【摘要】：通過研究高分子表面活性劑復(fù)配制成泡沫型降塵劑來降低井下煤塵濃度,減少煤礦粉塵傷害。試驗以玉米淀粉為原料和十八醇接枝共聚生成表面活性劑,以正交實驗確定最佳條件為氧化淀粉∶十八醇=1∶1.5、溫度70℃、時間8h、溶劑用量55m L,其與十二烷基硫酸鈉和十四烷基三甲基溴化銨表面活性劑相比較,潤濕性和潤濕速率都較佳。以此表面活性劑為主劑,復(fù)配以起泡劑和絮凝劑,檢測不同配方對煤塵潤濕性、凝聚性和保水性的影響,確定出泡沫抑塵劑的最佳復(fù)配比例為表面活性劑∶聚丙烯酰胺∶仲辛醇=7∶1∶2。該泡沫抑塵劑制備工藝流程簡單,原料價格低廉,且能夠很好的潤濕煤塵,提高降塵效率。
[Abstract]:In order to reduce the concentration of coal dust and reduce the damage of coal dust in coal mine, the foaming dust reducer was prepared by using polymer surfactants. Corn starch was used as raw material and octadecanol was grafted to form surfactant. The optimum conditions were determined by orthogonal experiment: octadecanol 1: 1.5, temperature 70 鈩，
