摘要
煤炭是一种具有大分子网状结构的有机岩石 ,表面润湿性是其工业应用的重要物性参数 .通过原煤及分别经过偶联剂和烷基化处理的煤样表面润湿性的测定 ,对煤表面润湿性进行了初步研究 .结果表明 ,分别经过偶联剂处理和烷基化处理的煤样 ,其润湿性有一定程度的改善 ,使煤样表面发生了改性 。
Coal is a kind of organic mineral with macromolecular network structure. The coal surface humidity is an important parameter in the field of industrial application. In this paper, the coal has been treated with coupling reaction and alkylation, the surface humidity of both rough and pretreated coal has been tested. Results show that the surface was modified and the surface humidity has been improved greatly through pretreatments, which are also proved by the FTIR spectrum analysis.
