摘  要:
研究了甲壳胺作为絮凝剂对褐藻胶胶液的絮凝作用及漂浮效果。结果表明,甲壳胶对褐藻胶胶液具有较强的絮凝作用,其中,10ppm甲壳胺用量的漂浮效果较好,可大大缩短漂浮时间,对清胶液的透光率、粘度和胶收率均有不同程度的提高。在褐藻胶实际生产中,用甲壳胺作絮凝剂(10ppm),可将间歇漂浮工艺时间从4h缩短至1.5h;并可实现漂浮工艺连续化,同时提高了胶收率。

摘  要:
The floating effects of chitosan used as a flocculant on algin suspension were studied. Chitosan at low concentrations, especially at 10ppm (w/v), appeared to have a strong flocculation effect on algin suspension. It was found that the use of chitosan in floating experiments induced the improving of floating effects, reducing floating time, and enhancing the viscosity and transmittancy of the algin fluid. In the practical production, the time of intermittent floatation procedure was reduced from 4h to 1.5h by using 10ppm (w/v) chitosan in algin suspension of the floatation process. Consecutive floatation process was achieved in 1arge-scale algin production with good floating effects and high yields of algin.
