jing yuan electronic technology co., ltd., zhengzhou is a professional flat alumina polishing powder (wta series specifications) production, research and development and sales of technology-based manufacturer. with the international advanced production lines and first-class staff, with coulter multisizer ⅱ-type particle size analyzer, and other sophisticated quality control equipment. products are mainly used for grinding and polishing silicon wafers, compound semiconductor materials, optical glass, crt glass, high-grade display glass, crystal, fine ceramics, special metal surface.
产品概述summarize
wta--平板状氧化铝研磨微粉(platelet calcined alumina)是以硬质的高温α-al2o原料,经过粉碎、精密粒度分级制成,硬度仅次于金刚石,是非常优异的精密研磨微粉。
being excellent precision abrasive and lapping micro-powder,twa(platelet calcined alumina),which is only softer than diamond,is made by hard and high-temerature α-al2o3 as raw material after being shattered and precide particle size distribution.
特征 earmark
1.非常设计的粒度分布,可得到高精度的被加工表面,无划伤。
2.微粉颗粒特有的平板状结构,保证研磨高效率。
1.precisely particle size distribution makes a precision processed surface without any scratch.
