Product Description

Properties of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:
HEDP (Cas No 2809-21-4) Corrosion Inhibitor is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals' surfaces. 

Package and Storage of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:
HEDP (Cas No 2809-21-4) Corrosion Inhibitor: Normally in 250kg net Plastic Drum, IBC Drum can also be used as required.

Storage for ten months in shady room  and dry place. 

 

Using Method:

 

1. Construction projects: The transportation of water in construction projects is essential, including building foundation drainage pipes, household water or sewage discharge pipes, and other parts of the building that need to be used in some drainage or water supply systems.
2. Civil engineering and public works: This aspect is relatively wide. Due to the anti-corrosion, wear resistance and environmental protection of HDPE pipes, it is often used for water supply. In addition, it has the unique electrical insulation properties of plastic, so it can also be used for protective tubes such as power tubes and telecommunication tubes. It can be used for drainage pipes in sewers, hillsides, railways, highways, bridges, tunnels, etc.
3. Agricultural engineering: There are many places where water is needed in agricultural engineering. The growth of vegetation is inseparable from water irrigation. Of course, it is also necessary to prevent the vegetation from being submerged when heavy rains hit. Therefore, pipes are also widely used in farmland drainage pipes, crop irrigation pipes, etc.
