What are the difficulties of crosslinking in polyacrylamide?

Difficulties POLYMER, 1990, Vol 31, August 1547 Crosslinking kinetics in polyacrylamide: H. Tobita and A. E. Hamielec mainly arise from the complicated behaviour of the pendant double bonds, namely they may react inter- molecularly and intramolecularly.

What is nonionic polyacrylamide?

Nonionic polyacrylamide is widely applied in the field of building materials as an external additive for concrete, which can improve the interaction between concrete particles and thereby the strength and toughness of concrete is increased.

What is anionic polyacrylamide?

Anionic Polyacrylamide, is solid powder water-soluble polymer with varying molecular weight and charge density. It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water and allow rapid settlement of finely suspended solids.

What is cationic polyacrylamide?

Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and can decrease the resistance between liquids.

What is sinofloc nonionic polyacrylamide?

Sinofloc nonionic polyacrylamide has good water solubility even in cold water. Moreover nonionic polyacrylamide can be greatly flocculated under a small dosage like 0.01~10ppm. And our nonionic polymer shows a great performance when joint using with inorganic flocculant like polymerized ferric sulfate, poly aluminum chloride, and iron salt.

What is a nonionic polymer flocculant?

Our nonionic polymer flocculants is amorphous, free-flowing powder, with Molecular Weight: 5 to 15 million. What Kinds of Nonionic Polyacrylamide are Available in Sinofloc? Sionfloc nonionic polyacrylamide is available in solid status. What’s the Main Application for Nonionic Flocculants?
