What Factors Affect The Viscosity Of Polyaluminium Chloride?

Currently, apart from polyaluminium chloride, there are no other substances that can achieve a better flocculation effect, mainly because it has a good viscosity in water. The viscosity of polyaluminium chloride is related to its aluminium oxide content and relative density, which is an indicator of the effective components. The greater the density of the product, the higher its aluminium oxide content, and as the aluminium oxide content increases, its viscosity will also increase. The factors affecting viscosity mainly include the following:

1. Molecular form: The form of polyaluminium chloride dissolved in water can particularly affect the viscosity of the treatment; generally, long chains have a greater viscosity than short chains.
2. Molecular weight: The molecular weight here refers to the weight of 1 mol of the chemical agent; the greater the molecular weight, the higher the relative viscosity.
3. Charge density: We all know that chemical reagents dissolved in water will definitely have cations and anions; for example, familiar divalent iron ions and trivalent aluminium ions, these ions themselves carry a certain charge, and the higher the charge number, the greater the viscosity of the solution.
4. Type and concentration of electrolytes: The electrolytes in water include hydrogen ions and hydroxide ions; if the charge density is too high, it can cause repulsion between ions, reducing the length of the extended chains, which will affect the concentration of polyaluminium chloride.
