About Polymaleic acid

HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330C. HPMA has obvious threshold effect under high temperature (350C) and high pH (8.3) level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300C with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also be used as additives for cement.

Exceptional Scale Inhibition for Water Treatment Systems

Polymaleic acid is widely recognized for its superior ability to prevent scale formation in industrial water systems, such as cooling towers and boilers. Its unique chemistry enables effective dispersal and stabilization of minerals under high-temperature and alkaline conditions. As a result, it protects and extends the lifespan of crucial system components, boosting operational efficiency and reducing maintenance costs.

Safe Handling and Environmental Compliance

Formulated as a non-toxic and non-corrosive additive, Polymaleic acid is safe for personnel, the environment, and most metallic surfaces. It is fully biodegradable, aligning with stringent environmental regulations in water treatment processes. Storage requirements are straightforward: keep it in a cool, dry, and well-ventilated space to preserve its shelf life of up to 12 months.

FAQs of Polymaleic acid:

Q: How is Polymaleic acid used in industrial water treatment processes?

A: Polymaleic acid is primarily used as a scale inhibitor and dispersant in industrial water systems like cooling towers and boilers. It is added directly to water, where it effectively prevents scale buildup by stabilizing hardness ions and dispersing particles, ensuring smooth system operation and improved equipment longevity.

Q: What are the main benefits of using Polymaleic acid for water treatment?

A: The main benefits include excellent scale inhibition under high temperatures and alkaline conditions, high chemical stability, non-toxicity, environmental friendliness due to its biodegradability, and compatibility with most water treatment chemicals. These properties contribute to reliable protection of equipment and lower maintenance requirements.

Q: When should Polymaleic acid be added to water treatment systems?

A: Polymaleic acid should be dosed continuously or as required, typically at the make-up water point or into circulating water, depending on the systems scale formation risk and operational parameters. Regular dosing ensures consistent protection against scale and fouling.

Q: Where can Polymaleic acid be sourced and in what packaging?

A: Polymaleic acid is produced and exported by SHANDONG FENGFENG CHEMICAL CO., LTD., China. It is commonly supplied in 25 kg plastic drums, but other packaging options are available to meet customer requirements.

Q: What is the process for storing and handling Polymaleic acid safely?

A: Store Polymaleic acid in a cool, dry, well-ventilated area away from sunlight and incompatible substances. Ensure containers are tightly closed when not in use. The product is non-toxic and non-corrosive, making it safe to handle with standard industrial precautions.

Q: Is Polymaleic acid compatible with other water treatment chemicals?

A: Yes, Polymaleic acid is compatible with most water treatment chemicals, allowing it to be integrated seamlessly into existing treatment regimens without causing adverse reactions or reducing efficacy.
