Beschreibung
Zusammenfassung:	The present invention relates to protection of wooden constructions on their surface to diminish their inflammability. The fireproofing solution claimed consists of sodium and potassium carbonates and increases considerably resistance of wooden constructions to combustion. Combustion of pine timber impregnated with fireproofing solution claimed at 600 oC results in residue of 53 %. According to these results impregnated with fireproofing solution pine timber is classified as B class of combustibility and smoke formation is evaluated as s2 degree. Išradimas gali būti pritaikytas medinių konstrukcijų apsaugai paviršiniu būdu, siekiant sumažinti jų degumą. Šis antipireninis tirpalas yra pagamintas iš natrio ir kalio karbonatų ir žymiai padidina medinių konstrukcijų atsparumą degumui. Pušies medieną 2-3 kartus impregnavus gautu antipireniniu tirpalu (KMP-3) bandinių masės likutis esant 600 oC temperatūrai yra 53 %. Pagal tyrimo metu gautus rezultatus KMP-3 antipireniniu tirpalu impregnuota pušies mediena priskiriama B degumo klasei, o dūmų susidarymo įvertinimo kriterijus yra s2.
