Effect of ceramic dental waste in thermo-physical properties of materials composed with polyester resins
Thermophysical properties at room temperature of a composite material based on polyester resins and powders obtained from dental ceramic residues for mixtures with percentage by weight of 50-50, 60-40, 70- 30, 80-20 and 90-10 are recorded, where the minority phase are dental ceramic powders with par...

| description | Thermophysical properties at room temperature of a composite material based on polyester resins and powders obtained from dental ceramic residues for mixtures with percentage by weight of 50-50, 60-40, 70- 30, 80-20 and 90-10 are recorded, where the minority phase are dental ceramic powders with particle size through sieve No. 200 (75 um), and the majority of pre-accelerated polyester resin brand P-2000, and as catalyst (Meck-Peroxide). The manufacturing process of the specimens was by casting them into cylindrical molds of diameter 3 cm and 6 cm long. The properties of conductivity (k) and thermal diffusivity (α) and the specific heat per unit volume (ρc), were found using the KD2 Pro® system which operates on the physical principle of linear transient heat flow. Thermal effusivity (ε) was determined using data from k and α, and the expression ε = k/√ α. The results show that as the percentage of the ceramic powder is increased, the density of the samples increases, and thus the thermal conductivity (k), which is directly proportional to both heat diffusion rate (α) and the amount of heat that the material can store or release (ρc). These results suggest a new material for technological applications, as well as they help to mitigate the environmental impact due to the recycling process of dental ceramic waste. |

Se reportan las propiedades termofísicas a temperatura ambiente de un material compuesto a base de resinas de poliéster y polvos obtenidos de los residuos cerámicos odontológicos, para mezclas con porcentaje en peso de 50-50, 60-40, 70-30, 80-20 y 90-10, donde la fase minoritaria son los polvos cerámicos odontológicos con tamaño de partícula pasante tamiz No. 200 (75 µm), y la mayoritaria resina de poliéster preacelerada referencia P-2000, y como catalizador (Meck-Peróxido). El proceso de elaboración de las probetas fue por colado en moldes cilíndricos de diámetro 3 cm y altura 6 cm. Las propiedades de conductividad (k) y difusividad (α) térmica, así como el calor específico por unidad de volumen (ρc), fueron halladas usando el sistema KD2 Pro®, el cual funciona con el principio físico de flujo lineal transitorio de calor, la efusividad térmica (ε), se determinó usando los datos de k y α, y la expresión ε=k⁄√α. Los resultados muestran que a medida que se incrementan el porcentaje de los polvos cerámicos, la densidad de las muestras aumenta, y por ende la conductividad térmica (k), la cual es directamente proporcional tanto a la rapidez de difusión de calor (α) como a la cantidad de calor que puede almacenar o liberar (ρc) el material. Estos resultados proponen un nuevo material para aplicaciones tecnológicas, al igual que, permitirán contribuir a mitigar el impacto ambiental, debido al proceso de reciclaje de los residuos cerámicos odontológicos.
