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.
