USAGE
Polyacrylamide is a kind of water-soluble linear polymer, supplied as free-flowing particles status without dust or colloid, perfectly soluble in water. The product can be dissolved fast for its particle form. Different polyacrylamides have different active groups, which flocculate different suspended particles for filtration and separation. The product is easily dissolved in water, insoluble in any organic solvent. In many industries, this product is used for flocculation, thickening, cementation, anti-scaling, colloidal stabilization, drag reduction, film formation, gelling, biological materials and so on.
Applications details can be described as below:
(1) As a flocculating agent, mainly used in industrial solid-liquid separation process, including settlement, to clarify, concentrate and sludge dewatering processes. Applications for all the major sectors are: Urban Sewage Treatment, Paper, Food Processing, Petrochemical, metallurgical Processing, Dyeing and the Sugar and all kinds of industrial wastewater treatment.
(2) In the paper industry can be used as dry strength agents, retention agent, filter aid. They can be greatly improved as paper quality, enhance the physical strength of paper and reduce the loss of fiber, can also be used in the treatment of white water at the same time, in the deinking process can play a significant flocculation.
(3)In the mining, coal mining industry can be used for waste water, coal washing waste water clarifier.
(4)They Can be used for dyeing wastewater, leather wastewater, oily wastewater treatment, so that turbidity removal, decolorization, to achieve the emission standards.
(5)For the tap water in the river water treatment plant flocculant


ADVANTAGE
- Excellent water retention even at low concentration.
- Excellent thickening effect.
- Good resistance to salt and temperature change.
- Imparts excellent rheological property.
