What is polyacrylamide?

Polyacrylamide is a water-soluble polymer that is insoluble in most organic solvents. Classified by ionic characteristics, it falls into four main types: non-ionic, anionic, cationic, and amphoteric. Possessing excellent flocculation properties and the ability to reduce interfacial friction, polyacrylamide finds extensive application across industrial sectors including water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, light industry and textiles, and construction. It is often referred to as the “industrial flavour enhancer”. Polyacrylamide possesses several key characteristics 1. Flocculation: Promotes flocculation of suspended solids through electrostatic neutralisation and bridging adsorption. 2. Binding: Exerts adhesive effects via mechanical, physical, and chemical interactions. 3. Drag Reduction: Effectively lowers fluid friction; adding trace amounts of PAM to water reduces resistance by 50-80%. 4. Thickening property: Exhibits thickening effects under both neutral and acidic conditions, though hydrolysis occurs readily at pH values above 10. Thickening becomes markedly more pronounced when adopting a semi-reticulated structure. Guidelines for the use of polyacrylamide 1. Anionic flocculants are typically employed in water treatment, whilst cationic variants are generally utilised for sludge dewatering. 2. Anionic flocculants are usually prepared as aqueous solutions of approximately 0.1% concentration, whereas cationic flocculants may be formulated at concentrations ranging from 0.1% to 0.5%. 3. When preparing the solution, first add water to the dissolution tank before activating the mixer. Then slowly add the PAM along the vortex; avoid rapid bulk addition as this may cause clumping and prevent dissolution. 4. After adding the PAM, continue stirring for at least 30 minutes to ensure complete dissolution. 5. Use the solution promptly after dissolution: anionic types should be used within 36 hours, while cationic types should be utili The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
