研究了环境温度、结皮层对PVC/木粉发泡制品温度分布的影响,并测试该温度分布下,制品力学性能的变化。试验结果表明：上面的环境温度对制品温度的分布影响较大；制品表面结皮层能够加快热量的传导,从而使得制品温度分布上升；制品温度分布对力学性能有影响。通过公式拟合,可以计算得到在表面环境温度为90℃,底面环境温度为40℃下,制品的弯曲模量；该计算值与实测值相当。
This paper studied the influence of environmental temperature and crusts on temperature distribution of PVC/wood foaming products. The test results showed that:the effect of the above temperature on the product dis-tribution of temperature was remarkable;surface crusts could accelerate the conduction of heat,so that the product distribution of temperature rose;temperature distribution had influence on the mechanical properties. Through the fitting formula,we could obtain bending modulus of products. The calculations are in good agreement with measured value.
