use
1. Ethylenediaminetetraacetic acid (EDTA) is an important complexing agent. EDTA is widely used as a bleaching fixer, a dyeing auxiliary, a fiber treatment auxiliary, a cosmetic additive, a blood anticoagulant, a detergent, a stabilizer, and a polymerization initiator for synthetic rubber. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt, and aluminum, each of which has different uses. In addition, EDTA can also be used to rapidly excrete harmful radioactive metals from the human body and play a detoxifying role. It is also a water treatment agent. EDTA is also an important indicator, but it is used to titrate metal nickel, copper, etc., and it must be used with ammonia to play the role of an indicator.
2. Ethylenediaminetetraacetic acid is an excellent chelating agent for calcium and magnesium ions, which is used as a chelating agent for emulsion polymerization to remove metal ions such as Ca2+, Mg2+, Fe2+, and Fe3+. It is also used as a complexing agent for anaerobic adhesives, that is, dimethyl methacrylate is treated with EDTA to remove transition metal ions and eliminate the influence that can promote peroxide decomposition, which has a very good effect on improving the stability of anaerobic adhesive. EDTA sodium salt chelates metal ions to improve the speed of modified acrylic acid. Storage stability of solid structure adhesive (SGA), dosage -3×10-4~6.0×10-4. Dosage 1.5%, storage stability at 50~C for more than 360h (storage at 50°C for 4d, equivalent to SGA20~C storage for 1 year)
3. It is often used for softening boiler water quality. Prevents fouling.
