Abstract
Способ определения коэффициента эффективности сверхтонких жидких теплоизоляционных покрытий, заключающийся в том, что два слоя материала одинаковой толщины и теплопроводности закрепляют на источнике тепла, измеряют температуру источника тепла t, температуру между двумя слоями материала t, затем закрепляют на наружной поверхности верхнего слоя материала тонкую металлическую пластину, с нанесенным на нее сверхтонким жидким теплоизоляционным покрытием, измеряют температуру в контактной поверхности верхнего слоя материала и металлической пластины с теплоизоляцией t, температуру между двумя слоями материала при использовании теплоизоляции tи определяют коэффициент эффективности сверхтонкого жидкого теплоизоляционного покрытия - ηпо формуле:где η- коэффициент эффективности сверхтонкого теплоизоляционного покрытия,t- температура источника тепла без теплоизоляции,t - температуру между двумя слоями материала без теплоизоляции,t- температуру между двумя слоями материала при использовании теплоизоляции,t- температура в контактной поверхности верхнего слоя материала и металлической пластины с теплоизоляцией.The method for determining the efficiency coefficient of ultrathin liquid heat-insulating coatings, namely, that two layers of material of the same thickness and thermal conductivity are fixed to a heat source, the temperature of the heat source is measured t, the temperature between two layers of material t, then a thin metal plate is fixed on the outer surface of the upper layer of the material , coated with an ultra-thin liquid heat-insulating coating, measure the temperature in the contact surface of the upper layer of material and metal of a plate with thermal insulation t, the temperature between two layers of material when using thermal insulation t, and determine the efficiency coefficient of an ultrathin liquid thermal insulation coating - η according to the formula: where η is the efficiency coefficient of an ultrathin thermal insulation coating, t is the temperature of a heat source without thermal insulation, t is the temperature between two layers of material without thermal insulation, t- temperature between two layers of material when using thermal insulation, t- temperature in the contact surface of the upper layer of material and m metal plate with thermal insulation.
