L'inchiostro Magenta di Hubergroup è caratterizzato da un pigmento instabile che, sopratutto con le alte temperature, tende a rendere il sistema difficilmente trattabile; infatti, con il clima caldo dei mesi estivi, il prodotto si scalda particolarmente durante le diverse fasi del processo produttivo, acquisendo un comportamento reologico inadeguato e problematico per i clienti a cui il composto è destinato. Sono state apportate opportune modifiche all'impianto produttivo al fine di migliorare il controllo della temperatura durante le fasi del processo, associandovi, contemporaneamente, analisi reologiche del carattere tissotropico del materiale tramite reometro rotazionale.

Abstract
Hubergroup's Magenta ink is characterized by an unstable pigment which, especially with high temperatures, tends to make the system difficult to treat; in the summer months, the product heats up during the various phases of the production process, acquiring an inadequate and problematic rheological behavior for the customers for whom the compound is intended. Appropriate modifications were made to the production plant in order to improve temperature control during the process phases; rheological analyzes of the thixotropic character of the material were made using a rotational rheometer.File | Dimensione | Formato | |
