NaN02 is an oxidizing corrosion inhibitor suitable for water treatment with low or ultra-low hardness. This product is toxic, so it is mainly used for closed circulating cooling water system, is a dangerous corrosion inhibitor, when the use concentration is insufficient, not only no corrosion inhibition, but accelerate corrosion, the use concentration is usually 300 ~ 500mg/L. The best pH range of water quality is 8-10, so it is often used together with Na2C03 of 300 ~ /L. When the pH of water quality is <6, it decomposes and cannot inhibit corrosion. Often combined with sodium molybdate, on the one hand to play a synergistic effect, on the other hand to reduce the amount of both. It is only suitable for black metal rust prevention, and is ineffective for non-ferrous metals such as copper, and even has corrosion effect.
