Calcium carbide, is an inorganic compound, the chemical formula is CaC2, is the main component of calcium carbide, for white crystalline powder, industrial products for gray-black lump, cross-section purple or gray.
We are Tianjin Zhongying Chemical, a direct factory supplier in China. We supply high purity calcium carbide for global industrial acetylene gas production. Calcium acetylide is a key chemical raw material for industrial applications. First, our modern Inner Mongolia factory produces high grade calcium carbide lumps under strict quality control. Therefore, we deliver stable gas yield performance and pure quality for your chemical processing plant.
Our industrial calcium carbide meets international manufacturing standards. According to PubChem chemical safety databases, calcium carbide reacts rapidly with water to produce flammable acetylene gas. First, we offer various particle sizes including 1-4mm, 4-7mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, and 80-120mm lump sizes. Second, our products provide accurate gas yield options of 210L per kg, 230L per kg, 260L per kg, and 295L per kg. As a result, your gas plant achieves high efficiency in daily operations.
Global buyers choose our calcium carbide for many heavy industrial processes:
Acetylene Gas Generation: First, factories use it to generate pure acetylene gas for industrial cutting and oxyacetylene welding.
Chemical Processing: Second, chemical plants apply it to synthesize polyvinyl chloride PVC, synthetic rubber, acetone, and carbon black.
Steelmaking Desulfurization: Third, foundry mills use powdered calcium carbide as an effective steel desulfurizer agent. You can also inspect our caustic soda flake 99 for other chemical needs.
Metal Mining Industry: Fourth, plants process it with nitrogen to produce lime nitrogen for nonferrous metal mining.
In addition, our dark grey and black lump carbide features high density of 2.22 grams per cubic centimeter. Consequently, the high chemical purity ensures fast dissolution and strong reaction in gas equipment.
Safe ocean transport requires strong moisture proof containers for bulk cargo shipping:
50KG Iron Drum Package: First, we pack high quality lumps into sealed 50kg steel drums for flexible handling.
100KG Iron Drum Package: Second, we supply durable 100kg iron drums with sealed rubber gaskets for long distance ocean transit.
Container Capacity: Third, we load up to 22.5 metric tons per 20 foot full container load.
Shipping Documents: Fourth, we provide complete COA, SDS, and Certificate of Origin for smooth customs clearance.
In addition, every steel drum uses heavy duty nitrogen filling to stop air moisture ingress. Consequently, our safe packaging protects product safety during sea freight transit effectively.
Are you a direct calcium carbide factory or a trading company? First, we are a direct manufacturer. Second, we operate our primary production plant in Inner Mongolia and manage large export warehouses near Tianjin Port.
Which particle size is best for acetylene gas plants? First, the 25-50mm and 50-80mm lump sizes are most popular for standard acetylene gas generators. Second, smaller 1-4mm and 4-7mm granules work best for special chemical synthesis.
Do you provide quality certificates per shipment? Yes, we test every production batch. First, we issue official COA and gas yield test reports before container loading at the port.
What are your terms of payment for export orders? First, we accept flexible payment terms for global buyers. For example, we accept TT payment, 100 percent LC at sight, and DP terms.
Do you need to buy high yield calcium carbide at factory prices? Contact our export management team right now via WhatsApp or email. First, we will answer your inquiry within 1 hour. Second, we will provide direct FOB or CIF price quotes immediately.
