Name: HEDP
CAS: 2809-21-4
Chemical formula: C2h8o7p2
Appearance: Colorless transparent liquid
Etidronic acid (HEDP) is a new type of chloride free electroplating complexing agent, which is used as the main agent to stabilize the water quality in the circulating cooling water system and plays a role of corrosion and scale inhibition.
This product is one of the organic polyphosphonic acid free water tablets, and there are also other varieties of this type of product produced domestically, such as amino trimethylene phosphonic acid (ATMP): [CH2PO (OH) 2] 3N, and (EDTMP), etc. Organic polyphosphonic acid is a type of water treatment agent developed in the late 1960s and confirmed around the 1970s. The emergence of this type of treatment agent has taken a significant step forward in water slicing technology. Compared with organic polyphosphates, organic polyphosphonate free acids have the characteristics of chemical stability, difficult hydrolysis, high temperature resistance, small dosage, and scale moderation. It is a type of cathodic corrosion inhibitor and a type of non chemical equivalent scale inhibitor; When used in combination with other water treatment agents, it exhibits ideal synergistic effects. It has excellent chelating properties for many metal ions such as calcium, magnesium, copper, zinc, etc., and even has good deactivation effects on inorganic salts of these metals such as CaSO4, CaCO3, MgSiO3, etc. Therefore, it is widely used in water treatment technology.

HEDP.Na2 is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP.Na2 is used as detergent for metal and nonmetal. In dyeing industry, The dyes the industry fixing agent In non-cyanide electroplating used as chelating agent.
HEDP-Na2, full name Hydroxyethylidene Diphosphonic Acid Sodium Salt (HEDP-Na2), is a commonly used water treatment agent, which is widely used in many fields. The uses of HEDP-Na2 can be summarized as follows:
Ⅰ. Water treatment and industrial applications
1. scale inhibitor:
*HEDP-Na2 can effectively prevent minerals in water (such as calcium and magnesium) from forming scale on pipelines, boilers, cooling towers and other equipment, keeping the equipment in normal operation and reducing maintenance and energy consumption.
*It can form stable complexes with metal ions (especially calcium ions) in water and has excellent scale inhibition effect.
2. Corrosion inhibitor:
*HEDP-Na2 can form a protective film on the metal surface to avoid corrosion and oxidation of metal in water and extend the service life of equipment.
*It can form coordination complexes with metal ions, effectively inhibiting metal corrosion.
3. Cleaning agent:
*HEDP-Na2 can dissolve hardness ions and metal ions in water, inhibit the generation of scale and scale marks, and remove deposits in pipelines.
*It also has a certain removal effect on the already formed scale layer.
4. chelating agent:
*It can combine with metal ions in water (e.g. iron, copper, etc.) to form soluble complexes, preventing these metal ions from being deposited down, thus reducing corrosion and scaling problems in water treatment systems.
5. Hardness stabilizer:
*HEDP-Na2 can control the hardness ions in the water, prevent scale formation and keep the water quality stable.
Ⅱ. Application in industrial field
HEDP-Na2 is widely used in industrial production in cooling water systems, hot water boilers, oil extraction, electroplating, pulp and paper and other fields. Specifically:
* In electric power, chemical industry, metallurgy, fertilizer and other industries, it is commonly used in circulating cooling water system scale inhibition and corrosion inhibition.
*HEDP-Na2 also plays an important role in the treatment of oilfield water injection and oil pipeline.
*In the light textile industry, it can be used as metal and non-metal cleaning agent.
*In the bleaching and dyeing industry, it can be used as a peroxide stabilizer and color-fixing agent.
*In cyanide-free electroplating industry, it is an important complexing agent.
III. Household application
In family life, HEDP-Na2 can be used in the maintenance and cleaning of household water appliances, such as washing machines, baths, faucets, etc., to help remove scale and sediments and keep the equipment running well.
IV. Precautions for use
*Although HEDP-Na2 is generally of low toxicity to humans, it is still necessary to follow safe operating procedures when using it and avoid direct contact with skin and eyes.
*When discharging or disposing, relevant environmental regulations should be followed to avoid negative impact on the environment.
In summary, HEDP-Na2 plays an important role in water treatment and industrial applications, with scale inhibition, corrosion inhibition, cleaning, chelation and other functions, it is an important chemical for maintaining equipment and improving water quality.
HEDP.Na2 plastic drum, 25kg or 250kg, or confirmed by clients Storage for ten months in shady room and dry place.
HEDP.Na2 Weak acidity, Avoid contact with eye and skin, once contacted, flush with water.
