the equivalent model  anionic polyacrylamide emulsion of NALCLEAR 7768 from Chinafloc 

NALCLEAR 7768 is a kind of anionic polyacrylamide emulsion with medium hydrolysis degree and hih molecualr weight ,mainly used for wastewater treatment and other applicaitons.

Water Treatment

• Sewage Treatment: In sewage treatment plants, anionic polyacrylamide emulsion is widely used for sludge dewatering and solid - liquid separation. It can effectively adsorb and bridge with the suspended solids and organic matter in the sewage, forming large - size flocs. This helps to improve the sedimentation and filtration efficiency, making the effluent clearer and reducing the water content of the sludge. For example, in the treatment of domestic sewage, the addition of anionic polyacrylamide emulsion can significantly improve the treatment effect and reduce the load on subsequent treatment processes.
• Industrial Wastewater Treatment: Many industrial wastewaters contain various pollutants such as heavy metals, dyes, and oils. Anionic polyacrylamide emulsion can be used to treat these wastewaters. It can react with the pollutants through electrostatic attraction and adsorption, causing them to precipitate or flocculate, thereby achieving the purpose of removing pollutants. For instance, in the dyeing and printing industry, anionic polyacrylamide emulsion can effectively remove dyes from wastewater, reducing water pollution.

Paper Industry

• Retention and Drainage Aid: In the paper - making process, anionic polyacrylamide emulsion is used as a retention and drainage aid. It can improve the retention rate of fine fibers, fillers, and additives in the paper - making slurry, reducing their loss in the white water. At the same time, it can also accelerate the drainage of water from the slurry, improve the forming speed of the paper web, and increase the production efficiency of the paper machine. This helps to improve the quality of the paper and reduce production costs.
• Paper Strengthening Agent: Anionic polyacrylamide emulsion can also be used as a paper strengthening agent. It can form a network - like structure on the surface of the paper fibers, enhancing the bonding force between the fibers and improving the physical strength of the paper, such as tensile strength, tear strength, and burst strength. This is especially important for high - strength papers such as packaging paper and kraft paper.

Oil and Gas Industry

• Enhanced Oil Recovery: In the oil and gas industry, anionic polyacrylamide emulsion is widely used in enhanced oil recovery (EOR) processes. It is injected into the oil - bearing formation with water to improve the viscosity of the injection water and adjust the water - oil mobility ratio. This helps to improve the sweep efficiency of the injection water, enabling it to more effectively displace crude oil and increase the oil recovery rate. In some oil fields, the use of anionic polyacrylamide emulsion in EOR has achieved good results and increased oil production.
• Drilling Fluid Additive: Anionic polyacrylamide emulsion can also be used as an additive in drilling fluids. It can improve the viscosity and stability of the drilling fluid, prevent wellbore collapse, and reduce the friction between the drill bit and the wellbore. This helps to improve the efficiency of drilling operations and protect the wellbore environment.

Mining Industry

• Ore Flotation: In the mining industry, anionic polyacrylamide emulsion is used in the flotation process of ores. It can be used as a flotation aid to improve the selectivity and recovery rate of ores. By adjusting the surface properties of the ore particles, anionic polyacrylamide emulsion can make the valuable ore particles easier to adhere to the bubbles and be floated, while the gangue particles are left in the pulp, thereby achieving the separation of valuable ores and gangue.
• Tailings Treatment: After the extraction of valuable ores, the remaining tailings need to be properly treated. Anionic polyacrylamide emulsion is used to treat the tailings slurry to promote the settlement of fine - grained tailings particles. This helps to separate the solid tailings from the water, reduce the volume of the tailings, and facilitate the safe disposal and storage of the tailings. At the same time, the treated water can be recycled, reducing water consumption and environmental pollution.

Textile Industry

• Dyeing and Finishing: In the textile industry, anionic polyacrylamide emulsion is used in the dyeing and finishing process. It can be used as a leveling agent and a fixing agent to improve the dyeing effect and color fastness of fabrics. The anionic groups in the emulsion can interact with the cationic dyes, making the dyes more evenly distributed on the fabric surface and improving the color uniformity. At the same time, it can also form a protective film on the fabric surface, improving the color fastness of the fabric to washing and friction.
