1. Product Overview
Calcium Carbide 20–40 mm is a large-size granular grade designed for industrial applications requiring slow, controlled reaction and long-lasting gas generation.
Compared to smaller sizes, this grade provides a significantly slower reaction rate, ensuring maximum operational safety and stable performance, making it ideal for large-scale acetylene generation systems and continuous industrial processes.
2. Core Advantages
Slow and Controlled Reaction
Ensures gradual acetylene release, suitable for long-duration operations
Maximum Operational Safety
Minimizes the risk of rapid gas generation, pressure spikes, and overheating
Extended Reaction Time
Larger particle size allows sustained and stable gas production
Robust Handling Performance
Low dust generation and strong physical structure improve storage and transportation safety
