20.500.12556/DiRROS-6409 Vpliv zrnatosti brusnega papirja na emisijo formaldehida iz ivernih plošč The impact of sandpaper grit size on formaldehyde emission from particleboards Brušenje je pomembna stopnja proizvodnje različnih lesnih ploščnih kompozitov. Njegov primarni namen je doseganje želene debeline in primerne gladkosti površine. Z brušenjem oz. izbiro zrnatosti brusnega papirja pa lahko vplivamo tudi na emisijo formaldehida. Da bi ugotovili vpliv zrnatosti uporabljenega brusnega papirja na emisijo formaldehida, smo iverne plošče brusili s papirji različne zrnatosti. Uporabili smo iverno ploščo debeline 16 mm, ki je namenjena za pohištveno rabo. Za brušenje smo uporabili brusni papir zrnatosti 40, 80 in 120. Emisijo formaldehida smo določili po plinski metod Sanding is an important stage of wood-based panel production, where the primary goal is to achieve a desired thickness as well as appropriate smoothness of the surface. With sanding, the emission of formaldehyde can be influenced especially by the selection of sanding paper grit size. The aim of this paper is to present how the grit size of selected sanding paper affects formaldehyde emission of three-layer particleboard. For this purpose we selected 16 mm thick particleboard for furniture use. Sanding paper with grit sizes of 40, 80 and 120 was used for particleboard sanding. Formaldehyde emission was determined by the gas analysis method (SIST EN 717-2). The findings indicate that formaldehyde emission decreases with increasing grit size of sandpaper used in the process. iverna plošča emisija formaldehida brušenje zrnatost particleboard formaldehyde emission sanding grit size true false true Slovenski jezik Angleški jezik Delo ni kategorizirano 2017-07-03 08:26:22 2017-07-03 09:29:14 2022-08-12 10:20:57 0000-00-00 00:00:00 2017 0 0 str. 1-6 Vol. 112 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8(045)=163.6 2335-3112 10.20315/ASetL.112.1 4828838 266761216 01Medved.pdf 01Medved.pdf 1 25F58EEE0D9AC8E0306EB01D866F418C b24f3d21676e4acbdf85a25fdfe69585555ab776816a7252d0b6b277bc793946 b6a0977c-17b4-11ed-b6b8-001a4af901a5 20.500.12556/dirros/60128bae-8489-4505-9f48-0f0d4f6b9596 https://dirros.openscience.si/Dokument.php?lang=slv&id=6579 https://doi.org/10.20315/ASetL.112.1 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=6578 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
