Atmospheric relative humidity At the same temperature, the percentage of water vapor content and water vapor saturation in the atmosphere is called relative humidity. At a certain relative humidity, the corrosion rate of the metal anti-rust oil is small, but higher than the relative humidity, the corrosion rate suddenly increases.
This relative humidity is called critical humidity. Many metals have a critical humidity between 50% and 80%, while steel has a critical humidity of around 75%. Atmospheric relative humidity has the greatest impact on metal corrosion. When the humidity in the atmosphere is higher than the critical humidity, water film or water droplets may appear on the metal surface. If the atmosphere contains harmful impurities, it dissolves in water film, water droplets, electrolytes and exacerbates corrosion.Among the hardware products produced by Galvanized iron wire manufacturers, the main problem in the storage work is to prevent corrosion. Metal corrosion is caused by chemical or electrochemical action of the surrounding medium. According to different media, it is divided into atmospheric corrosion, soil corrosion, seawater corrosion, and bacterial corrosion. Atmospheric corrosion is the most common because metal products are in contact with the atmosphere during processing, transportation, and storage, and there are always atmospheric corrosion conditions.
