ON PROBLEMS OF PROTECTION AGAINST ATMOSPHERIC CORROSION OF MACHINERY AND EQUIPMENT IN AIC

An analysis is given of some corrosion problems in the agro-industrial complex associated with various climatic conditions, specific operating environments for machinery and equipment, and some particular solutions are shown related to the use of anti-corrosion materials available and effective in agricultural production. When tested in a 3% NaCl solution for 160 days, sunflower and rapeseed oil sludges, waste motor oil purification products are effective. Protective efficiency is 89-90%. The study of soil extracts by the method of polarization curves showed that leached chernozem is more corrosive than ordinary chernozem and dark chestnut soils. Additives to soils with mineral fertilizers increase their corrosive aggressiveness, especially in the presence of moisture. The rate of corrosion in soil extracts in the presence of ammonium nitrate is 10-15% higher than in the presence of azophoska, superphosphate, and urea. Sunflower oil sludge protects the surface of 0.8 kp steel with traces of mineral fertilizers with a protective efficiency of 97-100. It has been found that at high humidity, steel is more susceptible to general corrosion than copper or brass. This trend persists at H = 100% and the simultaneous presence of CO2, H2S, NH3 in concentrations three times higher than the maximum allowable for livestock buildings. Solving the problem of the correct choice of anti-corrosion materials will reduce the losses from corrosion destruction of agricultural machinery and equipment, while observing the principle of adequacy of the cost of protection and corrosive aggressiveness of the environment.
