以杉木为试材,以树脂型多功能改性剂(BLW)为改性剂,采用真空-加压-真空的浸渍方法,研究了初含水率对杉木浸渍增重率、改性固化增重率和改性材密度、含水率的影响。结果表明:随着初含水率的减小,杉木浸渍增重率和改性固化增重率都增大,最大值分别为215.99%和196.77%;浸渍材在干燥固化过程的逸散成分主要是水分和改性剂,逸散率在40.24%~19.22%范围内;在实验条件下建立了函数关系。
Using fir - like multi - functional modifier (BLW) as modifier and vacuum - pressure - vacuum impregnation method, the effect of initial water content on the rate of weight gain of Chinese fir, the weight gain of modified solidification Rate and modified material density, moisture content. The results showed that with the decrease of initial moisture content, the rate of weight gain of Chinese fir and the rate of modified weight gain increased, with the maximum values of 215.99% and 196.77%, respectively. The components of the impregnated wood during drying and curing were mainly Water and modifier, the fugacity is in the range of 40.24% ~ 19.22%; the functional relationship is established under the experimental conditions.
