ATMP can be replaced by HEDP? What is its advantages?

                                                   ATMP can be replaced by HEDP? What is its advantages?

ATMP (aminotris(methylenephosphonic acid)) and HEDP (hydroxyethylidene diphosphonic acid) are both commonly used corrosion and scale inhibitors. While they can replace each other to a certain extent, they also have their own characteristics and applicable areas.

HEDP can partially replace ATMP, depending on the specific application scenario and needs. The following are some advantages of HEDP over ATMP:

1. Good heat resistance: HEDP is more stable under high temperature conditions, making it more suitable for use in high-temperature environments than ATMP.

2. Good metal compatibility: HEDP is compatible with a variety of metals, including iron, copper, and aluminum, while ATMP can be highly corrosive to metals in some cases.

3. Adaptability to water quality: HEDP is more stable under varying water conditions, has a wider range of water quality adaptability, and has a wider range of applications.

In summary, HEDP has certain advantages in heat resistance, metal compatibility and water adaptability, and can replace ATMP to a certain extent, but the specific choice still needs to be determined according to actual usage needs and circumstances.
