Application and Processing Technology of Polyacrylamide
Polyacrylamide (PAM) is a synthetic polymer widely used in a variety of industrial and environmental applications, primarily for its properties as a flocculant and water treatment agent. SHNChem, a leading polyacrylamides factory, excels in the production and development of high-quality polyacrylamide products, utilizing cutting-edge technology and innovative processing techniques. This article explores the diverse applications of polyacrylamide and the sophisticated processing technology employed by SHNChem to meet global standards.

Processing Technology at SHNChem

The production of polyacrylamide at SHNChem involves several critical stages:

Polymerization: The primary step in polyacrylamide manufacturing is the polymerization of acrylamide monomers. We uses a controlled radical polymerization process that allows for precise control over the molecular weight of the product. This process involves initiators and catalysts under specific conditions of temperature (usually around 25°C to 30°C) and pH to ensure that the polymer chains form correctly without excessive branching or cross-linking, unless desired for specific applications.

Drying: Once polymerization is complete, the polyacrylamide is precipitated out of the reaction mixture and needs to be dried. SHNChem utilizes innovative drying techniques such as spray drying, which helps achieve a consistent granular form while maintaining the integrity of the polymer chains. The drying process reduces the moisture content to less than 10%, which is crucial for the stability and shelf life of the product.

Pulverizing and Granulating: The dried polyacrylamide is then ground into fine powder or granulated to specific particle sizes according to customer requirements. The typical particle size range SHNChem targets is from 100 microns to 2 mm, which facilitates easy handling and dissolution in application processes.

Quality Control: Throughout the manufacturing process, we enforces stringent quality control measures. The molecular weight distribution and charge density of the polyacrylamide are tested using gel permeation chromatography and titration methods. This ensures that each batch meets the specified parameters with a high degree of reproducibility.

Applications of Polyacrylamide

Polyacrylamide's versatile properties make it valuable in a multitude of industries:

Wastewater Treatment: As a flocculant, it helps in the sedimentation or dewatering of sludge in municipal and industrial wastewater treatment plants. The polymer enhances the aggregation of suspended particles, thus facilitating their removal from wastewater.

Oil Recovery: In the oil industry, it is used for enhanced oil recovery (EOR). It increases the viscosity of water injected into oil reservoirs, which improves the sweep efficiency and effectively pushes more oil towards the production wells. SHNChem provides polyacrylamide that can withstand the harsh conditions of oil reservoirs, with formulations stable up to temperatures of 90°C.

Paper Making: In the paper industry, polyacrylamide is used as a retention aid to improve paper quality and reduce fiber loss. It also enhances the strength of the paper by increasing the bonding between fibers.

Mining: It is used in the mining industry to enhance the sedimentation of solids in mineral processing. Its application ensures cleaner and more efficient extraction processes.

Environmental Considerations

SHNChem is committed to environmental sustainability in its polyacrylamide production. The factory employs water recycling techniques and ensures that waste products from the manufacturing process are treated and disposed of responsibly. The use of non-toxic catalysts and energy-efficient processes further minimizes the environmental impact.


Polyacrylamide is a polymer of immense industrial significance, and its effective application hinges on the quality of both the product and the processing technology used in its production. SHNChem, as a leading chemical products factory, stands at the forefront of technological advancement in polymer chemistry. With a focus on quality control, environmental sustainability, and customer satisfaction, we continues to provide superior polyacrylamide solutions tailored to meet the diverse needs of industries worldwide.
