Usage
PBTC is an effective agent that functions as a scale and corrosion inhibitor. With its high efficiency, PBTC is widely used in various applications such as circulating cool water systems and oilfield refill water systems. It proves to be an excellent stabilizer for zinc salt. In combination with zinc salt and copolymer, PBTC demonstrates its superior performance as a scale and corrosion inhibitor. It excels in environments characterized by high temperatures, high hardness, high alkali content, and high concentration index.
Moreover, PBTC finds utility in the field of lavation as a chelating agent and metal detergent. Its versatile properties make it a sought-after solution for tackling complex cleaning challenges.
To optimize its effectiveness, PBTC is commonly paired with other Water Treatment Chemicals like zinc salt, copolymer, organophosphine, imidazole, amongst others. However, if it is used singly, a recommended dosage of 5-15mg/L is advisable.
Properties
PBTC is a remarkable chemical compound that provides outstanding scale and corrosion inhibition properties. It exhibits structural characteristics of both phosphoric and carboxylic acid groups while containing a low level of phosphoric content. In comparison to organophosphines, PBTC possesses superior anti-scaling properties under high temperatures. Its exceptional properties extend to improving zinc salt solubility, demonstrating excellent tolerance to chlorine oxidation, and fostering synergies in composites. PBTC is a vital component in many industrial and residential applications for water treatment and management.
