Theta高温黏度仪测定煤灰黏度的方法

煤灰黏度是煤质分析中的一项重要指标,主要用于动力用煤和气化用煤,根据煤灰黏度的大小,来确定煤样是否适合液态排渣炉的使用,本文研究使用Theta高温黏度仪测定煤灰黏度的方法,该方法样品用量少,操作简单,温度梯度窄,数据全面,通过美国NIST标准材料测试协会717a玻璃对高温黏度计进行较正,该方法重现性好,准确度高。

水煤浆飞灰扫描电镜和静电除尘特性分析

Study on Preparation of Ceramic Material and Its Properties

This paper introduces the classification, properties and application of porous ceramic materials, reviewed preparation of porous ceramics. Taking fly ash and red mud as the main raw material to generate porous ceramics, the paper study the influence of different proportions of raw materials, sintering temperature, porosity of porous ceramic sample rate, bending strength, and microstructure. The results show that, fly ash and red mud proportioning and sintering temperature are the main factors that influence the structure and properties of samples. The4#sample is a kind of high porosity and high strength quality of porous ceramics.
