摘要
对建筑用聚氯乙烯(PVC)塑料管材进行人工耐候老化测试,得到几组老化后拉伸强度数据,利用非线性回归法,得到相应的老化试验预测数学模型,经与试验数据比较,该预测模型的误差范围在-5.2%～2.7%。
The aging tensile strength data of PVC plastic pipe for architecture use were obtained after artificial weathering resistance test. The corresponding aging test forecast mathematical model was made using nonlinear regression method. After comparing with test data, the error limit of forecast model was from -5.2% to 2.7%.
