用聚丙烯酰胺通过正交试验法改性合成了含有氧肟酸基团的水溶性高分子;将改性产品和工厂提供的絮凝剂用于赤泥沉降,发现改性产品具有上清液浓度小、絮团结实、底流固液比高的优势.
Through cross test, soluble polymer with hydroxamic acid was synthesized from polyacrylamide(PAM) by modification. Comparing better synthetical product with flocculents provided by factory, the advantages of synthetical product,such as lower turbidity of topliquid,more stable floccule and higher ratio of solid and liquid were found in sedimentation of red mud.
