Polyacrylamide, Polyacrylic amide, PAM, concrete admixture
Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard vitreous solid at room temperature, and its products include glue, latex and white powder, translucent beads and flakes. Good thermal stability. It can be dissolved in water in any proportion, and the aqueous solution is a uniform and transparent liquid.
Polyacrylamide, Polyacrylic amide, PAM
Chemical formula (C3H5NO)n
CAS registration number: 9003-05-8
EINECS Accession Number: 231-545-4
Water solubility: soluble in water
Density: 1.302 g/cm3 (23C)
Appearance: Hard glassy solid at room temperature, products include glue, latex and white powder, translucent beads and flakes, etc.
Use features
1. Flocculation: PAM can make suspended substances neutralize by electricity, bridge adsorption, and flocculate.
2. Adhesion: It can play an adhesive role through mechanical, physical and chemical effects.
3. Resistance reduction: PAM can effectively reduce the frictional resistance of the fluid. Adding a small amount of PAM to the water can reduce the resistance by 50-80%.
4. Thickening: PAM has thickening effect under neutral and acid conditions. When the pH value is above 10, PAM is easy to hydrolyze. Thickening will be more pronounced in a semi-reticular structure.
concrete application
It can effectively improve the impermeability and wear resistance of concrete;
The use of polyacrylamide in combination with ferrous sulfate can significantly improve the water retention performance of concrete, and at the same time can significantly reduce the water separation rate of concrete.
