| 摘 要： | 采用机械破碎造粒、喷雾造粒及离心造粒等三种方法制得的粉料颗粒,制备出高温密封元件,借助于形貌分析、性能分析等手段,发现离心造粒方法获得的颗粒圆球度、密度和强度最好,能满足密封元件破碎后颗粒自身状态和分散状态的要求,以实现有效密封。

| Abstract: | The manual crushed granulation,spray granulation and centrifugal granulation methods were chosen to produce the granule for the preparation process of a seal material applied under high-temperature.Assisted with the microscopy observation and performance analysis,the centrifugal granulation method was found the best one among the three methods with regards to roundness,bulk density and strength of the granule produced.The effective seal can be fulfilled by the seal element which shows the excellent shape,size,size distribution and integrity of the granule. |
