Sinobio
29319090
CAS NO. 7414-83-7
Molecular Formula: C2H6O7P2Na2
Molecular weight: 250
Hydroxyethylenediphosphonic acid (HEDP) is a new type of chlorine-free electroplating complexing agent, which is used as the main agent for water quality stability in circulating cooling water system and plays the role of corrosion inhibition and scale inhibition.
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 is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions, it can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250ºC,it is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition, its acid/alkaline and chloride oxidation tolerance are better than that of other organophosph- onic acids. HEDP.Na2 can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP.Na2 has good scale inhibition effects and obvious dissolution threshold effects. When usedwith other Water Treatment Chemicals, the synergistic effects is better.
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.

*Cleaning agent: HEDP-Na2 can dissolve hardness ions and metal ions in the water, inhibit the generation of scale and scale marks, and also remove deposits in the pipeline to keep the water quality clean.
*Inhibit the growth of bacteria and algae: HEDP-Na2 also has the function of inhibiting the growth of algae and bacteria in the water, which helps to prevent the pollution of water quality and the generation of odor.
2. Light Textile Industry
*Cleaning agent: In the light textile industry, HEDP-Na2 can be used as a cleaning agent for metal and non-metal, effectively removing all kinds of stains and impurities, making products cleaner and more beautiful.
*Bleaching and dyeing auxiliaries: In bleaching and dyeing industry, HEDP-Na2 can be used as peroxide stabilizer and color-fixing agent, which can improve the quality of the products and the stability of the color.
3. Electroplating industry
*Complexing agent: In cyanide-free plating industry, HEDP-Na2 can be used as complexing agent to improve the stability and durability of plating layer.
4. Other fields
*Petrochemical: HEDP-Na2 can be used as an oilfield water injection agent to prevent scale and corrosion formed during water injection and protect the normal operation of oilfield equipment. Meanwhile, it can also be used as an additive of drilling fluid to improve drilling efficiency.
*Paint and pigment: HEDP-Na2 can be used as a dispersant for paint and pigment to improve the dispersibility of pigment in paint and make the paint have better color and luster.
*Rubber and plastics: HEDP-Na2 can be used as a stabilizer for rubber and plastics, preventing oxidation and aging of rubber and plastics during processing and use, and improving the durability of rubber and plastics.
5. Household life
*HEDP-Na2 can also be used for the maintenance and cleaning of household water appliances such as washing machines, bathtubs, faucets, etc. in family life, helping to keep household equipment in good operating condition.
In summary, HEDP-Na2 plays an important role in many fields by virtue of its excellent performance, and it is a kind of efficient and environmentally friendly chemical reagent. With the continuous progress of science and technology and the expansion of application fields, the application prospect of HEDP-Na2 will be more broad.
