摘　　要：在5%～40%压缩率范围内的8种条件下,进行杉木压缩处理,分析处理材的渗透性与浸注性能。结果表明:1)压缩杉木的浸注量随着压缩率增大而增大,压力释放即时完成70%以上的浸注量,此后达到最大浸注量的时间,随着压缩率的增大而增加;2)压缩处理能有效改善杉木的渗透性,但压缩率对渗透性影响不显著;3)压缩处理杉木浸注性能的改善,是渗透性提高和可浸注空间增大的共同作用。在工业化生产中,可以通过压缩率来控制浸注量。Chinese fir samples were compressed with different compression ratios from 5%to 40%.Impregnation levels and permeability of the wood samples were tested to evaluate effects of the compression ratio on impregnation of the wood samples.The results showed:1)The impregnation amount of the wood samples increased as the compression ratio increased.It was also observed that the impregnation amount accounted for about 70%of the total impregnation amount when the compression was fully released.2)Permeability of the wood samples was improved significantly by compression with little effects on the compression ratio.3)Improvement of the impregnation resulted from increases of both permeability and wood space after compression.It was proposed that impregnation amount could be controlled with compression ratio in an industrial production.
