20.500.12556/RUL-616 Vpliv premaznih sistemov na trdoto lesenih talnih oblog diplomski projekt The influence of coating systems on the hardness of wood floorings B. Sc. thesis Današnji kupci vse več posegajo po površinsko že obdelanih lesenih talnih oblogah. Njihova življenjska doba je v veliki meri odvisna od trdote površine. Na 33 površinsko obdelanih vzorcih parketa s slovenskega tržišča smo ugotavljali, koliko na trdoto vpliva podlaga in koliko premazni sistem. Trdoto premazanih vzorcev smo izmerili po Brinellu (SIST EN 1534:2003), na napravi Zwick Z100. Nato smo vzorce poskobljali, da smo odstranili premaz in meritve izvedli ponovno. Rezultati so pokazali, da premazi v večini primerov nimajo prevladujočega ali zelo velikega vpliva na trdoto površin lesenih talnih oblog. Glede na trdoto podlage pod plastmi premaznega sistema je bil delež povečanja ali zmanjšanja trdote zaradi premaza do približno 10 %, nekaj vzorcev pa je izstopalo, saj smo opazili tudi do 30 % dvig trdote zaradi premaza. Nowadays customers frequently decide to buy completely finished wooden floorings. The lifespan of such floorings mostly depends on the hardness of their surface. 33 samples of finished wooden floorings that were obtained from the Slovene market were tested to determine how the coating system influences the surface hardness of the flooring. The Brinell hardness of the samples with coating systems was determined with the SIST EN 1534:2003, using the Zwick Z100 instrument. Afterwards we planed the samples to remove the coating and re-measured the hardness. The results showed that in most cases the coating does not greatly or significantly contribute to the hardness of wood flooring (up to 10 % increase or decrease of hardness was observed in comparison to the hardness of the flooring without any coating). However some samples deviated substantially from this common rule, with the coating layer increasing the hardness of the flooring by up to 30 %. parket površinska obdelava trdota parquet flooring surface finishing hardness true false false [J.
