| Abstract: |
| A direct measurement used to determine the heat history at various parts of thickwalled 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. |
