Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can adsorb solid particles suspended in water to bridge between particles or condense particles to form large flocs through charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of speeding up the solution clarification and promoting filtration. Mainly used...
