The freezing of coal in transit is a serious problem for the coal industry. The most promising preventive method is to reduce the pour point of the moisture's active component and reduce the strength of the bonds in the frozen coal. The materials employed should be harmless to the operating staff and the environment, should not cause corrosion of metal components, should not impair coal quality, should not significantly reduce the capacity of the rail car, should not require special storage conditions, and should mix well with coal. This work is continuing the search for new reagents to prevent the freezing of coal in winter. Attention focuses on the physicochemical characteristics of acetates of alkaline-earth and alkaline metals and silicone polymer, methods of introduction in coal concentrate, and influence these reagents on freezing. The results of studies have shown that the use of organosilicon is a more effective use of acetates and chlorides of metals. The high activity of organosilicon substances is explained by their elemental composition and structure of molecules. [ABSTRACT FROM AUTHOR] |
