How to Make Polyacrylamide?

Dongying Shun Tak Chemical is a a specilized chemicals manufacturer and supplier of polymer polyacrylamide, hydroxypropyl guar gum powder R & D.

Polymer flocculant (polyacrylamide) anionic, cationic and non-ionic series.

The product advantages of Shanghai Mina Qing Industry & Trade Co., Ltd:

Adding less,the effect is apparent,the price have competitive advantages,can quickly to reach the sewage treatment effects,which reduce the cost of production,and significantly increase the capability of sewage treatment.

Now let me introduct the invention of how to make the polyacrylamide which suitable for papermaking black liquor treatment.There are three steps:

(1)Adding soda ash in the 21.0-25.0% aqueous solution of acrylamide,and adjust  the temperature to 5-12 ° C.

(2)Purged with nitrogen,add in the pharmacy and initiator,after the polymerization reaction,when the temperature rises to 70-90 degrees,add in the steam for hydrolysis,after 1-4 hours of hydrolysis,it will become gelation.

(3)After Glue block caused colloidal by the granulator,then drying.Dried particles,heat stabilizers and tackifier through grinding and sieving,the final product is formed.
