Polyacrylic acid (PAA) and Sodium polyacrylate (PAAS) are used in water treatment, detergents, papermaking, petroleum extraction, and the construction industry.
In the water treatment industry, polyacrylic acid (PAA) and sodium polyacrylate (PAAS) are widely used in industrial circulating water, boiler water, wastewater treatment, and other fields. Although both are polymers, they have different focuses in terms of performance and application, and a reasonable choice is necessary to achieve the best results.
Polyacrylic acid (PAA) vs Sodium polyacrylate (PAAS): The difference in water treatment
Performance | Polyacrylic acid（PAA） | Sodium polyacrylate（PAAS） |
Solubility | Difficult to dissolve in water, needs to be neutralized with alkaline substances before use | Dissolves directly in water, more convenient to use |
Chelation | It has a strong chelating effect and can effectively remove hardness ions such as calcium and magnesium in water. | Slightly weaker chelating effect, but still stable at high pH |
Dispersion performance | Excellent dispersing properties to prevent dirt deposition | Provides better dispersibility to prevent scaling and sedimentation |
Application Environment | Suitable for high hardness and high concentration water treatment systems | Suitable for low to medium hardness water treatment, especially under alkaline conditions |

Applications of Polyacrylic Acid Products
PAA is commonly used as a water treatment agent for scale inhibition, corrosion prevention, and impurity dispersion in water. It can form complex reactions with metal ions and hard water scale, preventing their deposition and scaling, thereby maintaining the smooth and normal operation of pipelines and equipment. Due to the carboxyl groups on the polyacrylic acid molecular chain, which can form hydrogen bonds with water molecules, PAA has good thickening properties. Therefore, it is widely used as a thickening agent for preparing
Case applications of polyacrylic acid:
1. The application of PAA in the coatings industry
Purpose: To form a paint film that protects the substrate from corrosion.
Function: To form a tough paint film through a crosslinking reaction.
Conclusion: A certain paint company has verified through trials that PAA can form a tough film through cross-linking reactions. This film not only effectively protects the substrate from external environmental erosion but also enhances the overall performance of the paint. Additionally, the hydrophilic groups of PAA give it a certain degree of water solubility, facilitating the application and construction of the paint. Polyacrylic acid is commonly used as a film-forming substance in paints, providing excellent adhesion, weather resistance, and chemical
2. The application of PAA in the textile industry
Objective: Improve dyeing effects and printing quality.
Function: As a dispersant and stabilizer.
Conclusion: A certain textile company has verified through trials that our PAA acts as a dispersant and stabilizer during the dyeing and printing processes of textiles, ensuring that dyes and pigments are evenly dispersed within the fabric, thereby enhancing dyeing effects and print quality. It is also used in the coating treatment of textiles to improve their water absorption and retention properties.
Product applications of sodium polyacrylate
PAAS is used as a corrosion inhibitor and scale inhibitor, water quality stabilizer, paint thickener and water-retaining agent, flocculant, drilling mud treatment agent, etc. PAAS is used for the treatment of circulating cold water in copper equipment, and it has a good scale inhibition effect. At a dosage of 100 mg/L, it can form chelates with scaling ions in moderately hard water, allowing them to flow with the water and preventing the formation of iron oxide scale. PAAS is used as a low-solid-phase drilling fluid loss additive. PAAS is a good dispersant. It can be compounded with other water treatment agents for use in oilfield water injection, cooling water, and boiler water treatment.
Case applications of sodium polyacrylate
1. The application of PAAS in the cleaning products industry
Purpose: Used for the production of phosphorus substitutes.
Conclusion: A certain cleaning products company has developed a new product that has been validated through trials with the company's PAAS. The chelating ability of PAAS has advantages such as effectively dispersing dirt, preventing dirt from redepositing on fabrics, and superior acid resistance compared to STPP. It is widely used in low-phosphorus and phosphorus-free laundry detergents.
2. The application of PAAS in the field of water treatment
Purpose: To reduce water hardness and prevent the formation of scale and rust.
Function: As a component of water quality stabilizers.
Conclusion: A certain pipeline company has verified through trial use of our company's PAAS that PAAS prevents the formation of insoluble scale by chelating, dispersing, or distorting the lattice structure of calcium and magnesium ions in water, which would otherwise combine with anions such as carbonate and sulfate. This is of great significance for protecting water pipes from scale corrosion.
Application cases in water treatment:
Case 1: Industrial Recirculating Water System (PAA)
Background: A large chemical company's industrial circulating cooling water system has serious scaling and corrosion issues, affecting equipment lifespan and operational efficiency. Solution: Use high molecular weight polyacrylic acid (PAA) as the main scale inhibitor, in combination with other water treatment agents, to improve water quality stability.
Results: 1. Significant reduction in equipment scaling, with a 20% increase in heat exchange efficiency. 2. System maintenance costs reduced by 30%. 3. Increased water recycling rate, reducing wastewater discharge.
Case 2: Boiler Water Treatment (PAAS)
Background: A certain food processing plant's boiler has been using groundwater for a long time, leading to severe scaling inside the pipes, decreased thermal efficiency, and increased energy consumption.
Solution: Use sodium polyacrylate (PAAS) as a dispersant to prevent the deposition of calcium carbonate and calcium sulfate, while optimizing system operation with a corrosion inhibitor.
Results: 1. Reduced scaling in the boiler heat exchange pipes, with a 15% increase in thermal efficiency. 2. A 25% decrease in operation and maintenance costs. 3. Improved water resource utilization, extending the boiler's service life.
How do we choose between polyacrylic acid and sodium polyacrylate?
1. If your water treatment system faces high hardness water or severe scaling problems, it is recommended to use polyacrylic acid (PAA), which has a stronger chelating effect and can efficiently remove calcium and magnesium ions.
2. If your system operates under neutral or alkaline conditions and requires good dispersibility, it is recommended to choose sodium polyacrylate (PAAS).
No matter what solution you need, our high-quality polyacrylic acid and sodium polyacrylate can help you improve water treatment efficiency, reduce operational costs, and achieve more sustainable water resource management.
