Abstract
Tijekom prerade kompozitnog materijala sastavljenog od aluminijske folije oplemenjene laminiranim poliolefinskim troslojem nastaju defekti poliolefinskog trosloja kao posljedica stvaranja gela koji uvelike smanjuju kvalitetu dobivenog proizvoda. Samim time dovode do značajnih proizvodnih gubitaka jer su, uz vizualna, narušena i barijerna svojstva materijala. Navedeni kompozitni materijal se dobiva laminiranjem triju koekstrudiranih slojeva poliolefina na aluminijsku foliju. Uzroci nastajanja gela mogu biti različite prirode, kao što su neadekvatni ishodni materijali, nestručno rukovanje i skladištenje ili pak neprimjereni procesni uvjeti preradbe zbog čega nastaju i različite vrste gelova. U ovom radu provedena je toplinska analiza uzoraka poliolefinskih materijala, nastalih defekata te samog kompozitnog materijala termogravimetrijskom analizom i diferencijalnom pretražnom kalorimetrijom. Također, provedena je FTIR spektroskopska analiza. Temeljem dobivenih podataka određena je vrsta nastalog gela.
Abstract (english)
The emphasis of this work is investigation of defects due to the gel formation on the surface of composite material consisting of aluminium foil laminated with three layered polyolefinic film. Such defects lead to significant manufacturing losses and the visual and barrier properties of material are being disturbed as well. Mentioned composite is being manufactured by laminating of three different coextruded polyolefinic layers on aluminium foils surface. Gels forming causes are different as formed gels can vary in nature due to the usage of inadequate start materials, incompetent operation and storage or unsuitable process conditions. Thermal analysis of used polyolefinic materials as well as formed defects and composite material was performed applying thermogravimetric analysis and differential scanning calorimetry. In addition, FTIR spectroscopic analysis was performed. Concerning the obtained results, type of formed gels was determined.
