为了测定油脂棉纱有无自燃的可能、自燃的难易程度,并为火灾原因的判断提供科学依据,广东省公安消防总队与华南工学院化学系协作,开展植物油自燃成因和规律的研究,经过二年多的反复试验,设计了一套模拟自燃现象测定油脂棉纱体系自燃的装置,取得了大量的数据、升温曲线并提出了两个数学模型。植物油,如山苍子油、桐油、豆油、亚麻油等,含有不同程度的不饱和脂肪酸甘油脂,在
In order to determine the possibility of spontaneous combustion of cotton yarn, the degree of spontaneous combustion and provide a scientific basis for the judgment of the cause of the fire, Guangdong Provincial Public Security Fire Brigade collaborated with the Department of Chemistry of South China Institute of Technology to carry out researches on the causes and laws of vegetable oil spontaneous combustion. Repeated experiments for more than a year, designed a set of devices to simulate the spontaneous combustion of the fat cotton yarn system to simulate the spontaneous combustion phenomenon, and obtained a large amount of data, heating curve and put forward two mathematical models. Vegetable oils, such as litsea cubeba oil, tung oil, soybean oil, linseed oil, contain varying degrees of unsaturated fatty acid glycerides, in
