Polyacrylamide(PAM) is water-soluble linear polymer with high degree of polymerization. It is soluble in water, insoluble in most organic solvents such as methanol, ethanol, acetone, ether, aliphatic hydrocarbons and aromatic hydrocarbons It is widely used in metallurgy, beneficiation, oil extraction, coal washing, chemical industry, papermaking, textile, environmental protection, building materials, sugar manufacturing, medicine, agricultural production and other departments. Generally typical polyacrylamide are cationic polyacrylamide(CPAM), anionic polyacrylamide(APAM), non-ionic polyacrylamide(NPAM), amphoteric polyacrylamide.


Cationic Polyacrylamide

Cationic Polyacrylamide is a copolymer of cationic monomer and acrylamide. It is a water-soluble linear high molecular organic polymer.

Specification

Appearance	Molecular Weight	Ion degrees	Solid Content	Insoluble matter in water	Dissolution Time	Residual Monomer	Configuration concentration
White granule/powder/emulsion	3000,000-12,000,000	5%-55%	≥90%	≤0.02%	≤60 min	≤0.1%	0.1%-0.5%

Characteristic

1.  Good water solubility, can be completely dissolved in cold water.
2.  High polymer electrolyte, suitable for anion-charged and organic-rich wastewater treatment.
3.  Cationic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, iron salts, etc.) have significant effects when used together.
4.  Cationic polyacrylamide has the following functions: clarification and purification; Enhanced sedimentation and filtration; thickening and other functions.

Application

1.  As a flocculant, it is mainly used in industrial solid-liquid separation processes, including sedimentation, clarification, concentration, and sludge dewatering processes. The applied industries are: urban sewage treatment, papermaking industry, food processing industry, petrochemical industry, metallurgical industry, beneficiation industry, dyeing industry and sugar industry, and wastewater treatment of other industries. It  is also used in sludge sedimentation and sludge dewatering in the treatment of municipal sewage and meat, poultry, and food processing wastewater.
2.  In the paper industry, it can be used as a paper dry strength agent, retention aid, and filter aid, which can greatly improve the quality of paper, save costs, and increase production capacity.
3.  Cationic polyacrylamide can be used as a clarifier for mining wastewater and coal washing wastewater in the mining and coal preparation industries.
4.  Cationic polyacrylamide can be used for the treatment of dyeing wastewater, leather wastewater and oily wastewater to remove turbidity and decolorization to meet discharge standards.
5.  Cationic polyacrylamide used as flocculant for water treatment in waterworks from river sources.
6.  It is also widely used as oilfield chemical agents in oilfield operations: such as clay anti-swelling agents, thickeners for oilfield acidification.

Anionic Polyacrylamide

Anionic polyacrylamide products are water-soluble polymers, easily soluble in water, insoluble in general organic solvents such as benzene, ether, lipids, and acetone.

Specification

Appearance	Molecular Weight	Degree of hydrolysis	Solid Content	Insoluble matter in water	Dissolution Time	Residual Monomer	Configuration concentration
White granule/powder/emulsion	3000,000-25,000,000	10%-35%	≥90%	≤0.02%	≤60 min	≤0.1%	0.1%-0.5%

Application

1.  Industrial wastewater treatment: Especially for suspended particles, thick, higher concentration, positively charged particles, neutral or alkaline wastewater, steel plant wastewater, electroplating wastewater, metallurgical wastewater, coal washing wastewater, etc.
2.  Drinking water treatment: Using anionic polyacrylamide as flocculant, the dosage is 1/50 of inorganic flocculant, but the effect is indeed many times or even dozens of times. It works better with cationic polyacrylamide for rivers with serious organic pollution.
3.  Paper additives: It can be used as clarification of caustic soda, retention aid, filter aid, enhancer for wet and dry strength of paper in paper industry.  
4.  Used as sugar clarifier in sugar industry.
5.  Used in making incense, coatings and other fields as thickener or binder.
6.  Used as additives and binders in aquatic feed.

Non-ionic polyacrylamide

Non-ionic polyacrylamide is made from homopolymerization of acrylamide, Is a high molecular weight low ion linear polymer.

Appearance	Molecular Weight	Degree of hydrolysis	Solid Content	Insoluble matter in water	Dissolution Time	Residual Monomer	Configuration concentration
White granule/powder/emulsion	3000,000-15,000,000	≤5%	≥90%	≤0.02%	≤60 min	≤0.1%	0.1%-0.5%

Application

1.  Coal washing: Used for centrifugal separation of coal washing tailings and used in the precipitation and filtration of coal powder and slime, which can improve the recovery rate of coal powder and the filtration rate.
2.  Textile auxiliaries: Add some other chemicals to make a chemical slurry, which can be used for textile sizing to improve adhesion, permeability and desizing performance.
3.  Sewage treatment: When the sewage is acidic, non-ionic polyacrylamide is more suitable, combination with inorganic flocculant polyaluminum chloride and aluminum sulfate, the effect is better in water treatment.
4.  Metallurgical beneficiation: Leaching solution and residue can be added to PAM to improve sharing efficiency in flotation and smelting of Zinc, Manganese and Copper Ore.
5.  Sand control: Dissolve non-ionic polyacrylamide to 0.3% concentration and add cross-linking agent, Spray on the desert to control the sand.
6.  Chemical grout: 95% PAM and 5% Bis-acrylamide miscible can be used as chemical grout in dam,foundation, tunnel, etc.
7.  Soil humectant: Moisturizing and fixing sand in soil, used as a moisturizer on hillsides for planting grass, planting trees, and fixing sand and dust.
