Preparation method of silicon oxynitride ceramic riser tube
The invention provides a preparation method of a silicon oxynitride ceramic riser tube, which comprises the following steps: selecting ingredients, adding the ingredients into a stirring mill, and carrying out ball milling for 22-26 hours to prepare uniform ceramic slurry; aging and defoaming the prepared ceramic slurry for 22-26 hours, and performing spray drying through a spray drying tower to prepare ceramic powder conforming to grain size distribution; aging the prepared ceramic powder for more than 48 hours, homogenizing for 30 minutes by using a homogenizer, and adding a forming additive; sintering the ceramic powder into a ceramic silicon oxynitride riser tube; the sintered silicon oxynitride riser tube is machined to the designed size through a grinding machine, and the silicon oxynitride riser tube is packaged and put in storage after being detected to be qualified. According to the preparation method of the silicon oxynitride ceramic riser tube, provided by the invention, the breaking strength of the riser tube reaches about 400-500 MPa by optimizing a formula, sintering, ball milling and forming processes, so that the requirements of domestic ceramic riser tubes can be completely met.
本发明提供一种氮氧化硅陶瓷升液管制备方法，所述制备方法包括：选取配料，将配料加入搅拌磨，球磨22至26小时，制成均匀的陶瓷浆料；将制成的陶瓷浆料经过陈腐，脱泡22至26小时，并通过喷雾干燥塔喷雾干燥，制成符合粒度级配的陶瓷粉料；将制成好的陶瓷粉料进过48小时以上的陈腐以后，使用均化器均化30分钟，添加成型添加剂；将陶瓷粉料烧结成陶瓷的氮氧化硅升液管；采用磨床将烧好的氮氧化硅升液管加工到设计尺寸，检测合格后包装入库；本发明提供的氮氧化硅陶瓷升液管制备方法，通过优化配方，优化烧结、球磨、成型工艺，使得升液管的抗折强度达到400—500兆帕左右，完全能够满足国内陶瓷升液管的需求。
