  • New: Corrosion Types of Chlorocyclotriphosphazenes

Today, we are concerned about the type of corrosion of hexachlorocyclotriphosphazene knowledge, I hope we can take some time to look at the following content, because it is for everyone to understand the product is a certain help.
1, uniform corrosion
Hexachlorocyclotriphosphazene corrosion of metal materials is electrochemical corrosion. The corrosion is in accordance with the electrochemical process, that is, the anode produces metal dissolution (uniform corrosion), the cathode precipitation of hydrogen.
2, stress corrosion
Stress corrosion is the material in the stress and the role of specific media caused by the common material cracking. In the hexachlorocyclotriphosphazene carbon steel and Monel alloy are likely to stress corrosion cracking. This stress corrosion is exacerbated by increasing temperature.
3, hydrogen bubbling and hydrogen embrittlement
Medium and carbon steel contact to produce iron fluoride and hydrogen atoms, Fe + 2HF-FeF2 + 2H, iron fluoride is a dense corrosive, attached to the metal surface to form a protective film, the hexachlorocyclotriphosphonated Diffusion rate is reduced. Protect the device. But when the medium temperature exceeds 65 degrees Celsius, the layer of corrosion of the protective film will peel off, so that the metal continues to be corroded.
