本文以粉体等静压制实践为依据,着重介绍黄培云双对数粉体压制方程的推广应用。认为通过数学处理可将该式变化为非对数形式 11种粉体等静压制实验数据验证表明,上式精度较高(D_(c计)/D_(c实)=1±0.01),具有实用价值。文中对该式进行了解析,指出上式即为粉体等静压制的压制压力——压坯密度曲线的数学表达式且其斜率为
Based on the practice of powder isostatic pressing, this article focuses on the popularization and application of the double logarithmic powder compacting equation of Huang Peiyun. It is considered that this equation can be changed to a non-logarithmic form through mathematical treatment. The verification of the isostatic compaction experimental data of 11 kinds of powders shows that the above formula has high precision (D c (c) / D c (real) = 1 ± 0.01) Practical value. In this paper, the formula is analyzed, pointing out that the above formula is the powder isostatic pressing pressure - the mathematical expression of compact density curve and the slope of
