Razvoj kuhinjske deske iz termično modificiranega lesa

Hrovat, Daniel (author), Kitek Kuzman, Manja (mentor)

Les se že dolgo uporablja kot material za kuhinjske pripomočke – za izdelavo kuhinjskih rezalnih desk, ki so eden od osnovnih pripomočkov v kuhinji. Danes se pogosto uporabljajo plastične deske, ker je njihova uporaba enostavnejša. Cilj diplomske naloge je bilo izdelati rezalno desko – ploščo, ki bi bila najprimernejša za uporabo v pomivalnem stroju. Za poizkus smo izdelali 6 različnih tipov sestave plošč tako iz termično modificiranega kot iz nemodificiranega lesa. Uporabljali smo jedrovino in beljavo rdečega bora (Pinus sylvestris). Določene tipe sestave smo lepili s poliuretanskim lepilom, varili z nihajnim varjenjem in žebljali z lesenimi žeblji. Plošče smo nato testirali tako, da smo jih s komercialnim pralnim detergentom prali v pomivalnem stroju. Testirali smo tudi zmanjševanje intenzivnosti vonja skozi pranja in zmanjševanje topnih emisij v lesu s številom pranj. Ugotovili smo, da je najbolj primerna termično modificirana plošča izdelana iz križno lepljenih lamel s poliuretanskim lepilom. Intenzivnost vonja se je zmanjšala s pranji, nismo pa dokazali povezave med številom pranj in vsebnostjo emisij. Pri preizkusu o vsebnosti pralnega praška nismo našli sledi le-tega.

• Title: Development of a cutting board made of the thermally modified wood

Abstract

Wood has long been used as a material for kitchen utensils, and especially for kitchen cutting boards, one of the basic kitchen utensils. Nowadays, plastic boards are often used because they are simpler. The aim of the diploma thesis was to produce a wooden cutting board that is also suitable for use in a dishwasher. We tested boards with six different types of composition, using both thermally modified wood and unmodified wood. We used red pine (Pinus sylvestris). Certain types of composition were glued with polyurethane adhesive, welded with swing welding and nailed with wooden nails. These plates were then tested by washing them using a commercial detergent in a dishwasher. We also tested the reductions in odour intensity and emissions from the wood based on the number of washes. We found that the most suitable thermally modified cutting board is made of cross-laminated lamellae with polyurethane adhesive. The intensity of the odour decreased with washing, but we did not prove a relationship between the number of washes and the emissions. We did not find any trace of detergent in the content test.
