DTPMP•Na₂ (Sodium Salt of Diethylene Triamine Penta (Methylene Phosphonic Acid) ) is a versatile chelating agent and scale inhibitor commonly used in water treatment, detergents, and industrial applications.
The usage ratio of DTPMP•Na₂ largely depends on the specific application, as it varies by industry and purpose. Here are a few general examples of how it’s typically used:
-
Water Treatment:
- In cooling water systems, the dosage of DTPMP•Na₂ is generally around 10 to 50 ppm (parts per million), depending on the hardness of the water and the specific scale control requirements.
- For boiler water treatment, the dosage is often in the range of 1 to 5 ppm.
-
Detergents:
- In laundry and dishwashing detergents, the concentration can vary from 0.1% to 1% by weight, depending on the formulation and the level of hardness of the water used.
-
Industrial Applications:
- For applications such as oilfield treatments or other industrial processes, the usage ratio can range from 0.5 to 5% depending on the severity of scale formation and the conditions.
