湿润剂溶液在铁矿粉尘中湿润能力的实验研究

Experimental Research on Wet Ability of Wetting Agents to Iron Dust

采用滴重法和滴液法分别研究了三种湿润剂溶液的表面张力和对铁矿粉尘的浸润速度，比较了这三种湿润剂溶液对铁矿粉尘的湿润效果。结果表明：温度约25℃时，三种湿润剂溶液在一定的浓度下对铁矿粉尘都具有较好的湿润能力，其中0．2％～0．6％的十二烷基苯磺酸钠溶液湿润效果最佳。

Research on the surface tension and wetting velocity to iron dust of three kinds of wetting agent is done by adopt drop weight technique and dropping liquid separately, wetting effect of these three kinds of wetting agent to iron dust are compared. Result showing： when temperature is around 25℃, under a certain concentration these three kinds of wetting agent all have good wet ability to iron dust, the best wetting effect is sodium dodecyl benzene sulfonate solution when its concentration is between 0.2%-0.6%.
