摘要
改进发泡点分析仪(BPA)的胶料硫化程度(CD)计算方法。改进后计算方法为:根据胶料已知CD与硫化时间的Excel表,拟合一次函数或二次函数曲线,得出拟合方程式,采用拟合方程式计算胶料的CD。与改进前计算方法(以正硫化时间为基准)相比,改进后计算方法计算的胶料CD,尤其是发泡点CD准确性大幅提高。
The method of calculating the curing degree of rubber （CD） of the foam point analyzer （BPA） was improved. The relationship between CD value and curing time was established by the linear or quadratic function fitting based on microsoft excel for known data of CD value and curing time. Then the CD of test compound was calculated by using the fitted equation. The accuracy of result by using this improved method, particularly the CD value at foaming point, were greatly improved compared with regular calculation method which was based on the optimum cure time.
