What is nonionic polyacrylamide?

Nonionic polyacrylamide is a high polymer with a high molecular weight and a low ion exponent, which has the function of flocculation, dispersal, thickening, bonding, film-forming, relating, and colloidal stability. Its flocculation is hardly influenced by the PH value and the salt, and in the process of acid wastewater

What is nonionic polyacrylamide (NPAM)?

Nonionic polyacrylamide (NPAM) is a type of high molecular polymer or polyelectrolyte. Its molecular chain contains nonionic polar groups that can adsorb suspended solid particles in water and bridge them to form a large flocculate.

Can nonionic polyacrylamide be used as oilfield blocking agent?

additives, nonionic polyacrylamide can be used as the oilfield blocking agent. 8) Soil water-absorbent agent: nonionic polyacrylamide Can be used as the water-absorbent agent for soil water conservation and sand stabilization, seeding grass, and planting trees on slopes and sand dustproof.

How to use non ionic polyacrylamide lignocellulose?

methylene acrylamide, nonionic polyacrylamide can be used as chemical grouting agents for the water blocking of the dams, the foundations’ tunnels, and so on. 7) Oilfield blocking agent: To be used together with the lignocellulose by adding certain chemical additives, nonionic polyacrylamide can be used as the oilfield blocking agent.

How to use non ionic polyacrylamide as a grouting agent?

6) Chemical grouting agent: Mixed the dissolved 95% non-ionic polyacrylamide together with 5% NN-A methylene acrylamide, nonionic polyacrylamide can be used as chemical grouting agents for the water blocking of the dams, the foundations’ tunnels, and so on.
