采矿工业企业为了防止采掘物在金属容器内表面粘附和冻结,广泛采用尼奥格林、考斯和芦布斯—37(—67)等防冻剂,这些防冻剂可使露天矿运输设备的利用率提高6～17%。液态的化学隔离方法的主要缺点是吸附于金属内表面的薄膜的作用时间不持久,而且需要设置喷洒系统,反复对容器内表面进行喷洒,而且这种予防措施的费用很高。因此,提出用硬质聚合物衬板来代替液态化学隔离法的课题,以延长其使用寿命。
Mining industry enterprises in order to prevent the surface of metal containers in the metal surface adhesion and freezing, widely used noclio, Cowes and Rebus -37 (-67) and other antifreeze, these antifreeze can make use of open pit transport equipment Increase the rate of 6 to 17%. The main disadvantage of the liquid chemical isolation method is that the film adsorbed on the inner surface of the metal does not last long, and a spraying system is required to spray the inner surface of the container over and over again, and this preventive measure is expensive. Therefore, the problem of using a rigid polymer liner instead of the liquid chemical isolation method is proposed to prolong its service life.
