dc.description.abstract | V práci byly testovány možnosti optimálního přepracování PVB. Cílem práce bylo sledovat degradaci PVB folií za různých podmínek hnětení a odhadnout vliv teploty, vzdušného kyslíku a mechanického namáhání na vývoj degradace materiálu. Pro potvrzení vlivu vlhkosti na vlastnosti PVB během přepracování byly folie nasyceny vodou v 0,5 a 8%ní koncentraci. Degradační změny PVB byly hodnoceny ze změn ITT, mechanických vlastností, žlutosti a molekulové hmotnosti. Ze získaných výsledků byly navrženy optimální podmínky pro přepracování. | cs |
dc.description.abstract | Possibility and conditions for optimal re-processing of plasticized polyvinylbutyral (PVB) were tested. The aim of this work was to investigate degradation of PVB sheet at various kneading conditions and to estimate the influence of temperature, air oxygen and mechanical stress on the progress of degradation process. In order to confirm the influence of humidity on the PVB properties during reprocessing, the sheets with the humidity content Of 0.5 and 8.0% were tested. The PVB degradation was determined from the changes of melt flow index, mechanical properties in terms of stress and elongation at break, yellowness and molecular weight distribution. The optimal recycling conditions for PVB were estimated from the evaluation of all measured properties and their changes. | en |
