Polymer Polyacrylamide Flocculant As Based Soil Stabilizer

Polyacrylamide (PAM) is a functional polymer copolymerized by acrylamide and acrylate. Due to its excellent flocculation, thickening, bonding, rheology modification and other properties, it is widely used in water treatment, petroleum, mining, agriculture and other fields. In the application of soil stabilizers, polyacrylamide has unique properties and functions, which can effectively improve the stability and erosion resistance of soil.

1. Flocculation of polyacrylamide
The particles in the soil usually have negative charges, and there is repulsion between each other, which makes the soil loose and easy to erode. Polyacrylamide combines with soil particles through its positively charged groups to form larger floccules, thereby reducing the repulsion between particles and enhancing the structural stability of the soil. At the same time, the polymer chain of polyacrylamide can be adsorbed on the surface of soil particles to form a dense protective film that effectively resists rain erosion.

2. Thickening effect of polyacrylamide
In the application of soil stabilizers, polyacrylamide can be used as a thickener. By increasing the consistency of the soil, the loss of soil particles under gravity can be reduced, reducing the risk of soil erosion. In addition, the polymer chain of polyacrylamide can be tightly combined with soil particles to form a gel-like structure, further enhancing the soil's ability to resist erosion.

3. The bonding effect of polyacrylamide
Polyacrylamide has excellent bonding properties and can bond soil particles of different particle sizes together to form a highly stable aggregate. This aggregate has good anti-erosion properties and can effectively resist wind erosion and water erosion. In addition, polyacrylamide can also combine with organic matter in the soil to form a more stable organic-inorganic complex, further improving the stability and fertility of the soil.

4. The rheological modification effect of polyacrylamide
In the application of soil stabilizers, polyacrylamide can also be used as a rheological modifier. By changing the rheological properties of the soil, the fluidity and deformability of the soil under gravity can be reduced, thereby reducing the possibility of soil erosion. At the same time, polyacrylamide can also reduce the permeability of the soil and reduce the risk of water loss.
