| Abstract | Flexographic printing plates contact solvents in the process of their production and operation: washing solvents and printing paint components. As a results of such contact plates swell. Swelling changes polymers’ elastic properties of which the plate is made, changes the scan point sizes that, in the final analysis, affects the printing product quality. The kinetics of swelling flexographic plate polymer interaction with low-molecular liquids used in the process of plate production and operation was studied. Constants of speed, parameters Flory - Huggins, diffusion coefficient D for each solvent was determined. The changes of the basic thermodynamic functions ΔG, ΔS, ΔH of swelling, are calculated. The received data allow to choose the optimum solvents for processes of polygraphic technology. |
