Calcium carbide has several specific uses, and here are some primary applications:
1.Acetylene Gas Production: Calcium carbide is a major source of acetylene gas. When calcium carbide reacts with water, it generates acetylene gas. Acetylene gas finds widespread use in welding, cutting, metal processing, as well as in lighting and heating.
2.Organic Synthesis: As a chemical raw material, calcium carbide is employed in the production of various organic compounds. For example, it can be used to synthesize vinyl chloride, chloroprene rubber, synthetic resins, and more.
3.Oxyacetylene Welding:The acetylene gas produced from calcium carbide, when mixed with oxygen, is utilized in oxyacetylene welding, extensively applied in metal welding and cutting.
4.Calcium Cyanamide Production: Calcium carbide can also be used to produce calcium cyanamide, a chemical fertilizer used for plant growth.
5.Desulfurizing Agent: In some industries, calcium carbide acts as a desulfurizing agent, helping to reduce sulfur oxide emissions from combustion.
Please Note:It's important to note that due to the characteristics of calcium carbide, especially its tendency to produce acetylene gas upon contact with water, its applications need to adhere to safety and environmental standards.
Q: What is the primary use of calcium carbide?
A: Calcium carbide is primarily used in two main areas: the production of acetylene gas and organic synthesis. It is a major source of acetylene gas, which finds widespread applications in welding, cutting, lighting, and more. Additionally, calcium carbide serves as a raw material for organic synthesis to produce chemicals like vinyl chloride and synthetic resins.
Q:What are some other uses of calcium carbide?
A:In addition to its primary uses, calcium carbide can be used in oxyacetylene welding, the production of calcium cyanamide for plant growth, and as a desulfurizing agent to reduce sulfur oxide emissions from combustion.
Q:What are the safety precautions for handling calcium carbide?
A: Calcium carbide reacts with water to produce flammable acetylene gas, so careful handling is crucial. Storing and using it should follow safety protocols, keeping away from ignition sources and heat. Additionally, due to the flammable and explosive nature of acetylene gas, appropriate safety measures should be observed during usage.
Q: Where is your plant located?
A: Our calcium carbide factory is situated in Inner Mongolia, in close proximity to the source of carbide raw materials. Spanning across an area of 5000 square meters, our facility boasts a monthly production capacity of 6000 tons.
Q: How can you guarantee the quality?
A: We ensure product quality through several measures. During the carbide processing, we conduct multiple sampling tests to ensure products yield good gas output. Regular air pressure tests are performed on drums to ensure tight and safe sealing. Different sizes are stored separately to prevent mixing. Prior to loading, we conduct another sampling test to ensure the loaded goods have accurate weight, sizes, gas output, and quantity. Our carbide production adheres to the Chinese National Standard: GB10665-2004.
Q: What is the gas yield?
A: Typically, the gas yield of the particle size 80-120mm, 50-80mm, 25-50mm is 295L/KG.
