| Résumé : |
The relationship between the single technological parameter and chrome absorptivity [percentage of total chrome absorbed] based on laboratory tests and process manual data was studied. Stepwise regression analysis was employed to obtain the quantitative correlation between tanning parameters and chrome absorptivity, on the basis of establishing a relationship between multi-process parameters and comprehensive factors of chromium binding capacity using commercial tanneries actual measurements as contrast. The results showed that, the quantitative calculation of chrome absorptivity through technological parameters could absolutely reflect the actual situation in the tanning process amongst the multiple steps in the heterogeneous and mixed systems contained in the leather making processes. |
