What is Industrial-Grade Trisodium Phosphate Dodecahydrate?
Trisodium Phosphate Dodecahydrate (TSP·12H₂O), with the chemical formula Na₃PO₄·12H₂O, is the most common and stable hydrate form of TSP. Industrial-grade products are typically colorless or white crystalline granules with high purity, which readily effloresce in dry air. Its high alkalinity, excellent water-softening capability, and buffering properties make it an essential chemical across multiple industries.
·Key Characteristics and Advantages
1. Strong alkaline cleaning power: Effectively breaks down grease, proteins, and organic dirt, suitable for metal pretreatment and heavy-duty cleaning.
2.Water softening and chelating capability: Strongly chelates calcium and magnesium ions to prevent scale formation, significantly improving cleaning and water treatment efficiency.
3.Buffering and stabilizing action: Stabilizes solution pH, maintaining a consistent chemical environment in various industrial processes.
4.Good solubility: Exhibits good solubility in both cold and hot water, facilitating quick preparation of working solutions.

·Main Application Areas
1.Industrial cleaning: Boiler and pipeline descaling, metal parts degreasing and pre-phosphating, heavy-duty equipment and site cleaning.
2.Water treatment: Used as a softener, corrosion and scale inhibitor in industrial cooling circulation systems and boiler water treatment.
3.Textile dyeing: Serves as a hydrogen peroxide bleaching stabilizer and a mercerizing assistant for cotton fabrics to enhance process efficiency and dye adhesion.
4.Construction materials and ceramics: Used as a cement retarder, ceramic glaze dispersant, etc.
5.Synthetic detergents: Acts as a key builder in industrial detergents and cleaners, providing alkalinity and water softening.
·Usage Precautions
1.Safety protection: Wear goggles, dust masks, and rubber gloves during operation to avoid dust inhalation or direct contact with skin and eyes.
2.Environmental handling: Phosphorus-containing wastewater must be treated to meet standards before discharge to prevent water eutrophication.
3.Storage conditions: Store in sealed containers in a cool, dry, and well-ventilated warehouse to prevent efflorescence or deliquescence.
·Market Prospects and Sustainable Development
1.Process optimization: Develop compound formulations and precise dosing processes to reduce single-use dosage and improve efficiency.
2.Closed-loop management: Promote wastewater treatment and phosphate recovery technologies in specific industrial systems to achieve resource circulation.
