化学湿润剂的湿润能力试验

Test on the Wetting Behaviour of Chemical Wetting Agents

用氯化钙、水玻璃、丁二酸钠、十二烷基磺酸钠和十二烷基苯磺酸钠等5种化学湿润剂对4种现场采集的粉尘进行正向渗透试验,结果表明:这些化学湿润剂均能改善水湿润粉尘的能力。

Based on a special downward penetration test device, a great number of experiments have been done to study the wetting behaviour of calcium chloride, water glass, sodium succinate, sodium dodecyl sulfonate and sodium salt solution of dodecyl benzene sulfonic acid in four dust samples, and the surface tension of the solution was also measured. The result showed that the five wetting agents could improve the wetting ability of water to dust in great extent.
