Calcium carbide is endowed with several specific utilities, and here are its principal applications:
1.Acetylene Gas Production: Calcium carbide stands as a predominant source of acetylene gas. Once calcium carbide is introduced to water, the resulting reaction produces acetylene gas, which is indispensable in the realms of welding, cutting, and metal processing, in addition to being employed in lighting and heating applications.
2.Organic Synthesis: As a pivotal chemical raw material, calcium carbide is utilized in the fabrication of diverse organic compounds. It plays a critical role in the synthesis of vinyl chloride, chloroprene rubber, synthetic resins, and a multitude of other compounds.
3.Oxyacetylene Welding: The acetylene gas derived from calcium carbide, when combined with oxygen, becomes an essential element in oxyacetylene welding, a technique widely applied in metal welding and cutting across various industries.
4.Calcium Cyanamide Production: Calcium carbide also finds its use in the production of calcium cyanamide, a highly effective chemical fertilizer that boosts plant growth.
5.Desulfurizing Agent: In certain industrial settings, calcium carbide serves as a proficient desulfurizing agent, effectively aiding in the reduction of sulfur oxide emissions generated during combustion processes.
Please Note:It is crucial to understand that, due to the inherent properties of calcium carbide, particularly its proclivity to produce acetylene gas upon contact with water, its applications must strictly comply with established safety and environmental regulations.
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.
