Abstract
The development of modern agro-industrial complex (AIC) directly depends on the efficiency of technical solutions, especially in agricultural engineering. In the course of seasonal field work, agricultural machinery and equipment are subjected to a significant impact of various climatic factors, including solar radiation. The intensity of this impact affects the rate of wear of materials used in machinery and equipment. Especially sensitive to this impact are flexible units, which must elastically deform under compression and tension, such units become brittle and brittle. In this regard, the purpose of this work is to study and determine the effects of solar radiation on rubber seals. Object. The object of research is samples of rubber products used in agrarian engineering as a door sealant. Materials and Methods. Within the framework of this study the materials were tested on the accelerated aging unit with ultraviolet (hereinafter referred to as UV) radiation sources. Using the testing universal electromechanical machine REM5.101.0.PS the mechanical properties of the samples were analyzed. Results and conclusions. After irradiation of the sealing rubber sample for 200 hours and radiation intensity of 25 W/m² (which is ~100 times higher than the average daily power of spectra A and B of ultraviolet radiation), the reduction of tensile strength of the objects of the study amounted to 11.5 %. Local spots of different color appeared on the samples, and also based on the presented data, due to the destruction of bonds between polymer chains and the formation of cracks and microcracks in the structure of the rubber, it led to a decrease in its strength.
