1. Necessary Pre-Storage Treatment Apply a Temporary Rust Inhibitor: Immediately after drying, spray a layer of water-based rust inhibitor or quick-dr

1. Visual and Tactile Inspection (Most Direct) Surface Condition: A dried metal can should be free of water stains and condensation, and the inner wal

1. Incomplete or inadequate drying (High risk) Air drying at room temperature: After surface moisture evaporates, residual moisture inside or at weld

1. During the drying process: Control the environment and heat transfer methods to prevent moisture re-adhesion. Use a closed-loop hot air circulation

1. Compressed Air Drying (Recommended for Initial Drying): Use clean, dry compressed air (pressure ≤ 0.6 MPa) to blow away most of the moisture fro
