Preparation method of high-compactness zirconia ceramic microspheres
The invention discloses a preparation method of high-compactness zirconia ceramic microspheres. The preparation method comprises the following steps: step 1, preparing materials; 5, the zirconium oxide slurry is injected into an injector with a specific caliber, an outlet of the injector is connected with a multi-mesh spray head through a hose, the zirconium oxide slurry is pushed into liquid paraffin which rotates at a high speed and is mixed with a certain proportion of catalyst at the rotating speed of 250-400 r/min, the water bath temperature of the liquid paraffin is 50 DEG C, sprayed zirconium oxide slurry liquid drops are automatically pelletized under the action of centrifugal force, and the zirconium oxide slurry is obtained. Carrying out polymerization reaction in liquid paraffin, and instantly curing into balls; the slurry is pushed into liquid paraffin which rotates at a high speed and is mixed with a certain proportion of catalyst at a certain speed through the multi-mesh spray head, so that the retention time of the slurry in the thrust device is shortened, a reaction system is prevented from reacting in advance, and the utilization rate and the production efficiency of the slurry are improved.
本发明公开了一种高致密性的氧化锆陶瓷微球的制备方法，包括以下步骤：步骤1：材料准备；步骤5：将氧化锆浆料加注到特定口径的注射器中，注射器出口用软管连接多网眼的喷头，以转速为250‑400r/min速度推入高速旋转的混有一定比例催化剂的液体石蜡中，液体石蜡水浴温度50℃，喷出的氧化锆浆料液滴在离心力的作用下自动成球，并且在液体石蜡中发生聚合反应，瞬间固化成球；本发明通过本发明通过多网眼的喷头，以一定速度推入高速旋转的混有一定比例催化剂的液体石蜡中，缩短浆料在推力装置的停留时间，防止反应体系提前反应，提高了浆料的利用率和生产效率。
