Additional Information

電池隔膜耐磨填料白剛玉微粉W2.5

電池隔膜耐磨填料白剛玉微粉W2.5的特點：

氧化鋁純度高（99.5%以上），因而硬度比較高，磨削力強，研磨效率高。

水分工藝生產(chǎn)，粒度更加均勻，無大顆粒，不會劃算工件表面。

化學穩(wěn)定性強，對酸堿的承受能力強，不溶于水。

熱穩(wěn)定性強，高溫下的耐磨性能不受影響。

白度高，不會影響涂料等制品的顏色。

用途廣泛，不僅用于研磨拋光，也可做涂料、陶瓷、橡膠、塑料、復(fù)合材料的添加材料。

Product Feature of white fused aluminum oxide powder

The Al2O3 purity is high(99%min). So the hardness grinding ability is high with good grinding efficiency.

High wear-resistance. Even in high-temperature circumstances, the strength is still excellent.

The white fused aluminum oxide powder is suspension-treated by water. So it is of flowability and easy to scatter.

Low oil absorption especially for water-based paint.

Neutral property with PH value around 7-8.

High whiteness. It doesn’t affect the color of paints or coatings adding Al2O3 powder.

Resistant to most corrosive alkali and acid. It doesn’t dissolve in water.

Resistant to high temperature up to 1900 °C.

Good particle size consistency without big-size grains. So it prevents scratches on the grinding substrate.
