The Chinese name of HPAA, 2-hydroxyphosphonoacetic acid, is more widely used in the water treatment industry. It is an excellent corrosion inhibitor, which can be used to prevent metal corrosion and sediment formation in water. In addition, HPAA can be used in water treatment processes in petrochemical, textile, paper, leather and other industries.
It should be noted that HPAA is an organophosphate compound, which is toxic and irritating. In the process of use, care should be taken to avoid direct contact with skin and eyes, such as inadvertent contact, should be immediately flushed with large amounts of water, and promptly seek medical attention. In addition, HPAA should be stored in a cool, dry, well-ventilated place, avoiding contact with oxidising agents, acids and other substances to avoid dangerous reactions.
