Calcium Carbide 80-120MM
Calcium Carbide china 80-120MM, a large-size industrial-grade product with particle diameter strictly controlled between 80mm and 120mm, is classified into three main categories based on purity, gas yield, and application scenarios, ensuring targeted supply for different industrial needs. All categories comply with international standards (UN No. 1402, HS Code 284910) and adopt moisture-proof packaging to maintain product stability.
The first category is Industrial Grade Calcium Carbide china 80-120MM, with a CAC₂ purity of 80%-85% and a gas yield of ≥295L/kg. It features low powder content and stable reactivity, mainly used in large-scale acetylene gas generation, heavy chemical manufacturing, and metal welding/cutting. This category is cost-effective, suitable for bulk industrial use and international export projects requiring basic stable performance.
The second category is High-Purity Grade Calcium Carbide china 80-120MM, with CAC₂ purity ≥90% and gas yield ≥315L/kg. It has ultra-low impurities (PH₃ ≤0.04%, H₂S ≤0.06%) and is optimized for high-demand scenarios such as precision chemical synthesis, PVC production, and high-quality steel desulfurization, meeting stricter quality standards than national benchmarks.
The third category is Agricultural & Special Grade Calcium Carbide china 80-120MM, with moderate purity (85%-90%) and controlled reaction rate. It is mainly used in calcium cyanamide production (a nitrogen fertilizer) and outdoor acetylene lighting, leveraging its large particle size to reduce dust and ensure safe, long-lasting reaction. All categories are packaged in 50kg/100kg steel drums or jumbo bags, suitable for long-distance sea freight and bulk transportation.
