Tetrasodiumof1hydroxyethylidene-1.1-diphosphonicacid(hedpna4) with CAS 3794-83-0

(1-Hydroxyethylidene)bis-phosphonic Acid Tetrasodium Salt is used in method for applying a gel compound on a surface of a device and corresponding coated device.

Industrial circulating cooling water, low-pressure boiler water: Prevent calcium carbonate and calcium sulfate scaling, protect carbon steel and copper equipment, reduce metal corrosion.
Oilfield reinjection water, oil pipeline: Scale inhibition, metal corrosion inhibition, inhibit pipeline oxidation corrosion.
Textile printing and dyeing: Peroxide stabilizer, color fixative; Metal/non-metal cleaning agent.
Cyanide-free electroplating: Metal complexing agent.
Pool, municipal industrial cleaning water: Metal corrosion inhibition, scale inhibition.
Daily chemical additives.

Key selling points:

1. Excellent high-temperature stability, maintaining good scale inhibition and corrosion prevention effects even at 250℃, suitable for boilers and high-temperature circulating water conditions.
2. Outstanding inhibition effect on calcium carbonate scale, capable of complexing various metal ions such as iron, copper, and zinc, dissolving the oxide layer on metal surfaces, providing both scale inhibition and corrosion prevention functions.
3. Excellent water solubility for the solid version, with solid powder not prone to freezing, suitable for use in cold regions; the liquid version can be directly measured and added, with flexible selection options.
4. Excellent compatibility, can be compounded with most organic phosphates and polyacrylate water treatment agents, widely used in the production of compound scale inhibitors.
5. Universal across multiple industries: water treatment, textile printing and dyeing, cyan-free electroplating, metal cleaning, applicable to multiple scenarios in various industries.
6. Long-lasting stability, low dosage takes effect, does not easily develop resistance quickly, suitable for continuous circulating water systems.
