Abstract
One of the most important problems of the national economy is the protection of metal from corrosion, causing great damage to products and structures, shortening their useful life. Taking into account the importance of protecting metal structures of livestock objects from corrosion during disinfection work, the corrosion properties of the new Penox-1 disinfectant have been studied. Studies have shown that the tested drug «Penox-1» has a low corrosion activity in relation to metal products made of aluminum, galvanized iron and stainless steel, compared with the reference drug. Thus, the solution of the Penox-1 preparation reduced the initial weight of metal plates during 24 hours of exposure from aluminum by 0,196 g, which is 7,4%, and the standard preparation by 0,836 g or 32,1%, which is 4,3 times more . Similar data were obtained in a comparative aspect with galvanized iron and stainless steel plates. When examining metal plates after testing in a Penox-1 solution, the color and structure did not change visually and under a microscope. At that time, the plates immersed in a 2% sodium hydroxide solution changed strongly in color and structure, and a yellow-gray corrosive coating appeared.
