ABSTRACT: The mixture consisted of benzotriazole (BTA), chitosan (CTS), polyacrylic acid and
zinc salt has
been investigated as a corrosion and scale inhibitor of
A3 carbon steel in cooling water. The scale and corrosion inhibition efficiency
was evaluated by static anti-scaling teat together with rotary coupon test.
Compared with the phosphorus corrosion and scale inhibitor, the corrosion inhibition rate
and scale inhibition rate of it increased respectively by 2.51% and 1.16%. As the corrosion and scale inhibitor
is phosphate-free, it won’t cause eutrophication, considering
the product performance and environmental influence, the phosphate-free corrosion and scale inhibitor is
superior to the traditional one.
