Abstract:V prispevku smo s pomočjo sistema za avtomatizirano vrednotenje zlepljenosti (ABES) ugotavljali razvoj strižne trdnosti ribjega kleja pri lepljenju lesa. Uporabili smo bukov (Fagus sylvatica L.) furnir, ki smo ga lepili pri konstantnem tlaku 12 barov, medtem ko smo spreminjali temperaturo in čas stiskanja. Temperatura je znašala med25 °C in 100 °C, z intervalom 25 °C, čas stiskanja pa od 1 minute do 60 minut. Dosežena maksimalna strižna trdnost je znašala okoli 10 N/mm², dosegli smo jo pri vseh štirih proučevanih temperaturah stiskanja. Na podlagi rezultatov študije smo ugotovili, da strižna trdnost ribjega kleja pri različnih temperaturah segrevanja neenakomerno narašča. Pri višjih temperaturah segrevanja hitreje dosežemo maksimalne strižne trdnosti. Strižne trdnosti spoja lepila iz ribjega kleja smo ugotavljali tudi po standardih EN 204 in EN 205.

Title:Shear strength of fish glue bonds of glued wood evaluated by the ABES method
Abstract:Detail of the development of the shear strength of fish glue in wood bonding using an automated bonding evaluation system (ABES) are presented. Beech (Fagus sylvatica L.) veneer was used, which was compressed at constant pressure of 12 bars while the temperature and pressing time were varied. The temperature ranged between25°C and 100°C with an interval of 25°C, while the time period was between 1 minute and 60 minutes. The achieved maximum shear strength was approximately 10 N/mm², which was reached at all four studied pressing temperature intervals. Based on the study results, we found that the shear strength of fish glue increases unevenly at different heating temperatures. Maximum shear strength values are reached faster at higher heating temperatures. The shear strength of the fish glue bonds was also determined according to the EN 204 and EN 205 standards.
