  4.4 Chemical Synthesis and Electroplating Industry

  • As an intermediate in chemical synthesis, it is used in the production of chemical products such as sodium gluconate, calcium gluconate, and sorbitol, and serves as a basic raw material in fine chemicals and organic synthesis.
  • 
    
  • In the electroplating industry, it is used as an additive in electroplating solutions. Utilizing its reducing and chelating properties, it complexes metal ions in the electroplating solution, improves the uniformity, gloss, and adhesion of the electroplating layer, enhances the effect of the electroplating process, and prevents the precipitation of metal ions.
  • 
    
  • Used as an industrial cleaning aid, it is used in conjunction with other cleaning agents to soften water quality, chelate calcium and magnesium ions in water, enhance cleaning effects, and is suitable for cleaning industrial equipment and pipelines
  • 
    
  • 

  4.5 Textile Dyeing and Printing and Other Industrial Scenarios

  • In the textile dyeing and printing industry, it is used as a dyeing and printing auxiliary. It adjusts the pH value of the dyeing and printing solution, improves the dye uptake rate and levelness of the dye, enhances the color of fabrics, and reduces problems such as dyeing spots and color differences.
