Large-specification ceramic plate blank, pressing method thereof and ceramic plate
The invention discloses a large-specification ceramic plate blank, a pressing method thereof and a ceramic plate, and relates to the technical field of pressing forming. The pressing method comprises the following steps: (1) providing ceramic plate powder, and testing the flowability and grading distribution of the ceramic plate powder; (2) distributing the ceramic plate powder into a die cavity formed by a lower die core and a die frame; the ceramic plate powder divides the die cavity into a material distribution cavity and a material upsetting cavity; (3) calculating a required pier material cavity depth H1r and a required pier material cavity depth H1p; and (4) a pressing scheme is determined according to the relationship between the required pier material cavity depth and the pier material cavity depth. By means of the method, exhaust in the pressing process of the large-specification ceramic plate blank can be optimized, the uniformity of the ceramic plate blank is improved, and the occurrence probability of pressing defects is reduced.
本发明公开了一种大规格陶瓷板坯体及其压制方法、陶瓷板，涉及压制成型技术领域。其中，压制方法包括：(1)提供陶瓷板粉料，测试其流动性，级配分布；(2)将所述陶瓷板粉料布料到下模芯、模框所形成的模腔中；陶瓷板粉料将所述模腔划分为布料腔及墩料腔；(3)计算需求墩料腔深度H1r及墩料腔深度H1p；(4)根据需求墩料腔深度与墩料腔深度的关系确定压制方案。实施本发明，可优化大规格陶瓷板坯体压制过程中的排气，提升陶瓷板坯体的均匀性，降低压制缺陷的发生概率。
