The use of various active substances in the composition of biocides can affect specific chemical properties. Their compatibility, solubility, stability, and corrosion activity are investigated against the background of their ability to affect pathogenic microorganisms. Due to the obtained results, the manufacturer can offer their use in specific conditions (aerosol or wet use, the possibility of use on metal structures, etc.). This publication presents the results of the study of the physicochemical properties of the biocidal agent “Iodosan”, developed by the employees of State Scientific and Research Institute of Laboratory Diagnostics and Veterinary and Sanitary Expertise, based on iodine and lactic acid, dark yellow, with a moderate specific smell of iodine. The starting solution of the product is straightforward to slightly yellowish liquid with a mild iodine smell; after diluting it in tap water, the color of the water remains transparent. The agent is mixed with water to prepare a working solution, “Iodosan”, for wet and aerosol disinfection of objects. The biocidal agent “Iodosan” solution in concentrations of 0.2‒0.5 % has low corrosion activity against the treated test objects. According to research results, the most insufficient corrosion activity of the drug “Iodosan” for aluminum is observed at its concentration of 0.1‒0.5 %, steel, and galvanized steel ‒ 0.1‒0.2 %. Studies have shown that the disinfectant “Iodosan”has a surface tension of 62.03 mN/m at 20 °C. This proved that the drug has a good wetting ability, which affects the disinfecting properties. In working concentrations, the drug has a pH of 5.8. The research results confirmed the effectiveness of the biocidal preparation “Iodosan” for treating premises and equipment surfaces in optimal bactericidal concentrations, and it is recommended for use in production.

The relevance of using slag crust separation methods, which are characterized by easy separation and are based on thermodeformation processes in the sample, is shown in the development of new welding materials. The developed method of assessing slag separation based on the theoretical calculation of thermo-deformation processes in the base metal has passed the stages of experimental research The experimental approbation of the proposed methodology for assessing the separation of the slag coating from the surface of welded joints under experimental fluxes based on the TiO2-MnO-SiO2–MgO–CaO-FeO-Al2O3 slag system was carried out for different welding regimes. The evaluation criterion for the high-temperature separation of the slag coating takes into account: the ratio of the geometric parameters of the test sample, the amount of heat input during the surfacing process, and the factor of the presence of spinelforming components at the slag-metal interface. The selected parameters for evaluating the separation of the slag crust in points, where the guaranteed separation of the slag coating is counted for the arbitrary separation of the slag during its destruction or the arbitrary separation of the slag by a monolithic layer. The practical value of the proposed method lies in the possibility of quantitative assessment of the probability of high-temperature separation of the slag coating for a wide range of fluxes for surfacing. The results of the conducted experiments show the efficiency of the developed methodology for evaluating the high-temperature separation of the slag coating from the surface of the weld metal.

The production of ecologically clean poultry meat with high biological value to meet the needs of public demand is the primary goal of the poultry industry. Poultry meat is a good product for a healthy human diet due to its nutritional, dietary, and sensory properties, economic availability, and quick cooking. At the same time, using the latest, effective symbiotic and biocidal drugs to increase the productivity of poultry requires more in-depth research and evaluation of their impact on the final product. Based on the analysis of the results obtained by us, it has been proven that the use of the complex of symbiotic drugs “Biomagn” and “Biozapin” and in combination with the biocidal agents “Diolaid” and “Biolaid” to broiler chickens of the Cobb 500 cross throughout the entire breeding cycle allows obtaining high-quality and safe poultry products (chicken meat), with improved quality indicators and higher biological value. An increase in the protein content in the muscles of experimental groups of birds and a decrease in moisture in them was established, which is a consequence of an increase in dry matter content in this tissue. As a result, in the muscles of broiler chickens of the II research group, an increase in energy value was recorded to a greater extent and markedly, along with an increase in the content of essential bioelements (Calcium, Ferrum, Copper, Cobalt, and Selenium (Р ≤ 0.05)) and the content of vitamins A and B1, which indicates a higher biological (nutritional) value of poultry meat compared to such indicators in poultry I of the experimental and control groups. When determining the safety indicators of the chicken meat of the research groups, it was established that there were no residual amounts of veterinary drugs, pesticides, and aflatoxin B1, and the regulated indicators of toxic elements did not exceed the PAI specified in the regulatory documents. Therefore, the proposed complex of drugs in the scheme of the growing cycle of broiler chickens does not hurt the quality and safety of the obtained products (chicken meat). On the contrary, according to sensory and organoleptic studies, higher organoleptic qualities of the muscle samples of chickens of the I and II experimental groups were proven under the conditions of the use of a complex of symbiotic and biocidal drugs: the values of the highest overall score for tasting the meat broth are higher (Р ≤ 0.05) compared with the indicator in the control group.
