HEDP 4Na has a similar effect to HEDP 2Na and is commonly used as a chemical in water treatment, scale inhibitor, and corrosion inhibitor. It can react with calcium and magnesium plasma to inhibit the formation of hard water ions such as calcium and magnesium, and prevent scale from adhering to the surface of equipment, pipelines, and other materials; At the same time, it can also form a protective film on the metal surface, thereby reducing the corrosion and oxidation reactions of the metal and achieving a corrosion inhibition effect.

What is the use of HEDP Na4?

• Scale inhibitor: HEDP 4Na can form complexes with metal ions such as calcium and magnesium in water, preventing the crystallization of hard water ions and the formation of scale, thereby preventing the accumulation and blockage of scale on the surface of equipment, pipelines, etc.
  

• Corrosion inhibitor: HEDP 4Na can react with metal surfaces to form a protective film, reducing corrosion and oxidation reactions of metals, and improving the durability and service life of metal materials.
  

• Dispersant: HEDP 4Na has strong dispersion ability, which can suspend solid particles in water to avoid sedimentation and accumulation, and maintain clean water quality.
  

• PH buffer: HEDP 4Na has a buffering effect, which can stabilize the pH value of water and prevent the impact of acid-base reactions on water quality and equipment.
