| 中文摘要: |
| 应用传热学原理研究分析了轮胎硫化过程中的热传递，指出了分段硫化的优点，并探讨了热扩散系数对橡胶硫化程度的影响以及影响热扩散系数的因素。结果表明，热扩散系数降低时制品的硫化时间延长；而胶料中炭黑用量在25～40份范围内时，炭黑用量每增大1份，则胶料的热扩散系数增大约5%。 |
| 英文摘要: |
| The heat transfer during the tire vulcanization was analyzed based on the heat transfer principle，the advantages of multi-stage vulcanization were pointed out，and the effect of the heat diffusivity on the curing state of rubber and the effective factors on the heat diffusivity were investigated. The results showed that the curing time of product extended when the heat diffusivity decreased；the heat diffusivity of the
compound，in which the addition level of carbon black was in the range of 25～40 phr，increased by 5% as the addition level of carbon black increased by every 1 phr. |
