| 中文摘要: |
| 分析导电轮胎烟囱胶缺陷的产生原因并提出相应的解决措施。预口型形状设计不合理、口型板底板倒角宽度设计偏大、烟囱胶预口型出口宽度设计不合理、烟囱胶门尼粘度偏低、现场管控不到位等均会导致烟囱胶不外露。通过调整烟囱胶口型和预口型形状、改善胶料的门尼粘度、加强现场管控等措施，可解决烟囱胶不外露问题。 |
| 英文摘要: |
| The reasons of defects of conductive tire chimney rubber were analyzed and the corresponding solutions were proposed.Unreasonable design of the preformer shape，too large design of the chamfering width of the bottom of die plate，unreasonable design of the outlet width of preformer of chimney rubber，low Mooney viscosity of chimney rubber，and poor on-site control would all caused the chimney rubber to not be exposed.By adjusting the die and preformer shape of chimney rubber，improving the Mooney viscosity of the rubber compound，and strengthening on-site management and control，the problem of the chimney rubber not being exposed could be solved. |
