Packaging: Titanium dioxide should be stored in sealed, moisture-proof packaging containers to prevent the ingress of moisture, moisture and other contaminants.
Temperature: Try to store titanium dioxide in a dry, cool environment, away from high temperatures and direct sunlight, to prevent chemical reactions or loss of properties.
Avoid Moisture: Moisture is titanium dioxide's main enemy, causing it to absorb moisture and clump. Therefore, contact between titanium dioxide and moisture should be avoided as much as possible, and desiccants such as silica or drying ovens can be used to absorb moisture.
Avoid vibration: Try to avoid titanium dioxide from vibration and severe shock to prevent particles from rubbing against each other or breaking.
Classified storage: If different types or grades of titanium dioxide need to be stored, they should be stored in classified categories to avoid mixed use or cross-contamination.
