Usage
Agricultural Micronutrient Fertilizers:
Used as a raw material in the production of chelated iron fertilizers to prevent “yellow leaf disease” in plants caused by iron deficiency. Performs exceptionally well in alkaline soils.
Industrial Cleaning and Descaling:
Used for chemical cleaning of boilers, heat exchangers, and high-pressure pipelines, efficiently removing iron, copper, and calcium/magnesium scale without damaging the metal substrate.
Textile Printing and Dyeing:
Used as a stabilizer in bleaching processes to chelate trace transition metals in water, preventing fabric tears or uneven whiteness.
Daily Chemicals:
Added to high-grade detergents, soaps, and personal care products to eliminate the influence of hard water ions on the foaming power of surfactants and prevent product rancidity and discoloration.
Oilfield Chemicals:
Used as an iron ion stabilizer in oil extraction processes to prevent precipitation and formation blockage.
Pulp Bleaching:
Used in the mechanical or chemical pulp bleaching of the paper industry to prevent heavy metal ions from catalytically destroying the bleaching agent.
