What is KR-445
HEDP•Na4, the sodium salt of Hydroxyethylidene Diphosphonic Acid (HEDP), is a highly effective scale and corrosion inhibitor used across a variety of industrial applications. Here’s a detailed overview of its properties and uses:
- Scale Inhibition: HEDP•Na4 is particularly effective as a scale inhibitor for calcium carbonate, preventing its deposition in various water systems.
- Applications:
- Low Pressure Boiler Water Systems: It is used to prevent scale formation in boiler water, which can reduce efficiency and cause operational issues.
- Circulating Water Systems: HEDP•Na4 helps maintain the clarity and efficiency of water in circulation systems by inhibiting scale buildup.
- Industrial and Municipal Cleaning Water Systems: It is used to prevent scale in water systems used for cleaning purposes in both industrial and municipal settings.
- Swimming Pools: HEDP4Na can be used in swimming pools to prevent scale formation on pool surfaces and equipment.
- Physical Form: The solid form of HEDP•Na4 is a white powder that is soluble in water.
- Deliquescent Property: It is easily deliquescent, which means it can absorb moisture from the air. This property makes it suitable for use in environments where humidity is high, such as winter and freezing districts.
- Chemical Nature: As an organophosphonic acid scale and corrosion inhibitor, HEDP•Na4 can form stable complexes with metal ions like iron (Fe), copper (Cu), and zinc (Zn).
- Corrosion Inhibition: It can dissolve oxides on metal surfaces, providing protection against corrosion.
- Temperature Stability: HEDP•Na4 has good scale and corrosion inhibition effects up to temperatures of 250°C, making it suitable for high-temperature applications.
- Widespread Use:
- Circulating Cool Water Systems: It is widely used in these systems to prevent scale and corrosion.
- Medium and Low Pressure Boilers: HEDP•Na4 is used in boiler systems to maintain efficiency and protect against scale and corrosion.
- Oil Field Water Pipelines: It serves as a scale and corrosion inhibitor in oil field operations.
- Industrial Fields: HEDP•Na4 is used in various industries such as electric power, chemical, metallurgy, and fertilizer production.
- Light Woven Industry: In this industry, HEDP•Na4 is used as a detergent for both metal and nonmetal surfaces.
- Dyeing Industry: It functions as a peroxide stabilizer to prevent the breakdown of bleaching agents and as a dye-fixing agent to improve dye adherence to fabrics.
- Non-Cyanide Electroplating: HEDP•Na4 is used as a chelating agent in electroplating processes that do not use cyanide, helping to bind and remove metal ions.
HEDP•Na4’s versatility, effectiveness, and stability make it a valuable compound in industrial water treatment and other applications where scale and corrosion control are essential.
