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%。
The vulcanization technology of 27. 00 R49 giant off-the-road radial tire was improved by using two temperature stage vulcanization process with both inner and outer heating. The inner hot water temperature changed from a single stage of 160 ℃ to the two stages of 173 and 140 ℃. The high and low temperature of outer steam was also adjusted from 145 and 130 ℃ to 135 and 125 ℃, respectively. The results showed that,after the improvement,the total curing time was prolonged by 20 minutes,the curing degree of tire decreased significantly,specifically,the curing degree of 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%.
