Must-Read for Foreign Trade Customers: Correct Storage Methods and Industry Standards of Calcium Carbide

Physical and Chemical Properties of Calcium Carbide

Calcium carbide, also known as calcium acetylide, has several distinctive physical and chemical properties. It has a high melting point, usually around 2,300 °C. This high - melting characteristic makes it suitable for various high - temperature industrial applications.

Chemically, calcium carbide is highly reactive. When it comes into contact with water, it undergoes a violent reaction to produce acetylene gas and calcium hydroxide. The chemical equation is CaC₂ + 2H₂O → C₂H₂↑+ Ca(OH)₂. Moreover, it exhibits non - solubility in many common solvents but has a certain degree of electrical conductivity due to its ionic nature.

Key Elements of Calcium Carbide Storage Environment

Warehouse Selection

Selecting the right warehouse is crucial for calcium carbide storage. It should be a well - ventilated, dry, and isolated building. The warehouse floor must be level and made of non - absorbent materials to avoid moisture accumulation. For example, a warehouse with a concrete floor can effectively reduce the risk of water seepage.

Temperature and Humidity Control

Maintaining appropriate temperature and humidity levels is essential. The ideal storage temperature should be below 30 °C, and the relative humidity should not exceed 70%. High temperature and humidity can accelerate the reaction between calcium carbide and moisture in the air, leading to product degradation and safety risks.

Sealed Preservation

Calcium carbide must be stored in sealed containers. Drums or special storage bags with good air - tightness can prevent the entry of moisture. Regular inspection of the sealing condition is necessary to ensure that there are no leaks.

Isolation from Hazardous Substances

Calcium carbide should be stored separately from other hazardous substances, especially oxidants and acids. A distance of at least 5 meters should be maintained between calcium carbide storage areas and other incompatible substances to prevent potential chemical reactions.
