Detailed Description

Cas No.: 13845-36-8 Specification: 95% min and RoHS compliant Appearance:White powder Purity%:85.0min pH:9.2-10.3 Pb mg/kg:5 max As mg/kg:3 max Fluoride mg/kg:10 max Insoluble Substances %:2.0 max Loss on Dry %:0.5 max Package:25kg Product Characteristics: It has excellent chelating ability and can form stable chelates with Ca2+ and Mg2+ in hard water so as to soften hard water, increase cleaning ability, and remove dirt. The white precipitate formed from adding 13mL of 1% calcium nitrate solution into 100 mL of 1% potassium pyrophosphate solution can be rapidly chelated to produce a clear solution. It can form a protective film on the surface of iron, lead, zine, and other metals so as to prevent surface corroding. P2O74- has a strong dispersion ability to disperse finely distributed solid particles so that these fine and trace materials can mix evenly. It has stable pH buffering ability and keep solution pH value unchanged for a long time. It is easy to dissolve in water with solubility of 178 g, 194 g, and 212 g in 100 mL of water at 10 C, 25C, and 50C respectively. Major Application: It is widely used for surface treatment, paint and coating, detergent, boiler antiscaling, food additive, oil well drilling, textile dye printing ancillary, and others
