| Popis: | With the development of building technologies, there is a need for new finishing materials that must meet the requirements of modern standards. This concerns not only the pricing policy, but also the high quality of promising materials, that first of all, is manifested in strength characteristics. In order to strengthen and preserve the heat-insulating properties and corrosion resistance, it is proposed to introduce schungite of type III of various grades in the formulation of siding panels made of polyvinyl chloride (PVC). The analysis of the quality indicators of PVC panels was carried out and three main indicators were identified: melt flow rate; Charpy impact strength; bending stress. PVC siding panels with the addition of shungite were produced by injection molding. As a result of experimental studies, the dependence of the Charpy impact strength of PVC panel samples without notching and bending stress on the bulk density of schungite was revealed, and scattering diagrams of the dependence of the melt flow rate on the polymerization time and the melt flow rate on the PVC concentration were constructed. The effect of schungite concentration of various grades on the melt flow rate was revealed. The dependence of shungite application as a reinforcing filler on the decrease in the melt flow rate in comparison with the traditional filler is determined. |
