| 摘 要： | 为研究CCA防腐剂的固定性能,用银杏,欧洲赤松,山毛榉和牡竹进行比较试验。根据德国标准(DIN 52172Ⅱ-1977),试验设置1周、2周和4周的不同处理。对于Cu来说,处理后1周就已经固定得很好,流失量在各树种间无甚区别。而Cr的固定较慢,且各树种间差别较大。处理4周后,Cr仅在欧洲赤松中完全固定,在银杏和山毛榉中Cr的固定较好,而牡竹的Cr流失量仍为4％。

| Abstract: | The fixation of a CCA-preservative, type B in Ginkgo, scotch pine, beech and bamboo has been tested in comparative laboratory investigations according to the German standard DIN 52 172 part 2(1977), 1, 2 and 4 weeks after impregnation.Copper showed high fixation in all timber species already 1 week after impregnation whereas the fixation of chromium was slower and varied for the various species.After 4 weeks complete fixation of chromium took place only in pine.In beech and ginkgo the chromium was fixed to a higher extend whereas for bamboo about 4% of the chromium content was leached. |
