Abstract
Uredba o mejnih vrednostih emisije hlapnih organskih spojin v zrak iz naprav, v katerih se uporabljajo organska topila, je v lesnopredelovalni in pohištveni industriji povzročila veliko težav. Podjetja bodo v prihodnosti prisiljena uskladiti emisije hlapnih organskih spojin z vrednostmi, določenimi v Uredbi. V podjetju Stilles, kjer izdelujejo stilno pohištvo in opremljajo objekte po naročilu, se je pri uvajanju vodnih premaznih sredstev pojavil problem neenakomernega obarvanja površine češnjevega lesa z vodnimi lužili. Da bi poiskali vodno lužilo, ki bo enakomerno obarvalo površino, smo preizkušali lužila različnih proizvajalcev. Merili smo površinsko napetost lužil, gostoto, delež suhe snovi, navzem pripravkov ter vizualno ocenili vzorce iz češnjevega lesa, ki smo jih lužili z novimi lužili. Vzorec, lužen z lužilom proizvajalca Helios, z oznako št. 5, je dosegel najbolj enakomerno obarvanje teksture.

Abstract:
Decree on emissions of volatile organic compounds from installations that use organic solvents has caused a lot of problems to wood processing and furniture industry. In the future, companies will be forced to comply emissions of volatile organic compounds with the values determined in the Decree. The Stilles Company, which manufactures style furniture and furnish objects by orders, faces the problem of unevenly coloured stained surfaces of cherry wood elements, stained with waterborne stains. In order to find a waterborne stain, which can provide even staining of surfaces, we tested different waterborne stains of various producers. We measured the surface tension of the stains, their density, the dry matter content, absorbtion of the preparations, and visually evaluated the samples of cherry wood stained with the new stains. The sample stained by the Helios formulation No. 5 exhibited the most even colouring of the texture.

Keywords:wood, cherry, staining, waterborne stains, absorption, stained wood
