Polyacrylamide (PHPA) Powder
1. Product Description
It is the white powder or white granular powder. The APAM has good water solubility, and it can be dissolved in water by arbitrary proportion but not in organic solvents. It has the characteristics of high-polymer electrolyte in the neutral and alkaline medium, and it is sensitive to the electrolyte salt. And it can be cross-linked into insoluble gel with the high valence metal ions.

3. Applications
Oil-displacing agent of oil field tertiary oil recovery:It can adjust the rheology of filled water, increase the viscosity of driving liquid, improve water drive wave and efficiency, lower water phase permeability in ground layer, and enable water and oil to flow forward at even speed. Its effect is that it is mainly used in tertiary oil recovery of oil fields in the aspect oil production, and raw oil of about 100 to 150ton more can be produced through filling the macromolecule polymer product one ton.
Well drilling mud raw materials:in oil field exploration and development and exploration of geology, water and coal, it is used as adhesive of well drilling mud raw materials, can improve the service life of drill bits, improve the drill speed and drilling footage, and reduce plug in replacing drill, and has prominent well slough preventing effect, and it can be used as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.
Industrial Waste Water Treatment:It has the best effect in particular in processing sewage water with suspended particulate, thicker size, high concentration, positive charge particle, neutral or alkalescence water PH value, waste water of iron and steel plants, waste water of electroplating factory, metallurgy waste water, coal washing waste water and other waste water.
Drinking Water Treatment: Water sources of many tap water factories in China come from rivers, the sand and mineral contents are higher, water is muddy, the water still can not achieve demands although passing through sedimentation and filtration, and flocculating agent needs adding; however huge adding amount generates increased mud amount and bad effect. The adding amount is only 1/50 of inorganic flocculating agent if anionic-polymer is adopted as flocculating agent, but the effect is several times better than the organic flocculating agent, and even dozens of times. If the river water with severe organic matter pollution can be matched with anionic-polymer for use, the effect will be better.
Paper-making adhesive: The product can be used as fining agent, residency agent, filtration aid and paper dry and wet intensity reinforcing agent in paper-making industry.
