| 摘 要： | 在各种温度下,研究初始厚度为0.4mm(±0.03)的YSZ流延膜片薄层热风干燥的一般规律。干燥受风速的影响都较大,风速越高,干燥速度越快;风速越低,干燥速度越慢;在干燥后期,三个不同的风速水平对干燥过程的影响几乎没有明显差异。流延膜片越厚,干燥速度越慢;而流延膜片厚度越小,干燥速度越大;过高的风温风速会使流延膜片性能质量降低;热风干燥的参数必须考虑实际生产中产品的质量要求设定;所求得的Page模型能够正确反映水溶胶胶层薄层干燥规律,可用于实际生产工艺的基础参考数据。

| Abstract: | Hot air drying at various temperatures for the tape-cast YSZ membrane with the initial thickness of 0.4mm(± 0.03) was studied.The influence of airflow rate on drying is remarkable.The higher the airflow rate,the faster the drying;the lower the airflow rate,the slower the drying;rate;in the late stage of drying,the three different airflow rates make almost no drying difference.The thicker the tape cast membrane,the slower the drying;the thinner the membrane,the quicker the drying;the airflow at too high a temperature or too fast a velocity will lower the membrane performance.The setting of the hot-air drying parameters must consider the quality requirements of the actual products.The obtained Page model correctly reflects the drying process of layered hydrosol.It can provide reference for the actual production. |
