20-100mesh Anionic Polyacrylamide Powder White Granule For Sewage Water Treatment

High Molecular Weight Medium Anionic Polyacrylamide Powder For Road Soil Stabilizer

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N'-methylenebisacrylamide. In the cross-linked form, the possibility of the monomer being present is reduced even further. It is highly water-absorbent, forming a soft gel when hydrated, used in such applications as polyacrylamide gel electrophoresis, and can also be called ghost crystals when cross-linked, and in manufacturing soft contact lenses. In the straight-chain form, it is also used as a thickener and suspending agent.

What is the Functional Principle of Polyacrylamide?

• Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization.
• Reinforcing Mechanism: PAM molecule chain and dispersed phase form bridging bond, ion bond, and a covalent bond to increase combination strength.

Advantages for Anionic Polyacrylamide in Soild Stabilization:

• Provides quick stabilization where vegetation has yet to be established
• Promotes flocculation (reduces settling time) of smallest particles
• Increases soil pore volume and permeability, thus decreasing imperious cover
• Less obtrusive than some conventional measures - doesn’t interfere with construction machinery/activity
• The material is specifically designed for the soil, waters, and other on-site characteristics
• May prevent costly repair and reshaping of rilling or failing slopes

• Re-application may not be necessary for several months if treated areas are mulched
