Product Description
Product Description
Chemical property:Industrial products are gray, yellow brown, or black solids, with those containing high levels of calcium carbide appearing purple. The newly fractured surface of calcium carbide has a shiny appearance, but when exposed to air, it loses its luster due to absorption of moisture and appears gray white. Relative density 2.22. Industrial products generally contain 80% calcium carbide. Melting point 2300 ºC. It can conduct electricity, and the higher the purity, the easier it is to conduct electricity. The chemical properties are very active and can react with many gases and solutions at appropriate temperatures. Intense decomposition in water produces acetylene gas and calcium hydroxide, and releases a large amount of heat. Intense chemical reactions can occur with chlorine, hydrogen chloride, sulfur, phosphorus, ethanol, etc. at high temperatures.
Application:The interaction between calcium carbide and water can generate acetylene gas, which is an important basic raw material for organic synthesis. Acetylene gas can be used to produce polyvinyl chloride, chloroprene rubber, cyanamide calcium, acetic acid, vinyl acetate ethanol and its derivatives, and cyanide
Compounds, dicyandiamide, acetone, etc. Calcium carbide reacts with nitrogen to generate lime nitrogen, which can be used as agricultural fertilizer. Using calcium carbide to produce acetylene for metal cutting and welding.| Product name | Calcium Carbide | Color | Grey, yellowish brown or black |

Our Advantages
Safety:Calcium carbide powder is irritating, causing sweat on the skin to generate Ca (OH) 2, which burns the skin until it ulcerates. Inhalation can harm a person's respiratory system. Wear goggles, masks, and gloves during work. During transportation and before storage, the gas in the barrel must be completely discharged. It is strictly prohibited to roll, reposition, or collide the barrel to prevent sparks and explosions. When the packaging is damaged, welding and soldering are strictly prohibited. Water is prohibited for firefighting. Only sand or carbon dioxide can be used for firefighting, and dry sodium carbonate (soda ash powder) can also be used for firefighting. If dizziness, headache, or vomiting is found, it should be immediately moved to a place with fresh air. Severe cases should be sent to the hospital for treatment. Packed in iron drums with a wall thickness of no less than 1mm, in units of 100kg or 200kg. The side of the iron bucket is marked with paint with the words "carbide to avoid water and fire".
Calcium carbide should be stored in a dry, cool, and ventilated warehouse, isolated from combustible materials and strong acids. It is best to store it in a dedicated warehouse. Strictly prevent contact with water and moisture. Before entering the warehouse, the acetylene gas in the barrel should be vented. The storage period should be 6-12 months.
