Core Performance Advantages

1. Highly Effective Scale Inhibition:

- Scale inhibition rate reaches 98% against calcium carbonate and calcium phosphate scale (at a dosage of 5-15 mg/L).

- Maintains stable scale inhibition even under high temperatures (below 120°C), high hardness, and high alkalinity.

- Can increase circulating water concentration to over 7 times, reducing water waste.

2. Excellent Corrosion Inhibition:

- As an excellent stabilizer for zinc salts, it stabilizes zinc ions at pH 7.0-9.5, enabling alkaline operation of zinc-containing formulations.

- Forms a protective film on metal surfaces, reducing corrosion rates and extending equipment life.

3. Oxidation and Chlorine Resistance:

- Excellent resistance to chlorine oxidation, suitable for chlorine-containing water treatment systems.

- Resists hydrolysis at pH > 14, demonstrating strong adaptability.

4. Low Phosphorus Environmental Protection:

- Low phosphorus content meets environmental requirements and reduces the risk of eutrophication.
