Vpliv recikliranja polietilena visoke gostote na površinske mehanske lastnosti polimernega izdelka : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoGale, VeronikaPolietilen visoke gostote je eden izmed najpogosteje uporabljanih polimernih materialov. Zaradi želje po ohranitvi okolja in pomanjkanju surovin za izdelke iz polimernih mas (zlasti v bližnji ... prihodnosti) se vzpodbuja njihovo recikliranje. Vendar se po večkratni predelavi istega materiala njegove mehanske lastnosti spremenijo do te mere, da bi ga lahko obravnavali že kot drugačno snov. V okviru raziskovalne naloge smo preverili, ali lahko napovemo modul elastičnosti in trdoto mešanic nepredelanega in recikliranega HDPE po pravilu mešanja. Mehanske lastnosti smo merili pri 6 različnih deležih tako za 10- kot tudi 30-krat recikliran material. Za vsako razmerje smo izdelali vzorce in na njih izvedli meritve z nanoindentacijo po metodi CSM. Rezultati so pokazali, da niti trdote niti modula elastičnosti nobene izmed izbranih mešanic ne moremo napovedati po pravilu mešanja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [V.
