For polyacrylamide this product, the use of users have said good, of course, the price of polyacrylamide is not expensive. Is not the higher the price of the product, the better the use of the product?
The answer is: NO!
Polyacrylamide price and molecular weight, ionicity, hydrolysis, production of raw materials and so on. The use of different industries, product models are different, the price will not be the same. If simple urban wastewater treatment, you choose expensive cationic 50 ionic degree of polyacrylamide, the price is high, the treatment effect will not have cheap anionic 12 million molecular weight polyacrylamide good. This shows that the use of different industries, there is no way to compare the price of the product, but also proves that it is not the higher the price the better the effect, mainly to choose the right model.
Even if the same industry, the regional location of the different industries, the nature of the sewage will not be the same. Then high turbidity and low turbidity sewage, the use of the same polyacrylamide, but the molecular weight and degree of hydrolysis will not be the same, low turbidity water using low molecular weight and low hydrolysis is very good treatment, if you buy high molecular weight polyacrylamide price is much higher, but the treatment effect is not much better, this is also incorrect selection of waste, which also proves that the higher the price of polyacrylamide does not mean that the better the treatment effect. This also proves that the higher the price of polyacrylamide does not mean the better the treatment effect.
Polyacrylamide (PAM) use characteristics
1) Flocculation: PAM can make the suspended material flocculate through electric neutralisation and bridging adsorption.
2) Adhesion: PAM can be mechanically, physically and chemically bonded.
3) Reducing resistance: PAM can effectively reduce the friction resistance of the fluid, adding a trace of PAM in the water can reduce resistance 50-80%.
4) Thickening: PAM has thickening effect in neutral and acid conditions, when the PH value is above 10 PAM is easy to hydrolyse. When the PH value is above 10, PAM is easy to hydrolyse, and when it is semi-network structure, the thickening will be more obvious.
Polyacrylamide (PAM) role of the principle of introduction
1) Flocculation principle: PAM is used for flocculation, with the flocculated species surface properties, especially the kinetic potential, viscosity, turbidity and pH value of the suspension, the kinetic potential of the particle surface, is the reason for the particle blocking the addition of the surface charge opposite PAM, can speed up the reduction of the kinetic potential and cohesion.
2) Adsorption bridging: PAM molecular chain fixed on the surface of different particles, the formation of polymer bridges between the particles, so that the particles form aggregates and settle.
3) Surface adsorption: the polar groups on the PAM molecules are adsorbed by the particles.
4) Enhancement: PAM molecular chains and the dispersed phase through a variety of mechanical, physical, chemical and other effects, the dispersed phase will be linked together to form a network, so as to play a role in the enhancement.
