U cilju dobijanja vatrootpornih furnirskih ploča od različitih drvnih sirovina, u ovom istraživanju topolovi furniri su impregnisani rastvorima izabranih vatrootpornih sredstava, a to su: diamonijum fosfat (DF), monoamonijum fosfat (MF), natrijum acetat (NA), vodeno staklo (VS), natrijum tetraborat (NT) i borna kiselina (BK). Da bi se preliminarno odredio dostignuti nivo vatrootpornosti još kod furnira, pre izrade gotovih ploča, primenjene su termogravimetrijska (TG) i derivativna termogravimetrijska (DTG) metoda. TG i DTG analize za tretirano i netretirano drvo kao i za sama vatrootporna sredstva su izvedene na Perkin-Elmer TGS-2 termogravimetrijskom uređaju. Vatrootpornost ploča je testirana prema standardnom testu otpornosti prema dejstvu vatre i kao najefikasnija sredstva su se pokazala isto NT i BK kao i kod TG/DTG analiza, što ukazuje na validnost termogravimetrijske metode u predviđanju uspešnosti vatrootpornog sredstva u budućem proizvodu.
In the aim to achieve fire-resistant plywood of different wood species, in this study, veneers have been impregnated with solutions of chosen fire retardants, which are diammonium phosphate, monoammonium phosphate, sodium acetate, water glass, sodium tetraborate and boric acid. To determine the preliminary level of fire retardancy achieved in veneers before manufacturing of finished plywood, thermogravimetric (TG) and derivative thermogravimetric (DTG) methods are used. TG and DTG analyses of treated and untreated wood, as well as of fire retardants alone, were performed on a Perkin-Elmer TGS-2 thermogravimetric equipment. Fire resistance of plywood was tested in accordance with standard test for resistance to the effects of fire and the most efficient fire retardants, sodium tetraborate and boric acid had the same results as TG/DTG analyses, which points out the validity of TG methods in predicting success of fire retardants in future products.
