Investigation of corrosion activity and foaming properties of biocide “DezSan”
The article presents data on the study of corrosion activity and foaming properties of biocide “DezSan”. One of the main characteristics of a biocide is its corrosive activity. The use of a biocide in a poultry house involves getting it on metal, rubber, plastic surfaces, and the like. The biocide should provide minimal aggressive effect on the surface data. In the industrial poultry industry, the most frequently used equipment with surfaces made of stainless steel, aluminum and galvanized iron. Also, when choosing a biocide, pay attention to its foaming properties. They should not exceed 40%, as this ensures a quality disinfection. One of the key points is the index of foam stability, which significantly affects the time of contact with the biocide and provides effective decontamination of the surfaces. The goal of the work. To determine the corrosion activity and foaming properties of the new domestic biocide “DezSan”. Materials and methods of research. In their experiments, a disinfection tool for the production of the scientific and production company “Brovаfarma” (Ukraine) “DesSan” was used. Relative corrosion activity of various concentrations of biocide “DezSan” was determined in comparison with the standard – 1.5% solution of sodium hydroxide. To determine the foaming properties of biocide “DezSan” used the method of Ross-Miles (1983). Results of research and discussion. The biocide “DezSan” in all experimented concentrations (0.25–1.5%) has a minor corrosion effect on aluminum, stainless and galvanized steel, compared with the standard (1.5% NaOH solution). The biocide “DezSan” does not cause deformation when exposed to metal samples. “DezSan” in various concentrations has a foaming property of 13.1 to 37.3%, which increased directly in proportion to increasing the concentration of biocides. The foaming capacity of “DezSan” did not exceed 40%, and the foam stability at these concentrations varied within 0,08–0,19. Conclusions and prospects for further research. Thus, the biocide “DezSan” has low corrosion properties in relation to aluminum, stainless steel and galvanized steel in comparison with the standard (1.5% solution of NaOH). The biocide “DezSan” does not cause deformation when exposed to metal samples. The foaming capacity was not more than 40%, and the foam resistance was up to 0.19. These indicators allow the wide use of biocide “DezSan” in the poultry industry. In the future, it is planned to conduct a study of the biocid “DezSan”, identified it irritating, skin-resorptive, cumulative and other properties.
