Comparative assessment of technology features impact on thermophysical characteristics of filled elastomers with a carbon component

Relevance. The need for a comprehensive study of the properties of polymer composite materials with carbon components, which are characterized by resource, energy and environmental efficiency. Their important advantages include industrial manufacturing technology, low cost, and light weight. Such features make them promising as materials for products used in the exploration and production of oil and gas resources. The materials operate under the impact of changing external environments, mechanical effects and other factors. The operation of such materials is accompanied by controlled processes of heat exchange and heat transfer, for example, to ensure the required thermal conditions during oil and gas transportation through pipelines. In this regard, experimental studies of the thermophysical characteristics of materials, from which products of various shapes for the needs of the oil and gas industry are manufactured, using industrial technology, are relevant. Aim. To study of the impact of technology features on thermophysical characteristics of filled elastomers with a carbon component. Objective. Dependencies of the thermophysical characteristics of filled elastomers with carbon components on the technological modes of manufacturing products of a wide range of shapes from them. Methods. Instrumental measurement of thermophysical characteristics, X-ray structural, statistical and correlation analysis. Results. The authors have studied the dependences of heat capacity, thermal conductivity, and thermal diffusivity on the technology features (product profiling and vulcanization method) for filled elastomers with carbon components. They revealed the patterns of change in characteristics. It was found that changing the profiling and vulcanization method has a greater effect on thermal conductivity and thermal diffusivity coefficients than on heat capacity. Their relationship with the characteristics of the material structure was analyzed. Based on the studies performed, recommendations were proposed for selecting a technology depending on the area of ​​application of the final products.
