产品详情

White aluminum oxide powder 7um白刚玉7微米

白刚玉微粉是一种研磨级的电熔氧化铝微粉。硬度高，热稳定性强，耐磨性能好，粒度分布均匀，化学性质稳定，耐火温度高。也广泛应用于耐磨涂料，工业陶瓷等行业。

White aluminum oxide powder 7um is made from high-quality aluminum oxide by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The white alumina produced in titling electric arc furnaces has the advantage of high bulk density and low porosity and good volume stability and thermal shock resistance. As one of the most commonly used corundum in the abrasive industry, White fused alumina has a long history in applications because of its high hardness, good self-sharpening advantages. By adopting high-quality grade materials, a strict quality control system, and developed production technology, HAIXU’s white fused alumina gets high purity, stable quality, and good distribution.

The micro-powder from Haixu Abrasives is acid-washed and gets water pickled, by this process, the white fused alumina powder is with better purity and better grit size distribution.

White aluminum oxide powder 7um白刚玉7微米的特点：

氧化铝纯度高（99.5%以上），因而硬度比较高，磨削力强，研磨效***。

水分工艺生产，粒度更加均匀，无大颗粒，不会***工件表面。

化学稳定性强，对酸碱的承受能力强，不溶于水。

热稳定性强，高温下的耐磨性能不受影响。

白度高，不会影响涂料等制品的颜色。

用途广泛，不仅用于研磨抛光，也可做涂料、陶瓷、橡胶、塑料、复合材料的添加材料。

Characteristic:

The electrofused aluminum oxide powder for polishing has outstanding features including small crystal size, impact resistance. By ensuring the excellent purity, HAIXU Abrasive&＃39;s product works very extraordinary well at sand blasting and raw material for abrasive tools. Users will get a multi-recycle experience and more durable performance.
