Hardware screw rust analysis:
1. When electroplating factory electroplating hardware screws, drying did not dry, resulting in the remaining moisture. Or condensed water forms when it is packaged after drying. Causes a chemical reaction that causes an undesirable occurrence and causes the metal screw to rust.
2. Long-term storage in wet areas, for a long time, the metal screws are slowly corroded and oxidized, causing serious rust.
3. When electroplating hardware screws, the plating is poor, and the electroplating layer is too thin. Causes rust. In summary, analyze the reasons from four aspects. The four directions are: storage environment, plating type, storage method, and use environment.
Hardware screws
Improvement measures: Storage environment: We must put the hardware screws in a suitable environment, should not be too humid, should be ventilated, ventilated, there should not be too much moisture. There should be a bracket that puts the hardware screws out of contact with the ground. Plating types: The plating color should be selected for a longer time for the salt spray test. Plating is good, the plating layer should not be too thin. The preservation method is similar to the storage environment, and it cannot be placed in a wet place. The use environment is similar, and cannot be placed under salinity, acidity, saltiness, high corrosion, high temperature, and high humidity.
