Abstract

The effect that mechanical treatment of SKS-30 ARK latex by mixing in a gap between coaxial cylinders exerts on the latex resistance to an electrolyte and on the polymer yield in coagulation with two types of coagulants, sodium chloride and N,N-dimethylaminopropyl carboxy betaines derived from vegetable oil fatty acids, was studied. Such treatment decreases the rapid coagulation threshold and increases the coagulum yield. The effect is caused by partial breakdown of hydrate shells of particles as a result of mechanical action in a shear stress field.
