将煤和改质剂共混压制成煤塑料板材,以此为样品和未经加工的原料混合样(对照样)分别进行吡啶抽提、热失重试验和差热分析,并作比较。试验结果表明煤和改质剂在共混工艺中不仅是物理混合,而且发生了化学反应。
The coal and modifier were blended and pressed into coal-plastic sheet to compare the pyridine extraction, TG test and differential thermal analysis for the sample and the raw material mixed sample (control sample) respectively. The test results show that the coal and the modifier are not only physically mixed in the blending process, but also chemically reacted.
