Polyacrylamide Powder

Polyacrylamide Powder: High-Efficiency Polymer Solution for Industrial Multisector Applications

As a versatile water-soluble polymer, polyacrylamide (PAM) has become an indispensable core auxiliary in global industrial production, and polyacrylamide powder, with its stable performance, convenient storage, and flexible application, stands out as the most widely used form of PAM products. Different from emulsion or liquid PAM, polyacrylamide powder boasts excellent mobility, controllable dissolution rate, and adjustable molecular structure, which can be customized according to the actual needs of different industries-from water treatment to oil extraction, from mining to papermaking, it injects efficient and economical power into every link of industrial production. This introduction will comprehensively interpret polyacrylamide powder from multiple dimensions such as product essence, technical specifications, scenario applications, core advantages, and quality control, revealing its unique value that is different from ordinary polymer products.

Product Essence: What Makes Polyacrylamide Powder Unique?

Polyacrylamide powder is a linear synthetic polymer.
Formula: (CH₂CHCONH₂)ₙ.
CAS No.: 9003-05-8
This product appears as a white or off-white, free-flowing solid powder. It is odorless, non-corrosive, and non-toxic, exhibiting excellent solubility in water (though it is insoluble in organic solvents such as ethanol and acetone).
Its core advantages lie in its adjustable molecular weight (ranging from 1 million to 30 million Daltons) and its modifiable functional groups. Depending on industrial requirements, it can be processed into four distinct types-anionic, cationic, non-ionic, and amphoteric-each possessing unique performance characteristics that enable them to adapt to a wide variety of application scenarios.
Compared to other forms of polyacrylamide (PAM), the powder form offers significant advantages in terms of storage and transportation: when kept in a dry, well-ventilated environment, it boasts a shelf life of up to 12 months and is resistant to degradation. Furthermore, due to its compact volume and light weight, it effectively reduces transportation costs by 30% to 40% compared to liquid PAM. Concurrently, its dissolution rate can be regulated by adjusting the particle size (ranging from 40 to 100 mesh), thereby effectively preventing the clumping issues often encountered during the dissolution of traditional powder products, making the operational process more convenient and efficient.
The polyacrylamide powder produced by Henan Saifu Company utilizes advanced low-temperature copolymerization technology; this technology not only ensures the uniformity of the molecular weight distribution but also enhances the overall stability of the product.

Technical Specifications: The Core Criterion for Polyacrylamide Powder Selection

The performance of polyacrylamide powder is directly determined by its technical parameters, which also determine its applicability to different industrial scenarios and market positioning. Below are the key technical indicators that affect the quality and application effect of polyacrylamide powder, helping you accurately select products that meet your needs:

Molecular Weight (1-30 Million Daltons):

The core parameter affecting the flocculation, thickening, and adsorption performance of polyacrylamide powder. Low molecular weight (1-8 million) products are suitable for papermaking retention aids, textile sizing agents, and low-turbidity water treatment; medium molecular weight (8-18 million) is widely used in industrial wastewater clarification and coal washing; high molecular weight (18-30 million) is mainly used in oil extraction, heavy metal wastewater treatment, and sludge dewatering . The higher the molecular weight, the stronger the bridging effect between particles, but the dissolution difficulty also increases accordingly.

Charge Property & Density: Divided into four types, which is the key to matching different application scenarios:

• Anionic Polyacrylamide Powder: Hydrolysis degree 10%-40%, with negative charge groups, suitable for neutral to alkaline environments, mainly used in inorganic wastewater treatment and mineral processing ;
• Cationic Polyacrylamide Powder: Ionicity 10%-80%, with positive charge groups, suitable for organic wastewater treatment and sludge dewatering ;
• Non-Ionic Polyacrylamide Powder: No charge, hydrolysis degree 5%-10%, suitable for high-salt, high-acidity/alkalinity complex wastewater ;
• Amphoteric Polyacrylamide Powder: Contains both positive and negative charge groups, suitable for variable water quality scenarios, with strong adaptability .

Particle Size (40-100 Mesh):

Determines the dissolution rate of polyacrylamide powder. 40-60 mesh products dissolve quickly (5-10 minutes) and are suitable for scenarios requiring rapid treatment; 80-100 mesh products dissolve slowly but have more stable performance, suitable for high-precision water treatment and oil extraction scenarios .

Key Quality Indicators:

Solid content ≥90%, insoluble content ≤0.2%, residual monomer content ≤0.05% . High-purity products (residual monomer ≤0.05%) are suitable for drinking water treatment and food industry, while ordinary industrial-grade products meet the needs of general wastewater treatment and mining scenarios .

Multi-Scenario Application: Polyacrylamide Shines in Various Industries

Polyacrylamide powder is favored by various industries due to its adjustable performance and convenient use, and its application scope covers water treatment, oil & gas, mining, papermaking, agriculture, and other fields , becoming a "multi-functional assistant" in industrial production. Below are the core application scenarios and practical effects of different types of polyacrylamide:

• Water Treatment: The Core Flocculant for Efficient Purification

Water treatment is the largest application field of polyacrylamide powder, accounting for more than 60% of the total demand . Different types of polyacrylamide powder are targeted at different water quality conditions, achieving precise purification:

1. Municipal Wastewater: Anionic and non-ionic polyacrylamide powder are used in combination to aggregate suspended solids, reduce turbidity by 90% and COD by 70%, and reduce the dosage of inorganic flocculants (such as PAC) by 30% ;

2. Industrial Wastewater: Cationic polyacrylamide powder is used for organic wastewater (printing and dyeing, pharmaceutical, food processing) to flocculate organic colloids, with a decolorization rate of up to 92% ; anionic polyacrylamide powder is used for inorganic wastewater (steel, electroplating) to remove heavy metal ions, with a removal rate of more than 90% ;

3. Drinking Water Purification: High-purity non-ionic polyacrylamide powder (residual monomer ≤0.05%) is used to improve water clarity, avoiding secondary pollution and complying with drinking water safety standards .

• Oil & Gas Industry: The Key Auxiliary for Efficient Oil Extraction

In oil extraction, high molecular weight anionic polyacrylamide powder (18-30 million) is the core auxiliary agent, mainly used in three aspects : drilling fluid additives to reduce fluid loss and protect the well wall; flooding agents to improve water viscosity, increase oil recovery rate by 10%-15%; and oil-water separation agents to quickly separate crude oil from produced water, reducing oil content in water to below 10 mg/L. In shale gas extraction, it is used as a drag reducer to reduce pipeline friction and improve transportation efficiency.

• Mining & Metallurgy: The Efficient Aid for Solid-Liquid Separation

In coal mining, metal mining, and other fields, polyacrylamide powder is used as a flocculant and filter aid to accelerate the settlement of tailings and ore pulp, improve solid-liquid separation efficiency . For example, in coal washing wastewater treatment, anionic polyacrylamide powder can quickly aggregate coal slime particles, reduce sludge water content to below 65%, and recover valuable coal resources, reducing environmental pollution and resource waste .

• Other Fields: Versatile Applications Beyond Expectations

1. Papermaking Industry: Cationic polyacrylamide powder is used as a retention and drainage aid to improve the retention rate of fibers and fillers by 20%-30%, reduce paper breaking rate, and improve paper strength ; low molecular weight anionic polyacrylamide powder is used as a sizing agent to enhance the water resistance of paper;
