| 摘 要： | 采用水溶液共聚法,以十八烷基二甲基烯丙基氯化铵为疏水单体,以过硫酸铵与亚硫酸氢钠为引发剂,制备了疏水改性型聚丙烯酰胺HPAM,并对其在煤泥中的絮凝浮选效果进行了选择性絮凝-浮选试验及浮选速度试验．研究结果表明：与常规的阴离子聚丙烯酰胺APAM相比,HPAM为絮凝剂时精煤产品的产率、浮选完善指标与分选选择性评价指标更高,对微细粒煤泥能够取得更优的浮选效果。

| Abstract: | Hydrophobically modified polyacrylamide HPAM was prepared by water solution copolymerization, using eighteen alkyl two methyl allyl ammonium chloride as hydrophobic monomer, ammonium persulfate and Sodium Bisulfite as initiator, and selective flocculation flotation test and flotation speed test of flocculation and flotation effect in coal slurry were carried out. The results showed that compared with conventional anionic polyacrylamide APAM phase Compared with HPAM as flocculant, the productivity, flotation improvement index and selectivity evaluation index of clean coal are higher, and the flotation effect of fine coal slime is better. |

| Keywords: | Hydrophobic modified polyacrylamide Slime Selective flocculation-flotation Flotation speed test |
