Application

1, EDTA is an important complexing agent. EDTA is widely used as bleaching fixative, dyeing auxiliaries, fiber treatment auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiator, EDTA is a representative chelating agent. It can form stable water soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are ammonium salt and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, these salts have different uses. In addition, EDTA can also be used to detoxify harmful radioactive metals from human body. It is also a water treatment agent. EDTA is also an important indicator, but used to titrate nickel, copper, etc.
2. EDTA is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water emulsion polymerization to remove metal ions such as Ca2+, Mg2+, Fe2+ and Fe3+. It can also be used as a complexing agent for anaerobic adhesives, that is, EDTA is used to treat dimethyl methacrylate to remove transition metal ions and to eliminate the effect of promoting the decomposition of peroxides, which is very good for improving the stability of anaerobic adhesives. EDTA sodium chelate metal ions can improve the speed of modified . The storage stability of solid structural adhesive (SGA) is -3 * 10-4 to 6 * 10-4. The storage stability of 50~C was more than 360h at 1.5%, and stored at 50 C for 4D, equivalent to SGA20~C storage for 1 years.
3, commonly used in boiler water softening. Prevent scaling.
