Product Specifications

Technical details and manufacturing context for Industrial Grade Polyacrylamide Flocculant Powder

Definition

Industrial grade polyacrylamide flocculant powder is a synthetic, water-soluble polymer manufactured through polymerization of acrylamide monomers. It serves as a critical chemical agent in industrial processes where solid-liquid separation is required, functioning by bridging suspended particles to form larger aggregates that settle more rapidly. This material is essential in wastewater treatment plants, mining operations, and paper manufacturing for clarifying process water and recovering valuable solids. Its effectiveness depends on molecular weight, charge density, and hydrolysis degree, which are tailored for specific industrial applications.

Typical parameters include molecular weight ranging from 8 to 20 million g/mol, ionic charge from 10% to 60%, hydrolysis degree from 5% to 30%, solid content of at least 90%, bulk density from 0.6 to 0.9 g/cm³, particle size distribution from 0.2 to 1.5 mesh, dissolution time from 30 to 60 minutes at 20°C, viscosity (0.1% solution) from 200 to 800 mPa·s, pH range (1% solution) from 6 to 8, residual monomer content of no more than 0.05% (per GB/T 17514), storage temperature from 0 to 40°C, and shelf life of 24 months under recommended conditions.

These values are reference ranges and must be verified for the specific product grade and application. The material is supplied as a powder and requires proper handling to avoid degradation. Always confirm model-specific specifications and applicable standards with the legal manufacturer or supplier before use.

Working Principle

Polyacrylamide chains adsorb onto suspended particles through electrostatic or hydrogen bonding, creating bridges that aggregate fine particles into larger flocs for efficient sedimentation or filtration. The polymer's long chains extend into the liquid, attaching to multiple particles simultaneously. This bridging mechanism neutralizes surface charges and overcomes repulsive forces, allowing particles to come together. The resulting flocs are denser and settle faster, improving solid-liquid separation. The effectiveness depends on polymer molecular weight, ionic charge, and hydrolysis degree, which influence adsorption and bridging efficiency.
