中文摘要:
      对27.00R49巨型工程机械子午线轮胎进行双内/外温硫化工艺改进,其中内温由160 ℃单温硫化改为173/140 ℃双温硫化,高低温蒸汽温度分别由145和130 ℃改为135和125 ℃。结果表明:改进后总硫化时间延长20 min;轮胎硫化程度明显降低,其中轮胎硫化最薄弱点、轮胎胎侧外表面和轮胎内表面总硫化程度分别降低57%,32%和48%;轮胎TKPH值提升10.6%,室内耐久性能提升18.6%。
英文摘要:
      The vulcanization technology of 27.00R49 giant off-the-road radial tire was improved by using dual inner hot water(change from 160 ℃ single to 173 and 140 ℃ two steps) and dual outer steam(high and low temperature change from 145 and 130 ℃ to 135 and 125 ℃ respectively).The results showed that,after the improvement,the total curing time prolonged by 20 minutes,the curing degree of tire decreased significantly,and the blow point,the surface of the sidewall and inner surface of tire decreased by 57%,32% and 48% respectively,the TKPH value of tire increased by 10.6%,and the durability increased by 18.6%.
