Calcium Carbide 15-25 MM Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 C (3,990 F).It is a chemical compound with the chemical formula of CaC2.Its main use industrially is in the production of acetylene, calcium cyanamide, steelmaking, carbide lamps. Calcium Carbide Stones Calcium carbide stones are available in different types of sizes and grades. This calcium product is widely used in various industries such as metallurgy and chemistry. Calcium carbide stone is mostly gray and brown in color. It reacts only with metal oxides without adversely affecting steel chemistry. Info Shape: white crystals, black lumps, purple or gray cross-section for industrial products Available particle size: 1-4mm, 4-7mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, 80-120mm. Gas production: 210L/KG, 230L/KG, 260L/KG, 295L/KG, depending on the size of the particles. Physicochemical Properties: The solid of the ore is brown or black solid, the pure product is white crystal (containing CaC2 is purple). Density 2.22g/cm3, melting point 2300â?? (with CaC2 content), immediately react violently with water to generate acetylene and release heat, calcium carbide content of different melting point will also change. Uses Mainly used in the production of acetylene gas. Also used in organic synthesis, oxyacetylene welding. Calcium carbide reacts with water to generate acetylene can be used to synthesize many organic compounds, such as synthetic rubber, synthetic resins, acetone, vinyl ketone, carbon black and so on. Calcium carbide powder and nitrogen heating, the reaction generated calcium cyanamide, that is, lime nitrogen, cyanide salt and lime nitrogen heating and melting reaction, used in gold mining and non-ferrous metal industry. Tourmaline itself can be used as a desulfurizer in the iron and steel industry. Produces polyvinyl chloride. Packing: 50kg iron drum or 100kg iron drum packing, 22.5 tons/20'fcl.
Abrasives are substances both natural and synthetic that are used to grind, polish, abrade, scour, clean, or otherwise remove solid material usually by rubbing action (as in a grinding wheel), but also by impact (pressure blasting). The most important physical properties of materials that qualify as abrasives are hardness, toughness (or rigidity), grain shape and size, character of fracture (or cleavage), and purity (or uniformity). In the final analysis, the choice of a high-grade abrasive depends upon the quality and quantity of work performed by the abrasive per unit of cost. Initial cost of an artificial abrasive may be much greater than that of a natural abrasive, but the artificial mineral may do so much better work and do it so much faster than the ultimate cost is less. It is for this reason that artificial abrasives have largely replaced natural abrasives. Chemical Properties: Purities are available from PreRish Tri sometimes as high of a typical purity as 99.999% down to low purity recycled abrasive grains or powders Physical Properties: Numerous shape and size options are usually readily available from READE as large as 50 mm grinding and tumbling media down to as small as 20 100 nanometer particles. Typical Applications: Buffing, coated abrasives, coatings, deburring, electrical potting insulation, fillers, fining, flow finishing, friction, grinding wheels, heat transfer component, investment casting molds, wear resistant parts, metal lapping, polishing, pressure blasting, slurry sawing, tumbling, ultrasonic machining.
