针对较大尺寸圆筒模具内填充的丁苯橡胶的硫化过程，提出了硫化程度的预测方法。一维瞬态传热的热传导方程与橡胶的固化动力学耦合。引入热生成项，表示为固化速率和由于固化反应产生的总热量的函数，以解释过程中释放的热量的影响。研究了两种模具温度控制的实验方法。一是在恒定温度下继续加热，直到观察到橡胶上的均匀温度分布。另一种是在形成均匀的温度分布之前切断加热，以研究余热对固化过程的影响。两个实验固化数据集可以通过本发明的预测方法关联到平均绝对偏差11.5%。
A prediction method of the degree of cure is presented for the curing process of styrene-butadien rubber packed in a cylindrical mold with relatively large size. Heat conduction equation for one-dimensional, transient heat transfer is coupled to the cure kinetics of the rubber. Heat generation term, expressed as a function of the cure rate and the total heat generation due to the cure reaction, is introduced to account for the effect of heat liberated during the process. Two experimental methods for the mold temperature control are examined. One is that the heating is continued at a constant temperature until the uniform temperature profile across the rubber is observed. The other is that the heating was cut off before the uniform temperature profile was formed in order to study the effects of residual heat on the cure process. The two experimental cure data sets can be correlated by the present prediction method to a mean absolute deviation of 11.5%.
