COMPOSITION AND PROCEDURE FOR APPLYING PHASE CHANGE MATERIALS (PCMS) TO NATURAL STONE

摘要

This Invention is a composition of phase change materials (PCM) and its application to the natural stone In order to improve its thermal properties. Several PCMs are used according to the type of stone and the way they are introduced or applied to the stone: the use of powdered PCMs, emulsions, etc. depends on the stone porosity and on the way the PCMs will be applied. The PCMs are incorporated into the natural stone as: Layer on the stone's surface. Filler applied In the back surface of the natural stone. Reinforcing Interlayer (for example, as a mortar) applied in the back surface of the natural stone. Impregnation by immersion of the stone in a solution with PCM.
