中密度纤维板内结合强度检测研究

摘要

The influence on IB test results of the number of universal joint and the interval from test sample adhering to clips and clips temperature reaching (20±2)℃till the start of the IB test. The results showed that the number of universal joint had certain effect on the IB, and the IB was biggest when 2 joints were used. As the interval prolonged, the IB increased first, then decreased to a stabilized value, and maximum value of the IB occurred at 1 h from test beginning.%分析比较了中密度纤维板试件在检测时所用万向节数量和试件与卡头胶结后多长时间进行检测对内结合强度测试结果的影响,试验结果表明:使用万向节对内结合强度的测试值有一定的影响,使用两个万向节的内结合强度测试值比用一个和不用要大;从卡头的温度达到环境温度(20±2)℃开始计时,随着时间的增加,内结合强度的测试值先增大且在1h时达到最大值,然后逐渐减小,最后趋于恒定.
