20.500.12556/DiRROS-9279 Formaldehyde barrier efficiency of melamine impregnated paper and melamine edge-banding tape surfaced particleboard and MDF Učinkovitost papirja, impregniranega z melaminsko smolo, in melaminskega robnega traku pri oblaganju ivernih plošč in MDF-plošč z vidika zmanjšanja emisije formaldehida Particleboard and MDF are the most usable materials for furniture production, where emission of formaldehyde should be as low as possible. In order to improve aesthetic properties of particleboard and MDF they are covered with appropriate surfacing material. In most cases, melamine impregnated paper is used for face layers. But covering faces should be accompanied with covered edges, as due to low density of core layer formaldehyde much more easily emits from edges than from faces. The presented research shows differences in formaldehyde emission rate at unsurfaced and surfaced MDF and particleboard. For face layer, melamine impregnated papers with grammages of 130 g/m2 and 200 g/m2 were used, while for covering edges, melamine edge-banding tape was applied. In the research it was determined that higher barrier effect was achieved when impregnated paper with a grammage of 200 g/m2 was used. When surface was completely covered with impregnated paper and melamine edge-band tape, formaldehyde emission was lowered by between 83 % and 94 %. Iverne in MDF-plošče so najpogosteje uporabljen material za izdelavo pohištva, kjer se zahteva čim nižja emisija formaldehida. MDF- in iverne plošče se s ciljem doseganja želenih estetskih karakteristik površinsko obdelajo z ustreznimi materiali. Največkrat so to papirji, impregnirani z melaminsko smolo. Samo oblaganje ploskve pa z vidika zmanjšanja emisije formaldehida ni zadostno, saj formaldehid bistveno laže prehaja skozi rob, kar posledično pomeni, da je treba obdelati oz. zapreti tudi robove. V predstavljeni raziskavi smo iverne in MDF- plošče obložili z impregniranim papirjem gramature 130 g/m2 in 200 g/m2, robove pa zaprli z melaminskim robnim trakom. Efektivnejša zaščita proti emisiji formaldehida je bila dosežena z uporabo impregniranega papirja gramature 200 g/m2. V primeru, da so bili zaprti tako robovi plošč kakor tudi ploskve, se je emisija formaldehida zmanjšala med 83 % in 94 %. particleboard MDF surfacing melamine impregnated paper melamine edge band-tape formaldehyde emission iverna plošča MDF oblaganje papir impregniran z melaminsko smolo melaminski robni trak emisija formaldehida true false true Angleški jezik Angleški jezik Delo ni kategorizirano 2018-11-13 12:50:20 2018-11-13 12:55:40 2022-08-24 18:07:29 0000-00-00 00:00:00 2018 0 0 str. 43-50 Vol. 116 2018 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*86(045)=111 2335-3112 10.20315/ASetL.116.4 5236902 266761216 RAZ_Medved_Sergej_i0.pdf RAZ_Medved_Sergej_i0.pdf 1 C275C2BC6DCE70A5E1BA31852196B029 9e815e50afacff9e7fba02cbc8f9ad6b85c9c0e49dc047f671aabc0425ce5def 7c5d924a-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/65b7b3c5-a835-4805-9ccc-34913aa6d457 https://dirros.openscience.si/Dokument.php?lang=slv&id=11090 https://doi.org/10.20315/ASetL.116.4 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=11088 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
