Welcome to Tianjin Zhongying Chemical Co., Ltd., your world-class manufacturing partner for optimizing the generation of acetylene from calcium carbide. Backed by our massive, state-of-the-art production base in Inner Mongolia—China's prime region for high-purity limestone and coke resources—we specialize in supplying premium-grade Calcium Carbide (CaC₂) stones that serve as the critical foundation for high-efficiency acetylene gas production across the globe.

Optimize Industrial Efficiency: High-Purity Acetylene Generation
For major industrial consumers, the efficiency of generating acetylene from calcium carbide dictates overall operational profitability. Whether your enterprise utilizes acetylene for heavy-duty metal welding, steel cutting, chemical synthesis, or specialized agricultural fruit ripening, the chemical stability of your raw material is paramount.

Our specialized calcium carbide line is engineered to deliver unmatched performance:
Maximized Gas Yield: We guarantee a stable and superior gas yield of ≥295L/KG. This high conversion rate ensures that you extract the maximum volume of pure acetylene from calcium carbide, significantly reducing raw material waste and lowering your processing costs.
Controlled Reaction and Particle Sizes: To suit different types of acetylene gas generators, we offer precision-screened sizes including 25-50MM and 50-80MM for steady gas release, alongside other options from 4-7MM to 80-120MM.
Strict Moisture-Proof Packaging: To ensure zero pre-reaction during long-term maritime shipping, our products are tightly sealed in brand-new 50kg or 100kg steel drums, available with customized colors and private labeling.
