Calcium carbide boasts a multitude of specific applications, integral to various industrial processes:
1.Acetylene Gas Production: Renowned for its pivotal role, calcium carbide is a primary progenitor of acetylene gas. The chemical reaction of calcium carbide with water is a cornerstone process that results in the generation of acetylene gas. This gas is indispensable across multiple industries, finding extensive application in welding, cutting, and metal processing. Additionally, it serves critical functions in lighting and heating solutions.
2.Organic Synthesis: As a foundational raw material in chemistry, calcium carbide is harnessed in the synthesis of a broad spectrum of organic compounds. It plays a vital role in the manufacturing of essential products such as vinyl chloride, chloroprene rubber, synthetic resins, and more, underscoring its versatility and industrial importance.
3.Oxyacetylene Welding: The acetylene gas derived from calcium carbide, when combined with oxygen, becomes a powerful tool in oxyacetylene welding. This method is widely employed in metal welding and cutting operations, demonstrating the compound's critical importance in industrial metalworking.
4.Calcium Cyanamide Production: In another significant application, calcium carbide is utilized to produce calcium cyanamide, which serves as a chemical fertilizer essential for enhancing plant growth, thus contributing to the agricultural sector.
5.Desulfurizing Agent: Within certain industries, calcium carbide plays a crucial role as a desulfurizing agent. It is instrumental in minimizing sulfur oxide emissions resultant from combustion processes, thereby supporting environmental sustainability.
Please Note:Given the inherent properties of calcium carbide, particularly its proclivity to generate acetylene gas upon exposure to water, it is paramount to ensure that its applications comply with stringent safety and environmental standards, safeguarding both users and the ecosystem.
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.
