Scientific and technical principles of designing equipment for molding products from polymeric compositions on account of their viscoelastic properties

Applied a comprehensive approach to modeling various stages of the process of extrusion - forming and cooling products to the changing rheology and melt viscoelastic effects in it, that affect the final product configuration. The methodological approach allows the numerical simulation of the formation of products from polymeric materials, design extrusion-forming equipment based viscoelastic deformation effects of products and make adjustments to the design and process parameters to achieve the form of products, more relevant given.

Development of conservation regulations compression carbon and graphite products

Energy-saving constructions and regulations of the Castner furnaces operation were developed for graphitization of large-sized electrode workbenches, which have no other analogue in Ukraine and reach energy expenses decrease by 20–25 %. Thermal and electrical furnace state was experimentally investigated during graphitization of electrode workbenches with different expansion blocks. It was found out that gasification process of carbon material by water vapor occurs in operation area during graphitization process in the Castner furnace.
