Experiments on the combustion characteristics of untreated wood specimens and also treated ones with boric acid and ammonium pentaborate were carried out using a cone calorimeter according to ISO 5660-1 standard. As a result, comparing to untreated specimen, the fire performance index (FPI) of the specimens treated with boron compounds increased by 1.2 to 2.1 times and the fire growth index (FGI) increased by 1.6 to 8.4%. Also, total smoke release rate (TSR) was 9.0 to 28.3% lower than that of the untreated specimen. It is understood that the test specimens treated with the boron compound produces a carbonized layer with a flame retarding effect. The highest CO concentration, 0.01112%, for the untreated specimen was observed at 418 s, but the specimens treated with boron compound decreased 13.2 to 37.5% compared to untreated specimen. Therefore, wood treated with boron compounds is expected to have lower fire hazards and risks.

“…The HRR value in the discharge of the fire retardant-treated wood specimens did not exceed the limit of the standard. The HRR is the main indicator for the risk of flame spread (Grexa and Lubke 2001;Lee et al 2011;Dao et al 2013;Seo et al 2016b). It is also used to evaluate the flame spread on the surface of materials.…”

“…Various types of fireretardant treatments are used for wood. According to previous research, several methods have been used to reduce the flammability of wood and wood-based materials through chemical treatment, including impregnating a flame retardant inside the wood, applying flame retardant paints onto the surface of wood, or coating a flame-retardant film onto the surface of wooden materials (Chen et al 1999;Grexa et al 1999;Kawamoto 1999;Grexa and Lubke 2001;Seo et al 2016a). The first method involves impregnating the inside of the cell walls of wood (the pit) with flame retardants such as phosphorus, boric acid, silicabased and other inorganic chemicals, or nano-sized flame retardants.…”

Fire Properties of Pinus densiflora Utilizing Fire-retardant Chemicals based on Borated and Phosphorus (I) – Combustion Characteristics

The combustion and thermal characteristics of fire retardant-treated pine (Pinus densiflora) were evaluated according to the KS F ISO 5660-1 (2003) standard, using a cone calorimeter. The specimens were treated with fire-retardant chemical compounds using pressure-impregnation equipment to reliably impregnate the compounds inside the wood. The heat release rate value of the fire retardant-treated wood specimens showed that the heat release time was delayed. A reduction of the total heat release value can indicate that fire was prevented from igniting in the materials during combustion. The microstructures of natural specimen and treated fire-retardant chemical compounds specimen were determined by scanning electron microscopy. It also confirmed that the pressureimpregnation processing method was effective in comparison to the other treatment methods.

“…Generally, the smoke production and toxic gas formation along with the heat release rate play a critical role in fire conditions [6]. One of most toxic gases released from burning wood is carbon monoxide.…”

“…2 also indicates the fact treated samples cannot burn well like virgin wood does. However, the carbon monoxide formation at the expense of carbon dioxide is an important fire retardant principle [6], which means finding methods such as add other synergetic chemicals to inhibit this side effect is also significant. The effect of flame retardant on smoke formation was measured.…”

Abstract. Wood was treated with guanyl urea phosphate (GUP) to impart flame retardant. The flame retarding behavior of samples was valued by cone calorimeter and thermalgravimetric analysis. The flammability parameters, including rate of heat release (RHR), total heat release (THR), total mass loss (TML) and mass loss rate (MLR), yield of CO and CO 2 , smoke production rate (SPR) and total smoke production (TSP) were recorded simultaneously. By analyzing these data, it was concluded that most combustion parameters of wood were decreased by the treatment.
