木材辐射接枝甲基丙烯酸甲酯的效果

Study on effect of grafting MMA into timber using irradiation

用 γ射线辐照研究了五种木材辐射接枝甲基丙烯酸甲酯的效果，以及３ 种辐照方式和辐射剂量对接枝增重率的影响⒚结果表明：五种木材的接枝增重率分别处在 ２３．６％ ～１６６．５％ 范围内， 其中杉木的接枝增重效果最好⒚辐照方式和辐射剂量对接枝增重效果有一定影响，浸水辐照有助于提高接枝增重率。

The effect of grafting MMA (methylmethacrylate) into five different timbers, the influence of three different methods and radiation dose on grafting yield were studied using γ irradiation. The results showed that the gratfing yields of five kind timber are between 23.6% and 166.5% respectively. Among them, the effect of China fir is the best. The irradiation method and radiation dose could influence on the grafting yield of timbers. The grafting yield of timber could be improved by the irradiation method with water. There was a positive relationship between grafting yield and radiation dose.
