Anionic polyacrylamide (Praestol A 3040 L Praestol A 3075 L) can be replaced by ASIAFLOC A1012 and A3016

Praestol A 3075 L is two anionic polyacrylamides with different degree of hydrolysis and molecular weight. Praestol A 3075 L is mainly used in mineral processing and water treatment. The ASIAFLOC A1012 and ASIAFLOC A3016 can be completely replaced and have good application effect.

Product Overview:

Anionic polyacrylamide (APAM) is a water-soluble linear polymer synthesized by high degree of polymerization. Supplied in a fine granular state or colloidal form free of dust and flakes, completely soluble in water and rapidly soluble due to its micropellet form. Different types of polyacrylamide have different active groups, can make different suspended particles flocculation, easy to filter, separation. Polyacrylamide is almost insoluble in any organic solvent and is largely soluble in water. It is widely used in many industries, such as flocculation, thickening, bonding, scale inhibition, colloid stabilization, resistance reduction, film formation, gel and biological materials. Our anionic polyacrylamide PAM appearance are white dry powder or particles, effective PH range of 7-14, according to different uses is divided into two production processes, a homopolymer (non-ionic polyacrylamide pre-hydrolysis), a copolymer (acrylamide and acrylic acid or sodium acrylic acid).

Main uses:

1, industrial wastewater treatment: for suspended particles, coarse, high concentration, particles with positive charge, PH value of water neutral or alkaline sewage, steel mill wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, the effect is good.

2, sand washing sewage treatment: treatment mechanism sand sewage, cobblestone, mountain sand, river sand, mountain material, wind fossil and other raw materials sand sewage treatment, belt filter press and plate and frame filter mud dry drainage.

3, starch factory and distillery loss of starch wine tank recovery: now many starch factory wastewater contains a lot of starch. Anionic polyacrylamide is now added to make starch particles flocculate precipitation, and then the sediment by pressure filtration into cake, can be used as feed. Cationic dehydration and press filtration can also be used in distilleries.

4. Treatment of coal washing wastewater.

5, paper additives: anionic polyacrylamide (PAM) in the paper industry to burn alkali clarification, fiber dispersant, can improve the beating degree, filler retention agent, paper strengthening agent, can be used to improve water filtration rate and water recovery. Adding trace PAM-03 anionic polyacrylamide into the pump-port pulp-storage tank before paper making can increase the retention of water fillers and fine fibers on the net by 20-30%. Each ton can save pulp 20-30kg.

6, oil field three recovery oil displacement agent: anionic polyacrylamide can adjust the rheological properties of injected water, increase the viscosity of driving liquid, improve water flooding sweep efficiency, reduce the permeability of water phase in the formation, so that water and oil can flow forward uniformly. Its role in oil exploitation is mainly used for three oil recovery in the oil field, each injection of a ton of polymer polyacrylamide products, can be more than 100-150 tons of crude oil

7, drilling mud material: in the oil field exploration and development and geology, water conservancy, coal exploration, anionic polyacrylamide used as drilling mud material additives, can increase the service life of drill bit, improve drilling speed and footage, reduce the blockage of drilling, anti well collapse effect is obvious. Fracturing fluid of polyacrylamide oil field and water plugging agent for profile control and water plugging.
