Study on synthesis and flocculation property of cation-polyacrylamide

On the basis of flocculating settling experimentation on flotation waste coal in Wangfenggang coal preparation plant, influence of medical dosage and cationization (CD) of CPAM samples on coal slurry’s flocculating effect was studied, difference of flocculating effect on coal slurry among different categories of polyacrylamide was discussed. Experimental results show that when the dosage of flocculant reaches 2∼4 g/m³ flotation waste, and the CD of CPAM is 5%, flocculating effect is the best, light transmittance of supernatant liquor reaches 93%. Taking 3types of sample CPAM, PAM and PHP, which formula weight vary a little, to deal with the same concn of coal slurry, when medicine dosage is 3 g/m³, flocculating effect of CPAM is the best, light transmittance of supernatant liquor reaches 92%.
