　　黑剛玉簡介：Black corundum profile

　　黑剛玉又名低鋁剛玉、青剛玉，是于電弧爐中，將鋁礬土熔煉而制得的一種AL2O3和鐵尖晶石為主礦相的灰黑色結(jié)晶體，其特點是AL2O3含量較低，并有一定量的Fe2O3(10%)存在，因而具有硬度適中、韌性大、自銳性、粘結(jié)性良好，耐用度高，磨削時發(fā)熱少，耐高溫，不易劃傷工件表面，工件表面光潔度高等特點。

　　Black corundum and low aluminum corundum, blue corundum, is in electric arc furnace, the bauxite made by melting a AL2O3 spinel is given priority to with iron ore phase of the colored crystals, its characteristic is AL2O3 content is lower, and has a certain amount of Fe2O3 (10%), and therefore, moderate hardness and great toughness, self-sharpening, good bonding, high durability, produce less heat when grinding, high temperature resistant, not easy to scratch the surface of the workpiece surface roughness is high.

　　黑剛玉用途：Black corundum purposes

　　黑剛玉主要應(yīng)用于自由研磨，如金屬零件電鍍前底面拋光、鋁制品，適用于自行車、摩托車、縫紉機、鐘表零部件、燈飾、塑膠及五金工具等的拋光，亦適用于噴砂(除銹、玻璃噴花)，加工材料，制造樹脂切割片、角磨片和涂附磨具等。黑剛玉粒度砂和微粉特別適合于不銹鋼工件的研磨拋光及油石、研磨膏的制造，黑剛玉段砂更是防滑路面和煤礦坑下倉儲的首選材料。

　　Black corundum is mainly used in free grinding, such as floor polishing before plating metal parts, aluminum products, suitable for bicycle, motorcycle, sewing machine, clock parts, lamp act the role ofing, plastic and hardware tools, such as polishing, is also suitable for sandblasting (spray derusting, glass flower), materials processing, manufacturing resin cutting, Angle grinding pills and coated abrasive, etc.Black corundum sand granularity and micro powder particularly suitable for grinding and polishing of stainless steel workpieces and sharpening stone, grinding paste, black corundum sand antiskid pavement and coal mine under the storage and the material of choice.
