Investigation of properties of liquid ceramic thermal insulation materials.
Abstract
Today nanotechnology is widely used in the creation of building materials. In some cases, such technologies allow obtaining materials with improved characteristics. In the domestic and foreign markets the new generation of the building heat insulation materials are represented by liquid ceramic heat-insulating materials manufactured with the help of nanotechnology. Liquid ceramic thermal insulation is a composition of glass evacuated nanospheres based on aqueous solutions of acrylic polymers. It is the technical vacuum inside the nanosphere that explains the high heat-shielding properties of such materials. To determine reliable thermal conductivity coefficient for thermal insulation paint, the experiment has been planned. The designed plan corresponds to the complete factorial experiment. With 4 influencing factors 16 measurements of the density of heat flux through a flat sample of thermal paint with a thickness of 7,5 mm were made to calculate the coefficient of thermal conductivity. Microprocessor device MTF-MG4 was employed in the measurements.
