寧波市玻璃制品磨面噴砂用黑剛玉

黑剛玉簡介

黑剛玉又名低鋁剛玉，三氧化二鋁(Al2O3)含量為70%～80%，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(jié)晶體，其特點是Al2O3 含量較低，并有一定量的Fe2O3（10%左右）存在，因而具有硬度適中、韌性高、耐高溫、熱態(tài)性能溫定硬度適中、其韌性較大耐磨棱角鋒利、自銳性強、磨削是發(fā)熱量少、拋光加工工件潔度高、切削力強、剛?cè)嵯酀�、耐磨性好、工效高的特點。

Black corundum and low aluminum corundum, 3 oxidation 2 aluminium (Al2O3) content is 70% ~ 70%, 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%), thus has moderate hardness, high toughness, high temperature resistant, thermal state performance steady moderate hardness, its toughness is larger wear-resisting, self-sharpening sex strong, sharp edges and corners are less calorific value, high pure degree of polishing machining, strong cutting force, the characteristics of flexibility, good wear resistance, high working efficiency.

黑剛玉含較多的氧化硅和氧化鈦等雜質(zhì)，呈黑色的一種剛玉。在磨料產(chǎn)品中，棕剛玉、白剛玉、黑剛玉同樣都是以鋁礬土為主要原料，加有鐵屑在高溫電弧爐中熔煉而成的，為什么黑剛玉的價格在其中是較低的呢，在市場上鋁的價格比鐵的價格每噸要高出好多，棕剛玉一級砂的三氧二化鋁的含量在95%以上，而黑剛玉一級砂的三氧二化鋁含量才達到85%，在此就可以看出黑剛玉的原因了。

Black corundum contains more silicon oxide and titanium oxide and other impurities, is a kind of black corundum. In abrasive products, corundum, white corundum, black corundum is same bauxite as main raw materials, with iron filings in the high temperature electric arc furnace smelting, and why the black corundum price is the lowest, in which the aluminum in the market price is the price of iron per ton higher lot, brown corundum sand level three oxygen two aluminum content is above 95%, and the black corundum sand level of three oxygen two aluminum content to reach 85%, in which can see the black corundum prices low.

黑剛玉特點

黑剛玉品硬度適中，韌性較大耐磨棱角鋒利，自銳性強，拋光加工工件潔度高，其拋光性能大大高于國內(nèi)外其他同類產(chǎn)品，廣泛應用于餐具行業(yè)，電鍍行業(yè)，金屬表面處理行業(yè)，玻璃制品行業(yè)。

Black corundum products moderate hardness, toughness big wear-resisting sharp edges and corners, since the sharpness is strong, high pure degree of polishing machining, the polishing performance much higher than other similar products at home and abroad, is widely used in tableware industry, electroplating industry, metal surface treatment industry, glass industry.

黑剛玉的冶煉方式基本上和棕剛玉的冶煉生產(chǎn)方法一樣。黑剛玉的生產(chǎn)方法是選用優(yōu)質(zhì)鋁礬土、氧化鐵等原材料，添加其它微量元素，經(jīng)傾倒式電弧爐精心冶煉，保證了冶煉出的塊狀黑剛玉全為一級品，雜質(zhì)少、品位高、質(zhì)量穩(wěn)定。為生產(chǎn)硬度適中、韌性好，使用性能優(yōu)良穩(wěn)定的段砂、粒度砂和微粉奠定了基礎(chǔ)。

Black corundum smelting method basically and brown fused alumina smelting production methods. Black corundum production method is to choose the high quality bauxite, iron oxide, such as raw material, add other trace elements, by the dumping of electric arc furnace smelting carefully, to ensure the smelting of massive black corundum all for one, less impurity, high grade and stable quality. For producing moderate hardness and toughness, good use of high performance and stable period of sand, sand particle size, and micro powder laid a foundation.

黑剛玉用途

黑剛玉用于自由研磨，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。本公司黑剛玉黑剛玉磨料基本粒集中，切削力強，韌性大，剛?cè)嵯酀�，耐磨性好，工效高。是磨削拋光、噴砂不銹鋼制品的較理想產(chǎn)品。

Black corundum used for grinding freedom, like 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, black corundum abrasive basic particle concentration, strong cutting force, tenacity is big, and flexibility, good abrasion resistance, high working efficiency. Grinding polishing, sandblasting of stainless steel products is the most ideal products.

黑剛玉段砂特別適合做高速公路、機場跑道、大橋路面等的耐磨防滑材料，適合做耐磨防滑地坪材料。各規(guī)格粒度砂粒度分布集中，公司內(nèi)控指標高于國標，是優(yōu)質(zhì)的拋光研磨材料。具有硬度適中，韌性、自銳性、粘結(jié)性良好，經(jīng)久耐用等特點。磨削時發(fā)熱量小，不易劃傷工件表面，不易引起工件表面變色，加工后工件表面光潔度高、色差極小。主要用于金屬工件等研磨拋光，特別適合于不銹鋼工件的研磨拋光，亦適用于光學玻璃、木材等材料的拋光，也大量用于制成樹脂磨具，砂帶等涂附磨具。溫縣明陽機械設(shè)備制造分廠長期供應優(yōu)質(zhì)棕剛玉、白剛玉、黑碳化硅、石英砂、核桃殼、玉米芯、黑剛玉、脫硫劑、地坪金剛砂、除銹砂、金剛砂、鋼丸、鐵砂、鋼絲切丸等產(chǎn)品。

Black corundum sand is particularly suitable for high-speed road, airport runway, the wear-resisting of antiskid material such as bridge pavement, suitable for making wear non-slip floor material. Each specification size grain size distribution, the company internal control index is higher than the national standard, is the high quality of polishing abrasive materials. With moderate hardness, toughness, self-sharpening, good bonding, durability and other characteristics. When the grinding heat is small, not easy to scratch the surface, not easy to cause surface discoloration, processed workpiece surface roughness is high, the color difference. Is mainly used for metal artifacts such as grinding and polishing, especially suitable for grinding and polishing stainless steel workpieces, apply to polishing optics glass, wood and other materials, also used to make various resin abrasive, abrasive belt such as coated abrasive tool.County MingYang machinery manufacture factory long-term supply of high quality brown corundum, white corundum, black silicon carbide, quartz sand, walnut shell, corn cob, black corundum, desulfurizer, floor emery, rust removing sand, emery, steel shot, iron ore, steel cut wire shot, etc.

名稱:金剛砂主題詞或關(guān)鍵詞:材料科學內(nèi)容1891年，美國人阿切遜將粘土和焦炭混合后放在一個鐵缽中，企圖用電弧將碳轉(zhuǎn)化為金剛石。但結(jié)果是，在電極附近發(fā)現(xiàn)了閃閃發(fā)光的六方形晶體，它與天然金剛石的立方八面體不同。阿切遜認為這可能是碳和粘土中的氧化鋁反應而生成的新化合物。由于自然界中有一種氧化鋁礦物稱為剛玉，于是他把碳和剛玉兩個英文單詞連起來作為這一新化合物的名稱，中國學者將其譯成“金剛砂”。后來人們知道這種化合物是由粘土中的二氧化硅與碳在高溫下反應生成的碳化硅。晶胞為面心立方結(jié)構(gòu)，每個晶胞含有4個C原子4個Si原子。與金剛石結(jié)構(gòu)類似。碳化硅硬度僅次于金剛石、碳化硼和立方氮化硼，在無機材料中排行第四。目前已能通過熱壓燒結(jié)法制得高致密度的碳化硅。它具有很高的強度及良好的抗氧化性能，在高溫下不變形，可作為高溫燃氣輪機上的渦輪葉片，也可作耐磨的密封材料，還可作火箭尾噴管的噴嘴及輕質(zhì)的防彈用品等金剛砂，SiC，學名碳化硅。純的是無色晶體。密度3.06～3.20。硬度很大，大約是莫氏9度。一般的是無色粉狀顆粒。磨碎以后，可以作研磨粉，可制擦光紙，又可制磨輪和砥石的摩擦表面。由砂和適量的碳放在電爐中加強熱制得。天然金剛砂又名石榴子石，系硅酸鹽類礦物。經(jīng)過水力分選，機械加工，篩選分級等方法制成的研磨材料。生產(chǎn)使用歷史悠久，古代我國就有使用金剛砂研磨水晶玻璃，各種玉石的史例。十九世紀四十年代又遠銷東洋。分粗目，中目，細目三大類。其中粗目為黑紅色，中目為淡紅色，細目為紅白色，各種目數(shù)粒度均勻，顆粒形狀均一，成棱叫角晶體，有鋒利的邊緣，磨削力高。供石材類工業(yè)研磨大理石及其它軟質(zhì)材料。玻璃類工業(yè)研磨玻璃毛邊，電視機顯像管，光學器械，鏡片，棱鏡，鐘表用玻璃等。金屬類工業(yè)噴砂，除銹，研磨。印刷工業(yè)研磨膠版，以及輕工業(yè)加工塑樣，皮革，砂紙等用途。天然金剛砂的磨削力略低于電爐白剛玉，但其任性強，具有介殼狀段口之特性，其優(yōu)點是磨件的光潔度高，砂痕少而淺。磨面細而均勻，可提高產(chǎn)品質(zhì)量，為本品的獨特之處。天然金剛砂的研磨時間短，效益高，價格低廉，可彌補壽命短的不足。
