Abstract

Veneer plate was painted by the treatment with ammonium salts such as ammonium chloride (AMCR), ammonium sulfate (AMSF), monoammonium phosphate (MAPP), and diammonium phosphate (DAPP) at room temperature. The flame retardancy of painted veneer plate was investigated. The painted veneer plate shows an increased $CO/CO_2$ over virgin veneer and it was supposed to affect the toxicity to different extents. But when the ammonium salts were used as the retardant for veneer, the flame retardancy was improved due to the painted ammonium salts in the veneers. Also, the veneer plates with ammonium sulfate and ammonium chloride showed both the lower total smoke release (TSR) and lower total smoke production (TSP) than that of virgin veneer.

실온에서 베니어에 ammonium chloride, ammonium sulfate, monoammonium phosphate, 그리고 diammonium phosphate와 같은 암모늄염으로 도포하고, 도포된 베니어의 난연성을 조사하였다. 암모늄염으로 도포된 베니어판은 미처리된 순수 베니어판에 비하여 $CO/CO_2$비를 증가시켰다. 이것은 정도에 따라 독성에 영향을 미치는 것으로 생각된다. 암모늄염이 베니어의 난연제로 사용되었을 때, 도포된 암모늄염은 베니어의 난연성을 향상시켰다. 또한 ammonium sulfate와 ammonium chloride로 도포된 베니어는 미처리된 순수 베니어에 비해 양쪽 모두 낮은 총연기방출율과 낮은 총연기량을 나타내었다.
