| 摘 要： | 速生杉木通过浸渍PF树脂并压缩改性后,力学性能得到大幅度提高,且随着树脂浓度和压缩率的增加而提高。增重率与真空度、浸渍压力、时间有关,并随着其增加而增大;抗胀(缩)率和阻湿率与树脂的浓度有关,当树脂浓度从0上升到10%时,ASE和MEE的值变化较大,当树脂浓度超过10%后趋于平缓;在树脂浓度相同的情况下,较大压缩的恢复率也相应较大,当树脂浓度低于10%时,随着浓度增加,恢复率急剧下降,浓度达到15%以上时,恢复率几乎没有变化。

| Abstract: | Physical-mechanical properties of fast growing fir wood can be improved greatly after being im- pregnated with PF resin and compressed.Experiment results showed:mechanical properties of treated wood im- proved with the increase of concentration of the PF and compression ratio;weight percent gain(WPG)of treated wood increased along with the raise of degree of vacuum,impregnation pressure and time;anti-shrink efficiency (ASE)and moisture excluding efficiency(MEE)were related to concentration of the PF,variations of ASE and MEE were great as the concentration increased to 10% from 0,and were gentle when the concentration was o- ver 10%;under the condition of equal concentration,higher compression led to higher recovery ratio;the recov- ery ratio decreased quickly with the increase of concentration of PF resin when the concentration was lower than 10%,while it had no change almost when the concentration exceeded 15%. |
