Polyacrylamide widely used in the construction industry can also show their talents. Paint their own water retention belongs to their inherent attributes, why add polyacrylamide?

Polyacrylamide is a polymer electrolyte, it can be said that the polymer medium, in water or polar solvents ionization of many ion groups, water molecules into the network structure and these ions with hydrogen bonding and be Adsorption, firmly in the network, because the network is flexible, which can accommodate a large number of water molecules.

So why choose polyacrylamide as a water-retaining agent to add it?

Water-retaining agents are mainly carboxymethyl cellulose, hydroxyethyl cellulose, polyvinyl alcohol, etc., but these water-retaining agent is expensive. Polyacrylamide (PAM) is a copolymer of acrylamide homopolymer or copolymerized with other monomers. In the industry, polymers containing more than 50% acrylamide (AM) monomers are known as PAM, which is water-soluble Polymer used in drunk one of the broad varieties, said white, drunk is the main price is cheap.

Why do you add polyacrylamide to the paint? What can they do?

The ability of the coating to be applied to the surface of a medium to maintain the free water therein does not directly affect the ease of construction and the quality of the construction wall. The water retention of the coating is derived from the affinity of the coating for free water. The free water in the paint is relatively free and susceptible to the influence of external factors. After contact with the wall, the difference of water at the interface leads to the diffusion of the paint water to the wall, and the thermal activity of the free water molecules is accelerated and the diffusion speed is accelerated, The results of these effects allow free water to be removed from the coating.

Bo Yuan water purification materials research strength, for market demand, directional technology development, its leading products are: polyacrylamide series; poly aluminum chloride series; polymerization of ferric sulfate series; ferrous sulfate series; environmental protection machinery and equipment series.
