Industrial degreasing techniques: etching

Reducing energy costs and improving the ecological purity of the materials remain the most problematic issues of degreasing surfaces. As practice shows, the existing degreasing water compositions at low temperatures (25-30 ° C) do not not provide the high quality of the surface cleaning. Decent results are likely to be achieved only with the use of organic solvents and emulsion formulations, but it negatively affects the environment. The contradiction is removed to a certain extent in the application of thermal degreasing methods, but it is not always a panacea for certain financial reasons. Such options as the use of compositions which do not require subsequent washing (for example, BOC-5) or allow discharging wash water without pre-cleaning can be considered, but hardly possible to resort to.
