| 中文摘要: |
| 用硅烷偶联剂KH-570改性Al2O3粉体.结果表明:通过对Al2O3粉体在水-油体系中的分散状态观察发现,改性后的Al2O3表面由亲水性变为亲油性;通过红外光谱(IR)分析可知,KH-570与Al2O3粉体表面发生了化学键合;经扫描电镜(SEM)观察到改性后的Al2O3粉体不再团聚在一起,得到了有效的分散. |
| 英文摘要: |
| Al2O3 powders are modified by surfactant KH-570. The results show that Al2O3 hydrophilic surface has been transferred to hydrophobic via modification by observing its dispersive state;chemical bond combination happens between KH-570 with Al2O3 powders surface by IR analysis;it is observed by SEM that Al2O3 powders modified are not agglomerated. |
