【摘要】：隨著我國經(jīng)濟的不斷發(fā)展,人們物質(zhì)文化生活水平的不斷提高,人們對生活、工作、娛樂的環(huán)境條件、要求也越來越高,追求高雅、美觀、舒適、潔凈的室內(nèi)環(huán)境已成為一種社會潮流。大到商場、市場,小到賓館、飯店、網(wǎng)吧、KTV、酒吧以及家庭住宅,幾乎所有的建筑都要使用材料裝修,而且越來越高檔、豪華、氣派。在室內(nèi)裝飾裝修過程中,木質(zhì)板材以其淳樸自然、紋理美觀、吸音隔熱等優(yōu)點,在室內(nèi)裝修裝潢和家具的制造過程中得到廣泛的使用,這在一定程度上增大了室內(nèi)的火災(zāi)荷載,對室內(nèi)火災(zāi)的發(fā)生和發(fā)展起著重要的作用,給建筑物室內(nèi)的防火安全埋下了火災(zāi)隱患。因此,研究常見室內(nèi)裝修板材的燃燒性能,對室內(nèi)火災(zāi)的發(fā)生、發(fā)展、蔓延有著重要的意義,正確對常見裝修板材的燃燒性能進行認識和評價,對評價某一建筑的火災(zāi)危險性和消防安全設(shè)計起著十分重要的作用。 錐形量熱儀作為中小尺寸實驗,它與傳統(tǒng)的實驗方法如極限氧指數(shù)法、UL94(水平燃燒和垂直燃燒法)等相比,與真實火災(zāi)環(huán)境更為相似,它的實驗數(shù)據(jù)與大型實體實驗有很好的相關(guān)性,它以耗氧原理為理論基礎(chǔ),即可燃材料每消耗單位質(zhì)量的氧,放出的熱量都大致相同,約為13.1MJ。本文利用錐形量熱儀,選取室內(nèi)裝飾裝修過程中常用的實木板、多層板、高密度板、中密度板等6種板材進行實驗,根據(jù)實驗所測得的熱釋放速率、質(zhì)量損失速率、引燃時間、生煙速率、CO/CO2產(chǎn)率等燃燒參數(shù)對選取的幾種板材的燃燒性能進行了深入的分析研究,在相同熱輻射強度下對比分析了幾種板材的相對燃燒性能,然后又針對不同的熱輻射強度對各燃燒參數(shù)的影響進行了實驗。 實驗結(jié)果表明：在熱輻射強度35 kW/m2下,根據(jù)實驗所得燃燒參數(shù)對選取的幾種板材的燃燒性能進行綜合分析評價,發(fā)現(xiàn)實木板無論是熱釋放速率還是生煙速率、質(zhì)量損失速率、CO產(chǎn)率,都要優(yōu)于其他幾種板材,火災(zāi)危險性較��；在不同熱輻射強度下(25 kW/m2、35 kW/m2、50 kW/m2),分析了熱釋放速率、生煙速率、CO產(chǎn)率等隨熱輻射強度的變化情況,發(fā)現(xiàn)隨著輻射強度的增大,板材的熱釋放速率、生煙速率、CO產(chǎn)率等都隨著增大,且各曲線出現(xiàn)峰值的時間也隨著輻射強度的增大而提前。此外在考察熱輻射強度對引燃時間的影響時發(fā)現(xiàn).引燃時間的均方根倒數(shù)與熱輻射通量呈線性關(guān)系,得到線形擬合方程以及擬合度,擬合度均在0.97以上。
[Abstract]:With the continuous development of our economy and the constant improvement of people's material and cultural living standards, people have higher and higher demands on the environmental conditions of life, work and entertainment, pursuing elegance, beauty and comfort.Clean indoor environment has become a social trend.From shopping malls, markets, small hotels, restaurants, Internet cafes, bars and family homes, almost all buildings are decorated with materials, and increasingly upscale, luxurious, and stylish.In the process of interior decoration and decoration, wood panels are widely used in the process of interior decoration and furniture manufacturing, because of their simple nature, beautiful texture, sound absorption and heat insulation, which to a certain extent increase the indoor fire load.It plays an important role in the occurrence and development of indoor fire.Therefore, it is of great significance to study the combustion performance of common indoor decoration panels, which is of great significance to the occurrence, development and spread of indoor fire.It plays an important role in evaluating fire hazard and fire safety design of a certain building.The conical calorimeter, as a small and medium size experiment, is more similar to the real fire environment than the traditional experimental methods, such as the limit oxygen index method (UL94) and the horizontal and vertical combustion method.Its experimental data are well correlated with large scale solid experiments. It is based on the principle of oxygen consumption. The heat released by combustible materials per unit mass of oxygen is approximately the same as that of 13.1 MJ.Combustion parameters such as smoke generation rate, CO / CO _ 2 yield and so on, were used to analyze the combustion performance of selected plates, and the relative combustion properties of several plates were compared and analyzed under the same heat radiation intensity.Then the effects of different thermal radiation intensity on the combustion parameters were studied.The experimental results show that under the condition of 35 kW/m2 of thermal radiation intensity, the combustion performance of the selected plates is analyzed and evaluated comprehensively according to the combustion parameters obtained from the experiment, and it is found that the heat release rate and smoke generation rate of the solid plank are not only the heat release rate, but also the smoke generation rate.The CO yield of mass loss rate and CO is superior to that of other planks, and the fire risk is relatively low. Under different thermal radiation intensities, the variation of heat release rate, smoke generation rate and CO yield with thermal radiation intensity is analyzed, and the heat release rate and smoke rate are analyzed, and the thermal radiation intensity varies from 25 kW / m ~ (2) to 35 kW / m ~ (2) / m ~ (2) ~ (2) to 50 kW / m ~ (2) / m ~ (2).It is found that with the increase of radiation intensity, the thermal release rate, smoke generation rate and CO yield increase with the increase of radiation intensity, and the time of peak value of each curve is also advanced with the increase of radiation intensity.In addition, the influence of thermal radiation intensity on ignition time was investigated.The RMS reciprocal of ignition time is linearly related to the heat radiation flux. The linear fitting equation and the fitting degree are all above 0.97.
