摘要

为了改善竹材及竹制品防霉和防蓝变性能,同时提高竹材尺寸稳定性,以低分子量不饱和酸、脂溶液为塑化改性剂,通过真空加压浸渍处理工艺进行竹材改性处理,并对竹材的物理、力学及防霉性能进行测试。结果显示,改性后竹材的一次增重率达25.6%:尺寸稳定性和顺纹抗压强度大幅提高:对霉菌及蓝变菌的防治效力达100%。

Abstract

In order to improve mold resistance and dimensional stability of bamboo and bamboo products,Moso bamboo samples were treated with a compound plasticizer containing low molecular weight unsaturated acid and ester by a vacuum-pressure impregnation process. Weight percent gain（WPG）,dimensional stability, mechanical performance and mold resistances of the samples were then tested.The results showed that average WPG was 25.6%; the dimensional stability and compression strength parallel to the grain improved and mold and stain fungi resistance nearly reached 100%.
