摘要:The cleaning technology plays an important role in product quality during the remanufacturing processing. Remanufacturing cleaning is among the most demanding steps and is a particularly essential process in remanufacturing. In the meantime, remanufacturing cleaning is often the main source of pollution in the remanufacturing process. During the past decades, supercritical fluids due to their unique properties gained an increasingly attention in many cleaning industries. The supercritical carbon dioxide as a novel cleaning technology for remanufacturing cleaning process is discussed, which can realize cleaning and drying at the same time, promoting a greener solution for remanufacturing industry. In this paper, we reported the experimental results of the effect of some operating parameters. The CO2 at different operating pressures, temperatures and residence time was made to continuously flowing over this. The decontamination rate and amount were monitored and compared. The obtained results show that the optimum parameters were operating temperature and pressure of 60 degrees C and 20 MPa respectively, to have the highest decontamination rate value at the investigated experimental conditions. In additon, the success of supercritical CO2 cleaning effectively promotes the research for next-generation cleaning methods for remanufacturing industry. (C) 2013 Elsevier B.V. All rights reserved.
