Application of Trisodium phosphate (TSP) in various industries

1. Cleaning & Degreasing

TSP is a powerful alkaline cleaning agent used in various industries due to its ability to break down grease, oil, and dirt.

  • Industrial Cleaning: Used in factories and workshops to clean machinery, floors, and tools.

  • Household Cleaning: Found in heavy-duty detergents for washing walls, floors, and driveways.

  • Paint Preparation: Removes grease and dirt from walls before painting for better adhesion.

  • Graffiti Removal: Helps in cleaning painted surfaces before restoration.


2. Water Treatment

TSP is widely used to regulate pH and prevent scale buildup in industrial water systems.

  • Boiler Water Treatment: Prevents scale formation and controls alkalinity.

  • Cooling Towers: Helps control pH and reduces corrosion in cooling systems.

  • Wastewater Treatment: Enhances removal of heavy metals and helps in sludge treatment.

  • Swimming Pools: Used to control pH levels and clean pool surfaces.


3. Metal Surface Preparation

TSP is a key component in metal cleaning and preparation processes.

  • Degreasing Metal Parts: Removes oil and grease from metal before welding or coating.

  • Rust Removal: Helps eliminate rust and oxidation before painting.

  • Phosphating Processes: Used to prepare metal surfaces for coatings by creating a phosphate layer that improves paint adhesion.


4. Textile Industry

TSP plays an important role in textile processing, dyeing, and fabric treatment.

  • Dyeing & Bleaching: Acts as a buffering agent to maintain the necessary pH during fabric processing.

  • Stain Removal: Used in detergents for effective removal of grease, ink, and sweat stains.

  • Washing & Mercerizing: Helps in cleaning and strengthening cotton fabrics.


5. Paper & Pulp Industry

TSP improves efficiency in paper manufacturing and recycling.

  • pH Control: Used to adjust pH levels in the paper bleaching process.

  • Ink Removal in Recycling: Aids in de-inking and preparing used paper for repulping.

  • Smoothing Paper Surface: Helps in chemical treatments that enhance paper quality.


6. Food Processing (Technical Applications Only)

While food-grade TSP is used as a food additive, industrial-grade TSP is applied in cleaning and maintenance.

  • Equipment Cleaning: Used in food processing plants to remove grease and sanitize machinery.

  • Dairy & Meat Processing: Helps in degreasing and cleaning tanks, pipes, and surfaces.

  • pH Control in Processing Plants: Maintains alkaline conditions to prevent microbial growth.


7. Construction Industry

TSP is used in cement, masonry, and painting applications.

  • Cement Additive: Regulates setting time and improves durability.

  • Etching Concrete Surfaces: Prepares concrete surfaces before painting or sealing.

  • Mold & Mildew Removal: Used to clean mold-infested walls and surfaces.


8. Automotive & Aerospace

TSP is effective in cleaning and degreasing engine parts and aerospace components.

  • Engine Cleaning: Removes oil, grease, and carbon buildup from automotive and industrial engines.

  • Aircraft Maintenance: Used to clean metal surfaces and aircraft exteriors.

  • Brake and Transmission Parts Cleaning: Helps in degreasing and preparing components for assembly.
