cryptomeria japonica with 0.5% ACQ fungus-Trametes versicolor was observed when Liquidambar formosana wood treated with 2% of ACQ. The effects of the increase in carbon retention and the reduction in the retention of carbon dioxide release in wood were significantly improved by treating with ACQ. The reaction mechanism of burning changed, when Cunninghamia lanceolata, Cryptomeria japonica and Liquidambar formosana were treated with Dricon, and better results in carbon retention and the reduction in the release retention of carbon dioxide for Dricon-treated wood were observed when treated with higher concentrations of chemicals.
