[ES] Uno de los problemas que tiene la industria de pavimentos cerámicos es la rotura de piezas en la línea de producción. Una mejora en la resistencia mecánica de las piezas crudas permitiría una reducción de gastos y de materia prima, con el consiguiente aumento de producción a un menor coste, lo cual beneficiaría tanto a la industria como al consumidor final. Por tanto, la evaluación de la resistencia mecánica de piezas crudas a partir de una población estadísticamente significativa es una tarea que contribuye a predecir la posible rotura frente a tensiones. Se han analizado dos tipos de pavimentos, gres rojo y gres blanco, y un soporte de revestimiento. Se ha estudiado el efecto de la presión de conformado de la pieza en la resistencia, observándose distinto comportamiento en función del tipo de pasta empleado. Los resultados se han interpretado utilizando el análisis estadístico de Weibull, determinando los módulos de Weibull de cada material en crudo.
[EN] Ceramic tiles often experiment failure along the production line. Increasing the mechanical resistance of the green tiles would bring a reduction in raw materials waste and therefore a lowering of cost. This would be, of course, beneficial for the producer as well as the final consumer. In this sense the statistical evaluation of the strength of the green tiles can be an interesting starting point. In the present work, two types of stonewares and one wall tile have been tested. Samples were machined from green tiles, from different areas, and for different forming pressures. Possible effects between these factors and the strengths have been discussed. Estimation of the Weibull modulus for each material has been done.
