【摘要】：火災(zāi)中,各類裝飾材料成為助燃物引發(fā)更大災(zāi)情,其燃燒后釋放的有毒煙氣也是造成人員傷亡的主要原因。本實驗基于標(biāo)準(zhǔn)ISO 9705小尺寸熱釋放速率實驗臺,利用耗氧原理分別測量厚度為1、2和3 mm的聚氯乙烯(PVC)桌面裝飾材料試樣的熱釋放速率,分析燃燒特性。實驗結(jié)果顯示,邊長為30 cm的矩形試樣能被2 m L的正庚烷引燃,燃燒的最高溫度大于800℃;不同試樣的熱釋放速率最大值隨著厚度的增加而減少,分別為5.82、4.41和2.83 k W/s,但是熱釋放速率總值呈遞增趨勢;隨著試樣厚度的增加,引燃的時間推遲,即引燃的難度增大;材料燃燒過程中釋放大量黑煙和刺鼻的氣味。
[Abstract]:In the fire, all kinds of decorative materials become combustible and cause more disasters, and the toxic smoke released after burning is also the main cause of casualties. Based on the standard ISO 9705 small scale thermal release rate test rig, the thermal release rate of PVC / PVC tabletop decorative materials with thickness of 1mm and 3mm was measured by oxygen consumption principle, and the combustion characteristics were analyzed. The experimental results show that the rectangular specimen with a side length of 30 cm can be ignited by 2 mL n-heptane, and the maximum combustion temperature is more than 800 鈩，
