Performance and Usage
Chelation performance: ATMP has good chelation ability and can effectively bind to metal ions, preventing mineral deposition and scale formation in the water.
Anti-scale performance: ATMP can effectively prevent the formation of scale in water, especially the formation of calcium carbonate scale. This makes it widely used in circulating cooling water systems, boiler water treatment, oilfield water treatment, etc.
Corrosion inhibition: At high concentrations in water, ATMP shows good corrosion inhibition effect and can reduce corrosion of metal equipment or pipelines.
Packaging & Storage
ATMP liquid is packed in plastic drums, 30kg or 250kg per drum; ATMP solids are packaged in plastic woven bags lined with polyethylene bags, each bag has a net weight of 25kg, which can also be determined according to user needs. Store in a cool and ventilated place indoors, moisture-proof, strictly protected from sunlight, and have a storage period of ten months.
FAQ - Technical & Supply Chain
-
Q:
Is Amino Trimethylene Phosphonic Acid (CAS 6419-19-8) typically supplied as a powder or solution?
A: Industrial supply is commonly provided as a 50% aqueous solution for ease of dosing in liquid systems, though crystalline powder forms are available for specialized solid formulations or cold-climate transport. -
Q:
What is the primary function of ATMP in cooling water systems?
A: It acts as a threshold antiscalant that distorts the crystal growth of calcium salts, thereby preventing scale deposition on heat exchanger surfaces at low stoichiometric dosages.
