Comparison of Temporal Changes in Metal Leaching and Aquatic Toxicity from Wood Treated with CCA and Alternative Preservatives
2005 - IRG/WP 05-50236
This study compares the temporal variation of chemical leaching and aquatic toxicity of wood treated with chromated copper arsenate (CCA) and other copper-based wood preservatives (alkaline copper quaternary (ACQ), copper boron azole (CBA), copper citrate (CC) and copper dimethyldithiocarbamate (CDDC)). Treated wood blocks were leached for 21 days and the leachate collected was analyzed for prese...

Effects of sodium hypochlorite on compression strength and copper retention of spruce wood treated with copper azole and alkaline copper quat
2007 - IRG/WP 07-40362
This work investigates the effects of sodium hypochlorite on compression strength values and copper retention ratios of refractory spruce wood (Picea oriental L.) treated with the waterborne preservative Copper Azole, (CBA-A, Tanalith-E 3492) and alkaline copper quat (ACQ-2200). Before the copper azole and alkaline copper quat treatment, the samples were immersed in 500 ml of sodium hypochlorite s...

Effects of acetic acid and nitric acid pre-treatment on copper content of spruce wood treated with CBA-A and CCA
2008 - IRG/WP 08-40406
This work investigates the effects of nitric acid and acetic acid on compression strength values and copper retention contents of refractory spruce wood (Picea oriental L.) treated with the waterborne preservative Copper azole, (CBA-A, Tanalith-E 3492) and copper / chrom / arsenic (CCA). Before the CBA-A and CCA treatment, the samples were immersed in 500 ml of nitric and acetic acid solutions for...

Effects of planning and sanding on penetration and retention properties of some softwood species treated with copper azole
2008 - IRG/WP 08-40410
This work investigates the effect of some woodworking treatments on penetration and retention properties of four different (scotch pine—SP, Siberian scotch pine—SSP, Siberian larch—SL, and oriental spruce—OS) heartwood species with the waterborne preservative copper azole (CBA-A). A 2.4% active ingredient solution of CBA-A was applied for use in vacuum/pressure treatment of the heartwood s...

Resistance to Decay Fungi of Scots Pine Impregnated with Natural and Chemical Preservatives
2014 - IRG/WP 14-30650
In this study, heart-wood and sap-wood specimens of the Scots pine which is naturally grown in Turkey were treated with natural (valex) and some chemical preservatives such as CCA - C (Copper / Chrome / Arsenic), CBA - A (Copper / Boron / Azole). The wood protective efficacies of these preservatives were investigated by means of fungi decay test (EN 113). As a result of the study it was found t...
