Production process of high-purity spherical aluminum oxide for display glass
The invention provides a production process of high-purity ball-like aluminum oxide for display glass, and belongs to the technical field of aluminum oxide. Putting the mixed aluminum oxide powder into a ball mill for ball milling to obtain relatively uniform particle size distribution; gathering the ball-milled aluminum oxide powder into relatively uniform particle groups through a wet granulation or dry granulation process; carrying out screening and particle selection on the granulated particle groups so as to control the particle size distribution of the obtained spherical aluminum oxide; the sieved particle groups pass through drying equipment to remove moisture in the particle groups, so that the particle groups have certain fluidity; molding the dried particle groups through pressing or injection molding equipment according to requirements, so as to obtain spherical aluminum oxide with a required shape; putting the formed spherical aluminum oxide into a sintering furnace, and carrying out high-temperature sintering treatment, so that particles of the spherical aluminum oxide are combined into hard aluminum oxide particles at high temperature; cooling is performed; performing screening; and packaging.
本发明提供显示玻璃用高纯类球型氧化铝生产工艺，属于氧化铝技术领域，包括以下步骤：原料准备；将混合的氧化铝粉末放入球磨机中进行球磨，以获得较为均匀的颗粒粒径分布；将球磨后的氧化铝粉末通过湿法制粒或干法制粒工艺，将其聚集成较为均匀的颗粒团；对制粒后的颗粒团进行筛分和选粒，以控制所得球型氧化铝的粒度分布；将筛分后的颗粒团通过烘干设备，去除其中的水分，使其具备一定的流动性；将烘干后的颗粒团按照需求通过压制或注射成型设备进行成型，得到所需形状的球型氧化铝；将成型后的球型氧化铝放入烧结炉中，进行高温烧结处理，使其颗粒在高温下结合成坚硬的氧化铝颗粒；冷却；筛分；包装。
