Abstract
In this project, the production of ceramic foams was jointly developed by the replica method, starting from a simple triaxial ceramic suspension; a calorific system for the measurement of thermal conductivity in insulating materials; and a vacuum thermal insulation panel.
In the case of ceramic foams, the production of plates with a surface area of ≈100x150 mm, with thicknesses of 5 to 10 mm, was successfully achieved.
Taking into account that obtaining these dimensions in the laboratory is difficult to achieve, the final product is remarkable and satisfactory, which was derived from a mixture of three main elements, namely, feldspar, quartz and kaolin powders, subjected to specific temperature ramps for the pre-sintering and sintering of the ceramic; using, in addition, the replica method with polymeric foams as a matrix for the pore size and dimensions of the plate.
Regarding the heating system, using the SolidWorks program, a set of metal plates, milled inside for the optimal circulation of fluids with different temperatures, through it was designed efficiently and conveniently.
Using metallic plastic bags and a vacuum pump, a thermal insulation panel was forged, using different materials as an internal structure, including ceramic foams and mineral wool; this in order to demonstrate that the vacuum decreases the value of thermal conductivity in the materials to which it is applied, provided that this is optimal for it, that is, the cellular structure that allows the action and conservation of said vacuum.
