生产耐火材料级白刚玉磨料级白刚玉白刚玉细粉

白刚玉简述：

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。

白刚玉适用于制造陶瓷、树脂固结磨具以及研磨、抛光、喷砂、精密铸造（精铸专用刚玉）等，还可用于制造耐火材料，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。

white corundum in industrial aluminum oxide powder as raw material, to the arc by high temperature above 2000 degrees of melting cooling made by crushing, plastic, magnetic separation to iron, sieve into a variety of size, its dense texture, high hardness, sharp particle formation.

white corundum is suitable for the manufacture of ceramics, resin bonded abrasives and grinding, polishing, sandblasting, precision casting (casting special corundum), also can be used in the manufacture of high-grade refractory materials, code-named "wa" to international standards, national standards, mostly for export, also has a fixed supply of domestic users.

particle size of products according to international standards and national standards of production, according to user requirements for processing granularity. universal size: no. f4~f220, its chemical composition varies depending on grain size. the prominent feature is the small crystal size, impact resistance, if broken from the processing mill, particles as spherical particles, surface clean, easy to bond with.

白刚玉化学指标和物理指标：

化学指标		物理指标
al2o3	≥99.5％	努普硬度	2000-2200kg/mm2
fe2o3	≤0.4％	莫氏硬度	9
na2o	≤0.22％	堆积密度	1.75-1.95g/cm3
sio2	≤0.04％	真密度	3.9-4.9g/cm3

白刚玉密度：

密度分为两种，一是白刚玉堆积密度，二是白刚玉真密度。　　

堆积密度为：1.53~1.99g/cm3，磨料的堆积密度与磨料的粒度，粒度组成，品种，颗粒形状等因素都有关，一般来说，粗粒度磨料比细粒度磨料堆积密度大，混合粒度磨料的堆积密度大于单一的粒度密度。　　

颗粒密度为：3.95~4.0g/cm3，精铸专用刚玉真密度4.1g/cm3，磨料的真密度是指单位体积（排除开气孔的体积）内所含磨料的质量。　　

基本粒度为：45%~55% ，基本粒度是保证研磨效果的重要指标，在生产时应可以适当控制，但生产速度可能放缓。

density is divided into two kinds, one is the white corundum bulk density, true density is two white corundum.

bulk density: 1.53~1.99g/cm3, abrasive density and abrasive particle size, particle size composition, species, are related, particle shape factor in general, coarse-grained abrasive than fine-grained abrasive high packing density, mixed size abrasive bulk density is greater than the particle density single.

particle density: 3.95~4.0g/cm3, casting special corundum 4.1g/cm3 true density, real density of abrasive and refers to the unit volume (excluding open pore volume)contained within the abrasive quality.

basic size: 45%~55%, the basic size is important index to ensure the grinding effect, in the production should be properly controlled, but the production rate may slow.
