●(2)Properties:
①HPAA could be dissolved and separated in two forms of
[HPAA]*-和[HPAA]*- in water of PH **9. It could collate with
Ca2+、Zn2+ to form a protection membrane of 1:1 chelate complex in
the surface of metals. It is usually complexed with Zn2+ to act as
corrosion inbibitor. Also, it is a very good scale inhibitor.
②The COD value is 0.*4gO2／g. When the cooling water contains
dissociative chlorine, it will be oxided; When confronted with
oxidant, it will dissolve ***** thermal stability could indicate
**0℃ with PSC.
●(3) Specification:
Appearance Dark brown liquid
Solid content ≥*0%
Phosphorous (as PO3) ≤3.0%
Density(*0℃ g/cm3) 1.*5—1.*2
pH(1% water solution) 1.0~2.5
After detected with *1P—NMP。It is concluded that this NC***8 has
the content of more than *5％. It is in accordance with Belcor **5
of Ciba-Geigy Company.
●(4) use:
HPAA could be widely used as scale inhibitor and corrosion
inhibitor in cooling water circulation system for steel & iron,
petro-chemitry, power and medical industry. It is usually scale
inhibitor when complexed with zinc ***** is a scale inhibitor
specially suitable for Low Hardness water in South China.
●(5) Packing＆Storage:
In **0Kg or *5Kg in plastic pails，storage is one year．
