124c52205777626e95ca0048c2c63733.jpgPolyacrylamide are produced by the polymerization of acrylamide, a compound obtained by the hydration of acrylonitrile. Polyacrylamide is a water-soluble polymer and insoluble in most organic solvents, has the good flocculability, can reduce the friction resistance bettween liquid, according to the ion characteristic points can be divided into anionic, cationic and non-ionic three types

Polyacrylamide application

Anionic Polyacrylamide:

It is widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry. It is also used in oil industry to enhance oil recovery which is widely used. In addition, it can be used as paper additives and textile pulp agent.

 

Cationic Polyacrylamide:

It is very efficient in usage and has high dehydration rate. It is used for the waste water treatment in alcohol factory, monosodium glutamate factory, sugar factory, beverage factory, tanneries, dyeing and other fields. It has a better effect to be used together with inorganic coagulant in particular. It can be used as paper additives as well.

 

Non-ionic Polyacrylamide:

It is the most appropriate to use NPAM, when the sewage is acidic. It is also used as agents for the textile pulp, paper chemicals, water shutoff agent, and etc.Because of its non-ionic functional group, PH value and salts have a little influence on NPAM’s flocculation. In the neutral or alkaline conditions, the flocculation effect is not as good as APAM, but better than APAM in acidic conditions.


 

 









Polyacrylamide use method & precautions

1. It is suitable to make the concentration of 0.2% aqueous solution to use neutral water

2. For the product applies to relatively wide range of water PH value, the general dosage is of 0.1-10ppm(0.1-10mg/L)

3. Fully dissolved. Firstly, when the water is mixed up, the powder is required to be added slowly and even to prevent massive flocculation and fish-eye phenomenon that will cause pipes and pumps to be blocked

4. Generally speaking, the 200 rev/min of stirring speed is appropriate, the stirring time is no less than 60 minutes

5. Confirm the optimal dosage by test.
