Namen diplomskega dela je bil oceniti možnost izdelave lesenega pohištva, namenjenega uporabi v regijah s toplim in vlažnim podnebjem. Obravnavali smo pohištvo iz redne proizvodnje, namenjeno uporabi v zmernem podnebju. V raziskavi smo največje vplive izpostavitve toplemu in vlažnemu podnebju ugotovili pri preizkušancu A, ki je bil izdelan iz iverala P2. Nabrek na korpusu in vratih je v povprečju znašal 0,70 mm. Do vidnih sprememb je prišlo pri foliji ABS, ki je ponekod odstopila od iverala. Na vzorcu B, ki je bil izdelan iz iverala P2 in javorjevega masivnega lesa, je nabrek na korpusu v opazovanem obdobju povprečno znašal 0,60 mm, na vratih 0,30 mm. Na vratih smo zabeležili 2,50 mm nabrek po širini okvirja, pokanje površinskega premaza na spojih okvirja in ugotovili ukrivljenost vrat. Vzorec C je bil izdelan iz iverala P5. Nabrek na korpusu in vratih je v povprečju znašal 0,60 mm. Na vratih smo ugotovili odstopanje pokrivne folije na robovih. Pri vzorcih B in C smo opazili vidne spremembe na korpusu, ki so bile podobne kot pri vzorcu A. Zaključimo lahko, da uporabljeni materiali (iveral P2, iveral P5 in javorjev masivni les) niso primerni za izdelavo pohištva za uporabo v tropskem podnebju, in sicer zaradi nabrekanja in drugih deformacij. Iveral P5 niso zagotavljale signifikantno boljše odpornosti proti visoki vlažnosti in temperaturi kakor iveral P2.

Abstract

This thesis assesses the possibility to produce wooden furniture for warm and humid climates. Such climate conditions had the strongest impact on test piece A made of refined chipboard P2. Average swelling on the corpus and the door was 0.70 mm. ABS foil also changed visually, partly detaching from the chipboard. Test piece B made of refined chipboard P2 and solid maple wood suffered a swelling of 0.60 mm on the corpus and of 0.30 mm on the door. A 2.50 mm swelling along the door frame and cracks appeared on the surface coating above frame joints. A bend was also observed. Test piece C was made of refined chipboard P5. Average swelling on the corpus and the door was 0.60 mm. The foil on the edges became detached. Test pieces B and C showed visible changes on the corpus similar to those of test piece A. The materials (refined chipboard P2 and P5, solid maple wood) are not appropriate for furniture to be used in a tropical climate because of swelling and other deformations. Neither type of refined chipboard (P2 and P5) was sufficiently resistant to high humidity and temperature.
