From Raw Calcium Carbide to Customized Delivery At KEDE Chemical, we transform high-purity calcium carbide into precisely graded products tailored to industrial applications. Every step is engineered for consistency, safety, and global export standards.
High-quality calcium carbide blocks are sourced directly from controlled furnace production, with each batch verified for purity and gas yield.
Incoming materials undergo initial inspection to ensure compliance with internal quality standards before processing.
Carbide blocks are crushed under controlled conditions to prevent contamination and minimize moisture exposure.
Advanced sieving systems classify material into customized particle sizes according to client specifications.
Particle size distribution and key parameters are rechecked to ensure consistency before packaging.
Qualified material is filled into heavy-duty steel drums with strict weight control and handling procedures.
All drums are nitrogen-flushed, hermetically sealed, and moisture-proof protected to ensure safety and product stability.
Flexible packaging and loading solutions are provided, with optimized container loading for safe and efficient international shipment.
Quality is not inspected at the end — it is controlled throughout the entire process.
* Raw material inspection (CaC₂ purity & gas yield)
* Particle size distribution analysis
* Moisture content control
* Impurity control (PH₃ & H₂S content monitoring)
* Drum sealing integrity checks
* Pre-shipment inspection
To ensure safe and stable acetylene generation, special attention is given to the control of harmful trace gases such as phosphine (PH₃) and hydrogen sulfide (H₂S), minimizing impurities that may affect downstream applications.
Our production complies with international standards to ensure stable performance in acetylene generation, steelmaking, and chemical synthesis.
With stable supply capacity, professional handling, and export-grade packaging, KEDE Chemical ensures your calcium carbide arrives safely and performs reliably — every time.
