| 摘 要： | 为了了解橡胶厚制品硫化过程中各部位的热历程，采用了直接测量法，即将测温热电偶埋设于制品的指定位置以测量其温度变化，然后用相对硫化速率表求得各部位在不等温硫化过程中对应于基准温度下的等效硫化时间，并与相应半成品基准温度下的正硫化时间进行比较，用以分析其实际硫化程度。采用此方法对某些厚制品进行了实际测量，发现测量结果可以反映实际情况，并可对提高制品质量提供十分有益的指导和帮助。

| Abstract: | A direct measurement used to determine the heat history at various parts of thick walled rubber article during vulcanization was proposed.The thermo couples were embedded in the specified parts to measure the changing temperatures there.The EV time relative to the standard temperature at said parts during anisothermal curing process was calculated with the relative curing rate table.Then the resultant EV time was compared to the optimum cure time of corresponding semi product at the standard temperature to obtain the practical curing state.It was found through the measurements of some thick walled rubber articles with the said method that the measuring results could reflect the reality during vulcanization. |
