Abstract
Formulations of metal corrosion converters for modern construction based on orthophosphoric acid with the inclusion of surfactants is developed. Their feature is the use of Lewis acid solution as a functional additive, which allows you to quickly (5 minutes) treat the metal surface. The hydrogen indicators of the resulting systems have been studied. The effect of low temperatures on the pH of the studied solutions and the speed of metal surface treatment after their exposure at -18 and -2 °C were evaluated. At -29°C, crystallization of all compositions is observed. It was also found that the developed compositions of metal corrosion transducers retain their physical and mechanical properties even after long-term freezing (90 days). The proposed compositions are recommended to be used in the winter season (at temperatures below -10°C) only in the presence of greenhouses or internal heating.
