对高铝粉煤灰生产氧化铝联产硅钙渣进行物性分析的基础上,研究了过滤压力及颗粒粒径对滤饼含水率的影响.分析了季铵盐类表面活性剂FL02对硅钙渣滤饼含水率的影响并用红外光谱进行表征,分析作用机理.结果表明,硅钙渣为中等可压缩性物料;过滤压力取0.3 MPa时,硅钙渣滤饼含水率由49.73％降到44.56％;颗粒粒径为0.075～0.125 mm时,硅钙渣滤饼含水率最低为41％;加入季铵盐类表面活性剂FL02使滤饼含水率降低,最适宜添加量为0.75％(相对干固相的质量分数),硅钙渣滤饼含水率从44.71％降到39％,由红外光谱看出季铵盐类表面活性剂FL02的亲水基与硅钙渣表面羟基键合形成氢键,致使表面自由羟基数量减少.
