AB  - Osnovni motiv ovog rada je sve naglašenija potreba za furnirskim pločama otpornim na vatru. U ovom radu, bukovi 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 MF i NT kao i kod TG/DTG analiza, što ukazuje na validnost termogravimetrijske metode u predviđanju uspešnosti vatrootpornog sredstva u budućem proizvodu.
AB  - The basic motive of this work is the ever more pronounced need for fire-resistant plywood. In this work, beech veneers have been impregnated with solutions of chosen fire retardants, which are diammonium phosphate monoammonium phosphate, sodium acetate, water glass, sodium tetra borate and boric acid. To determine the preliminary level of fire retardancy achieved in veneers before manufacturing of finished plywood, thermo gravimetric (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 thermo gravimetric 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 monoammonium phosphate and sodium tetra borate, 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.

AB  - Poslednjih desetak godina, u skladu sa novim standardima i propisima, znatno povećana je potreba za vatrootpornim drvenim konstrukcijama i elementima. S druge strane, evidentan je nedostatak detaljnih istraživanja interakcije između drvnih vrsta, posebno domaćih i izabranih, čak i osnovnih vatrootpornih hemikalija. U ovom istraživanju, bukovi i topolovi furniri su različito vreme impregnisani potapanjem u 25% rastvor monoamoonijum-fosfata (MP) i natrijum-acetata (SA). U cilju preliminarnog određivanja postignute vatrootpornosti u furnirima, pre izrade gotove furnirske ploče, sprovedene su dinamičke metode termalne analize i to: termogravimetrijska (TG) analiza i derivativna termogravimetrijska (DTG) analiza impregniranog i neimpregnisanog drveta kao i samih vatrootpornih sredstava. Za impregnisane i neimpregnisane furnire su takođe određene i sledeće karakteristike absorpcija impregnacionog rastvora (A), maseni procentualni prinos vatrootpornih sredstava (WPG), ravnotežna vlaga (EMC), pH vrednost, a za furnirske ploče još i smicajna čvrstoća i vatrootpornost. Vatroootpornost furnirskih ploča je testirana prema JUS standardu i kao efikasniji se pokazao monoamonijum-fosfat što su pokazale i TG/DTG analize iz čega se može zaključiti da TG metode imaju značajnu ulogu u predviđanju vatrootpornosti budućeg proizvoda.
AB  - Rising demands for fire resistance properties of wood construction and elements matching new standards have been an important part of building codes during the last decade. On the other side, lack of more detailed research on interaction between wood species and selected fire retardant chemicals even with basically one is evident. This is particularly truth with domestic wood species. In this research, beech and poplar veneers were immersed in 25% solutions of monoammonium phosphate (MP) and sodium acetate (SA) and impregnated for different periods of time. To determine the preliminary level of fire retardancy achieved in veneers before manufacturing of finished plywood, thermo gravimetric (TG) and derivative thermo gravimetric (DTG) methods were used. TG and DTG analyses of treated and untreated wood, as well as of fire retardants alone, were performed. The next properties of impregnated and no impregnated veneers and plywood were determined: absorption of imp regnant solution (A), weight percent gain (WPG) of imp regnant, equilibrium moisture content (EMC), pH values, and in the case of plywood, strength and fire resistance. Fire resistance of plywood was tested in accordance with standard test for resistance to the effects of fire and the most efficient fire retardant, monoammonium phosphate, had the same result as TG/DTG analyses, which pointed out the validity of TG methods in predicting fire resistance of future products.
