| 中文摘要: |
| 由微观和唯象分析建立了橡胶粘附摩擦的理论模型。通过对模型的分析和试验验证，提出了提高密炼机混炼效果的新途径：（1）密炼机温度控制采用温水冷却，使密炼机处于最佳工作状态；（2）通过合理选择密炼室和转子表面材料以改变材料表面能来增大胶料与它们之间的摩擦力；（3）在压砣压力较大的条件下，在密炼室内壁沿与转子轴线同方向加工浅的光滑槽，可明显改善混炼效果。 |
| 英文摘要: |
| A theoretical model of rubber adhesion friction has been developed based on the microscopic and phenomenological analysis.By analysing and verifying the model experimentally,some new ways for improving mixer performance have been provided:a)warm cooling water should be used in the mixer temperature control to make the mixer work under optimum conditions;b)the surface materials of mixing chamber and rotors should be rationally chosen to change material surface energy and increase friction force on them;c)when the compound is processed under higher ram pressure,shallow g rooves or stripes should be made on inner mixing chamber wall and in the same direction as that of rotor axis to increase the real contact area and improve the mixing effect . |
