| 摘 要： | 煤水浆是一种具有触变性的固液两相悬浮体,鉴于过去对触变性仅能进行一般的定性研究,本文介绍了一种简便易行而且准确可靠的定量试验研究方法,分析了利用这种试验方法所得出的大量试验结果,并讨论了对煤水浆触变性有着明显影响的三种因素(剪切速率、煤水浆浓度和温度)及其具体影响规律。

| Abstract: | Coal-Water Slurry is a kind of solid-liquid suspensions, which has the characteristics of thixotropy.In this paper,the breaking up and the recovering of the structure of CWS is studied first.Then, a easy and simple, but accurate and reliable quantitative method of experiment is introduced to describe the thixotropy of CWS.Studies of thixotropic characteristics of CWS will be in progress from two fields.One is the study of the process of thixotropy, the other is the study of results of thixotropy. In this paper, coefficient A(named structure breaking-up coefficieut ) related to time is used to describe the process of thixotropy of CWS; another quantity AT ( named absolute quantity of thixot- ropy) is used to describe the results of thixotropy of CWS. Three factors --shear rate, concentration and temperature of CWS which affect the thixotropy of CWS mainly--are studied. It is discovered that the increase in concentration and shear rate, and the decrease in temperature cause the increase of thixotropy of CWS while the process of thixotropy will be prolonged. |
