摘要:
为评估棉花的热危险性，采用自热和自燃点测试装置，研究了含水量、含油量、堆积密度等对棉花自热性能的影响规律，以及立方体金属网篮的不同体积对棉花自燃温度的影响。结果表明：含水量、含油量及堆积密度越高，棉花内部温度越高，热危险性越大。但水的质量分数在0~50%的范围内，脱脂棉和长绒棉两种棉花均不属于自热物质；当油的质量分数为5%和10%时，长绒棉发生自燃时最高温度分别为635.6 ℃和539.7 ℃，属于自热物质；当油的质量分数为5%、10%和15%时，脱脂棉最高温度分别上升至161.7、169.8 ℃和184.1 ℃。立方体金属网篮的体积越大，棉花的自燃温度越低；研究发现，立方体网篮体积的对数（logV）和自燃温度的倒数（1/T）成线性关系，根据拟合曲线可预测不同体积下棉花的自燃温度。
Abstract:
To evaluate the thermal hazard of cotton, the effects of different moisture content, oil content and packing density on the self-heating of cotton were studied using self-heating and spontaneous ignition temperature tests. The thermal hazard increases with the increase of the moisture content, oil content and bulk density of the cotton. However, spontaneous ignition doesnt occur for degrease cotton and long staple cotton under the moisture content in the range of 0-50%. With 5% and 10% oil content, the highest temperature of the long staple cotton reaches to 539.7 ℃ and 635.6 ℃, respectively, therefore they are categorized into self-heating substance. When the oil content of absorbent cotton is 5%, 10% and 15%, the highest temperature of the degrease cotton rises to 161.7 ℃, 169.8 ℃ and 184.1 ℃. The larger the volume of the metal basket, the lower the auto ignition temperature of the cotton is. It is found that the logarithm (logV) of the cube basket volume is linearly related to the reciprocal of the auto ignition temperature (1/T). According to the fitting curve, the auto ignition temperature of cotton bale with various volumes can be predicted.
