通过往反渗透膜处理水中加入一定量分散剂制备出分散稳定性能好的碳化钛水基溶液,并采用沉降稳定性分析、XRD分析、红外光谱分析和透射电镜观察来分析其状态。沉降稳定性分析探讨了分散剂用量对溶液沉降稳定性的影响,XRD结果表明水基溶液中的碳化钛晶相成分未发生变化,红外图谱结果表明分散剂在碳化钛表面形成了化学吸附,透射电镜观察到溶液中的纳米碳化钛基本上是以单个粒子形式存在。
By adding a certain amount of dispersant into the water of reverse osmosis membrane, a water-based titanium carbide aqueous solution with good dispersion stability was prepared and analyzed by sedimentation stability analysis, XRD analysis, infrared spectrum analysis and transmission electron microscope observation. Sedimentation Stability Analysis The influence of dispersant dosage on settling stability of the solution was discussed. XRD results showed that the crystal phase composition of the solution did not change. The infrared spectrum showed that the dispersant formed chemical adsorption and transmission on the surface of titanium carbide Electron microscopy showed that the solution of nano-titanium carbide is basically a single particle form.
