0-1 1-3 3-5mm 白刚玉粒度砂 白刚玉磨料
白刚玉
中文名称：白刚玉
英文名称：white fused alumina
定义：人造磨料的一种。三氧化二铝(Al2O3)含量在98％以上，并含有少量氧化铁、氧化硅等成分，呈白色。
产品简介
白刚玉 以工业氧化铝粉为原料，于电弧中经2000度以上高温熔炼后冷却制成，经粉碎 整形，磁选去铁，筛分成多种粒度，其质地致密、硬度高，粒形成尖角状，适用于制造陶 瓷、树脂固结磨具以及研磨、抛光、喷砂、精密铸造等，还可用于制造高级耐火材料 ，代号“WA”于国际通用标准、国家标准一致，多数供出口，也有一定量供应国内用户。
产品粒度按国际标准以及各国标准生产，可按用户要求粒度进行加工。通用粒度号为 F4~F220，其化学成份视粒度大小而不同。突出的特点是晶体尺寸小耐冲击，如果用自磨机 加工破碎，颗粒多为球状颗粒，表面干洁，易于结合剂结合。
白刚玉磨料级优点：
⒈不影响加工件的颜色；
⒉可在严禁铁粉残留的制程使用来喷砂；
⒊微粉级非常适合湿式喷砂和研光作业；
⒋加工速度快品质高；
⒌所含氧化铁的量极低适合严禁铁质残留之喷砂作业；
⒍经过酸洗步骤以除杂质。

Chinese name: white corundum
English name: white fused product
Definition: a kind of artificial abrasives. 3 oxidation 2 aluminium (Al2O3) content over 98%, and contains a small amount of ferric oxide, silicon oxide, such as composition, white.
Product introduction
White corundum using industrial alumina powder as raw materials, regularly above 2000 degrees high temperature smelting in electric arc made after cooling, the grinding plastic, magnetic separation to iron, screen is pided into a variety of particle size, dense texture, high hardness, particle formation Angle shape, is suitable for manufacturing ceramic porcelain, resin consolidation abrasive and grinding, polishing, sand blasting, precision casting, etc., can also be used for manufacturing high-grade refractory materials, codenamed "WA" international general standards, national standards, most for export, also has a certain supply of domestic users.
Product size according to the international standards and national standards production, processing granularity according to users requirement. Gm grain sizes for the F4 ~ F220, its chemical composition depending on the size of the particle size. Outstanding characteristic is little impact resistance, crystal size, if use the broken mill processing, particles are spherical particles, the surface dry clean, easy to bond together.
White corundum abrasive level advantages:
does not affect the color of the machined part; 2. Can be used in iron powder residue is forbidden of process to sand blasting; 3. Grade micro powder is very suitable for wet sandblasting and research the light; 4. High processing speed quality; ⒌ very low amount of iron oxide in suitable for the sand blasting of iron residue is strictly prohibited; 6. After pickling process to impurities.
White fused alumina chemical indicators and physical indicators:
