摘 要:
采用静态法测定竹炭在温度为15℃和25℃、相对湿度为65％、75％、85％、95％时的平衡吸湿量，研究炭化温度、粒度、比表面积、吸附温度等因子对其平衡吸湿量的影响，结果表明：竹炭吸湿解吸过程中存在“滞后”现象。700℃、1000℃条件下烧制的竹炭的吸湿效果优于其他炭化温度下烧制的竹炭；粒度大小对竹炭吸湿量的影响很小；比表面积对竹炭的吸湿量有影响；随着环境温度的升高，竹炭吸湿能力降低。[著者文摘]

Abstract:
The equilibrium absorption content was measured in different conditions by static method. The relations between the pyrolysis temperature, the size of bamboo charcoal particle, absorption temperature and the surface area were studied. The results showed that two kind of bamboo charcoal whose pyrolysis temperature were 700 ℃ and 1000 ℃ had the best absorbing ability. The size of bamboo charcoal particle had little influence on absorption. The ability of absorption could be decreased as the environmental temperature increased. The phenomena of moisture absorption hysteresis were found during moisture desorption and absorption.[著者文摘]
