Introduction of Polyacrylamide flocculant

Chinese alias: flocculating agent 3;Anionic Polyacrylamide flocculant.Polyacrylamide flocculant powder (anionic);Polyacrylamide flocculant gelⅠtype;Polyacrylamide flocculant gel Ⅱ type;Hydrolyzed Polyacrylamide flocculant;

Polyacrylamide flocculant (PAM) is a kind of linear organic high polymer, is also a kind of high polymer flocculant in water treatment products, can absorb the suspended particles in the water, link bridge role between the particles, the fine grain to form bigger floccules, and increasing the speed of the precipitation.This process is called flocculation, because good flocculation effect of PAM as flocculating agent of water treatment and is widely used in wastewater treatment.


Polyacrylamide flocculant features

1, PAM can make suspended material through electric neutralization, adsorption, flocculation effect.

2, Can pass the mechanical, physical, chemical, bonding effect.

3, PAM can effectively reduce the friction resistance of fluid, the water add trace PAM would drag reduction of 50-80%.

4, PAM under the condition of neutral and acid are thickening effect, when the PH value in more than 10 PAM easy to hydrolysis.Half the reticular structure, thickening will be more obvious.

Polyacrylamide flocculant purposes

1, Oil displacement agent, oil field tertiary oil recovery: Can adjust the rheological properties of injected water, increase the driving liquid viscosity, improving water flooding and efficiency, reduce the formation water phase permeability, oil and water can flow uniform advance.Its role is in oil production is mainly used in oil field tertiary oil recovery, every tons of polymer injected Polyacrylamide flocculant products, can be more than in 100-150 tons of crude.

2, Drilling mud materials: In oilfield exploration and development as well as water conservancy coal geological exploration, additives used as drilling mud materials, can reduce the service life of bit and improving drilling rate and penetration, reduce the congestion in the drill, hole sloughing prevention effect is obvious.Also can be used for fracturing fluid of oil field and the profile control water plugging plugging agent.

3, Industrial wastewater treatment: Especially for the high degree of suspended particles, coarser, agriculture, particles with positive charge, the PH of the water to neutral or alkaline wastewater, steel mill wastewater, electroplating factory wastewater, metallurgical waste water, coal washing waste water and sewage treatment, the best effect.

4, Water treatment: Many waterworks water from rivers in China, sediment and mineral content is high, more cloudy, even after lake filtering, still cannot meet the requirements, need dosing flocculants.The waterworks using inorganic flocculants, but adding the quantity is big, caused the sludge quantity increases the result is bad.Using anionic Polyacrylamide flocculant flocculant, dosing quantity is 1/50 of the inorganic flocculating, but the effect is several times of inorganic flocculants, even dozens of times.For polluted river water and organic matter used cation polypropylene amine effect is better.

5, Papermaking additives:Pulp and paper industry can be used for clarification of caustic soda, retention agent, filter aid, paper wet strength enhancer.

6, Used as sugar juice clarifying agent in sugar industry:Used as additive of aquatic beverages and adhesives.

Use method and matters needing attention

1, With a concentration of 0.2% aqueous solution to use neutral salt-free water is advisable.

2, Because the water PH value scope for this product more extensive, general additive amount of 0.1 to 10 PPM (0.1-10 mg/l).

3, Fully dissolved.Asked dissolved water, fully mixing up again after a slow, even add powder, prevent a chunk of floccules and fisheye phenomenon caused by the blocking of pipeline and pump.

4, The mixing speed is 200 RPM commonly advisable, time not less than 60 minutes, raise the temperature of 20-30 degrees Celsius, can accelerate the dissolve.The highest temperature liquid should be less than 60 degrees.

5, To determine the best dose.Through the experiment the optimum dosage before use.Because of low dosage, doesn’t work, the dosage is too high, but counterproductive, more than a certain concentration, PAM instead of flocculation, instead of using dispersion stability.

6, This product should be stored in a cool, dry place, prevent to be affected with damp be affected with damp.

7, Workplaces, often should wash with water, keep clean.Because of its low degree is big, scattering of PAM in underground water surface is smooth, prevent operators slip cause safety accidents.

8, This product with inner plastic bags, outer with plastic film bag, each bag is 25 kg.
