Product Overview
HEDP 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. HEDP shows excellent scale and corrosion inhibition effects under temperature 250°C. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals. .

HEDP shows excellent scale and corrosion inhibition effects under temperature 250. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.

Effect
A. Water retention---Improved water retenton can protect cement and plaster against poor solidification and cracking due to too speedy drying and inefficient mixing with water.
B.Workability---Mortar plasticizing quality can be improved, which in turn will improve the workability of painting and working efficiency.
C.Binding---Due to the increased plasticizing quality, mortar can be a better binder.
D.Slipping-resistance---Due to the thinckening action of Cellulose Ether, the slipping phenomena of mortar from substance to be bound can be prevented more efficiently.

Note

1.Highest viscosity shall be obtained by completely mixing or agitating both before and after the addition of the product.
2.Direct addition of the product with surface treatment into alkaline water solution will lead to the failure of the surface treatment, resulting in gel. Therefore, product with surface treatment can not be added into the alkaline water solution directly.
3.Tht concerntration of the prepared solution shall be determined according to the product viscosity. The solution concentration of product with low viscosity(lower than 100mPa.s)is 10~15%,and the solution concentration of product with high viscosity(more than 30000mPa.s)is 2-3% at most.
