Description

Technical Field

[0001] The utility model relates to the technical field of plate liquid recovery, and in particular to a plate liquid circulation recovery and processing device for green printing. Background Art

[0002] Fountain solution is an indispensable chemical additive in the printing process of color printing machines. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of the ink on the image into the blank part and prevent dirty plates. Offset printing realizes the transfer of images based on the principle of "oil and water are immiscible". In actual printing, in order to keep the blank part of the printing plate hydrophilic, prevent the ink from diffusing into the blank part, and ensure the balance of water and ink on the printing plate, fountain solution is needed. However, since the fountain solution is recycled, during the printing process, ink, paper powder, plate washing liquid, etc. will be mixed into the fountain solution, or precipitate or float, and the quality of the fountain solution will be damaged after long-term accumulation. In order to ensure the printing quality, printing companies generally replace the fountain solution once a week. According to calculations, the weekly discharge of fountain solution waste liquid of a four-color printing press is 100kg. Although the discharge of a single machine does not seem large, from the perspective of the entire industry, the pollution caused by these waste liquids to the environment must be taken seriously.
