Based on the previously mentioned basic storage conditions for precision metal parts, their dryness can be comprehensively maintained through three measures: temperature and humidity control, standardized stacking, and auxiliary protection.
Precise Temperature and Humidity Control: Configure constant temperature and humidity units to stabilize the ambient temperature at 15-25℃ and the relative humidity at 30%-40%, preventing excessive temperature differences that could cause condensation on the surface.
During periods of high humidity, operate dehumidifiers, using desiccants such as silica gel or molecular sieves. Localized enclosed spaces can achieve even lower humidity, inhibiting moisture adhesion at the source.
Standardized Stacking to Prevent Moisture: Elevate all workpieces at least 50mm using supports or moisture-proof mats to completely remove them from ground moisture. Leave ventilation gaps between stacks to prevent localized moisture accumulation.
Store different materials separately to avoid electrochemical corrosion caused by mixed storage, and keep them away from doors, windows, pipes, and other areas prone to moisture penetration.
Auxiliary Sealing Protection: Single or small batches of workpieces can be vacuum-sealed and filled with dry nitrogen to completely isolate them from external moisture.
Before the workpieces are put into storage, the surface water stains and oil stains are thoroughly cleaned, and then wrapped with vapor phase rust inhibitor film to further enhance the drying and protection effect.
