摘要
进行了神府 3- 1 煤原位力化学改性超细活性粉体制备 ,并从吸油值、粒度特性两方面对粉体表面性质进行了表征。结果表明 :行星球磨进行神府 3- 1 煤的超细改性可行。不同系列偶联剂对改性效果影响不一 ,但都存在最佳剂量 ,为神府 3- 1
Analyzes the preparation of ultrafined and activated coal powder by means of in situ mechano chemical modification method. Then the powder surface properties are evaluated from DBP absorbency and particle size performance. The conclusions are reached that planetary ball milling is suitable to pulverization and modification of Shenfu 3 -1 coal. On the other hand, various couplers can lead to different modification effects, but they all have optimal dosage in this operation. It can provide instructive channel for material utilization of Shenfu 3 -1 coal.
