1. Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds, such as synthetic rubber, artificial resin, acetone, ketene, carbon black, etc; At the same time, acetylene oxygen flame is widely used in metal welding and cutting.
2. When powdered calcium carbide is heated with nitrogen, it reacts to produce calcium cyanamide, that is, lime nitrogen. When heated, lime nitrogen reacts with salt to produce cyanide melt, which is used in gold mining and non-ferrous metal industry.
3. Calcium carbide itself can be used as desulfurizer in iron and steel industry.
matters needing attention
1. Calcium carbide will not burn when dry. It can quickly produce highly flammable acetylene gas in the presence of water or moisture. When it reaches a certain concentration in the air, explosion and other disasters will occur. Calcium carbide can react violently with acids.
2. Calcium carbide is easy to damage the skin, causing skin itching, inflammation, skin burns, etc.
3. Calcium carbide must be stored in a cool, dry and well ventilated warehouse. It must be sealed and protected from moisture. And stored separately from acids, alcohols, etc.
