Shpyr'ko M. Heat-resistant heat-insulating materials on the basis of inorganic binders and mineral fibers

Object of researches are processes of forming of structure and properties of heat-insulation materials of combined structure on the basis of inorganic binding and mineral fibres, modified by additions. Objectives of dissertation work is a theoretical and experimental ground of receipt of heat-resistant heat-insulation materials of the optimal combined structure on the principles of inorganic binding and mineral fibres with high operating properties by establishment of conformities to law of forming of their structure by modifying additions. Theoretical researches were conducted on the basis of analysis and systematization of scientific pictures of properties of heat-insulation materials. During the experimental researches the mathematical methods of planning of experiments, and also physico-chemical methods of analysis, were used. Theoretical and practical results are brand new: at first scientific bases and found out conformities to law of forming of the optimum combined structure which is characterized by the coefficient of heat-conducting 0,058–0,22 Vt/(m•K), durability 0,6–0,95 MPa are in the interval of temperatures 298–1273 K and by a heat-resistance 95–105 of air heat changes, that is arrived at due to the regulated amount binding and mineral fibres, and also putting into the contact areas of additions, in composition of which Mn, MNO and cations of sodium, or Na2О, CaO, Al2О3, SiО2. Results of researches were realized by providing of industrial group heat-isolation materials on OOO Factory “Basalt Manufactures” and used on OOO “UDK”. Scope: construction іndustry.
