The tribological problem in natural sand dust environment was proposed and an equipment for simulating the natural sand dust environment based on Multi-Venturi structure was introduced for studying the tribological problem. The wear performance of polymer tapes in sand dust environment was evaluated by using a roller-scraper tribosystem. Three typical wear models including cutting, wedge forming and ploughing during the intrusion of sand particle into the contact interface of polymer materials were found. The abrasive wear mechanisms were discussed with particle intrusion mechanism.
