18种树种木材防腐处理性能研究

对17种常用速生阔叶材及1种针叶材进行了可防腐处理性的试验研究，结果表明：阔叶材边材的质量载药量与它的密度呈极显著的线性关系。对其心材的防腐处理发现：各树种的心材渗透性能差异很大，只有马占相思、南洋楹、枫香、红锥、毛白杨和雷林1号桉等6个树种的心材可以完全渗透。湿地松和香樟木材不同体积试件的防腐处理，香樟的质量载药量随着试件体积的增大而减小的线性关系显著，而湿地松的质量载药量与试件体积却无明显的线性关系。

Treating Performance Study of 18 Species in Wood Preservation

Treating performance study of 17 commonly using hardwood species was conducted in wood preservation,the results indicated that,there was a linear relation between the air-dry density of sapwood and its mass retention.The permeability of heartwood of different species differs greatly.Only six species can be penetrated completely including Acacia mangium,Albizzia falcata,Liquidambar formosana,Castanopsis hystrix,Populus tomentosa,Eucalyptus leizhou No.1.Test blocks of different size were treated,the results showed that the mass retention of Cinnamomum camphora reduced while the volume of the test block increased,they had an obvious dependence relation.The mass retention of Pinus elliottii was not relevant with its test block volume.
