【玉神】紫蜡专用α（阿尔法）氧化铝抛光粉

紫蜡专用α氧化铝系列

α-alumina series for purple wax

本系列产品全部采用1500度以上天然气超高温回转窑煅烧，产品原晶为类球型，原晶大，发育完全；本系列产品原料、焙烧温度、原晶完全相同，只是根据要求控制研磨时间，以达到客户所要求的不同粒度等级。

The series are calcined in natural gas rotary kiln with temperature over 1500℃, and the original crystal is spherical, big and fully developed. The raw materials, firing temperatures and crystals of this series are the same. The difference of this series is different grinding durations according to different requirements on particle size.

（1）YF-PA50G-1型，平均粒度8-10um（800目），主要适合生产切削率好的紫蜡，用于不锈钢、不锈铁、碳钢等金属粗抛光，具有极强的切削力和一定光泽度。

（2）YF-PA40G型，平均粒度15-20um（500目），适合生产切削率好的粗抛紫蜡，切削力优于YF-PA50G-2，光度差于YF-PA50G-2。

（3）YF-PA30G，平均粒度为40-55um（200目），是玉发抛光氧化铝切削力**强的一种。适合生产切削率好的粗抛紫蜡，用于除去不锈钢表面的砂眼和氧化层，切削力优于YF-PA40G，光度差于YF-PA40G。

（1）YF-PA50G-1, with the average particle size of 8-10μm (800mesh), is suitable for producing purple wax with good cutting force, which is used to coarse polish metals such as stainless steel, stainless iron and carbon steel. It is featured with excellent cutting force and certain glossiness.

（2）YF-PA40G, with the average particle size of 15-20μm (500mesh), is suitable for producing coarse polishing purple wax with good cutting force. Its cutting force is better than YF-PA50G-2 but its glossiness is worse than YF-PA50G-2.

（3）YF-PA30G, with the average particle size of 40-55μm (200mesh), and the strongest cutting force among the polishing alumina developed by Yufa, is suitable for producing coarse polishing purple wax, which is used to remove the sand explosions and oxidation layer on surface of stainless steel. Its cutting force is better than YF-PA40G, but the glossiness is worse than YF-PA40G.
