Analysis of causes of rust on hardware screws:
1. When electroplating hardware screws, the electroplating factory failed to dry them, resulting in residual water vapor. Or condensation water may form during packaging after drying. Cause chemical reactions, produce undesirable occurrences, and cause hardware screws to rust.
2. If stored in a humid place for a long time, the hardware screws will gradually be corroded and oxidized, resulting in severe rust.
3. When electroplating hardware screws, the plating was poor and the plating layer was too thin. Causes rust. All in all, let's analyze the reasons from four aspects. These four directions are:
1. Storage environment
2.Types of electroplating
3.Save method
4.Use environment.
Improvement measures: Storage environment: Hardware screws must be placed in a suitable environment, which should not be too humid, should be ventilated, and should not be in a place with too much moisture. There should be a bracket to hold the hardware screws so they are not in contact with the ground. In terms of electroplating type: you should choose an electroplating color with a longer salt spray test time. When electroplating, it must be plated well, and the electroplated layer should not be too thin. The preservation method is similar to the storage environment, and it cannot be placed in a humid place. The usage environment is similar. It cannot be placed in an environment with high salinity, acidity, high saltiness, high corrosion, high temperature, and high humidity.
