Applications
  • 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.
  • It can form a protective film on the surface of iron, lead, zinc, 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 keeps solution pH value unchanged for a long time.
  • It is widely used for surface treatment, paint and coating, detergent, boiler antiscaling, food additive, oil well drilling, textile dye printing ancillary, and others.
