1. Adsorption stability theory:
The high-molecular micelles adsorb heavy metal ions through static electricity or hydrogen bonds to achieve the purpose of stability.
The types of stabilizers include: water glass, fatty acid magnesium, polyacrylamide partial hydrolysate, polycarboxylate, etc.
2. Complexation stability theory:
A stable water-soluble complex is formed by chelating the sequestrant with the metal ion, thereby preventing the heavy metal from catalyzing.
Such stabilizers include phosphates, amino carboxylates, alcohol amines, hydroxy carboxylates and phosphates.
