等静压HL1灰兰釉的研制与应用

介绍了等静压HL1灰兰釉的性能、研制过程、应用情况及生产中质量问题的解决。该釉呈灰兰色,釉面光亮、针孔少、无析晶现象;釉的高温流动度、软化温度等与现行坯料相匹配,与现行烧成工艺相适应;上釉瓷强度比无釉瓷强度提高17%以上,粘度等釉浆性能指标达到等静压工艺要求,产品质量稳定,弯曲强度有较大裕度,釉色满足订货商的要求。

The Development and Application of HL1 Grey-blue Glaze Used in Cold Isostatic Process

The property of the HL1 grey-blue glaze,its development and usage in production,the solutions to some quality problems are introduced.The grey-blue glaze has a shine surface without crystallization and less pinholes and fluidity at high temperature and meet temperature matched with porcelain body performance in firing.The glazing strength increased by more than 17%.The glaze slur-ry property including viscosity at high temerature and meeting temperature.meets the need of produc-tion in cold isostatic dry pressing.The products with stable quality and higher strength have the color required by the customers.
