1. Performance and Applications

DTPMP·Na7 (Diethylene Triamine Penta(methylene Phosphonic Acid) Heptasodium) is a multifunctional organic phosphonic acid salt with the following main applications:

Scale Inhibitor: E​ffectively prevents the formation of scale such as carbonates and sulfates in water, widely used in cooling water treatment, oil field scale inhibition, and geothermal water treatment.

Efficient Chelating Agent: Forms stable complexes with various metal ions, suitable for removing heavy metal ions from water, such as lead, cadmium, and chromium, to improve water quality.

BaSO₄ Scale Inhibitor: Particularly effective in preventing the formation of barium sulfate scale.

Stabilizer for Peroxide Bleaching: In the textile dyeing and printing industry, it is used as a chelating agent and pigment dispersant to enhance the dyeing effect and product quality.

Detergent Adjuvant: Enhances cleaning effectiveness and improves cleanliness.

Municipal and Industrial Cleaning Water: Improves water quality and prevents the accumulation of scale.

Fertilizer Industry: Used as a micronutrient carrier to improve fertilizer efficiency and utilization.

Other Fields: Also used in papermaking, electroplating, metal pickling, and cosmetics industries.
