High purity polyacrylamide product introduction:
Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce friction resistance between liquids, according to ionic characteristics can be divided into anionic, cationic, non-ionic and amphoteric.
Researched by water purification experts, it is generally believed that high purity polyacrylamide flocculation principle is:
(1) because of its polar gene-amide group, it is easy to absorb on the surface of sediment particles by its hydrogen-binding effect;
(2) because of its long molecular chain, large-scale long chain has a huge adsorption surface area in water, so the flocculation effect is good, using long chains to bridge between particles to form large particles of flocculent and accelerate sedimentation.
(3) With the aid of flocculation-coagulation aid of high purity polyacrylamide, double ionization compression may occur during the sludge coagulation process of water purification, which reduces the aggregation stability of particles. Under the action of molecular gravity, simple anions of dispersed phase can be replaced by anionic groups of polymers;
(4) substances in the composition of polymers and natural water, and suspended substances in water, or The chemical interaction between the ions of hydrolytic coagulant added before it may be a complexation reaction;
(5) Because the molecular chains are fixed on the surface of different particles, the polymer bridges are formed between the solid particles.
