Polyacrylamide can be divided into cationic polyacrylamide and anionic polyacrylamide and nonionic polyacrylamide and amphoteric polyacrylamide according to different degree of ion and hydrolysis degree and different applications.
Applications of polyacrylamide
Anionic polyacrylamide can be Used as drilling mud additives in oilfield exploration and development and geology,water conservacy and coal exploration.
It 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.
Polymersco recommend our models of Polymersco A3019 and Polymersco A3018.
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, electroplate factory, metallurgy and coal washing.
We recommend our models of Polymersco A2718 and Polymersco A3018 and Polymersco A2015
PHPA polyacrylamide can adjust the rheology of water injection, increase the viscosity of fisplacing liquid, 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.we recommend our models of Polymersco A2320 and Polymersco A3020 and Polymersco A2525
Many water plants in China come from river water, which contains large sum of sediment and mineral,very turbid.
After precipitation and filtration,it still can not meet the requirements.
Flocculant is needed.water plants used to use inorganic flocculants.but large additive amount is required which caused the increase of sludge volume,not effective.use anionic polyacrylamide flocculants,with 1/50 additive amount that of inorganic flocculants,several times and even dozens of times effectiveness obtained than that of inorganic flocculants.
For those organic polluted river water,better effectiveness can be achieved while mixed used together with cationic polyacrylamide.we recommend our models of Polymersco A2517 and Polymersco A3517 and Polymersco A2520.
