The influence of environment parameters on corrosion processes of livestock farms equipment

The method of definition of corrosion speed depending on the parameters and conditions of environment in cattle-breeding premises has been developed. The research objec-tive is the establishment of dependencies of speed of corro-sion of metal designs from the type of paint and varnish cov-ering and environment parameters. For the achievement of goal dependence of quantitative index of speed of corrosion on structure and condition of the environment is offered. The concentration of dioxide of sulfur, dioxide of chlorides and ammonia, and also relative humidity and air temperature in a livestock farm are chosen as the main components influenc-ing corrosion speed. The offered model allowed determining the speed of corrosion of details of the design of the product and the term of service of the object in general. The model was confirmed experimentally. The coincidence of theoretical data found by means of mathematical dependences and re-ceived by practical consideration confirmed the relevance and operability of mathematical model. The dependence of life time of protective paint and varnish covering on the intensity of vibration on different sites of protective guards was re-vealed. On the first site the depth of corrosion penetration was higher, than on the second, and on the second it was above than on the third, it occurred because of the reduction of vibration on different sites. The results of the research: 1) it was defined that the speed of corrosion of metalwork de-pended on the type of paint and varnish covering, structure and the state of environment, such as humidity, temperature, concentration of impurity of air, timely carrying out mainte-nance of a metalwork, and also the intensity of vibration; 2) the model of course of processes of corrosion taking into account parameters of environment which allows to determine the speed of corrosion of the metal protected by paint and varnish covering was formulated. On this model the exact result even without practical experiments allows to be dis-charged. The result of calculation of the depth of corrosion of model made 0.59 mm, and average at experiment - 0.60 mm; 3) the possibility of application of this model is proved in prac-tice for a choice of the acceptable composition of a paint and varnish covering.
