利用硅烷偶联剂KH-550对不同形貌Zr WMo O8进行表面改性,通过红外光谱(FT-IR)、接触角测试仪、扫描电镜(SEM)、X射线衍射(XRD)分析改性后Zr WMo O8的性能变化。结果表明,硅烷偶联剂改性后ZrWMo O8的晶体结构没有发生变化,但其接触角变大,疏水性增强,微粉团聚现象减少,分散性增强。 The surface modification of Zr WMo O8 with different morphologies was carried out by silane coupling agent KH-550. The modified samples were characterized by FT-IR, SEM, SEM and XRD. Change in performance of Zr WMo O8. The results show that the crystal structure of ZrWMoO8 modified by silane coupling agent has not changed, but its contact angle becomes larger, the hydrophobicity increases, the agglomeration of micropowder decreases, and the dispersibility increases.
