Product Description

 High hardness and abrasion resistant black corundum sand used for sandblasting of plastic parts

Black corundum profile


Black corundum is black, micro - colored solid particles is a new type of polishing materials.Black corundum and low aluminum corundum, is in electric arc furnace, the bauxite made by melting a is given priority to with alpha Al2O3 and spinel mineral phase of the colored crystals, its characteristic is Al2O3 content is lower, and has a certain amount of Fe2O3 (10%), and thus has a hard bottom is moderate, high toughness, high temperature resistant, the characteristics of the thermal state performance is steady.More for free grinding, such as the beat of the products before electroplating grinder coarse grinding, it is mainly used for stainless steel, metal products, optical glass, bamboo and wood products polishing and sanding, making resin grinding wheel, cutting slices, gauze of new abrasive.

 

Black corundum performance characteristics
Black corundum sand hardness is moderate, the toughness is bigger wear-resisting sharp edges and corners, the sharpness is strong, grinding is less calorific value, high pure degree of polishing machining, the polishing performance much higher than other similar products at home and abroad, the aluminum content is greater than 82% black corundum, high hardness and great toughness and flexibility, wear-resisting and durable;The caking property and good hydrophilicity, facilitate the mill;When grinding block less, less heat, workpiece will not burn;Since the sharpness is strong, high efficiency, no scratches, and processing, cast high finish;More than double higher than that of brown fused alumina polishing ability, finish improve 2 above.

Black corundum purposes
Black corundum abrasives suitable for stainless steel, aluminum, metal plating before floor polishing and sanding, polishing and 2.5 times higher than that of other abrasive efficiency, bright and clean degree increased by 1.5 times.At present, the most widely used in stainless steel kitchen utensils and appliances, lighting lamps and lanterns of motorcycle parts, auto parts and other medium hardness materials fine polishing, also used in grinding of freedom.It also applies to products such as glass, wood, stone grinding and polishing, making resin grinding wheel, emery cloth of novel materials.
