供應三級棕剛玉 地坪棕剛玉金剛砂 Brown fused alumina
棕剛玉性質：
棕剛玉具有純度高，結晶好，流動性強，線膨脹系數低，耐腐蝕的特點。經數十傢耐火生產企業實踐驗證，該產品在應用過程中具有不起爆、不粉化、不開裂的特點。尤其是其遠高於傳統棕剛玉的性價比，更使之成為棕剛玉質耐火材料的最佳骨料和填充料。
產品粒度按國際標準以及各國標準生產，可按用戶要求粒度進行加工。通用粒度號為F4-F320，其化學成份視粒度大小而不同。突出的特點是晶體尺寸小耐沖擊，因用自磨機加工破碎，顆粒多為球狀顆粒，銳石牌棕剛玉具有純度高，質地致密，堆積密度大，自銳性強，韌性好，磁性物含量特低的特點，用其制成的磨具磨削鋒利，發熱率低，磨削比高，且使用時沾附少；制成的燒結磨具具有燒成後顏色深藍、不起網狀裂紋、無銹斑的特點，適用於制造陶瓷、樹脂高固結磨具以及研磨、拋光等。
棕剛玉生產工藝：
第一步：將礬土，鐵屑，無煙煤，按比例混合；
第二步：準備石墨電療（產生高溫高壓的電弧）；
第三步：將原材料加入電弧爐中，原料在電弧爐中經2250℃以上高溫精煉制成棕剛玉；
第四步：經過數小時的高溫冶煉後，傾倒出棕剛玉；
第五步：將容器中的棕剛玉冷去；
第六步：將棕剛玉塊放入制砂機中，生產出棕剛玉段砂；
棕剛玉段砂：
具有介殼狀斷口，邊角鋒利，可在不斷粉碎分級中形成新的棱角和邊刃，使其研磨能力優於其他磨料，尤其是具有硬度高，比重大，化學性質穩定和特有的自銳性等優點，使之成為噴砂工藝用磨料的首選，同時更是噴砂除銹清理工件，研磨拋光的理想材料。
棕剛玉段砂的應用范圍：
1 工件材質，噴砂目的工藝要求
2 不銹鋼表麵去污，除焊渣及亞光效果
3 鐵質工件去銹、除污、除氧化皮、增大鍍層、塗層附著力。
4 鋁制工件 去氧化皮、表麵強化、光飾作用。
5 銅質工件 去氧化皮 亞光效果。
6 玻璃制品 水晶、磨砂、刻圖案。
7 塑膠制品（硬木制品）亞光效果。
8 牛仔佈等特殊麵料、毛絨加工及效果圖案。

The use of the brown fused alumina
Brown fused alumina is mainly used in refractory materials, grinding wheel, sand blasting.
1. Sandblasting, Brown fused alumina‘s hardness is moderate, the bulk density is high,good
toughness.So brown fused alumina is the ideal "environmental protection" type sand blasting
materials, widely used in aluminum, copper material, glass, jeans, precision molds and other
fields;
2. Grinding - used in tube, optical glass, monocrystalline silicon, glass, crystal glass lens,
clock, jade and other products of free grinding,it is an advanced grinding materials in China.
3. Abrasive - The abrasive tool that brown fused alumina production has the color appropriate,
good hardness and toughness, suitable particle cross section type and keeping degree blade, it used in resin abrasive, ideal effect;
4. Abrasive abrasive, abrasive abrasive paper, gauze and other manufacturers of production
materials;
5. Brown fused alumina packing, can be used as building highway pavement, airport runway, docks,
car parks, industrial floor, wear-resisting material such as sports venues;
6. Filtering material - is the application field of brown fused alumina, the underlying medium
using granular grinding, purify drinking water or wastewater, is a new type of water filtration
materials at home and abroad, especially suitable for non-ferrous metal processing, oil drilling
mud weighting agent.
7. Hydraulic cutting - use brown corundum as cutting medium, rely on high pressure water jet
cutting, and applied in the oil (gas) pipe, steel components, such as cutting, is a new type,
environmental protection, safe way of cutting.
