The purposes of this study are to establish the standard impregnation manual of CCS preservative as post-CCA, to develop the quick measurement system of K value, to improve the penetration ability of CCS into the full-sized timbers, to evaluate the long-period antibiodeterioration effects of the treated woods, to estimate the chemical stability of the preservative, and to carry out the preliminary evaluation of poisons of the preservative. The outline of the obtained results is as follows.1)CCS preservative was able to use with the same as the handling manners of the commercially distributed water-soluble metal-preservatives.2)K values were easily measured applying by the conventional image analyzing techniques3)Penetrating ability of CCS into the full-sized timbers was improved by modifying molecular weight of CCS or combining PEG to CCS molecules, however, there was no change in fixation ability of the modified CCS.4)Wood-pegs impregnated with CCS showed amazing effects against termites and fungi5)during whole period exposed for six years.6)CCS preservatives showed good stability for five-time recycling use in treatments.7)CCS preservatives showed no signs of poison against rats.

本研究的目的是建立CCS防腐剂后CCA标准浸渍手册，开发K值快速测定系统，提高CCS对木材的渗透能力，评价处理后木材的长期老化劣化效应，评价防腐剂的化学稳定性，并对防腐剂的毒性进行初步评价。结果表明：1）CCS防腐剂可以与市售的水溶性金属防腐剂的处理方式相同地使用; 2）利用常规的图像分析技术可以很容易地测量K值; 3）通过改变CCS的分子量或将PEG结合到CCS分子中可以提高CCS对全尺寸木材的渗透能力，但是，结果表明：CCS对木材的固定能力无明显影响; 4）CCS处理木钉在6年的暴露期内对白蚁和真菌有显著的抑制作用; 6）CCS防腐剂在处理过程中5次循环使用稳定性良好; 7）CCS防腐剂对大鼠无毒性反应。
