Six Core Advantages
- Super chelation: Can simultaneously complex metal ions such as Ca²⁺, Mg²⁺, and Fe³⁺, with a scale inhibition rate of over 95%
- Industrial-grade purity: According to the HG/T2519-2017 standard, the content of P₂O₅ is ≥68% and the water-insoluble matter is ≤0.08%
- Applicable to multiple scenarios: Suitable for 8 major industrial fields including water treatment, metal processing and building materials
- Compound combination enhances efficacy: When used with water treatment agents such as HEDP and PAA, the effect is enhanced by 30%
- Cost optimization: Dosage is only 5-20 PPM, reducing the cost per ton of water treatment by 40%
- Safety and environmental protection: Contains no heavy metals (Pb < 5ppm) and has passed REACH certification
