Decolorization Sand
Bleaching Earth / Silica Bleaching Powder
Key Features: High-activity silica-based adsorbent with excellent decolorization and purification performance. Effectively removes pigments, gums, and impurities from oils and chemicals.
Bleaching Silica Gel (Decolorizing Adsorbent)
Bleaching Silica Gel is a high-performance adsorbent material mainly composed of high-purity silicon dioxide (SiOβ). With its high surface area, developed pore structure, and strong adsorption capacity, it is widely used for decolorization, purification, and impurity removal in various liquid systems.
This product effectively removes pigments, colloids, impurities, and trace metals, significantly improving the clarity, stability, and quality of end products.
π Applications
- Edible oils and vegetable oil refining
- Lubricating oils and mineral oil purification
- Petrochemical processing
- Pharmaceutical intermediates decolorization
- Sugar solutions and alcoholic beverages purification
- Dyes, solvents, and chemical liquid treatment
