NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing advanced chemical solutions, and among our key offerings is Hydroxyethylidene-1,1-diphosphonic Acid, widely known as HEDP or Etidronic Acid. This powerful organophosphoric acid has become indispensable in various industrial sectors, particularly in water treatment, owing to its exceptional scale and corrosion inhibition properties.

HEDP's primary function in water treatment is to prevent the formation of scale and protect metal surfaces from corrosion. It achieves this by chelating metal ions such as iron, copper, and zinc. These ions, when left unchecked, can lead to scale buildup and accelerate the degradation of equipment. HEDP forms stable, soluble complexes with these metal ions, effectively removing them from the water system and preventing them from depositing on surfaces. This makes it an ideal solution for circulating cooling water systems, low-pressure boilers, and oilfield applications.

The chemical stability of HEDP is a significant advantage. It remains effective even at high pH values and is resistant to hydrolysis and decomposition under normal light and heat conditions. Furthermore, its tolerance to acid, alkali, and chlorine is superior to many other organophosphoric acids. This resilience ensures consistent performance across a wide range of operational parameters. When HEDP is used in conjunction with other water treatment chemicals, such as polycarboxylic acids, it exhibits synergistic effects, leading to enhanced overall water treatment efficacy. This cooperative behavior amplifies its scale and corrosion inhibition capabilities.

Beyond water treatment, HEDP finds extensive use in other industries. In the detergent and cleaning industry, it acts as a chelating agent and dispersant, enhancing cleaning efficiency and preventing scale buildup in household and industrial cleaners. Its ability to stabilize peroxide solutions makes it valuable in the textile and dyeing industries as a peroxide stabilizer and dye-fixing agent. Additionally, its chelating properties are leveraged in cosmetics to improve product stability and performance.

For businesses looking to optimize their water treatment processes and protect their valuable equipment, understanding the benefits of HEDP is crucial. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality HEDP to meet these critical industrial needs. We focus on delivering reliable solutions that contribute to operational efficiency and sustainability for our clients.
