Abstract

U ovome radu provedena je analiza očvršćivanja i prijenosa topline nezasićenih poliesterskih smola u valjkastom kalupu grijanim uljem i vrućim zrakom. Vođenje topline kroz kalup ispitivano je mjerenjem temperature u središtu uzorka tijekom reakcije očvršćivanja. Na osnovi provedenih eksperimenata u kalupima i nezavisnih kinetičkih ispitivanja, te provedene numeričke analize može se dobiti potpunija slika procesa očvršćivanja u valjkastom kalupu s time da se stečene spoznaje mogu primijeniti i pri modeliranju proizvodnih kalupa u industriji. Simulacijom procesa se pokazalo dobro slaganje predloženog matematičkog modela sa eksperimentalno mjerenim temperaturama tijekom reakcije u središtu valjkastog kalupa.

Abstract (english)

In this paper, an analysis of solidification and heat transfer of unsaturated polyester in a cylindrical mold heated with oil and hot air was carried out. Heat conduction through the mold was investigated by measuring the temperature at the center of the sample during the curing reaction. On the basis of experiments in molds, independent kinetic studies and conducted numerical analysis we can get a more complete picture of hardening process in a cylindrical mold with the proviso that the acquired knowledge can be applied in the modeling of manufacturing molds in the industry. Using process simulation has shown good agreement with proposed mathematical model and the experimentally measured temperatures during the reaction in the middle of the cylindrical mold.
