Product Details
(PAM) Polyacrylamide is a general term for polymers that are homopolymers of acrylamide or copolymerized with other monomers. (PAM) Polyacrylamide is one of the most widely used varieties of water-soluble polymers. Polyacrylamide (PAM) is widely used in industries such as oil extraction, papermaking, water treatment, textiles, pharmaceuticals, and agriculture. According to statistics, 37% of the total global production of polyacrylamide (PAM) is used for wastewater treatment, 27% for the petroleum industry, and 18% for the paper industry.
Product Introduction
Polyacrylamides (PAM), abbreviated as PAM, are a type of linear polymer that is widely used in water-soluble polymer compounds. Polyacrylamide and its derivatives can be used as effective flocculants, thickeners, paper enhancers, and drag reducing agents for liquids. They are widely used in water treatment, papermaking, petroleum, coal, mining, geology, light textile, construction, and other departments.

Product classification
1. According to appearance, it can be divided into colloidal (PAM) polyacrylamide and granular (PAM) polyacrylamide
2. It can be divided into cationic (CPAM) polyacrylamide, anionic (APAM) polyacrylamide, non-ionic (NPAM) polyacrylamide and Zwitterion (ACPAM) polyacrylamide according to the degree of ion
purpose
Widely used in water treatment, papermaking, petroleum, coal, mining, geology, light textile, construction and other departments.
Usage of cationic polyacrylamide (CPAM): Used as a flocculant in wastewater treatment in industries such as mining, metallurgy, textile, and papermaking. Used in various operations in the petroleum industry.
Anionic (APAM) Polyacrylamide Usage: Application of anionic polyacrylamide: It plays a flocculation and sedimentation role in industrial wastewater (electroplating plant wastewater, metallurgical wastewater, steel plant wastewater, coal washing wastewater, etc.).
Non ionic (NPAM) polyacrylic acid uses: clarification Catharsis, sedimentation promotion, thickening and other functions, filtration promotion. In terms of waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, papermaking, etc., it can fully meet the requirements of various fields. The use of non-ionic polyacrylamide and inorganic flocculants (polymerized Iron(III) sulfate, Aluminium chlorohydrate, ferric salt, etc.) at the same time can show greater effect.
Zwitterion ion (ACPAM) polyacrylamide uses: 1. Profile control and water shutoff agent. After oil field tests, the performance of this new Zwitterion profile control and water shutoff agent is higher than that of other single ion polyacrylamide agents. 2. In many situations, the combination of anionic polyacrylamide and cationic polypropylene produces a significant and synergistic effect when treating sewage and water supply, compared to using one type of ionic polyacrylamide alone. Improper use of both can result in white sediment and loss of effectiveness. So using composite ion polyacrylamide has a better effect.
Characteristics precautions
1. Flocculation; PAM can neutralize suspended substances through electricity, adsorb them on the bridge, and perform flocculation.
2. Adhesion: Capable of adhering and acting through mechanical, physical, and chemical processes.
3. Resistance reduction: PAM can effectively reduce the frictional resistance of fluids, and adding trace amounts of PAM to water can reduce resistance by 50-80%.
4. Thickening effect: PAM has a thickening effect under both neutral and acidic conditions. When the pH value is greater than 10, PAM is prone to hydrolysis and exhibits a semi network structure, making thickening more pronounced.
Introduction to the working principle of PAM:
1. Flocculation principle: When PAM is used for flocculation, it is related to the surface properties of the flocculated substances, especially the dynamic potential, viscosity, turbidity and the PH value of the suspension. The dynamic potential on the particle surface is the reason for particle polymerization inhibition. Adding PAM with opposite Surface charge can reduce the dynamic potential and coagulate.
2. Adsorption bridging: PAM molecular chains are fixed on different particle surfaces, forming polymer bridges between each particle, causing the particles to form aggregates and settle.
3. Surface adsorption: Various adsorption of polar group particles on PAM molecules.
Enhancement effect: PAM molecular chains and dispersed phases are linked together through various mechanical, physical, and chemical reactions to form a network, thereby playing a strengthening role.
