Calcium Carbide – Essential Acetylene Generator for Metal Cutting, Synthesis & Ripening
We supply industrial-grade Calcium Carbide (CaC₂) in standard lump or granular forms. This reactive chemical compound is the primary source for on-site acetylene gas generation. Consequently, industries actively use it for metal cutting and welding, chemical synthesis, and as a fruit ripening agent. Moreover, its ability to produce a hot, concentrated flame and serve as a chemical building block makes it fundamental to welding shops and process industries.
Core Applications for Calcium Carbide in Industry & Agriculture
This compound serves distinct, high-value roles in metal fabrication, chemistry, and controlled agriculture. Its applications are based on its vigorous reaction with water.
First, the metal fabrication and welding industry relies on calcium carbide for acetylene gas production in portable generators. This gas, when combined with oxygen, creates the high-temperature flame essential for metal cutting, welding, and brazing. Therefore, workshops and construction sites without cylinder gas access depend on it for critical metalwork.
Second, the chemical manufacturing sector utilizes the acetylene derived from it as a key feedstock for producing organic chemicals like vinyl chloride, acetaldehyde, and synthetic rubber. Furthermore, in a controlled agricultural context, it is used in small quantities as an ethylene gas generator for ripening fruits like bananas and mangoes post-harvest.
Critical Specifications for Calcium Carbide (CaC₂)
We produce our calcium carbide to meet standard industry specifications for gas yield and particle size. Thus, users can expect consistent acetylene generation for their welding or chemical processes.
