| 摘 要： | 介绍了在煤质、煤粒度、水煤浆浓度及添加剂等条件基本相同条件下，水煤浆体系pH值对其静态稳定性的影响。适当提高体系pH值可在一定程度上改善煤浆的静态稳定性。用淮南望峰岗选煤厂精选煤，东宠煤及兴隆庄煤制的水煤浆体系实验所得结果完全相同。讨论该条件下pH值影响水煤浆静态性的可能原因。

| Abstract: | Effect of pH value on the static stability of coal water slurry at the same conditions such as coal quality, coal size distribution, CWS concentration and additive is introduced. The static stability of CWS can be improved when increasing the pH value in system at a suitable condition. The experiment results are same when the CWS preparation by using clean coal of Huainan Wangfenggang coal preparation plant, Dongpang coal and Xinglongzhuang coal. The probable cause of the pH value effect on the static stability of CWS at these condition is also discussed. |
