Description

制备色阶陶瓷的方法及渐层浆料混合装置 技术领域
本发明是关于制备色阶陶瓷的方法及渐层浆料混合装置。
背景技术
现有渐层技术中是提供至少二种不同颜色的染色液体(水盐类染色液体)及一陶瓷块体；再将所述染色液体同时且分别由所述陶瓷块体的相对二侧进行一浸泡程序(采用真空浸泡，所述浸泡程序的时间为0.25小时～4小时之间)，使所述陶瓷块体相对二侧分别吸收所述染色液体。浸泡后的陶瓷块体取出并进行一静置程序，所述静置程序的时间为24小时～48小时，静置后的陶瓷块体进行一热干燥程序或一冷冻干燥程序(二择一)，将干燥后的陶瓷块体进行一烧结程序，进而得一包含有至少二色区的陶瓷块体，所述烧结程序是在至少摄氏1450度中烧结至少l小时。但此等技术缺点仍属多重步骤，且制程耗时(需要浸泡、干燥、再烧结)。
目前氧化锆陶瓷材料制作均需经过冷均压成形或热均压烧结成形属较复杂步骤，且制程设备涉及高压，更属高单价仪器需有专业人员操作并非一般人可涉略。此材料须经过高压制作后机械性质改变成极佳，方可被牙科数字加工(CAD/CAM)领域应用，为牙科产业带来许多便利与简化许多传统制作步骤，不过，却也衍生出多项缺点，如制程中，软加工(Soft-matchined)的部分烧结瓷块进行车削后，其体积收缩量大(约有25％的体积收缩)；而硬加工(Hard-matchined)则是所用的瓷块材料硬，成形时间长，对工具耗损大，而且车削过程可能含有裂缝(Crack)产生。除此之外，加工机器、车削工具(Milling tool)、材料均属高单价，此外，车削后的剩余材料不易再利用，进而导致浪费。而瓷块颜色大部分为单一颜色，常造成美观与仿真性不佳的情形。
