Chemical Structure:
Composed of two 1,6-hexamethylene (i.e., hexamethylene diamine) molecules connected to a triamine group and five methylphosphonic acid groups.
Appearance and State:
Typically appears as a transparent liquid ranging in color from yellow to reddish-brown.
Possesses good flowability.
Physical Properties:
Density: Approximately 1.40 g/cm³.
pH value (1% aqueous solution): approximately 2.0–3.0.
Solubility:
Soluble in water and most organic solvents.
Main Applications
BHMTPMPA is primarily used in the following areas:
Water treatment chemicals:
Used as a high-performance scale inhibitor and corrosion inhibitor.
Particularly suitable for water treatment systems operating at high temperatures, high hardness, and high pH values.
Industrial circulating cooling systems:
Effectively prevents scaling, maintaining system cleanliness and efficient operation.
Reduces equipment corrosion rates and extends service life.
Oilfield chemicals:
Used in oil and gas field development to mitigate formation blockage and enhance recovery rates.
Mode of action
Scale inhibition mechanism: Forms stable complexes with calcium, magnesium, and other ions in water, preventing their deposition on pipes and equipment to form scale layers.
Corrosion Inhibition: Forms a protective layer on metal surfaces, preventing direct contact between oxygen and water molecules and the metal, thereby slowing down the corrosion process.
Safety Precautions
Wear appropriate protective gear, such as gloves and goggles, when handling.
Store in a cool, dry place, away from heat sources and incompatible materials.
If ingested accidentally, seek medical assistance immediately and inform the doctor of the specific substance name.
Precautions
Read the product manual carefully before use and strictly follow the recommended concentration and usage conditions.
Dispose of waste chemicals in accordance with local environmental regulations and relevant standards.
In summary, BHMTPMPA plays a crucial role in numerous industrial fields due to its outstanding performance, but safety precautions must be strictly adhered to during use.
