Polyacrylamide is one of the important water-soluble Polymers and has valuable properties such as flocculation, thickening, shear resistance, drag reduction and dispersion.
Polyacrylamide molecular weight
The molecular weight of Polyacrylamide mainly refers to the length of the molecular chain, the higher the molecular weight, the longer the molecular chain, the greater the viscosity of the polyacrylamide solution, the greater the resistance in the solution. It should be noted that the molecular weight is not the larger the thicker the product effect is better, the actual situation is to be based on wastewater experiments to determine its effect.PAM molecules are polymerized by more than 100,000 acrylamide or sodium acrylate molecules (the molecular weight of acrylamide is 71, the molecular weight of PAM containing 100,000 monomers is 7.1 million).Usually, PAM with high molecular weight has better flocculation performance when used as a Flocculant.
pam model use distinction: usually, the use of anionic polyacrylamide for wastewater treatment, the use of cationic polyacrylamide for sludge dewatering treatment; the use of anionic polyacrylamide mainly rely on the molecular weight of the distinction, while the cationic polyacrylamide is to distinguish the use of ionic degree.
Ionicity of polyacrylamide
Ions are charged particles formed by atoms or groups of atoms as a result of the loss or gain of electrons. Ionicity refers to the nature of the charge of the ions of a chemical reagent whether it is positive or negative, and the density of the charge it carries. The ionicity of a polyacrylamide is then usually the cationic polyacrylamide ionicity, which refers to the ionic charge density of the cationic polypropylene coolamine. Usually in the industry, cationic polyacrylamide model is mainly to the ionic degree to distinguish products.
Cationic polyacrylamide (CPAM) is made of cationic monomer and acrylamide monomer copolymerization, according to the degree of ionization, can be roughly divided into: strong cationic, medium cationic, weak cationic.
The ionicity of the products circulating in the market is generally 10%-60%, the larger the ionicity, the smaller the molecular weight, which also determines the price of the products, and the ionicity also determines the compactness of the flocs, water content and other issues. Ionicity size will also affect the cost and price of the product, the higher the ionicity, the higher the price of the product.
So, in the choice of cationic polyacrylamide, how to determine the ionicity of the product model, is not the higher the ionicity of the effect is better?
