Carbide Chemicals

Used in the production of acetylene gas, polyvinyl chloride, lime nitrogen, dicyandiamide, iron and steel desulfurizer, etc., used in electronics industry, teaching reagents. Calcium carbide is used for chemical production accounts for about 60%, and the remaining 40% is used for metal welding and cutting. Using calcium carbide as raw material can produce a series of chemical products, such as PVC resin, polyvinyl alcohol, vinyl acetate, neoprene rubber, butanol, octanol, tricyanoethylene, tetracyanoethylene, acetaldehyde, acetylene carbon black, lime nitrogen, etc.

Calcium carbide is an inorganic compound, white crystal, industrial products are gray black blocks, cross-section purple or gray. It reacts violently with water, forming acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding and so on. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas when met water, it can burn when meets fire. 4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%). 1.The main raw material for producing acetylene gas. 2.Cutting and welding for metal material. synthesize polyvinyl chloride(PVC). 4.Fruit catalyst. 5.The basic material for organic synthesis and calcium cyanamide 6.Reacting with water to bring about ethine. 7. Reacting with nitrogen to product lime nitrogen. 8.The desulfurizer in steel industry.

CAS 7647-01-0 HS code 28061000 Hydrogen Chloride, HCL Specialty Gas Application Packaged hydrogen chloride (HCl) is used in a range of industries and applications including: Chemicals: To promote and regenerate catalysts in the petrochemical industry and to add viscosity to oils. Also used for hydrochlorinations, e.g. production of methyl chloride, oxichlorinations and vinyl chloride. Hydrogen chloride is also used to produce sulfuric chlorohydrins, synthetic rubbers, etc. Electronics: High purity gas is widely used in the electronics industry. It is a chlorine carrier produced by high temperature cracking. Applications: scouring furnaces (quartz chambers), dissolved in water as an aqueous cleaning agent to prepare metal surfaces for electro plating, selective etching of windows in electronic microcircuits and carrier for non-volatile elements in the form of gaseous chloride. Food & Beverages: To remove the remaining fibres from cotton seeds after the cotton wool has been separated and before the seed is stored for re-sowing next season and also to separate cotton from wood. Steel & Metals: Used in the production of hard metal. Pharma & Biotechnology: Used in pharmaceutical synthesis. 1.Electronic grade usage: It is mainly used for gas phase polishing, epitaxial base corrosion and carbide manufacturing of single crystal silicon in semiconductor device production. 2.Chemical grade usage: Pharmaceutical intermediates, food and feed additives, chemical reagents and film developers and other fine chemicals manufacturing industry. 3.Industrial grade usage: Synthesis of pesticide intermediates, feed additives, chemical reagents and other fine chemicals

CAS : 75-20-7 HS Code : 2849100000 Packing : Grey/Black/Green/Blue/Yellow Iron Drums 305/ 295 /285L/Kg Application Other name: calcium acetylide, acetylene calcium carbide, GA Shape: white crystal, industrial products for black lumps, purple or grey section Partical size avaliable: 2-4mm, 4-7mm,7-15mm, 15-25mm, 25-50mm, 50-80mm, 80-120mm Gas yield: 210L/KG,230L/KG,260L/KG, 295L/KG according different partical size Physical and chemical characteristics: the ore is a solid brown or black solid, pure white crystal products(including CaC2 is purple).Density of 2.22g/cubic centimeter,melting point of 2300 degrees C(with CaC2 content),in case of water immediately produce a violent reaction, the formation of acetylene, and the release of heat, calcium carbide content of different melting point will also change. Calcium carbide (CaC2) is a pivotal inorganic compound known for its industrial form as gray-black block-like material, often displaying purple or gray cross-sections. When exposed to water, it undergoes an energetic reaction, producing acetylene gas and releasing heat. Primarily, it's employed for two key purposes: as a source of acetylene gas with applications in welding, cutting, and fuel, and as a raw material in organic synthesis for chemicals like vinyl chloride and synthetic resins.

Nickel is a hard, ductile and ferromagnetic metal that is highly polished and resistant to corrosion. Nickel is a ferrophilic element. The core is mainly composed of iron and nickel elements. In the crust, iron-mafic rocks contain more nickel than silico-alumina rocks. For example, peridotite contains 1,000 times more nickel than granite, and gabbro contains 80 times more nickel than granite. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer released the preliminary list of carcinogens for reference. Nickel compounds are in the list of carcinogens, metal cobalt, metal nickel and 66-67% nickel, 13-16% nickel. Chromium and 7% iron alloy powders for implantation of foreign bodies in vivo, nickel metal and nickel alloys are on the list of Class 2B carcinogens. Niclkel powder is mainly used in atomic energy industry, conductive materials, battery electrode materials, chemical catalysts, hard surface spray welding, special welding rods, porous filter materials, magnetic materials, contact materials, Diamond tools, automobile manufacturing, cemented carbide, high-temperature high-strength alloys and other powder metallurgy fields.
