Description

Trisodium Hydrogen [(Decylimino)Bis(Methylene)]Bisphosphonate is a high-performance organophosphonate compound widely used as a scale and corrosion inhibitor in industrial water treatment systems. Its molecular structure provides excellent chelating and threshold inhibition properties, making it effective against calcium carbonate, calcium sulfate, and barium sulfate scales even at low dosages. This chemical is essential for industries requiring reliable protection for boilers, cooling towers, reverse osmosis membranes, and other critical water-handling equipment.

Application

• Industrial Cooling Water Treatment: Primary application as a highly effective scale inhibitor and dispersant in open recirculating and once-through cooling systems.
• Boiler Water Treatment: Used to control scale formation and prevent under-deposit corrosion in low to medium pressure boilers.
• Reverse Osmosis (RO) & Nanofiltration (NF) Systems: Protects membrane surfaces from inorganic scaling, enhancing flux and extending membrane lifespan.
• Oilfield Water Treatment: Applied in squeeze treatments and continuous injection programs to control scale in downhole formations, well casings, and surface equipment.
• Detergent & Cleaning Formulations: Acts as a builder and chelating agent in industrial and institutional cleaning products to sequester water hardness ions.
• Pulp & Paper Processing: Used to control scale in digesters, washers, and bleach plants, improving operational efficiency.
• Textile Processing: Prevents scale deposition on machinery and fabrics during dyeing and finishing operations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy. Keep away from strong oxidizing agents.
