Mikokompozīti kā alternatīva tradicionāli izmantotajiem iepakojuma materiāliem

2021

Nemainīga globāla problēma ir plastmasas piesārņojums, tādēļ pēdējā laikā aktualizējušies ekoloģiski iepakojuma materiāli no micēlija un augu biomasas. Pētījumā tika izveidoti sējas kaņepju spaļu, āra bērza ēveļskaidu un zāģskaidu un Trametes versicolor micēlija mikokompozīti ar pievienotām kviešu klijām un bērza mizu. Tika izvērtēta substrāta granulometrijas un sastāva ietekme uz mikokompozīta spiedes stiprību, ūdens uzsūcamību un noturību pret pelējumu. Labāko micēlija augšanu un mehāniskās uzrādīja paraugi ar pievienotām klijām, pazeminātu ūdens absorbciju – bērza mizu saturošie paraugi, pret pelējumu visiem paraugiem bija ļoti zema noturība. Būtiskāk par granulometriju bija micēlija dau…
