Unintentional hand sweat can cause corrosion on metal surfaces
Thread Content
Human sweat is a colorless or pale yellow, salty-tasting, weakly acidic liquid with a pH value of 5–6. In addition to sodium, potassium, calcium, and magnesium salts, it also contains small amounts of organic acids such as urea, lactic acid, and citric acid. When sweat comes into contact with metal, a layer of sweat film forms on the surface of the metal. This sweat film exerts an electrochemical effect on the metal, causing it to corrode. It is inevitable for people to sweat, and to prevent rusting caused by sweaty hands, workers should wear gloves when touching metal surfaces; they should not touch those surfaces with their bare hands.
Additionally, to protect metal surfaces from corrosion caused by sweat, it’s advisable to regularly clean and maintain them, using rust inhibitors or applying a protective coating. Furthermore, keeping the hands dry is also an important measure to prevent metal corrosion caused by sweaty hands; antiperspirants or other products that inhibit sweat secretion can be used to control hand sweating. Proper care and attention to hand hygiene can also reduce the impact of corrosion on metal surfaces. .
