Abstract
This article reflects the results of experimental studies on determining the can surface cleaning quality. Two-stage washing of can surfaces was performed based on the results of the factor-at-a-time experiments. It furnished a number of dependences of cleaning quality on the detergent concentration at different washing solution temperatures, as well as on the washing solution temperature at various solution concentrations at fixed washing machine drive wheel rotation frequency. Based on the findings of the studies carried out, it was proved that the cleaning quality indicators increase sharply when the washing solution concentration ranges between 1 and 3 g/L. The optimum temperature providing high-quality cleaning of the can surface as per the standard ranges between 65 and 85°C, and the optimal rotation frequency of the washing machine drive wheel is 20-35 min-1.
