Product Description

Water Treatment Scale Corrosion Inhibitor Chemicals 50% PBTCA/PBTC Phosphonate Cas:37971-36-1

PRODUCT DETAILED

 2-Phosphonobutane -1,2,4-Tricarboxylic Acid PBTC is used  as corrosion inhibitor and scale inhibitor, it is a water treatment agent with high scale inhibitor and corrosion inhibitor performance, strong chemical stability and low toxicity.Under the condition of high temperature, high hardness, high alkalinity, PBTC also has good corrosion inhibition performance, and Ca2+.2 n2 +.Mg2+ plasma has excellent complexation ability.It has a good synergistic inhibition effect with zinc salt and polyphosphate.Can be used in petroleum, chemical, power generation, industrial boiler water treatment.The concentration ratio of circulating cooling water can be increased to more than 7.It can be used as chelating agent and metal cleaning agent in detergent industry.

PRODUCT APPLICATION

PBTC is designed as a 50% aqueous solution to control calcium scale formation and precipitation in highly stressed alkaline Industrial Water Treatment (IWT) and boiler systems. PBTC has been widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for applications in industrial water treatment and industrial cleaning.
PBTC is a high efficient agent as scale and corrosion inhibitor. 
PBTC is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer.  
PBTC can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent. 
PBTC is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.
