摘要
分析全钢载重子午线轮胎胎圈气泡的产生原因并提出相应改进措施。施工设计及半成品尺寸不当、排气线完整性差、成型贴合压辊位置不合理及硫化模具钢圈排气线不通等均会导致胎圈气泡缺陷。经过优化施工设计、增加胎侧及加强层刺孔工艺、规范半成品尺寸过渡及成型辊压等措施能够有效减少胎圈气泡的产生,提高轮胎合格率。
The causes of bead bubbles of truck and bus radial tire were analyzed and corresponding improvement measures were put forward.Improper construction design and semi-finished product size,poor integrity of the exhaust line,unreasonable position of the building and laminating rollers,and unreasonable exhaust line of the steel ring of curing mold all led to the defect of bead bubbles.By optimizing the construction design,increasing the puncture process of the sidewall and reinforcement layer,standardizing the size transition of semi-finished products and the rolling process of the tire building,the defects of bead bubbles could be effectively reduced,and the qualification rate of finished tire could be improved.
