Development and research of the dampening solutions with anti-bacterial effects to use in packaging and other offset printing production

For the first time there were developed and researched dampening solutions having anti-bacterial effects, that provide normal quality indicators such as optical density on the imprint in range of 0,9-1,5±0,05-0,10, color deviations in range of 4-5, dot gain in range of 18-25 % of raster element on the imprint; and that provide lowering isopropanol alcohol contain down to 9-10 %.

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.

Деталі, які отримані обтиском

Developed new technological foundations of obtaining the hollow articles by forming cold sheet stamping processes, including drawing, reducing and bulging. The novelty lies in the development of new methods of drawing, reducing and bulging, to create and use a special profiles deforming tool. Using this deforming tool provides a significant reduction of friction influence in the forming of articles, reduce deformation force and increase the degree of deformation in one stage.

Research and development of frequency selective structures millimeter wave based on thin multimode dielectric resonators

Equations for the of the resonant frequency and Q-factor calculation for frequency-selective devices based on thin dielectric resonators are found. Calculation error is less than 1 ... 2% for frequency and 5 ... 7% for Q-factor These equations can be the base for automatisation of calculations during the design of the devices on the base of thin dielectric resonators.
