Spotlight on 25-50mm Calcium Carbide – The Preferred Choice
Among our product range, the 25-50mm calcium carbide size is one of our most popular offerings. This particle size is engineered for optimal performance in industrial applications, offering the perfect balance between controlled reaction rate and ease of handling.
Key Applications of 25-50mm Calcium Carbide:
Acetylene Gas Production – The primary and most important use of calcium carbide. When reacted with water, 25-50mm calcium carbide generates acetylene gas with a yield of 295–300 L/kg, making it ideal for oxy-acetylene welding, cutting, and metal fabrication.
PVC Manufacturing – Acetylene derived from calcium carbide is a critical raw material for producing polyvinyl chloride (PVC), vinyl chloride monomer, and other synthetic polymers.
Steel Industry Desulfurization – Our 25-50mm calcium carbide serves as an effective desulfurizing and deoxidizing agent in iron and steel production, improving metal quality and corrosion resistance.
Chemical Synthesis – Used in the production of calcium cyanamide (a nitrogen fertilizer), dicyandiamide, acetic acid, acetaldehyde, and other organic chemicals.
Fruit Ripening Catalyst – In certain agricultural applications, calcium carbide is used as a ripening agent for fruits.
Packaging & Container Specifications – Tailored to Your Needs
For our 25-50mm calcium carbide for sale, we offer flexible and secure packaging options designed to protect product integrity during transit and storage. All drums are made of new, heavy-gauge steel with airtight seals to prevent moisture ingress – a critical requirement for calcium carbide.
Standard Packaging Options:
| Package Type | Net Weight per Drum | Drums per 20' Container | Total Net Weight |
|---|---|---|---|
| 50kg Iron Drum | 50 kg | 450 drums | 22.5 tons |
| 100kg Iron Drum | 100 kg | 225 drums | 22.5 tons |
Our 20-foot container loading capacity is precisely 22.5 metric tons net weight, whether you choose 50kg drums (450 drums per container) or 100kg drums (225 drums per container). For larger orders, 40-foot containers can accommodate up to 25 metric tons.
All packaging complies with UN regulations for dangerous goods (UN 1402, Class 4.3) and is designed to withstand the rigors of international shipping. We also offer palletized and non-palletized loading options based on your preference.
