Movement of water through quaternary ammonium treated wood
P J Hayward, J Duff
Radiata pine sapwood stakes were treated with didodecyl methyl 1, 3 dichloropropenyl ammonium chloride and distearyl dimethyl ammonium chloride. Various ratios of these two chemicals were, tested to determine the extent of water movement through the treated wood. Measurements were taken of the amount of water moved through the wood, degree of wetting of various sectors of the stakes, and the distribution of the quaternaries through the stakes. The results showed that didodecyl methyl 1,3 dichloropropenyl ammonium chloride increased the amount of water movement through the stakes compared to untreated, however the addition of distearyl dimethyl ammonium chloride reduced the water movement to below that of untreated. Over the twelve weeks of the trial no redistribution of quaternaries was noted.
