First, with the use of performance:
HPAA chemical stability, easy hydrolysis, can not easily be damaged by acid-base, the use of safe and reliable, non-toxic pollution-free, HPAA can improve the solubility of zinc, with a strong role in corrosion, HPAA corrosion performance than HEDP, EDTMP high-5 ~ 8 times. HPAA with low-molecular-weight polymer components together with the organic corrosion and scale inhibitors performance.

Third, the scope of application and use of
HPAA mainly used as the cathode metal corrosion inhibitor, is widely used in iron and steel, petrochemical, power and pharmaceutical industries circulating cooling water system of corrosion and scale inhibitors, suitable for use in the South China low hardness and easy to corrosion inhibitor water quality, HPAA and zinc mixed better.
Fourth, packaging and storage
HPAA with plastic barrel, 30kg. Stored in a cool room, storage for a period of twelve months.
