HEDP•Na4

High quality of Tetra Sodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP·Na4)from China at HANGZHOU TONGGE ENERGY TECHNOLOGY CO., LTD. Tetra Sodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP·Na4) it is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good dispersant performance against carbonate and scale inhibition for phosphate. it has good thermal stability, can be used under high temperature (300℃). Copolymer of Maleic and Acrylic Acid has good compatibility when used together with other agents. Copolymer of Maleic and Acrylic Acid is widely used in low-pressure boiler, centralized heating, centralized air-conditioner and circulating cool system. It can also be used as chelating dispersants in woven and dyeing fields.

Specifications of the Tetra Sodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP·Na4):

Application: Tetra Sodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP·Na4)It is an excellent inhibitor of calcium carbonate scale, HEDP•Na4 is mainly used for low-pressure boiler water treatment, circulating water treatment, industrial municipal clean water, and metal corrosion inhibition of swimming pool sterilization. HEDP•Na4 is a white powder solid, soluble in water, non-moisture absorption, easy to transport, suitable for use in cold conditions. HEDP•Na4 is an organic phosphonate scale inhibitor and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve oxides on the metal surface. It still has good corrosion inhibition and scale inhibition effect at 250℃. HEDP•Na4 is widely used in electric power, chemical industry, metallurgy and chemical industry.

Packing: 25kg/bag, 1000kg/bag.
