Why PBTC has the function of scale and corrosion inhibition

PBTC (Phosphonobutane-1,2,4-Tricarboxylic Acid) has the function of scale and corrosion inhibition due to its specific chemical properties. Here are the main reasons why PBTC exhibits scale and corrosion inhibition:

Threshold Effect: PBTC acts as a threshold inhibitor by forming a protective barrier on metal surfaces. It inhibits the formation of scale by binding to metal ions, such as calcium and magnesium, present in the water. This binding process forms a thin and stable layer of PBTC-metal complex on the metal surface, preventing the precipitation and deposition of scale-forming substances.

Crystal Distortion Effect: PBTC can distort the crystal structure of scale-forming minerals, such as calcium carbonate and calcium phosphate. This distortion prevents the growth and adhesion of these minerals, making it difficult for them to form scale on surfaces.

Dispersing Action: PBTC has dispersing properties that help to keep scale-forming particles in suspension. It prevents their agglomeration and deposition on surfaces by keeping them dispersed throughout the water. This action aids in the prevention of scale formation.

Corrosion Inhibition: PBTC provides corrosion inhibition by forming a protective film on metal surfaces. This film acts as a physical barrier, reducing the interaction between the metal and corrosive substances present in the water. It helps to mitigate the rate of corrosion and protect the metal from degradation.

Stability: PBTC is stable over a wide range of temperature and pH conditions, allowing it to maintain its scale and corrosion inhibition properties in various environments. It remains effective even under high-temperature and acidic conditions, making it suitable for diverse industrial applications.

It is important to follow the manufacturer's instructions and guidelines for proper usage and dosage of PBTC to ensure optimal scale and corrosion inhibition effects.
