| Abstract: |
| The problems of conveyor belt running deviation and avultion caused by freezing adhesive turnabout roller surface seriously restricts the safe and efficient production of coal mines in cold regions during winter. The paper illustrated the occurrence mechanism of freezing adhesion, introduced the three existing Young, Wenzel, Cassie contact angle theoretical models, and briefly described the self-cleaning principle of super hydrophobic coating. The research status and preparation methods of super hydrophobic film in China and foreign countries in recent years were summarized, and the limitations of the super hydrophobic film preparation as well as the feasibility of application on turnabout roller were analyzed. Finally, the solutions to the problem of roller freezing adhesion were prospected. |
