Anionic Polyacrylamide Blufloc A 7519 Flocculant High Molecular Weight Polymer , CAS No. 9003-05-8

Blufloc A-7519 Anionic Polyelectrolyte Medium Molecular Weight Polymer Water Treatment, Paper Mill, Sugar Mill, Oil Drilling CAS No. 9003-05-8 A-7519 Grade

Blufloc A-7519 Description:   

Appearance: white granule Molecular weight: 19 - 22 million minimum Granule: 20 - 100 mesh Solid content: 88% minimum Hydrolyzing degree: 10 - 20%, 20 - 30% or 30 - 40% Dissolving time: 2 hours maximum (10°C) Insoluble: 0.5% maximum Monomer free: 0.05% maximum Anionic Polyelectrolyte A-7519 grade (APAM) is a water soluble polymer formed from acrylamide (a compound with the molecular formula C3H5NO) subunits. It has a big range of high molecular weight from 5-25 million, with an anionic charge density ranging from 10-60%. 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.

Blufloc A-7519 Application Fields:

1. Well Drilling Mud Additives:

In oilfield, Blufloc A-7519 can worked as mud additives to increase the viscosity of water to impove the effectiveness of the water flooding 

process.

2. Industrial Wastewater Treatment:

Dosing polyacrylamide can reduce the consumption of coagulant and speed up sedimentation.

3. Textile Auxiliary Agent:

PAM can be added with some other chemicals to prepare chemical grout, is used to starch textiles, can improve

 the adhesive property, penetrability and desizing performance, enables the textile to have electrostatic prevention

 performance, reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency, 

and falling objects.

4. Paper-making:

PAM can be used as fixing agent, residency agent, filtration aid and paper dry and wet intensity reinforcing agent

in paper-making industry.

5. Mine Washing:

PAM can be used in coal washing tailing centrifugal separation, for sedimentation and filtration of coal powder 

and coal mud, and can improve the recovery rate of coal powder and the filtration speed.
