Properties:
PBTCA has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties and better than other normal organic phosphorus acid, especially under high temperature its antiscale property is far better than that of normal organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.
Applications:
PBTCA 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.
