Description

高温泡沫过滤陶瓷及制作方法
本发明涉及一种泡沫过滤陶瓷的材料及制作方法。本发明之前，在国内所有稀有金属的高温冶炼熔液过滤都是采用金属材料板过滤，如钛板等。由于金属材料在高温条件下，耐热稳定性、耐热震性、耐化学试剂性、耐腐蚀性、收尘率与粉尘保持量等方面，比高温陶瓷材质要差得多，并且钛钨等金属比高温陶瓷价格要高出几倍。
本发明的目的就是提供一种高温泡沫过滤陶瓷材料及其制作方法，用以替代金属材料在稀有金属的高温冶炼熔液过滤的应用。
本发明的要点。
(1)工艺制作方法是：计量配制→球磨→磁化过筛→抽浆精炼→造浆配制→失模浸浆→脱模干燥→高温煅烧。
(2)重量组份比为：纯度为99％的铝粉75—85，高岭土15—25，水玻璃0.1—1。
其最佳重量组份比为：纯度为99％的铝粉—80，高岭土—20，水玻璃—0.5。
本发明的优点：
(1)能克服金属材料过滤时的不足点，即具有在高温条件下，耐热性稳定，耐热震性，耐化学试剂性，耐腐蚀性强，收尘率与粉尘保持量好。
(2)使用单位能降低成本，并能提高产品质量。
本发明目的由下列实施例予以实现。
第一步：选纯度大于99.0％的d—Al2O3，按重量—80加入重量组份比高岭士—20搅拌均匀放入高铝衬球磨机内用高铝球进行球磨，时间为超过8小时，后用过磁吸设备，再用大于325目筛子过筛，过筛的浆的水份小于30％，再加重量组份比0.5水玻璃进行化浆。把准备好的泡沫失模浸渍在浆内，浸渍时间不能超过1分钟，取出放在120度的干燥设备中干燥脱模4小时，干燥的坯体含水份小于3％，再用达标的坯体装入高温炉在1600度进行24小时煅烧，冷却后包装出厂。

Claims (2)

1、用纯度为99％的铝粉、高岭土、水玻璃，经计量配制→球磨→磁化过筛→抽浆精炼→造浆配制→失模浸浆→脱模干燥→高温煅烧等工艺方法制配的高温泡沫过滤陶瓷，其特征在于重量组份比为：纯度为99％的铝粉75—85、高岭土15—20、水0.1-1；其最佳重量组份比为：纯度为99％的铝粉—80、高岭土—20、水玻璃0.5。
2、根据权利1所述的高温泡沫过滤陶瓷，其特征在于经球磨后，进行磁化，用大于325目的筛子过筛，加水玻璃进行化浆，再用失模浸浆，取出后放在120度的干燥设备中干燥脱模3—6小时定型，然后置于1500—1700℃的高温炉中煅烧20—30小时，冷却后则可。
