60% 1-hydroxy ethylidene-1,1-diphosphonic acid as scale and corrosion inhibition hedp

hydroxy ethylidene-1,1-diphosphonic acid (hedp)

cas no. 2809-21-4

molecular formula: c2h8o7p2 molecular weight: 206.02

hs no: 2931900090

un no. 3265

properties:

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℃.

usage:

hedp is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. in light woven industry, hedp is used as detergent for metal and nonmetal. in dyeing industry, hedp is used as peroxide stabilizer and dye-fixing agent; in non-cyanide electroplating, hedp is used as chelating agent.

package: 200l plastic drum, ibc(1000l), and as customers’ requirement.
