A study on deformation and filtration properties of a leather semi-finished product after chrome tanning are presented. The analytical dependences of compressive load on compressive (recovery) strain and moisture content of a leather semi-finished product are obtained. The empirical dependences of hydraulic gradient on filtration rates are determined for various compression ratios of the leather semi-finished product. It was revealed that with an increase in compressive load and moisture content of the leather semi-finished product, the compressive deformation increases. The shoulder section is subject to the greatest deformation, then the belly section and the least deformation is observed in the butt section. A linear relationship has been established between the hydraulic gradient and the rate of moisture filtration through the leather semi-finished product in the directions perpendicular and parallel to its surface.

皮革半成品的应变和过滤特性建模

介绍了一种皮革半成品铬鞣后变形和过滤性能的研究。获得了压缩载荷对皮革半成品的压缩(恢复)应变和水分含量的分析依赖性。对于皮革半成品的各种压缩比,确定了水力梯度对过滤速率的经验依赖性。结果表明,随着皮革半成品的压缩载荷和水分含量的增加,压缩变形增加。肩部变形最大,其次是腹部,臀部变形最小。
