Anionic Polyacrylamide Emulsion Medium Molecular Weight Polymer , CAS No. 9003-05-8

EA-6518 Grade

Description:   

Anionic polyacrylamide Emulsion EA-6518 grade (APAM) is a water based polymer. Anionic Polyacrylamide has a big range of high molecular weight from 16-25 million, with an anionic charge density ranging from 10-60%. EA-6518 grade has high molecular weight, and medium charge degree. It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water. Due to the polar groups on the molecular chain containing a certain amount, it can through the adsorption of solid particles suspended in water, bridging between particles or through the charge and make the particle formation of large flocs condensation. So, it can accelerate the settlement of particles in suspension, have obvious to speed up the solution to clarify, promote filtering and other effects. Mainly used for various industrial wastewater flocculation sedimentation, sedimentation and clarification treatment, such as iron and steel plant wastewater, electroplating wastewater, wastewater metallurgy, coal washing wastewater treatment, sludge dewatering. Can also be used to clarify and drinking water purification treatment, and sugar & juice mills. Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun. It is slightly acidic, when skin contact, wash immediately with plenty of water.
