Creation of aerosolized detergent compositions for cleaning high-precision metal mirrors

Abstract

We report on a studies on the possibility of extending the service life of products of non-ferrous metals by physical and chemical treatments with specially created azeotropic compositions. These studies were carried out on high-precision copper mirrors for high-power CO2 lasers, exposed during operation to different climatic influences, worsening of their operational characteristics. The results obtained in this paper can be applicable for physical and chemical cleaning of such mirrors and other high-precision parts from non-ferrous metals. The work is devoted to the creation of aerosol detergent compositions intended for use during the operation of mirrors in the field climatic conditions. It is shown that when aluminium and tin-plate aerosol containers are used, compositions that are used to clean metal mirrors should not contain chlorine-substituted hydrocarbons or even “traces” of water and hydroxyl ions. In addition to copper mirrors, optical elements made of other materials were also studied in this work.
