Application

Ethylenediaminetetraacetic acid tetrasodium(EDTA-4Na) is a multifunctional chelating agent widely used in various fields of industrial production:
Water treatment:
As a water softener, EDTA-4Na can chelate hardness ions such as calcium and magnesium, prevent scale formation, and improve water quality. In boiler descaling, its chelating ability can reduce scale deposition, improve thermal efficiency, and its stability at high temperatures is better than traditional phosphates. ‌
Textile and printing and dyeing:
EDTA-4Na is used as a dyeing aid to eliminate the interference of metal ions on dyes, improve dyeing uniformity and color fastness. In acrylic fiber processing, as an initiator, it can improve fiber whiteness and strength. ‌
Daily chemical industry:
EDTA-4Na enhances the cleaning ability of surfactants in detergents and prevents component failure caused by metal ion catalytic oxidation. Hard surface cleaners reduce water residue by chelating metal impurities. ‌
Pharmaceutical industry:
EDTA-4Na can be used to treat heavy metal poisoning (such as lead and mercury) and promote toxin excretion; Relieve hypercalcemia and reduce calcification deposition. ‌
Food industry:
EDTA-4Na can prevent metal ions from oxidizing food ingredients and extend shelf life. Used to stabilize calcium ions in infant food and dairy products, avoiding protein precipitation. ‌
Rubber and plastic:
During the polymerization of styrene butadiene rubber, EDTA-4Na is used as an activator to enhance the uniformity of molecular weight distribution; Chelate metal impurities in PVC processing to prevent catalytic oxidation. ‌
Paper and printing:
EDTA-4Na can improve the water resistance of paper and enhance bleaching efficiency; Stable sizing agent to reduce metal ion interference.
