Sodium Trimetaphosphate (STMP) is a chemical compound with the molecular formula Na3P3O9. It is a colorless or white crystalline powder that is soluble in water. STMP is a member of the polyphosphate family of compounds and is used in a variety of industrial applications like:
STMP is used as a water softener in the textile, detergent, and paper industries. It helps to remove calcium and magnesium ions from hard water, which can interfere with the performance of detergents and cause scaling in industrial equipment.
STMP is added to detergents as a builder, which means it enhances the cleaning power of the detergent by binding to metal ions in the water and preventing them from interfering with the cleaning process.
STMP is used as a dispersing agent in paint and ceramic manufacturing to help distribute pigments and other additives evenly throughout the product.
STMP is used in metal treatment processes to prevent the formation of rust and other types of corrosion. It is added to metal coatings and surface treatments to provide long-lasting protection against environmental factors.
STMP is used in oil drilling as a stabilizer and deflocculant. It helps to prevent clay particles from swelling and clogging the drilling equipment.
STMP is used in textile processing as a sequestering agent. It helps to remove metal ions from the fabric and prevent discoloration and other types of damage during processing.
