Na kakovost lepilnega spoja furnirane iverne plošče vpliva več dejavnikov. Med njimi so tudi temperatura stiskanja, vlažnost nosilnih plošč in vlažnost furnirja. Pri poizkusu smo uporabljali furnirje, ki so bili izpostavljeni relativni zračni vlažnosti 0 %, 35 %, 65 %, 85 % in 95 % ter temperaturi stiskanja 90 °C in 110 °C. Čas stiskanja je bil pri obeh temperaturah 5 minut. Na vzorcih smo nato izvedli poizkus za trdnost spoja. Ugotavljali smo tudi vlažnost in prostorninsko maso vzorcev. Najboljše lastnosti smo dosegli pri vlažnosti furnirja 1 % in temperaturi stiskanja 90 °C. Najslabše lastnosti je dosegel furnir z 38 % vlažnostjo in temperaturo stiskanja 110 °C.

Abstract

The quality of adhesive bonding of veneered particleboards depends on several factors, including pressing temperature, carrier panels` humidity and moisture content of veneer. In the experiment exposed to relative air humidity of 0 %, 35 %, 65 %, 85 %, 95 %, and pressing temperatures of 110 °C and 90 °C were used. Pressing time for each temperature value was 5 minutes. On samples provided a bonding strength test was performed, and the moisture content values so as their volume mass recorded. The best characteristics were achieved using a veneer having moisture content of 1 % and pressing temperature of 90 °C. The worst characteristics were achieved using veneer having moisture content of 38 % and pressing temperature of 110 °C.
