Description
Uses of polyacrylamide anionsAnionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation and sedimentation, sedimentation and clarification of various industrial wastewaters, such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. Mud dehydration, etc. It can also be used for drinking water clarification and purification.
Polyacrylamide is a linear organic polymer, but also a polymer water treatment flocculant products, specifically can adsorb suspended particles in water, between the particles to play a role in linking bridges, so that fine particles form a relatively large floc, and accelerate the speed of precipitation. This process is called flocculation because of its good flocculation effect PAM as a flocculant for water treatment and is widely used in sewage treatment.
Polyacrylamide (PAM) is a linear organic polymer, and it is also a polymer water treatment flocculant product. It can absorb suspended particles in water and play a role of link bridging between particles to make fine particles Larger flocs are formed and the speed of precipitation is accelerated. This process is called flocculation, because of its good flocculation effect, PAM is used as a flocculant for water treatment and is widely used in sewage treatment.
Polyacrylamide is an important water-soluble polymer, and has valuable properties such as flocculation, thickening, shear resistance, resistance reduction, and dispersibility. These properties vary with the derivative ions. Therefore, we mainly see it being widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, paper making, textile, sugar making, medicine, environmental protection, building materials, agricultural production and other departments.
Under normal circumstances, the use effect of polyacrylamide will increase the flocculation effect with the increase in the amount of use, but when the amount is too much, the effect will become lower, and it will become a stable colloid again. The second is the flocculation time: the combination of organic flocculants and inorganic flocculants has the biggest feature of obtaining flocs with the largest particles, and the oil droplets can be agglomerated or adsorbed out.
If the speed is too slow and the time is too short, the flocculant cannot fully contact the solid particles, which is not conducive to the flocculant to capture the colloidal particles; and the concentration distribution of the flocculant is not uniform, which is not conducive to the function of the flocculant. The effect of polyacrylamide is also related to the water temperature: when the water temperature is low, the reaction speed is too slow, the hydrolysis time increases, which affects the amount of water to be treated. At the same time, the tearing effect of the high viscosity on the flocculant will also make the flocs smaller. When the water temperature is high, the reaction speed is too fast, forming small flocs.
The role of polyacrylamide anionAnionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation and sedimentation, sedimentation and clarification of various industrial wastewaters, such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. Mud dehydration, etc. It can also be used for drinking water clarification and purification. Because its molecular chain contains a certain number of polar groups, it can absorb solid particles suspended in water, bridge between particles or aggregate particles to form large flocs through charge neutralization, so it can accelerate particles in suspension. The sedimentation has a very obvious effect of accelerating the clarification of the solution and promoting filtration. Polyacrylamide is a kind of flocculant, English code (PAM). Main classification: Anionic Polyacrylamide (APAM), Cationic Polyacrylamide (CPAM), Nonionic Polyacrylamide (NPAM)
