Corrosion inhibitor PBTC 50% is an efficient scale and corrosion inhibitor.

It is an excellent stabilizer of zinc salt.

It is widely used as scale and corrosion inhibitor in circulating cooling water system and oilfield reinjection system. It is suitable for mixing with zinc salt and copolymer.

Can be used for high temperature, high hardness, high alkali, high concentration index occasions;

Used as a chelating agent and metal detergent in the toiletry field;

The corrosion inhibitor PBTC 50% is usually combined with zinc, salt, copolymer, organic phosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/L is appropriate.

Details

PBTCA has low phosphorus content, due to its structural characteristics of phosphonic acid and carboxylic acid, so that it has good scale inhibition and corrosion inhibition performance, better than commonly used organic phosphonic acid, especially at high temperature scale inhibition performance is much better than commonly used organic phosphonic acid, can improve the solubility of zinc, good oxidation resistance to chlorine, good coordination. PBTCA is widely used in the compound of high efficiency corrosion and scale inhibitors, and has excellent performance. It is also an excellent stabilizer of zinc salt. Widely used in circulating cooling water system and oilfield water injection system corrosion and scale inhibition, especially suitable for use with zinc salt, copolymer, can be used in high temperature, high hardness, high alkali and need to operate under high concentration occasions, PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry.
