Product use:
This product can quickly form water-soluble complexes with metal ions such as calcium, magnesium, iron, lead, copper, and manganese, especially with high-valent color-forming metal ions. Therefore, it is widely used in
① hydrogen peroxide bleaching synergist stabilizer ② water softener ③ textile printing and dyeing industry auxiliaries
④ color photosensitive material processing bleaching fixer ⑤ analytical chemistry reference reagent
⑥ chelating titrant ⑦ daily chemical industry ⑧ cosmetics industry
Paper: Mainly used in pulp bleaching and decolorization. Usually used as a bleaching stabilizer for hydrogen peroxide, it has obvious synergistic and stabilizing effects: In addition, this product also has a strong complexing (chelating) effect on multivalent color-forming metal ions, turning the color-forming metal ions into colorless water-soluble complexes to improve the whiteness of the pulp. It is usually used in the waste paper deinking process. It is added together with the deinking agent during pulping. The amount per ton of dry waste paper is generally 1-2 kg.
Textile printing and dyeing: This product eliminates the effect of multivalent ions on the color of dyes in the system through complexation (chelation) to avoid color deviation and color stability, and meet the application requirements of printing and dyeing. It is generally added during water treatment to complex the metal ions in the water system to avoid the effect of metal ions on dyes. The amount used depends on the type and content of metal ions in the system, and the specific amount should be based on experimental results.
