Lepljenje lesa z lepilom iz odpadnega polistirena : diplomsko delo = Bonding of wood with the adhesive from waste polystyrene : B. Sc. thesisKordiš, AljažRazvoj in produkcija plastičnih materialov sta od druge polovice 20. stoletja pa vse do danes močno narasla, to pa je s seboj prineslo velik ekološki problem. Iz leta v leto svet proizvede vedno več ... naravno obstojnih plastičnih odpadkov, ki se kopičijo v naravi. Ena izmed rešitev je njihova reciklaža in ponovna uporaba za izdelavo novih izdelkov ali polizdelkov. Reciklirana plastika, predvsem termoplasti, imajo potencial tudi v lesni panogi. V naši raziskavi smo iz odpadnih kavnih lončkov in žličk iz polistirena ter s topilom dimetilformamid izdelali lepilni mešanici za lepljenje lesa ter izdelali lepljence za ugotavljanje strižne trdnosti lepilnih spojev po standardu SIST EN 205:2016. Uporabili smo dve temperaturi stiskanja (150 °C in 120 °C) ter štiri načine temperiranja lepljencev pred odprtjem stiskalnice. S primerjavo različnih postopkov stiskanja smo ugotovili, da lepilo iz lončkov najvišjo trdnost doseže po ohladitvi lepljencev na 75 °C preden smo jih vzeli iz stiskalnice, medtem ko lepilo iz žličk po hlajenju lepljencev na 100 °C ali 25 °C. Ugotovili smo tudi, da se s hlajenjem lepljencev na nižjo temperaturo pred odprtjem stiskalnice bistveno zmanjša variabilnost rezultatov, kar priča o bolj zanesljivih lepilnih spojih. Zahteve standarda SIST EN 204:2016 smo uspeli doseči z lepljencem, ki je bil zlepljen z lepilom iz lončkov pri temperaturi 150 °C in ohlajen na 75 °C preden smo ga vzeli iz stiskalnice.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
