Abstract
Na primeru smrekovine (Picea abies Karst.), bukovine (Fagus silvatica L.), hrastovine (Quercus robur L.) in topolovine (Populus nigra L.) je bil obravnavan vpliv lesne vrste na hrapavost zunanjega sloja brušenih ivernih plošč. Brušenje s papirjem zrnatosti 100 je potekalo do točke maksimalne prostorninske mase. Za prikaz vpliva hrapavosti so bili uporabljeni parametri Ra, Rz in Rmaks. Hrapavost je bila najmanjša pri ploščah z zunanjim slojem iz iverja iz hrastovine in iz topolovine in največja pri uporabi iverja iz bukovine. Hrapavost površine po brušenju se je najbolj spremenila pri uporabi iverja iz hrastovine, najmanj pa pri uporabi iverja iz smreke. po brušenju hrapavost površine pada z naraščajoč prostorninsko maso

Title:Influence of wood species on surface roughness and density of sanded particleboards
Abstract:
On the example of spruce (Picea abies Karst.), beech (Fagus silvatica L.), oak(Quercus robur L.) and poplar (Populus nigra L.) influence of wood species on surface roughness of sanded particleboards had been discoussed. Samples were sanded with sanding belt grid size 100 until reached the point of maximumdensity. For describing the influence of surface roughness, parameters Ra, Rz and Rmax were used. The lowest surface roughness was found in the boards whose surface was consisted of oak and poplar particles, the maximum surface roughness was found in the board whose surface layer was consisted of beech particles. Surface roughness was changed the most when we used particlesfrom oak and the least when we used particles from spruce. After sanding surface roughness decreased with increased density

Keywords:particleboard, spruce, beech, oak, poplar, surface roughness, sanding, density profile
