Superiority

the hedp.na2 has two forms: liquid and powder.
the powder is 90% min;the liquid is 20% min.
it is stable under high ph value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition, its acid or alkaline and chloride oxidation tolerance are better than that of other organophosph-onic acids. hedp.na2 can form six-ring chelating compounds with metal ions in water system, ca2+ in particular. hedp.na2 has good scale inhibition effects and obvious dissolution threshold effects. when used with other water treatment chemicals, the synergistic effects is better.
twin chemical co.,ltd. is a modern enterprise for production,sale,export and trade of chemicals.
