Abstract
Z vstopom Slovenije v Evropsko zvezo smo tudi pri nas uveljavili strogo okoljsko zakonodajo. Za lesnoindustrijska podjetja je še posebej pomembna direktiva VOC o omejevanju emisij hlapnih organskih spojin (HOS). Uredba o emisiji HOS iz naprav, ki uporabljajo organska topila, zahteva drastično zmanjšanje emisij HOS tudi iz lakirniških obratov v lesnopredelovalni industriji. Izkazalo se je, da je v večini primerov edina realna možnost za implementacijo uredbe prehod na vodne premazne sisteme. V lesnopredelovalnem podjetju smo z vodnimi premaznimi sredstvi obdelali elemente 3 najbolj pogostih proizvodnih programov in njihove lastnosti primerjali z lastnostmi premazov na osnovi organskih topil. Rezultati so obetavni, vendar pa so vodni površinski sistemi še vedno v fazi razvoja in večinoma ne omogočajo doseganja najvišje kakovosti površinske obdelave, kot to velja za premaze na osnovi organskih topil.

Title:Introduction of water-borne surface coatings into production of kitchen elements made of massive wood : visokošolski strokovni študij
Abstract:
Strict environment legislation was introduced in Slovenia due to joining the European Union (EU). For wood industry the VOC directive on restriction of volatile organic compounds emissions are especially important. The decree on emissions of volatile organic compounds (VOC) from installations using organic solvents requires a drastic reduction of VOC emissions also from lacquer plants in the timber-reworking industry. In most cases the only realistic possibility for implementation of the decree is a transition to water-borne coating systems. In the Slovenian producer of furniture, we treated elements of 3 most important production programmes with water-borne coating systems, and compared their characteristics with the characteristics of solvent-borne finishes. The results are promising. But the water-borne surface systems are still in the stage of development, and therefore, they do not enable reaching the top-quality surface treatment as the coatings on the basis of organic solvents do.

Keywords:wood, surface finishing, VOC emissions, directive, polyurethane coating, water-borne coating, adhesion, gloss, hardness
