Anionic polyacrylamide(HS3906901000) used for oilfield and water treatment

(1)Drilling mud additivies

 The polyacrylamide can be Used as drilling mud additives in oilfield exploration and development and geology,waterconservacy and coal exploration.i can prolong the bit’s life,raise the drilling rate and drilling footage,reduce the time of exchange drills.it has abvious effect in avoiding well collapse.it can also be used as oilfield fracturing fluid and profiling water blocking agent.

(2)EOR（enhanced oil recovery）

It can adjust the rheology of water injection,increase the viscosity of fisplacingliquid,improve the spreading efficiency of liquid displacement ,bring down the water permeability in strata and keep water and oil to flow at a constant speed.it is mainly used in tertiary recovery of oilfields.injection of each ton of PAM products can help to gather 100-150 tons extra crude oil.

（3) Industrial wastewater treatment.

 Especially for the treatment of wastewater containing suspendent particles which is coarse,high concentration and with positive charges and water’s PH value is neutral or alkaline.most effective for wastewater treatment of iron and steel plant,electroplatefactory,metallurgy and coal washing.

(4)it can be used as Papermaking additives.

(5)Drinking water treatment.

Many water plants in China come from river water,which contains large sum of sediment and mineral,veryturbid.after precipitation and filtration,it still can not meet the requirements.polyacrylamide is needed.water plants used to use inorganic polyacrylamides.but large additive amount is required which caused the increase of sludge volume,noteffective.use anionic PAM polyacrylamides,with 1/50 additive amount that of inorganic polyacrylamides,several times and even dozens of times effectiveness obtained than that of inorganic polyacrylamides.for those organic polluted river water,better effectiveness can be achieved while mixed used together with cationic PAM.

(6)Can be used for caustic soda’s clarification.used as retention aid,filteraid,reinforcing agent for wet and dry paper.

(7)Clarifying agent in sugar refining industry.

(8)Additives and adhesives in aquatic product feedstuff.

(9)can be used for construction bored pile.

4. Instruction for use

(1)It's very important to make the efficient dispersion during using, otherwise will cause agglomerate and "fish eyes", dissolving time will be longer.

(2)Low-hardness water for use; avoid adopting such tank or pool, which will influence on water quality.

(3)Improve the water temperature to accelerate the dissolving velocity, but not exceed 50.

(4)Stirring will accelerate dissolving, but tough stirring will make the dispersant chain broken and degradation. Shipshape agitator with 200 - 500 rpm is the best choice.

(5)Commonly mix the product into 0.05%--0.5%(w/w)solution as reserve.

(6)Adjust the optimum dosage of product according to application condition.

5. Product package

25 Kg paper plastic three-in-one compound woven bags, or according to users’ requirement; Its shelf life is 2 years.

6. Attention

It  is moisture absorbent, thus to protect from damp and moist for conservation. It should be stored in a dry and ventilate storehouse, and not be exposed to air and sunshine.
