20.500.12556/DKUM-86994 Analiza mehanske in kemijske obstojnosti različnih recikliranih in bio-osnovanih termoplastov kot osnova za izbiro materiala izdelka BO Daily diplomsko delo visokošolskega strokovnega študijskega programa I. stopnje Analysis of mechanical and chemical resistance of various recycled and bio-based thermoplastics as a basis for the selection of BO Daily product material V okviru diplomske naloge smo se ukvarjali z izbiranjem primernega polimernega materiala za izdelavo posode za dnevno zbiranje organskih odpadkov - BO Daily. Preučevali smo vplive različnih mehanskih in kemijskih lastnosti teh materialov na funkcionalnost in izgled končnega izdelka. Izbirali smo med štirimi različnimi termoplasti, ki so bio-osnovani ali reciklirani oz. vsebujejo del recikliranega materiala. Izbrani materiali so se med seboj razlikovali po deležu reciklata in načinu pridobivanja recikliranega materiala. En material je bil bio-osnovan. Na podlagi vseh izvedenih testiranj smo prišli do zaključka, da so se mehanske lastnosti najbolj spreminjale materialu poliamidu (PA). Na osnovi testiranj se je izkazal za najbolj krhkega – končni izdelek iz PA je ob spustu z višine počil, kar bi lahko predstavljalo nevarnost za uporabnika. Material je tudi higroskopičen, nase veže vlago in spreminja dimenzije. Zato smo ga izključili iz nabora potencialnih materialov za izdelavo končnega izdelka. Kot najustrezejši se je po izvedbi vseh testiranj izkazal polipropilen (PP) ECO Meplen, ki smo ga dokončno izbrali kot material za izdelavo posode za zbiranje organskih odpadkov, Bokashi Organko Daily. Within the scope of the thesis, we focused on selecting an appropriate polymeric material for the manufacture of a container for daily collection of organic waste - Bokashi Organko Daily. We studied the impacts of various mechanical and chemical properties of these materials on the functionality and appearance of the final product. We chose from four different thermoplastics, which were either bio-based or recycled, or contained a different amount of recycled material. The selected materials differed in the percentage of recycled content and the method of obtaining the recycled material. One material was bio-based. Based on all the tests conducted, we concluded that the mechanical properties varied most significantly in the case of polyamide (PA) material. From the tests, it proved to be the most brittle – the final product made of PA cracked when it was dropped from a height, which could pose a danger to the user. The material is also hygroscopic, absorbing moisture and changing dimensions. Therefore, we excluded it from the list of potential materials. The most suitable material, after conducting all tests, was found to be polypropylene (PP) ECO Meplen, which we selected as the material for manufacturing the container for collecting organic waste, Bokashi Organko Daily. industrijski reciklat popotrošniški reciklat bio-osnovan material mehanske lastnosti kemijska obstojnost industrial recycle post-consumer recycle bio-based material mechanical properties chemical durability true true false [N.
