中文摘要:
      对载重子午线轮胎285/75R24.5和轻载子午线轮胎185/80R14C进行了硫化测温试验。测温结果表明,载重子午线轮胎带束层区域易欠硫,胎面区域易过硫;轻载子午线轮胎胎圈区域易欠硫,胎体和胎面区域易过硫。硫化后冷却时的后硫化效应对总硫化程度影响很大,尤以轻载子午线轮胎为甚。可以通过合理调整硫化时间和温度改善轮胎整体硫化程度。
英文摘要:
      The temperatures in 285/75R24.5 radial truck tire and 185/80R14C radial light truck tire were measured during vulcanization.The results showed that the belt area in radial truck tire was subjected to be undercured and the tread area was subjected to be overcured;and the bead area of radial light truck tire was subjected to be undercured and the carcass and tread areas were subjected to be overcured.The post-cure effect gave a great influence on the total curing state of radial tire,particularly radial light truck tire.The total curing state of tire could be improved by adjusting the curing time and temperature reasonably.
