Study on the Reduction Treatment of ink Sludge in Flexo Printing

The paper studied about the characteristics of ink sludge of flexo printing and analyzed the possibility different reduction treatment and disposal. Industrial analysis and elemental analysis to confirm the elemental content, TGA and DTG were used to analyze the weight loss and heat absorption and desorption behavior of dry sludge at different temperature. GC-MS and XRF analysis was applied to analysis the composition and content of the compounds. Three kinds treatment for for ink sludge based on different needs.
