Application:
PBTC controls scale where halogen-based biocides or hypochlorite bleach are employed. Controls calcium scale formation in high stressed alkaline conditions. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.
PBTC is widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for applications in industrial water treatment and industrial cleaning. It 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.
Package and Storage:
packed in 200L HDPE drum, 1000L IBC and ISO TANK.
Storage for 1 year in room shady and dry place.
Our factory has advanced production equipment, adopts high-quality raw materials, strictly abides by advanced production technology, and establishes a strict quality management system to produce Water Treatment Chemical Scale Corrosion Inhibitor PBTCA that can reach the international advanced level. We provide personalized services according to the characteristics of different types of customers, and proactively formulate perfect service standards for more customers. We actively attract talents, learn from others' strengths, and uphold the concept of integrity, professionalism and win-win.
