二氧化硅悬浮体的絮凝

摘要

The flocculation of two kinds of silica particles with different surface properties have been studied on the addition of PAM.In certain pH range, PAM can flocculate suspensions of SiO2particles which have been calcined with a little water added. Although PAm doesn’s flocculate suspensions of SiO2 particles calcined with no water added, it produces good coordinate flocculating effect on mixing with PA.
