分析全钢载重子午线轮胎胎面挤出过程中胎冠胶与基部胶脱层问题。通过调整口型和预口型尺寸、进一步优化开型因数以及冠胶和基部胶出胶比例等措施,胎面挤出脱层质量缺陷明显减少,返回胶量减小,胎面生产成本和能耗降低。 The problem of delaminating tire tread rubber and base rubber during the tread extrusion process of all-steel radial truck tires was analyzed. By adjusting the size of the mouth and the pre-mouth, to further optimize the open-type factor and the ratio of the top plastic and the base plastic, the quality defects of the tread extrusion delamination are obviously reduced, the return glue amount is reduced, the cost of the tread production and energy Reduce consumption.
