Industry Wise Application
Detergents & Cleaning
- Detergent Builder:Replaces sodium tripolyphosphate (STPP) to soften water by sequestering calcium and magnesium ions.
- Heavy-Duty Degreaser:Used in industrial-strength cleaners, floor cleaners, and degreasers to remove oil and grease.
- Commercial Dishwashing:Key ingredient in dishwashing liquids and laundry detergent additives for excellent stain removal.
- Institutional Sanitizers:Used to clean food processing equipment, processing lines, and in dairy cleaning operations.
- Bottle Washing:Used in the brewing and beverage industry to clean carbonated drink bottles.
Metal Surface Treatment & Protection
- Metal Cleaner:Removes grease and dirt from metal surfaces.
- Corrosion Inhibitor:Protects metals—particularly aluminum and zinc—from corrosion during cleaning processes.
- Electroplating/Rust Removal:Used in rust removal formulations and as a pH buffer.
- Metalworking:Acts as a rust inhibitor in cutting fluids
Construction & Refractories
- Concrete Additive:Acts as a concrete hardener, densifier, and accelerator for early strength development.
- Adhesive in Refractories:Used as a binder in high-temperature bricks, refractory materials, and concrete.
- Soil Stabilization: Used to harden soil for construction applications
Textile, Paper & Ceramic Industries
- Textile Processing:Used as a stabilizer for hydrogen peroxide bleaching and as a detergent in the boiling/dyeing of cotton yarns.
- Paper De-inking:Aids in removing ink during recycling of waste paper.
- Ceramic Deflocculant:Used to thin ceramic slurries, reducing water content while improving viscosity and fluidity during casting.
Other Applications
