Read： 391 Time：13months ago Source：Transform the World with Simplicity

1.

Zirconia (ZrO2) is an important inorganic chemical raw material with high melting point, high hardness and high chemical stability. It is widely used in ceramics, electronics, aerospace, biomedicine and other fields. However, due to its special physical and chemical properties, zirconium dioxide has certain safety risks during storage and transportation. Therefore, it is essential to establish strict safety storage and transportation regulations.

2. the physical and chemical properties of zirconium dioxide

zirconium dioxide is a white solid, odorless, non-toxic, insoluble in water, slightly soluble in acid, and stable to alkali. At high temperatures, zirconium dioxide has good thermal stability and oxidation resistance. In addition, zirconium dioxide also has good mechanical properties, high hardness and good wear resistance.

3. safety storage specifications

1. The storage place should choose a dry, ventilated and cool place to avoid direct sunlight and high temperature.
2. The storage container shall be well sealed to prevent moisture absorption and contamination of zirconium dioxide.
3. The storage area should be away from fire and heat sources, and it is forbidden to store together with flammable, explosive, acidic, alkaline and other substances.
4. Regularly check the integrity of the storage container to ensure good sealing and prevent leakage.
5. The storage area shall be provided with fire fighting equipment, which shall be inspected and maintained regularly.

4. Safety Transportation Specification

1. Before transportation, check the integrity of the packaging container to ensure good sealing and prevent leakage.
2. During transportation, it should be loaded and unloaded lightly to avoid severe vibration and collision.
3. The transport vehicles shall have the functions of fire prevention, explosion prevention and leakage prevention to ensure the safety of transportation.
4. During transportation, high temperature, open flame and electrostatic spark shall be avoided, and mixed transportation with inflammable, explosive, acidic, alkaline and other substances is prohibited.
5. During transportation, the goods shall be inspected regularly to ensure the safety of the goods.

5. emergency treatment measures

1. In case of leakage, the leakage source should be cut off immediately and recycled to the waste treatment site after mixing with sand, dry lime or soda ash.
2. In the event of a fire, fire extinguishers such as dry powder and foam shall be used immediately to extinguish the fire, and the container shall be cooled with water.
3. In case of contact with eyes or skin, rinse immediately with clean water and seek medical attention.

6. Training and Management

1. Conduct regular training for staff engaged in the storage and transportation of zirconium dioxide to improve safety awareness and operational skills.
2. Regularly inspect and maintain storage and transportation facilities to ensure their safety and reliability.
3. Establish a sound safety management system and emergency plan, and clarify the division of responsibilities and disposal process.

7. conclusion

zirconium dioxide as an important raw material for chemical production, its safe storage and transportation is very important. By formulating strict norms and strengthening training and management, safety risks can be reduced and production safety can be guaranteed. All relevant enterprises shall strictly abide by the specifications to ensure the safe and reliable storage and transportation of zirconium dioxide.
