benzotriazole on copper, aluminum, cast iron, nickel, zinc and other metal materials have anti-corrosion effect. Can be combined with a variety of corrosion inhibitors, such as with chromate, polymeric phosphate, molybdate, silicate, nitrite, ATMP, HEDP, EDTMP, etc., can improve the corrosion inhibition effect. The corrosion inhibition effect is very good in the closed circulating cooling water system. Can be used with a variety of scale inhibitors, bactericidal algaecide, benzotriazole on the corrosion inhibition of polyphosphate does not interfere, the oxidation resistance is very strong. However, when it exists together with free chlorine, the corrosion inhibition of copper is lost, and after the disappearance of chlorine, the corrosion inhibition is restored. Its concentration is generally 1-2mg/L, and the corrosion inhibition is very good in the range of pH 5.5~10, but the corrosion inhibition is reduced in the medium with low pH value.
Did you know that the molar mass of water is key to understanding many chemical processes? Whether you're a student or just curious, grasping this concept is crucial in chemistry. In this post, we’ll explore how to calculate the molar mass of water and why it matters in both science and everyday life.
as a corrosion and Scale Inhibitor, it is a water treatment agent with high scale inhibition and corrosion inhibition performance, strong chemical stability and low toxicity. In the high temperature, high hardness, high alkalinity conditions, PBTC also has good corrosion inhibition performance, and Ca2 .2 n2 .Mg2 plasma has excellent complexation ability. It has a good synergistic effect with zinc salt and polyphosphate. Can be used for petroleum, chemical, power generation, industrial boiler water treatment. The concentration ratio of the circulating cooling water can be increased to more than 7. In the detergent industry can be used as chelating agent and metal cleaning agent.
JIANGYIN TRUST INTERNATIONAL INC was established in 1996, dedicated to the production and export of water treatment chemicals, intermediates, and other chemicals.
