What is the reason for Galvanized Wire Rust?

Galvanized Wire is a very distinctive wire that is extremely durable, has good corrosion resistance, and is resistant to Rust. Therefore, Galvanized Wire is used in construction, screen making, and crafts. When we use Galvanized Wire, we sometimes find problems with Rust in Galvanized Wire. What are the factors that contribute to Galvanized Wire Rust?

①In fact, the Galvanized Wire atmosphere has the greatest influence on the corrosion of Galvanized Wire. When the atmospheric humidity is higher than the critical humidity, the water film or water droplets appear on the surface of Galvanized Wire. If the harmful impurities contained in the atmosphere dissolve in the water film and water droplets, it becomes an electrolyte and aggravates the rust. Be sure to pay attention when using Galvanized Wire.

②Galvanized Wire atmospheric water vapor content will also affect the quality of Galvanized Wire, with increasing temperature, high temperature causes rust to increase, especially in humid environments, the higher the temperature, the faster the rust. When the relative humidity is low, the effect of temperature on corrosion is not obvious, but when it is higher than the critical humidity, the amount of corrosion increases sharply with the increase of temperature. In addition, if there is a temperature difference between the atmosphere and the metal, condensed water is formed on the surface of the metal having a low temperature, which also leads to Galvanized Wire Rust.
