马来酸酐对神府煤液相研磨接枝改性的研究

Study of maleic anhydride graft on Shenfu coal by grind in solution

为了加强神府煤的材料化利用 ,对马来酸酐的液相接枝改性神府煤进行了研究。研究发现 :随着接枝时间的增加 ,接枝率逐渐增加 ;随着马来酸酐的增加 ,接枝率也逐渐增加 ,但当马来酸酐 /神府煤质量比增加到1 8/ 5时 。

In order to broaden the material utilization of Shenfu coal,using maleic anhydride to modify Shenfu coal is studied.The result showed that the rate of graft is increased with the increase of graft time and the weight of maleic anhydride,but when the weight ratio of maleic anhtdride/Shenfu coal is 1.8/5,the rate of graft tend to stable.
