Preparation of Polymer Suppressant in Coal Transportation under Single Mode Microwave Irradiation

Abstract:

The aqueous solution polymerization of acrylic acid, acrylamide and oxidized starch under single mode microwave irradiation was studied, and a polymer suppressant was synthesized. The factors that influence on performance of the polymer suppressant were discussed, including microwave irradiation time, neutralization degree of acrylic acid (AA), the dosage of oxidized starch. The polymer suppressant was characterized by IR and scanning electron microscopy (SEM). Results indicated that the optimal synthetic conditions are as follows: microwave irradiation power, 300 W; radiation time, 2 mins; 50% neutralization degree of the AA; m(AA) : m(AM) : m(oxidized starch)= 5.0 : 3.3 : 3.4, weight ratio initiator in the feed is 0.4%, respectively.
