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

3.Application range&using method
As high-efficient agent of scale and corrosion inhibitor, PBTCA is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor;
It is the excellent stabilizer for zinc salt. It is suitable to composite with zinc salt and copolymer. It 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.
PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of ***5mg/L is preferred.
