Product Q&A

Q:What are the main applications of HEDP Na?

It is mainly used as a scale and corrosion inhibitor in industrial circulating cooling water systems, low and medium pressure boilers, oilfield water injection, and oil pipelines. It is also used as a metal cleaning agent in the textile industry, a peroxide stabilizer and fixing agent in dyeing, and a complexing agent in cyanide-free electroplating.

Q:What is the recommended dosage of HEDP Na?

As a scale inhibitor: 2~20 mg/L. As a corrosion inhibitor: 100~200 mg/L. As a cleaning agent: 1000~2000 mg/L. It is usually used together with polycarboxylic acid type scale dispersants for better performance.

Q:What is the difference between HEDP Na and HEDP (acid)?

HEDP Na is the mono-sodium salt of HEDP. It has better water solubility and is suitable for acidic formulations. Both are organic phosphonic acid scale and corrosion inhibitors with similar performance, but the sodium salt is easier to compound in certain formulations.

Q:What are the packaging and storage conditions?

It is packed in plastic drums, 30kg or 250kg per drum, or customized as per customer requirements. Store in a cool, dry indoor area, away from direct sunlight. Shelf life is 10 months.

Q:What precautions should be taken when handling HEDP Na?

HEDP Na is acidic. Wear protective equipment during operation and avoid direct contact with skin and eyes. In case of contact, rinse immediately with plenty of water.
