负离子材料对骨质瓷坯料性能的影响

Effect of Negative Ion Material on the Properties of Bone China Blank

将负离子粉,电气石和麦饭石作为负离子材料分别加入骨质瓷坯料中,研究负离子材料对骨质瓷坯料性能的影响规律,确定负离子材料的种类与添加量。结果表明:在骨质瓷坯料泥浆中加入负离子材料能够使骨质瓷坯料泥浆相对粘度和触变性增大,比重变小。麦饭石对样品的烧成收缩的影响最明显。负离子材料的添加量增加,样品的负离子释放量增大,添加负离子粉的样品最为明显。负离子材料影响骨质瓷白度,添加量越多白度降低越明显;在添加量相同的情况下,加入负离子粉的样品白度更高。在骨质瓷坯料中加入负离子材料能够使施釉后烧成的骨质瓷成品仍然具有负离子释放能力。

Negative ion powder,tourmaline and medical stone were added in bone china blank. The effect of negative ion materials on the properties of bone china were discussed,and the negative ion materials and the addition were confirmed. Studying the influence of negative ion materials on the relative viscosity,thixotropy and gravity of slurry when added several negative ion materials to bone china glaze,the experimental results showed that the relative viscosity and thixotropy increased and the gravity decreased. It was obvious that medical stone caused firing shrinkage of the products. The electronegative ion realeasing concentration of the products increased when the addition of negative ion materials increased,and the influence of negative ion powder was most obvious. Whiteness of the products gradually decreased when the addition of negative ion materials. At the same negative ion materials content,the whiteness of the products which was added to negative ion powder was higher. When to bone china glaze were added several negative ion materials can release negative ions after glaze.
