针对煤与带式输送机改向滚筒表面的冻粘问题,设计了煤冻粘强度试验装置。模拟改向滚筒表面环境,在温度为-30℃和冷冻时间为3 h的条件下,研究了几种不同材料与含水率30%煤泥的冻粘特性。通过对比试验证明,UHMW-PE材料在法向、切向冻粘强度均比测试的其它材料低,说明了其具备良好的防冻粘能力;根据UHMW-PE包胶滚筒实际应用情况,进一步说明了可以利用UHMW-PE材料作为滚筒的涂层,以达到防冻粘的效果。
According to the freezing adhesion problem which exists between the coal and the belt conveyor turnabout roller surface,the freezing adhesive strength test device is created. To simulate the belt conveyor turnabout roller surface environment,- 30℃ temperature and 3h freezing time of stress conditions,several different materials are studied with moisture content 30% of the coal slime,each of the freezing adhesive characteristic. Comparative tests have proved that UHMW-PE material in normal,tangential freezing adhesive strength is lower than test of other materials,which proves that it is provided with good anti-freezing adhesive capability. According to UHMW-PE package roller based on the actual application situation can further illustrate that the UHMW-PE can be used as roller coating in order to achieve anti-freezing adhesive effect.
