PAM Chemical Water Treatment Flocculant White Granules High Polymer Anionic Polyacrylamide​

Polyacrylamide is relatively stable to heat, its solid is softened at 220-230 °C, and its aqueous solution is significantly degraded after 110 °C. Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel, but soluble in water. Polyacrylamide reacts with alkali to produce partially hydrolyzed polyacrylamide, which produces imidization reaction under strong acidity (pH≤2.5), reducing its solubility in water. It can be cross-linked by polynuclear hydroxyl bridge ions of aldehydes (such as formaldehyde) and high-valent metals (such as aluminum, chromium, zirconium, etc.), and is easily degraded by mechanical and (or) oxygen. In oil production, it is mainly used as oil displacement agent, water blocking agent, profile control agent, viscosity increasing agent, drag reducing agent, water treatment agent, etc.

Solubility in water: Under rapid mechanical stirring, it is easily soluble in cold water to form a transparent adhesive solution. Elevating temperature does not affect its solubility, and its dissolution is limited only when the solution concentration increases to high viscosity.
Solubility in other solvents: Solubility of more than 1% in solvents such as glycerol, ethylene glycol, formaldehyde, glacial acetic acid and lactic acid (these substances can be used as plasticizers for polyacrylamide lamination). It can only swell but not dissolve in solvents such as propionic acid and propylene glycol, and cannot be dissolved in solvents such as acetone and hexane.
