CC及ACQ-B防腐剂处理木材的抗流失试验

Leachability determination on Lumber Treaded with CC and ACQ-B

对于氨溶性季铵铜 ACQ- B处理的马尾松 (Pinus massoniana)及尾叶桉 (Eucalyptus urophylla)试材 ,在吸药量为 3.0～ 6 .0 kg/ m3时 ,按标准 AWPA M11- 87测定的流失率小于 2 .5 0 %。比较 ACQ- B与 CC两种处理材 ,当吸药量(以 Cu O计 )相当时 ,CC的流失率较 ACQ- B大。ACQ- B可用于与地接触的人工林木材处理 。

Leaching test was conducted according to AMPA M11 87 standard. Pinus massoniana and Eucalyptus urophylla were treated with ammoniacal copper quat type B (ACQ B), copper citrate (CC) and chromated copper arsente type C (CCA C). Leachability determination results showed that the leaching rate was less than 2.5% for the wood treated with ACQ B at the retention of 3.0～6.0 kg/m 3. The anti leachablitity of wood treated with ACQ B was better than that treated with CC, because the leaching rate of wood treated with ACQ B was lower than that treated with CC at almost same copper retention level (as copper oxide). ACQ B was a potential wood preservative for plantation wood used in the ground field such as agricultural and building wood.
