Sodium Sulfate
Sodium Sulfate – Versatile Chemical for Detergent Production & Industrial Processes
- Overview
- Recommended Products
- Detergents: Essential raw material for synthetic detergents, functioning as key builder, filler and viscosity modifier in production processes.
- Paper Industry: Act as cooking agent in kraft pulping, bleaching auxiliary, and wastewater treatment additive that neutralizes acidity, improves flocculation and removes suspended solids/color.
- Glass Manufacturing: Applied in float/container/specialty glass as clarifying/fluxing/oxidizing agent to eliminate bubbles, enhance purity, accelerate melting and stabilize coloration.
- Textile Industry: Used in cotton/linen/silk/synthetic fiber dyeing to increase dye uptake, ensure uniform coloring, and optimize pH/dye solubility.
