煤用微乳液助滤剂的研制

PREPARATION OF MICROEMULSION FILTER AIDS OF FINE CLEAN COAL

以表面活性剂SLL(自制乳化剂)及SLL和Span85复配物为乳化剂,醇为助乳化剂,煤油为分散介质,研究了制备丙烯酰胺反相微乳液的条件,并在水溶性引发剂的引发下进行了微乳液聚合.用聚合后的体系对6种不同变质程度的煤进行了煤泥真空过滤脱水实验,实验结果表明,经聚合得到的复合体对六种煤泥都具有很好的助滤脱水效果.

An inverse microemulsion system of acrylamide, using SLL or the complexes SLL and Span85 as emulsifiers ,alcohol as a cosurfactant and kerosene oil as a dispersive medium was investigated. The microemulsion polymerization of acrylamide initiated by potassium persul- fate. At the same time, it carried out filtration test of six fine clean coals using the systems after polymerization. The results showed that it represented better filtration effect.
