【摘要】 通过观察微米级粉体荷电后在有机液体中的分散效果,从而得到荷电量与分散性之间的关系。进而探索一种粉体在有机液相中的分散方法。对粉体进行荷电处理后,制成有机悬浮液,测量液体的透射率并进行比对,确定荷电量与透射率之间的关系。进而分析荷电量与分散性的关系。对荷电前后的粉体溶液进行对比, 其分散性有了不同程度的提高,并具有一定的稳定性。通过实验发现,利用简单的起电方法使粉体带电,可以不同程度提高在有机液体中的分散性。更多还原

【Abstract】 Through observation dispersivity of micro powder with different charge in organic solution,to obtains relations between the different charge of micro powder and the dispersivity,Then explores one method witch micro powder disperse in organic solution.Electrification on the micro powder and make the organic suspension,To measure transmission of organic suspension witch made of different electrification use spectrophotometer,then compare to different solution transmission,and confirm the ralation between transmission and different charge powder,and analyze ralation between dispersivity and electrification.Through contrast the powder solution around,dispersivity has the different degree enhancement,and has the certain stability.It can enhance the dispersivity in the organic solution witch use the simple method to electrify.更多还原
