Besfloc K4032 is a kind of
anionic polyacrylamide with slight charge and high molecular weight mainly used for water treatment and mineral processing ,Chinafloc A0310 can replace of it with good performance.
Anionic polyacrylamide with slight charge and high molecular weight has a wide range of applications in various industries due to its unique properties. The main applications are as follows:
Coagulation and Flocculation: In water treatment plants, it is used to remove suspended solids, colloidal substances, and some organic matter from water. The anionic groups on the polymer chain can adsorb onto the surface of positively charged particles in water through electrostatic attraction. The high - molecular - weight chains then bridge the particles together, forming large flocs. These flocs are easy to settle or be filtered out, thereby improving the clarity and quality of water. It is particularly effective in treating water with a high content of inorganic suspended solids, such as in the treatment of river water or well water.
Sludge Dewatering: In wastewater treatment plants, after the biological treatment process, a large amount of sludge is produced. Anionic polyacrylamide is added to the sludge to improve its dewatering performance. The polymer helps to bind the fine sludge particles together, forming larger aggregates. This makes it easier for the water in the sludge to be separated during the dewatering process, such as by mechanical pressing or filtration, resulting in a drier sludge cake and reducing the volume of sludge for disposal.
Retention and Drainage Aid: In the paper - making process, anionic polyacrylamide is used to improve the retention of fine fibers, fillers, and other additives. It adsorbs onto the surface of these substances, helping to keep them in the paper - forming web and preventing them from being lost in the white water system. At the same time, it can also improve the drainage performance of the paper - making slurry. The high - molecular - weight chains of the polymer can form a network structure in the slurry, which accelerates the drainage of water, thereby increasing the production speed of the paper machine and improving production efficiency.
Paper Strength Enhancement: It can also enhance the physical strength of paper. The anionic polyacrylamide molecules can interact with the cellulose fibers in the paper, improving the bonding between the fibers. This leads to an increase in the tensile strength, tear strength, and burst strength of the paper, making the paper more durable and suitable for various applications.
Enhanced Oil Recovery: In the oil and gas industry, anionic polyacrylamide is widely used in enhanced oil recovery (EOR) processes. It is injected into the oil - bearing formation along with water. The high - molecular - weight polymer can increase the viscosity of the injected water, improving the sweep efficiency of the water in the reservoir. This helps to displace more oil from the pores of the rock and improve the oil recovery rate. Additionally, the anionic groups on the polymer can interact with the rock surface and oil - water interface, reducing the interfacial tension and further facilitating the displacement of oil.
Drilling Fluid Additive: It is used as an additive in drilling fluids. Anionic polyacrylamide can improve the viscosity and rheological properties of the drilling fluid, which helps to carry cuttings out of the wellbore and suspend them in the fluid. It also helps to form a thin and stable mud cake on the wellbore wall, preventing fluid loss and maintaining the stability of the wellbore.
Ore Flotation: In mineral processing, anionic polyacrylamide is sometimes used in the flotation process. It can be used as a depressant or modifier. As a depressant, it can selectively adsorb onto the surface of certain gangue minerals, increasing their hydrophilicity and preventing them from being floated, while allowing the valuable minerals to be floated normally. This helps to improve the selectivity of the flotation process and increase the recovery rate of valuable minerals.
Tailings Management: For the treatment of mine tailings, anionic polyacrylamide is used to promote the settlement of fine - grained tailings particles. It forms flocs with the tailings, which accelerates the sedimentation process and reduces the turbidity of the tailings slurry. This is beneficial for the safe storage and disposal of tailings and helps to protect the environment around the mine.
