Kvalitet ploča iverica na tržištu Srbije u pogledu emisije formaldehida

Abstract

U ovom radu istražen je trend kretanja emisije formaldehida iz ploča iverica uvezenih na tržište Srbije. Uzorkovanje i ispitivanje ploča iverica obavljeno je u dva vremenski odvojena perioda. Prvi period ispitivanja odvijao se tokom 2011. godine, a drugi tokom 2015-2016. godine. U oba ova perioda, uzorkovane su sirove ploče iverice, poreklom od tri različita proizvođača. Perforator metoda (EN 120) korišćena je za ispitivanje sadržaja formaldehida u uzorcima ploča. Rezultati pomenutih ispitivanja pokazali su da velika većina uzoraka pripada E1 klasi ploča iverica. Pored toga, oko 19 % ploča iverica uzorkovanih u 2011. godini i oko 31 % ploča uzorkovanih tokom perioda 2015-2016. godine imali su sadržaj formaldehida ispod 50 % od zahteva za E1 klasom.

The formaldehyde potential of particleboards imported on Serbian market was evaluated in this research. The sampling and testing of particleboards were conducted in two discrete periods: first was during 2011 and the second was in the period of 2015-2016. For both periods, the samples of raw particleboards originated from three different producers. The perforator method (EN 120) was used to test the formaldehyde content in the particleboard samples. In general, the results have showed that the majority of the samples belong to the E1 class of particleboards. In addition, 19 % of the particleboards sampled in 2011 and 31 % of the boards sampled in 2015-2016 were found to have formaldehyde content below 50 % of E1 class requirements.
