Anionic Polyacrylamide (APAM) Product Introduction
Product Overview:
Anionic Polyacrylamide (APAM) is a versatile chemical product widely applied in various industrial fields, particularly excelling in water treatment processes. It appears as white powder with a molecular weight ranging from 3 million to 25 million. APAM boasts excellent water solubility, dissolving readily in water but not in organic solvents. Its effective pH range spans from 6 to 10, exhibiting properties of a high polymeric electrolyte in neutral to alkaline media. It is sensitive to saline electrolytes and can cross-link with high-valent metal ions to form insoluble gels.
Applications in Water Treatment:
Industrial Wastewater Treatment: APAM is highly effective in treating industrial wastewaters containing suspended particles, especially those with high concentrations and positively charged particles, such as wastewaters from steel plants, electroplating factories, metallurgical processes, and coal washing operations. It performs well in neutral to alkaline environments.
Drinking Water Treatment: Many municipal water treatment plants source their water from rivers, which may contain high levels of silt and minerals, resulting in turbidity. Even after sedimentation and filtration, the water may still not meet quality standards. APAM, used as a flocculant, requires only 1/50 of the dosage compared to inorganic flocculants but achieves several times the effect. For rivers heavily polluted with organics, combining inorganic flocculants with cationic polyacrylamide yields better results.
Starch and Ethanol Factories: In starch factories, APAM aids in recovering lost starch and distiller's grains by flocculating and precipitating starch particles. The precipitate can be pressed into cakes for use as feed. Similarly, in ethanol factories, APAM facilitates dehydration and recovery of alcohol through pressure filtration.
River Sediment Settling: APAM is used to accelerate the settling of river sediments.
Papermaking Wastewater Treatment: In the papermaking industry, APAM enhances flocculation and settlement during wastewater treatment and reduces moisture content in sludge cakes, enhancing overall efficiency.
Drilling Mud Material: In oilfield exploration, APAM serves as an additive to improve drilling speed, reduce drill bit wear, extend drill bit life, and lower costs.
Oil Recovery Agent: APAM effectively modifies the mobility and flow rate of injected water, enhancing the viscosity and compatibility of the fluid, thereby significantly increasing the permeability of underground formations. It is particularly beneficial in secondary and tertiary oil recovery processes, boosting oil production by approximately 200 tons per application.
Petroleum Industry Applications: Within the petroleum sector, APAM finds extensive use in oil extraction, drilling mud formulation, waste mud treatment, water channeling prevention, friction reduction, and enhanced oil recovery techniques.
Example Scenario: In coal washing processes, large volumes of wastewater are generated. Direct discharge poses environmental risks, necessitating clarification and recycling. Recovering the coal slime from this wastewater is also valuable. Natural settlement is inefficient and time-consuming, yielding unclear water. APAM significantly accelerates this process, ensuring clearer water and efficient resource recovery.
In conclusion, anionic polyacrylamide (APAM) stands as a crucial chemical agent in multiple industries, particularly in water treatment and resource recovery, due to its unique properties and broad applicability.
Product Characteristics of Anionic Polyacrylamide:
Excellent Solubility and High Viscosity: Anionic polyacrylamide boasts exceptional solubility, high viscosity, and robust tensile strength. It is flammable yet produces little to no smoke and no unpleasant odor upon burning. It is also non-toxic.
Stable Performance: This product maintains consistent quality, eliminating the need for repeated formula adjustments that are often required with other plant gums and ordinary starches due to variations in origin and aging, which can lead to unstable product quality in the incense industry.
Superior Finish and Durability: Incense products made with anionic polyacrylamide exhibit a smooth and even surface, excellent molding, and resistance to breakage.
Cold Water Dispersibility: Its ability to gelatinize in cold water eliminates the need for boiling. Simply mix the material evenly with water and stir to produce. Furthermore, the mixed material remains usable even after prolonged storage without hardening, effectively conserving energy and facilitating production operations.
Packaging and Storage of Anionic Polyacrylamide:
This product is a non-toxic powdered granule that is susceptible to air exposure, which can compromise its quality. Therefore, it should not be stored in damp or sunny environments. During loading, unloading, and transportation, it is essential to minimize contact between polyacrylamide (PAM) and metals such as iron and copper. Diaphragm pumps and piston pumps are recommended for use. The storage life of solid granular or powdered polyacrylamide is 2 years.
By adhering to these guidelines, you can ensure the optimal performance and longevity of your anionic polyacrylamide products.
