氧化作用对烟煤胶质层指数稳定性的影响研究

Study on the effect of oxidation on the stability of bituminous plastometric indices

以煤样接触氧气的时间作为表征指标,选用常规包装和除氧包装2种不同的贮存方式,以低、中、高3个不同量值的烟煤样品为例,定量地阐述了氧化作用对烟煤胶质层指数稳定性的影响,初步分析了烟煤胶质层指数标准物质研制的可行性。

The time of coal sample contacting oxygen was used as the characteristic index in the paper. Two different storage pattern, normal packaging and deoxidation packaging, was plastometric indices was quantitatively described by use of three The feasibility of developing the certified reference materials preliminary analyzed in the paper. chosen. The effect of oxidation on the stability of bituminous different bituminous coal samples with low, middle and high value. for the determination of bituminous plastometric indices was also
