China Manufacturer Antirusting Agent 1,2,3-Benztriazole BTA Cas 95-14-7

Appplication:

Benzotriazole has an anti-corrosion effect on metal materials such as copper, aluminum, cast iron, nickel, and zinc. It can be used in combination with a variety of corrosion inhibitors, such as chromates, polyphosphates, molybdates, silicates, nitrites, ATMP, HEDP, EDTMP, etc., to improve the corrosion inhibition effect. The corrosion inhibition effect is very good in closed-circulation cooling water systems. It can be used in combination with a variety of scale inhibitors and bactericides and algaecides. Benzotriazole does not interfere with the corrosion inhibition of polyphosphates and has strong resistance to oxidation. However, when it exists with free chlorine, it loses its corrosion inhibition effect on copper, and after the chlorine disappears, its corrosion inhibition effect is restored. Its use concentration is generally 1-2 mg/L, and its corrosion inhibition effect is very good in the pH range of 5.5 to 10, but the corrosion inhibition effect is reduced in media with low pH values.
