什麼是棕剛玉，棕剛玉的成份用途？
棕剛玉以工業氧化鋁粉為原料，於電弧中經2000度以上高溫熔煉製成。棕剛玉主要化學成份是
AL2O3，其含量在98.65％一-99.37%,另含有少量的Fe，Si，Ti等。棕剛玉適用於製造陶瓷、樹脂固
結磨具以及研磨、拋光、噴砂、精密鑄造等，還可用於製造高級耐火材料。
棕剛玉代#“A”於國際通用標準、國家標準一致，多數供出口，也有一定量供應國內用戶。
★噴砂級棕剛玉分為：16#46#60#80#100#120#150#180#200#220#280#
棕剛玉是以優質磨料級礬土為原料，配以輔料，於電弧爐中經2250℃以上高溫精煉製成。其自銳性好、磨削力強。
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#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衝擊，因用自磨機加工破碎，顆粒多為球狀顆
粒，表面干潔，易於結合劑結合。

What is the corundum, corundum ingredients purposes?
Corundum industrial alumina powder as raw materials, in 2000 in arc above high temperature melting. Corundum main chemical compositions
The results indicated that the content of AL2O3, in a 99.37% - contains very little, Fe, Si, Ti, etc. Corundum applies to manufacturing pottery and porcelain resin solid
"Abrasive and grinding, polishing, sandblasting, precision casting, etc, also can be used in the manufacture of high-grade refractory materials.
Corundum generation # "A" international standards and national standards, most for export, also have certain supply domestic users.
U sandblasting level corundum is divided into: 16 # # # # # # # 46 60 # # # 120 80 150 # 100 # # # # # 200 180 220 280 #
Corundum is high grade alumina grinding as raw material, match with complementary makings, in electric arc furnace temperature above model.this 2,250 degrees from refining. Since the sharp and strong force.
According to international standards and product size, but all standard production according to user requirements granularity for machining. General granularity F320 ~ # for F4, depending on the size of the chemical composition and different. Prominent characteristics of crystal size is small, impact resistance with the grinding machine is broken, grain processing, dry clean surface of spherical particles, easy to combine agent.
鞏義 JinHuaNai materials enterprise off-the-shelf lots of corundum.
