Polymer shaping on vacuum-hot forming device

U ovom završnom radu bilo je potrebno prikazati postupke tehnologije prerade polimernih materijala te dati kratak pregled polimera, njihovog dobivanja i podjelu. U sklopu završnog rada izrađen je uređaj za vakuumsko toplinsko oblikovanje plastomera te je u teorijskom dijelu rada naglasak stavljen na svojstva i vrste plastomera. U eksperimentalnom dijelu rada provedeno je ispitivanje parametara vakuumskog toplog oblikovanja na prionjivosti polipropilenske folije dvije različite debljine, na ispitni model. Rezultati su pokazali da parametri postupka vakuumskog toplinskog oblikovanja imaju velik utjecaj na prionjivost polipropilenskih folija te da je u konkretnoj industrijskoj primjeni postupka potrebno provesti optimiranje parametara postupaka u ovisnosti o debljini materijala koji se oblikuju kako bi se dobili najbolji rezultati.In this thesis paper, it was necessary to show the procedures of polymer processing technology and to give a brief overview of polymers in general, how trey are produced and their classification. As part of this thesis paper, a device for vacuum-hot forming of plastomers was developed. In the theoretical part of the paper, emphasis was put on the properties and types of polymers. In the experimental part of the paper, an examination was conducted to determine the parameters of vacuum hot forming on the adhesion of polypropylene foil of two different thicknesses to the test model. The results have shown that the parameters of the vacuum-hot forming process have a great influence on the adhesion of the polypropylene foils and that in industrial applications of the process it is necessary to optimize the parameters of the processes depending on the thickness of the materials to be formed in order to obtain the best results
