Metal chelating is a type of chemical that can form a stable metal matched object. They usually have a specific molecular structure containing the donor atom, which can form a chemical bond with the empty or set position in the metal ions. Metal chelating plays an important role in water treatment, and its main role is as follows:
Metal ions Removal: Metal chelating agents can complement the metal ions in the water to form a stable metal matched. These metal mathematics can prevent metal ions from precipitating or generating incurable sediments, so that metal ions maintain a stable concentration in water.
Anti -scale and dirt: Metal chelating agents can collateral effects with hardness ions in the water (such as calcium ions and magnesium ions) to prevent hardness ions from scaling on the surface of the water pipe and equipment. In addition, metal chelating agents can also be used to remove the formal dirt and restore the normal work of the device.
Antioxidant and corrosion: Some metal chelating agents have antioxidant and corrosion performance, which can form a protective film with the metal surface to prevent metal corrosion and oxidation reactions. This helps extend the service life of the equipment and maintain the stability of the water treatment system.
Catalytic reaction: Metal ions in metal chelating agents can be used as a chemical response during the catalyst to participate in the water treatment process, accelerating the reaction rate and improving the reaction efficiency.
In general, metal chelating agents play a variety of functions such as stabilized metal ions, anti -scale anti -scale, anti -oxidation corrosion, and catalytic reactions in water treatment to help maintain the normal operation of the water treatment system and the stability of water quality.
