Aplicaciones
1. Industrial Circulating Cooling Water Systems
This copolymer acts as a primary scale inhibitor and dispersant in high-hardness, high-alkalinity, and high-chloride circulating water systems in industries such as power generation, chemical plants, steel, and metallurgy. It effectively prevents the deposition of calcium carbonate, calcium sulfate, barium sulfate, silicon scale, and iron oxide, protecting heat exchangers and pipelines from scaling and improving overall system efficiency.
2. Oil and Gas Extraction: Drilling and Completion Fluids
In oil and gas applications, the copolymer serves as a viscosity reducer and shale inhibitor, stabilizing wellbores under high-temperature and high-salinity conditions, including salt and gypsum formations. It ensures drilling fluid stability, reduces fluid loss, and enhances operational safety and efficiency.
3. Boiler and Steam Systems
Used in medium- and high-pressure boiler water treatment, this polymer suppresses scale formation inside boilers and disperses corrosion products such as iron oxide. This prevents deposits from adhering to boiler heating surfaces, effectively avoiding “corrosion under scale” and extending boiler life.
4. Daily Chemical and Textile Industries
As a chelating and dispersing agent, it improves the binding of calcium and magnesium ions, enhancing cleaning efficiency in detergents and preventing redeposition of dirt. It is widely applied in laundry detergents, textile washing, and cleaning formulations, ensuring better performance and product stability.

Key Features of CAS 40623-75-4
1. Excellent Scale Inhibition Efficiency
The copolymer achieves a scale inhibition rate exceeding 95% for calcium carbonate and calcium sulfate. It provides effective protection at low dosages, significantly outperforming traditional polycarboxylic acid-based scale inhibitors.
2. Strong Resistance to Water Quality Interference
It maintains stable performance under harsh conditions, including high salinity, high turbidity, and elevated pH levels. This ensures consistent chemical effectiveness even in complex industrial water systems.
3. Eco-Friendly and Low Toxicity
The polymer is non-toxic, biodegradable, and odorless, with no heavy metals or harmful substances. Its environmental profile surpasses many phosphorus-containing water treatment agents, meeting industrial wastewater discharge regulations.
4. Wide Industrial Adaptability
With adjustable molecular weight and monomer ratio, the copolymer can be customized for different industries and applications, providing flexible solutions for diverse water treatment, oilfield, and industrial chemical requirements.
Advantages of Our Product
1. Cost-Effective Performance
The copolymer’s high efficiency at low dosages reduces chemical consumption and lowers procurement costs. Its long-term stability minimizes the frequency of replenishment and manual maintenance, resulting in significant operational cost savings for industrial water systems and equipment.
2. Enhanced Operational Efficiency
With superior scale inhibition and dispersing capabilities, the polymer reduces equipment cleaning frequency. For example, the cleaning cycle of circulating water heat exchangers can be extended by over 50%, while maintaining optimal heat exchange efficiency, increasing thermal efficiency by 8–12% and reducing overall energy consumption.
3. Universal Adaptability for Harsh Conditions
Resistant to high temperatures, high salinity, and wide pH ranges, this copolymer performs reliably in environments where traditional chemicals struggle. It is ideal for deep oilfield wells, coastal power plants with high-chlorine water, and medium- to high-pressure boilers, eliminating the need for multiple specialized chemicals and simplifying water treatment operations.
