以粉煤灰、煤矸石、电石渣、镁渣和赤泥等五种工业固体废弃物为原料，按照不同酸度系数进行复配，分别采用灰熔融温度测定仪和高温黏度测定仪测定了高温下复配样品的熔融特征温度和黏度变化。结果发现，酸度系数在0.95~1.19范围内时，熔融特征温度随酸度系数的增大而升高；在酸度系数较大时，酸度系数对熔融温度的影响更为明显；熔体的黏度随温度降低而增加；当黏度在0~1000 mPa·s范围内，随样品中Fe2 O3含量增加，熔体黏度随温度的变化速度降低。
Five samples of industrial solid waste were formulated by the different acidity coefficient. The characteristic temperature was tested by ash fusion point determination meter, and the high-temperature viscosity was detected by high-temperature viscosity tester. The result show that the melting temperature increases with the increase of the acidity coefficient during the range of acidity coefficient of 0 . 95-1 . 19 , especially for the sample with higher acidity coefficient. The viscosity of the high-temperature melt always increase with the temperature decreases, when the viscosity increased from 0 mPa·s to 1000 mPa·s, the rate of the viscosity changed with temperature, which seems relate to the content of Fe2 O3 in the test sample, but lack of correlation with the acidity coefficient. As a whole, the rate of the viscosity changed with temperature decrease with the content of Fe2 O3 increases.
