HEDP-Na4 (tetrasodium hydroxyethylidene diphosphonate) is the sodium salt of hydroxyethylidene diphosphonic acid (HEDP), with the chaical formula C₂H₄O₇P₂Na₄, and the molecular weight of 294.It is an excellent inhibitor of calcium carbonate scaling, and it is used in the following main areas:
HEDP-Na4 Main applications

Water treatment: HEDP-Na4 is widely used in low-pressure boiler water treatment and circulating water treatment, which can effectively prevent the precipitation and scaling of minerals in water.
Industrial cleaning: In industrial municipal cleaning water, HEDP-Na4 can be used as metal corrosion inhibitor to prevent corrosion of metal surfaces.
Swimming Pool Sterilization: It is also used in the sterilization treatment of swimming pools to ensure the safety of water quality.
Other industrial applications: HEDP-Na4 is used as scale and corrosion inhibitor in electric power, chaical industry, metallurgy, fertilizer, etc. It is suitable for industrial circulating cooling water, oil field water injection and oil pipeline.

HEDP-Na4 Performance Characteristics

Appearance: HEDP-Na4 is white powder, easily soluble in water, with good transportation and storage.
Chaical stability: it can maintain good corrosion and scale inhibition effect under high taperature (up to 250℃), and can form stable complexes with many metal ions (such as iron, copper, zinc) to dissolve the oxides on the metal surface.

Safety of HEDP-Na4

HEDP-Na4 is weakly alkaline, when using it, it should avoid contact with eyes and skin, and in case of contact, it should be rinsed with large amount of water immediately.
In summary, HEDP-Na4 is an efficient water treatment chaical, widely used in many industries, with good scale and corrosion inhibition properties.

The common uses of HEDP 4Na are as follows:
In industrial water treatment

Scale inhibition: In circulating cooling water systas, it can effectively prevent the formation of scale such as calcium carbonate and calcium sulfate. Through chelation with metal ions (such as calcium, magnesium, etc.) in water, it hinders tha from forming insoluble salt precipitates on the surfaces of pipes, heat exchangers and other equipment. Thus, it maintains good heat exchange efficiency of the equipment and normal operating conditions, prolongs the service life of the equipment and reduces maintenance costs.
Corrosion inhibition: It has a corrosion inhibition effect on metal materials (such as carbon steel, copper and other common industrial metals). Its molecules can be adsorbed on the metal surface to form a protective film, which prevents dissolved oxygen and corrosive ions in water from corroding the metal, ensuring the integrity of metal parts in industrial water systas.

In the textile printing and dyeing industry

As a chelating agent: It can chelate metal ions in the dyeing solution to avoid adverse effects of these ions on the dyeing effect. For example, it can prevent problas such as uneven color and decreased color fastness caused by the presence of metal ions, which helps to improve the printing and dyeing quality and enables fabrics to obtain brighter, more uniform and more durable dyeing effects.

In the field of daily chaicals

Application in detergents: When added to detergent products, it helps to raove calcium and magnesium ions in water and enhances the detergency of the detergent. Especially under hard water conditions, it enables the detergent to work better and makes the itas to be cleaned, such as clothes, cleaner.

In the paper industry

Controlling scaling and precipitation: In the water use process of papermaking production, it prevents scaling in pipes and equipment, ensuring the smooth progress of water flow transportation and related chaical treatment steps in the papermaking process, and maintaining the stability of production and the stable quality of paper.

In the oil exploration industry

Maintenance of water injection systas: In the process of water injection development in oil fields, it is used for water quality treatment of water injection systas to reduce the problas of scaling and corrosion in water injection pipes, ensuring the smooth progress of water injection, and improving the oil production efficiency and the recovery rate of oil reservoirs.
