Calcium Carbide Lumps 50g

Description

Calcium Carbide is a gray or black solid substance that is commonly used in a variety of industrial applications. Recently, it has gained attention due to its efficiency in generating acetylene gas for various applications, especially in welding and cutting processes. Upon contact with water, it reacts vigorously to produce acetylene gas (C'H') and calcium hydroxide, making it an essential compound not only in welding, metal cutting, but also in several chemical processes.

 Applications:

Acetylene Gas Production

• Welding and Metal Cutting: The primary application of calcium carbide is the production of acetylene gas (C'H') when reacted with water. The recent rise in industrial demands has reaffirmed the importance of acetylene as a fuel in oxyacetylene welding and cutting processes due to its high flame temperature.
• Chemical Industry: Acetylene gas produced from calcium carbide continues to be a critical building block in the chemical industry, leading to the manufacture of various organic chemicals, including vinyl chloride (for PVC), acetaldehyde, acetic acid, and synthetic rubber.

Steelmaking and Metallurgy

• Desulfurization of Steel: Calcium carbide is recognized in the steelmaking industry as a desulfurizing agent. Its reaction with sulfur impurities in molten steel to form calcium sulfide (CaS) has proven beneficial in improving the quality and properties of steel.
• Slag Conditioning: In specialized metallurgical processes, calcium carbide enhances slag conditioning to improve removal of impurities and better control of the chemical composition of molten metal.

Fertilizer Industry

• Calcium Cyanamide Production: It plays a vital role in the production of calcium cyanamide (CaCN'), which is an important nitrogen fertilizer and herbicide. Additionally, it enriches the soil with nitrogen and acts as a weed inhibitor.
• Artificial Ripening of Fruits: In various regions, calcium carbide is employed to accelerate the ripening process of fruits such as bananas, mangoes, and tomatoes. However, its use is often scrutinized due to health concerns regarding potential contaminants.

Chemical Synthesis

• Vinyl Chloride Production: Calcium carbide serves as a precursor to vinyl chloride, which is essential in producing polyvinyl chloride (PVC), a versatile plastic utilized across multiple industries including construction and packaging.
• Other Organic Compounds: Calcium carbide also contributes to the synthesis of various organic chemicals like acrylonitrile, a key material for synthetic fibers and plastics.

Calcium Carbide Lamps (Carbide Lamps)

• Portable Lighting: Traditionally, calcium carbide was widely known for its use in carbide lamps for portable lighting in mining and caving. These lamps channel the acetylene gas produced from calcium carbide reacting with water to create a bright flame. Although largely replaced by modern lighting technologies, carbide lamps are still favored by enthusiasts and certain specialized sectors.

Waste Treatment

• Wastewater Treatment: It has potential applications in treating certain types of industrial wastewater by precipitating impurities and reducing toxic substances.

Petroleum Industry

• Carburization: Occasionally utilized within the petroleum sector for carburization processes, whereby carbon is infused into molten iron or steel, augmenting hardness and strength.

Pyrotechnics and Explosives

• Explosives and Fireworks: Calcium carbide is employed in various pyrotechnic processes when combined with other chemicals, creating memorable effects in fireworks and theatrical presentations.

Environmental and Chemical Remediation

• Gas Generation for Experiments and Demonstrations: In laboratory settings, calcium carbide is frequently used to generate acetylene gas for experimental purposes, enhancing the study of numerous chemical reactions involving gases.
• Chemical Neutralization: In specific remediation strategies, calcium carbide is utilized for neutralizing certain chemical wastes, demonstrating its versatility beyond industrial applications.

Storage and Handling:

• Store in dry, airtight containers to prevent moisture contact, as its reaction with water leads to the production of flammable acetylene gas.
• Keep in a cool, well-ventilated environment free from heat sources, moisture, and incompatible materials like acids or oxidizers.
• Adhere to proper fire safety measures due to the high flammability of acetylene gas.

Safety Information:

• Hazard Class: Dangerous when wet (4.3)
• UN Number:
• Personal Protective Equipment (PPE): Wearing gloves, goggles, and protective clothing is highly recommended when handling calcium carbide.
