1 Pure EDTA 4NA is an important kind of complexing agent.EDTA USES is very wide, can be used for bleaching of color photographic materials washing
processing fixing bath, dyeing auxiliaries, fiber processing additives, cosmetic additives, blood anticoagulant, detergent, stabilizing agent, synthetic rubber
polymerization initiator, Pure EDTA 2NA chelating agent is the representation of the material.Can and alkali metals, transition metal and rare earth elements
to form stable water-soluble complex.In addition to sodium salt, ammonium salt and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc.
Various kinds of salt, the salt have different purposes.MoreoverPure EDTA 2NA can also be used to make rapid excretion from the human body harmful radioactive
metal detoxification effect.Is the water treatment agent.Pure EDTA 2NA is an important indicator, but used to titrate metal nickel, copper, etc., and use it every time
you want to use with ammonia, can act as indicator.
2, Pure EDTA 4NA is a good calcium and magnesium ion chelating agent, used as a water by emulsion polymerization chela agent and remove Ca2 +, magnesium
2 +, Fe2 + and Fe3 + and other metal ions.Also used as the complexing agent of anaerobic adhesive, double methacrylate with Pure EDTA 2NA treatment, removal
of transition metal ions, eliminate the influence of can promote the compound peroxide decomposition and to improve the stability of the anaerobic adhesive effect is
very good.Pure EDTA 2NA sodium salt chelating metal ion can improve modified acrylic quickly.Solid structural adhesive (SGA) storage stability, dosage of 10-4-3 x
to 6.0 x 10-4.Dosage of 1.5%, more than 50 ~ C storage stability of 360 h (50 ℃ storage 4 d, equivalent to SGA20 ~ C store 1 year).
