品牌鞏義市明悅剛玉制品有限公司 型號bfa-1 種類黑剛玉 規(guī)格16-320目 材質al2o3 粒度16-320目 適用范圍噴砂拋光耐火材料 展開 5%含量黑剛玉 黑剛玉人造磨料 明悅黑剛玉工效高 點我去除廣告 【黑剛玉簡介】 明悅黑剛玉的主要含量是三氧化二鋁70-80%左右，因而具有硬度適中、韌性高、耐高溫、熱態(tài)性能溫定的特點。黑剛玉又名低鋁剛玉，是于電弧爐中，將鋁礬土熔煉而制得的一種以α-al2o3和鐵尖晶石為主礦相的灰黑色結晶體，其特點是al2o3含量較低，并有一定量的fe2o3（10%左右）存在，因而具有硬底適中、韌性高、耐高溫、熱態(tài)性能溫定的特點。多用于自由研磨，如制品電鍍前的打磨工粗磨，主要用于不銹鋼，金屬制品，光學玻璃。 black corundum 3 oxidation 2 aluminium is the main content of 70-80%, thus has moderate hardness, high toughness, high temperature resistant, thermal steady state performance characteristics. 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 grinder coarse grinding products before plating, it is mainly used for stainless steel, metal products, optical glass. 【黑剛玉性能】 黑剛玉的冶煉方法與棕剛玉相同，是以三水鋁礬土為原料，加少量還原劑，經溶煉而成，其耗電量約為棕剛玉的三分之二。呈黑色，三方晶體，主要化學成分：al2o3不低于77%，sio2含量為10~12%，fe2o3含量為7~10%，tio2約為3%，比重不小于3.61。硬度：莫氏9.0，熔點：2050℃，真密度＞3.50g/cm3。線膨脹系數（0-1600°）：7-9。使用溫度：1850℃。 明悅黑剛玉具有很好的自銳性，磨削時發(fā)熱量少，加工件的光潔度較好，適用于零件電鍍前底面拋光，鋁制品和不銹鋼的拋光，也可用于拋光光學玻璃、加工木材等。由于它的親水性好，可用在制造砂紙、砂布和樹脂磨具，還可以作研磨膏和拋光粉。黑剛玉由于鐵含量高，因而不宜用于制造陶瓷磨具。 black corundum smelting method is the same as the brown fused alumina, in sanshui bauxite as raw material, add a small amount of reducing agent, the smelting, its power consumption is about two-thirds of the brown fused alumina. in black ink, the three crystal, the main chemical composition: not less than 77% al2o3, sio2 content of 10-12%, fe2o3 content of 7 ~ 10%, tio2 is about 3%, the proportion of not less than 3.61. hardness: morse 9.0, melting point: 2050 ℃, true density > 3.50 g/cm3. the linear expansion coefficient (0-1600 °) : 7-9. temperature: 1850 ℃. black corundum has the very good self-sharpening, calorific value, less when grinding roughness of machined part is good, suitable for the floor polishing, prior to the plating aluminum and stainless steel polishing, also can be used for polishing of optical glass, wood processing, etc. because of its good hydrophilicity, can be used in manufacturing sandpaper, emery cloth, and resin abrasive, still can make grinding paste and polishing powder. black corundum due to their high iron content, and therefore should not be used in the manufacture of ceramic grinding tool. 【黑剛玉指標】 規(guī)格 主要化學成分 al2o3 fe2o3 sio2 一級 85 9 ≤6 二級 80 10 ≤10 項目 指標 顏色 黑色 晶型 三方晶系 硬度（莫氏） ≧9.0 熔點（℃） 2050 使用溫度（℃） 1850 真密度（g/cm3） ≧3.5 【黑剛玉用途】 明悅黑剛玉磨料多用于自由研磨，如制品電鍍前的打磨工粗磨，主要用于不銹鋼，金屬制品，光學玻璃，竹木制品的拋光和噴砂，又是制造樹脂砂輪，切割片，紗布的新穎磨料。本公司黑剛玉磨料基本粒集中，切削力強，韌性大，剛柔相濟，耐磨性好，工效高。是磨削拋光、噴砂不銹鋼制品的理想產品。 1、自由研磨，如金屬零件電鍍前底面拋光、鋁制品。 2、自行車、摩托車、縫紉機、鐘表零部件。 3、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）。 4、加工材料、制造樹脂切割片、角磨片和涂附磨具等。 5、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。 6、黑剛玉段砂更是防滑路面和煤礦坑下倉儲的材料。 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. the company black corundum abrasive basic particle concentration, strong cutting force, tenacity is big, and flexibility, good abrasion resistance, high working efficiency. grinding polishing, sandblasting stainless steel products is the ideal product. 1, freedom, grinding, such as floor polishing before plating metal parts, aluminum products. 2, bicycle, motorcycle, sewing machine, clock parts. 3, lamp act the role ofing, plastic and hardware tools, such as polishing, is also suitable for sandblasting (spray derusting, glass flower). 4, processing and manufacturing resin cutting, angle grinding pills and coated abrasive, etc. 5, black corundum sand granularity and micro powder particularly suitable for grinding and polishing of stainless steel workpieces and sharpening stone, grinding paste manufacturing. 6, black corundum sand antiskid pavement and coal mine under storage material of choice. 【聯系方式】 鞏義市明悅剛玉制品有限公司 銷售經理：張玉霞 聯系電話：13014515629 q q：3175186955 地 址：鞏義市永安路外溝村 gongyi city mingyue corundum products co., ltd sales manager: yu-xia zhang contact phone number: 13014515629 q q: 3175186955 address: gongyi city wing road outside ditch village
