Polishing techniques for glass
玻璃经过粗磨细磨后其表面仍属于细的“毛面”,需要抛光才能使玻璃变成透明光洁的表面,经过粗磨料研磨的玻璃再用抛光材料进行抛光,可以使玻璃明亮而具有光泽。
抛光的方法我司主要采用机械抛光。
常用的抛光材料包含红粉(氧化铁),氧化铈,氧化铬,氧化钍氧化锆等。日用玻璃加工也有使用长石粉的。
影响玻璃机械抛光过程的主要工艺因素包含:抛光材料的性质,浓度和给料量,抛光盘的压力和转速,周围环境的温度和玻璃温度,抛光盘的材质,抛光悬浮液的性质,玻璃抛光机使用时化学过程与机械过程的匹配度。
其中抛光盘的材质一般使用毛毡,硬沥青,无纺布,还有聚氨酯,聚四氟乙烯等有机材料。光学玻璃抛光球面与非球面透镜时,用尼龙铝,锌等薄片之外侧覆盖薄沥青层的柔性抛光盘,这种抛光盘沿着被加工工件表面始终与之保持吻合状态,此外采用同浸渍氧化铈的发泡氨基甲酸酯抛光盘,可实现高速抛光,粗毛毡或半羊毛毡的抛光效率高,细毛毡和尼龙的抛光效率低,玻璃制品表面深刻,常用粗磨和细磨再进行抛光。
