CAS 9003/5/8 Anionic Polyacrylamide Powder 10-30 Million Molecular Weight

Anionic Polyacrylamide Of Oil Displacement Additive

Strategies for Use: First let's consider the anionic acrylamide retention aids. These are often used for alkaline papermaking, though they also can be used under acidic conditions. The most basic rule is that the furnish must have a suitable "cationic source" to serve as anchoring points for the anionic retention aid. Such materials as polydimethlammonium-epichlorohydrin (polyamine), polydiallyldimethylammonium chloride (poly-DADMAC), and cationic wet-strength resins are especially effective in this role as "promoters" of the retention aid. Alum also can be used as a promoter, especially if the pH is below 6 or if the alum is added at a point where it is in contact with the furnish for a few minutes or less before the retention aid addition. The most popular addition point for a retention aid is right after the pressure screen(s), since this gives the highest retention efficiency. The papermaker has an incentive to use as little retention aid as practical - only enough to keep the paper machine from getting too dirty, to avoid basis weight fluctuations, and to avoid runnability problems. Higher levels are likely to floc the fibers enough to hurt the uniform appearance of the paper, i.e. its "formation." Another alternative is to add the retention aid before the screen(s), possibly achieving a better balance between formation uniformity and retention.Product

Application

1. Materials used for drilling mud additives, can reduce the friction of the drill bit to extend the service life of drill bits to improvethe penetration rate and the footage, reduce the time for drilling the plug, the collapse of effective anti-wells, in addition to thickening the water used in flooding, fracturing fluid and selective water

shutoff, for Enhanced Oil Recovery Significant Effect;

2. In the mining, coal mining industry can be used for waste water, coal washing waste water clarifier.

3. Used for municipal sewage sludge, municipal solid waste and industrial effluent;

4. Papermaking industry for the clarification of liquid caustic soda, fiber dispersing agent, can improve the beating, the filler retention agents, paper strengthening agent, can be used to improve the treatment rate and the

white water recovery;

5. Used in Textile, Carpet Industry, Sizing, Quick-setting Cement, Synthetic Resin Coating. Photosensitive

Polymers, Adhesives, Dispersing Agent, as well as Agricultural Soil Gel, Slurry Stabilizers, Soil Amendments;

6. Oil field water treatment to deal with the recovery of oil.
