Evaluación de las condiciones del polvo atomizado empleado para la fabricación de gres rojo (monoquema-revestimiento de pisos cerámicos) en la Empresa C.A. Ecuatoriana de Cerámica.

Abstract

The drying conditions of the atomized powder used in the manufacture of Red Stoneware (Monoquema Ceramic Floor Coating) in C.A. Ecuatoriana de Cerámica. Therefore, I started by evaluating the drying conditions of the atomized powder used to manufacture the aforementioned product. This evaluation was carried out under a tri-factorial experimental design of three levels with three repetitions, which consisted in the analysis of the operational variables, transport and quality parameters (humidity, granulometry and morphology) of the atomized powder, from the production of the same in the atomizer, through its storage in the silos 5.9 and three random silos (11,12 and 4), until the discharge of the aforementioned silos the presses. All the variables involved in the experimentation were evaluated by means of the multiple linear regression method, being these related to the percentage of fissure present in the final product (Gres redMonoquema-glossy ceramic floor covering, format 43x43), which was manufactured with the atomized powder of each silo studied, with the aim of knowing the cause for the appearance of said superficial defect (fissure). It was detected that the cause for the origin of the fissure is the incorrect geomorphological of the atomized grain, for which they implemented changes in the final process. For which it is suggested to C.A. Ecuatoriana de Cerámica implement the suggested improvement plan in order to increase the export quality of the product in question and generate a high profit margin in its sale.
