Abstract
PURPOSE: To regenerate paint from waste thinner discharged from the washing processes, by separating the waste thinner to the filtrate and the filtration residue with a thinner recovering device, and effectively utilizing the filtrate as the solvent component of a rust preventive paint and the filtration residue as the resin component of a chip-resistant paint.
CONSTITUTION: For example, the waste thinner 2 (pref. ≤20% solid content) discharged from the washing process and stored in the tank 1, is sucked with a pump 3, and introduced into the line 5 by slowly opening the by-pass valve 4. The flow rate is measured by the flow meter 6 equipped in the line 5, and controlled to generate the pressure difference (P1-P2) of 2W3kg/cm2 before and after the module 7 (pref. a module passing the component having a molecular weight of ≤1,000). The filtration residue which is not concentrated by the module 7 is returned to the tank 1 through the heat exchanber 8, and the filtrate passed through the artificial membrane of the module 7 is stored in the thinner tank 9. The above cycle is repeated to regenerate the paint.
