Application:
1. EDTA is an important complexing agent. EDTA has a wide range of uses. It can be used as a bleaching and fixing solution for the processing of color photosensitive materials, dyeing aids, fiber processing aids, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiators, and EDTA is a chelating agent. The representative substance of the mixture. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals.
2. Ethylenediaminetetraacetic acid is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water used in emulsion polymerization to remove Ca2+, Mg2+, Fe2+, Fe3+ and other metal ions. It is also used as a complexing agent for anaerobic adhesives, that is, EDTA is used to treat methacrylic acid diester to remove transition metal ions, eliminate the effect of promoting peroxide decomposition, and have a very good effect on improving the stability of anaerobic adhesives. EDTA sodium salt chelating metal ions can improve the modification speed of acrylic acid.
3. It is often used to soften boiler water quality. Prevent scaling
