During periodic maintenance of printing and post-press machinery, fasteners, metal guards, mechanical parts and various auxiliary components may be removed for inspection or repair. Over time, oil, grease, paper dust, ink residues and residues from previous maintenance products may accumulate on these components. Cleaning the parts prior to inspection, reassembly, painting or the application of protective coatings is an important preparation stage of the maintenance process.
The fundamental principle of degreasing is to dissolve, emulsify or otherwise enable the removal of oily films from metal surfaces using a suitable chemical system. For localized maintenance applications, industrial cleaners with degreasing properties or suitable solvent-based cleaning systems may be used. In more systematic metal surface preparation processes, alkaline degreasing methods may also be considered.
If the component is subsequently to be painted or coated, surface preparation should not be limited to oil removal alone. Chemical or ionic residues resulting from the cleaning process may also need to be controlled. Where appropriate, neutralization and ionic residue control can form complementary stages of the preparation process.
Where rust, old paint or physical surface defects are present, the necessary mechanical preparation methods should be carried out separately. Within this overall process, chemical degreasing specifically addresses the removal of oil and process-related contamination from the surface.
When selecting a cleaning product, the type of metal, existing surface coating, nature of the contamination and subsequent maintenance operation should be evaluated together. Component cleaning thus becomes an integral part of a controlled surface preparation process.
