棕刚玉主成分是氧化铝,分等级也就用铝含量来区分, 铝含量越低也就硬度越低了。
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~F320,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,因用自磨机 加工破碎,颗粒多为球状颗粒,表面干洁,易于结合剂结合。
使用范围棕刚玉称作工业的牙齿:主要用在耐火材料,砂轮,喷砂 。
1.喷砂棕刚玉——喷砂磨料硬度适中,堆积密度高,无游离二氧化硅,比重大,韧性好,奥凯棕刚玉是理想的“环保”型喷砂材料,广泛应用于铝型材,铜型材玻璃,水洗牛仔服精密模具等领域;
2.自由研磨——研磨级磨料,应用于显像管、光学玻璃、单晶硅、镜片、钟表用玻璃、水晶玻璃、玉器等领域的自由研磨,是国内普遍采用的高级研磨材料;
3.树脂磨具——磨料具有颜色合适、硬度好、有韧性、合适的颗粒断面类型和刃口保持度,应用于树脂磨具,效果理想;
4.涂附磨具——磨料是砂纸、纱布等生产厂家的生产原料;
5.棕刚玉功能性填料——主要用于汽车制动件、特种轮胎、特种建筑制品等领可作为修筑高速公路路面、飞机跑道、码头、停车场、工业地坪、体育场地等耐磨材料;
6.过滤介质——是磨料的新型应用领域,采用粒状磨料作过滤床的底层介质,净化饮用水或废水,是国内外新型的水过滤材料,尤其适用于有色金属选矿、石油钻井泥浆加重剂:
7. 磨料水力切割——是以磨料作切割介质,依靠高压水力射流进行基本切割,应用于石油(天然气)管道、钢材等部件的切割,是一种新型、环保、安全的切割方式。客户群:水洗厂牛仔喷砂车间造船厂修船厂钢结构厂微粉厂砂轮厂砂纸,砂布厂水晶玻璃行业建筑地坪业钢铁业五金业电子业汔车制造业海岸码头,停车场医院体育场.喷砂行业等合作满足于各类用户所需地坪骨料和磨料。

Brown aluminium oxide
With bauxite, carbon material, iron filings as raw materials, Brown Fused Alumina is restored and obtained through the melting of the brown the brownartificial corundumin the furnace above 2200 ℃, and made of a variety of particle sizes products by purifying, crystallization, sorting, crushing, magnetic separation and screening methods. With its dense texture, high hardness and the formation of spherical particles, it is suitable for the manufacture of ceramics and resin, as well as the high-Bonded Abrasives grinding, polishing, sand blasting, precision casting and so on, also can be used to manufacture high-grade refractory material.
Brown Fused Alumina has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant and other characteristics. Dozens of refractory manufacturers have proved in practice that the product has not detonate, non-powder, non-cracking characteristics in the application process.
Particle size is in accordance with international standards and can be processed as requirements. Universal size: No. F4 ~ F320, its chemical composition varies depending on grain size. Its prominent feature is the small crystal size, impact resistance and spherical particles. This product has high purity, dense texture, large bulk density, strong self-sharpening, good toughness, low level magnetic material content and other characteristics.
