The thesis was developed based on the internship activity carried out in the company. It has been divided into three parts: Introduction of the company and description of its history and what it does, description of dispersion, phenomenon of interest in production processes as printing inks are produced and a report on the work carried out with attached conclusions. This last part has been divided into three macro activities. The first concerned a collection of process variables that influence dispersion such as temperature, time taken for the process and speed of the impeller with consequent analyzes to understand their influence on the phenomenon studied. In the second part, sampling was carried out on the inks of interest for the study with consequent analysis in the laboratory through the use of a grindometer and filtration, while in the last part all the information in possession was analyzed and solutions developed to optimize the process.
L'elaborato scritto è stato sviluppato basandosi sull'attività di tirocinio svoltasi in azienda. È stato suddiviso in tre parti: Introduzione dell'azienda e descrizione della sua storia e di cosa si occupa, descrizione della dispersione, fenomeno di interesse nei processi produttivi in quanto si producono inchiostri da stampa e un resoconto sul lavoro svolto con annesse conclusioni. Quest'ultima parte è stata suddivisa in tre macro attività. La prima riguardava una raccolta delle variabili di processo che influenzano la dispersione quali temperatura, tempo impiegato per il processo e velocità della girante con conseguenti analisi per capire la loro influenza sul fenomeno studiato. Nella seconda parte sono stati fatti dei campionamenti sugli inchiostri di interesse per lo studio con conseguente analisi in laboratorio tramite l'uso di grindometro e filtrazione mentre nell'ultima parte sono state analizzate tutte le informazioni in possesso ed elaborato delle soluzioni per ottimizzare il processo.

Abstract
The thesis was developed based on the internship activity carried out in the company. It has been divided into three parts: Introduction of the company and description of its history and what it does, description of dispersion, phenomenon of interest in production processes as printing inks are produced and a report on the work carried out with attached conclusions. This last part has been divided into three macro activities. The first concerned a collection of process variables that influence dispersion such as temperature, time taken for the process and speed of the impeller with consequent analyzes to understand their influence on the phenomenon studied. In the second part, sampling was carried out on the inks of interest for the study with consequent analysis in the laboratory through the use of a grindometer and filtration, while in the last part all the information in possession was analyzed and solutions developed to optimize the process.File | Dimensione | Formato | |
