Sell HEDP Scale and corrosion Inhibitor

Description

HEDP is an organophosphoric ***** can be chelated with Ca2 、Zn2 ions to form stable chelating compounds. It shows excellent antiscale and corrosion inhibition effects. HEDP has good chemical stability under high temperature and high PH value. It is hard to be hydrolyzed. HEDP can be reacted with Ca2 、Zn2 in water system to form chelating complex film on metal equipment surfaces. Therefore HEDP has good corrosion inhibition. 4.Application: HEDP is used as scale and corrosion inhibitor in circulating cool water system, oil field and low-pressured boilers in fields, such as power plant, chemical and metallugy industry, etc. 5.Specification: (1).Appearance:Colorless or light yellow transparent liquid (2).Active content(%):≥*0 (3).PH(1% Solution):≤2 (4).Density(*0℃)g/cm3:≥1.*4 (5).Phosphorous acid (as )%:≤2 (6).Phosphoric acid (as )%:≤0.8
