Product description

Calcium carbide (CaC₂) is a multifaceted chemical compound with various industrial applications. Its primary use is in the production of acetylene gas (C₂H₂) through a reaction with water, which serves as a crucial component in welding, cutting metals, and synthesizing organic chemicals. Additionally, calcium carbide plays a significant role in the agriculture sector by producing lime nitrogen fertilizers essential for plant growth. In steel manufacturing, it is utilized as a desulfurizing agent to enhance steel quality. Furthermore, acetylene is instrumental in the production of polyvinyl chloride (PVC) plastics, widely employed in various applications such as piping and wire insulation. The diverse uses of calcium carbide underscore its importance across multiple industrial sectors.

Calcium Carbide, with the chemical formula CaC₂, is an incredibly versatile industrial chemical that has been a cornerstone in various industries worldwide. Its diverse applications make it a highly sought - after product for global procurement.

1. Acetylene Gas Production

One of the most traditional and widespread uses of Calcium Carbide is in the production of acetylene gas (C₂H₂). When Calcium Carbide reacts with water, it produces acetylene gas. In the metalworking industry, acetylene gas is a staple for welding and cutting metals. According to industry reports, over 60% of small - to - medium - sized metal fabrication shops rely on acetylene gas for their daily operations. Additionally, acetylene serves as a crucial chemical raw material for numerous downstream processes.

2. Organic Chemical Synthesis

Acetylene gas, derived from Calcium Carbide, is the starting point for many organic synthesis reactions. It is used in the production of plastics, synthetic rubbers, solvents, and other chemicals such as acetylene alcohol and acetylene aldehyde. The global market for plastics produced from acetylene - based processes is expected to reach $20 billion by 2028, highlighting the significant role of Calcium Carbide in this sector.

3. Lime - Nitrogen Fertilizer Production

Calcium Carbide is also used to produce lime nitrogen (calcocyanine), a valuable nitrogen fertilizer. This fertilizer provides the essential nitrogen that plants need for growth. In agricultural regions where soil nitrogen levels are low, lime - nitrogen fertilizers can increase crop yields by up to 30%, making Calcium Carbide an important input in the agricultural supply chain.

4. Steel Production Desulfurizer

In the steel production process, Calcium Carbide acts as an effective desulfurizer. Sulfur in steel can reduce its ductility and toughness, so removing it is crucial for high - quality steel production. By using Calcium Carbide as a desulfurizer, steel manufacturers can achieve sulfur removal rates of up to 90%, improving the overall quality of the steel.

5. PVC Plastics Production

Acetylene gas, obtained from Calcium Carbide, is one of the most important raw materials for the production of polyvinyl chloride (PVC). PVC is widely used in the manufacture of pipes, wire and cable insulation, and many other products. The global PVC market is projected to grow at a CAGR of 4% from 2023 to 2028, indicating a continuous demand for Calcium Carbide in this industry.
