1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) is an organophosphoric acid compound supplied by Zao Zhuang Xin Tai Water Treatment Technology Co., Ltd. from Shandong, China. This corrosion inhibitor works by chelating with iron, copper, and zinc ions to form stable compounds, effectively dissolving oxidised materials from metal surfaces. It maintains strong scale and corrosion inhibition performance at temperatures up to 250°C and demonstrates good chemical stability under high pH conditions, resisting hydrolysis and decomposition under ordinary light and heat.
HEDP forms a hexa-element chelating complex with metal ions in water systems, particularly calcium ions, providing visible threshold antiscale effects. When combined with other water treatment chemicals, it delivers synergistic performance. The solid form is a crystal powder suited to cold-climate applications, while its high purity also makes it suitable as a cleaning agent in electronics and as an additive in daily chemical products. Key applications include circulating cooling water systems, oil fields, low-pressure boilers across power, chemical, metallurgy, and fertiliser industries. It also serves as a metal and non-metal detergent in light weaving, a peroxide stabiliser and dye-fixing agent in dyeing, and a chelating agent in non-cyanide electroplating.
Zao Zhuang Xin Tai supplies HEDP liquid in 250 kg net plastic drums (IBC drums available on request) and HEDP solid in 25 kg packages with an inner polyethylene bag and outer plastic woven bag. Specific packaging, minimum order quantities, and pricing should be confirmed directly with the supplier.
