用于煤浮选表面活性剂的选取

Selection of surfactant in coal floatation

为研究表面活性剂对煤浮选的促进作用 ,选取多种表面活性剂进行实验 ,优选出 6种表面活性剂。这几种表面活性剂对煤浮选有良好的促进作用 ,具有捕收能力强、选择性高、节油明显等优点 。

In order to study the behavior of surfactant in coal floatation,the author selects different surfctants to choose six surfactants.The tests show that the surfactants have good behaviour in floatation,and have advantages,such as good collective power,high selectivity and saving oil ,so they have good prospect.
