海泡石应用于调湿材料的研究

The application of sepiolite as humidity-controlling materials

为寻找合适的湿度调节材料,本文对海泡石及海泡石复合样品进行了吸湿能力和放湿能力测试。与坡缕石比较,10g200目海泡石样品可以将10L密闭容器的湿度从70%降至4%,吸湿能力强于同样条件下的坡缕石。海泡石(10g)的吸、放湿能力经过3次吸、放湿实验后有所减弱,最后一次吸湿量达0.4g,放湿量达0.15g。实验还发现,30g海泡石和白水泥复合样品可以使10L容器内部的湿度稳定在40%～50%,因此,海泡石可以用作室内湿度调节的建筑材料。

To find appropriate humidity_controlling material, the authors studied sepiolite and its compound samples for the capacity of moisture absorption and desorption. The relative humidity of a 10 liter glass vessel could be reduced from 70% to 4% by 10g sepiolite, whose moisture adsorption capacity is stronger than that of palygorskite under the same condition. The moisture adsorption capacity of sepiolite (10 g) will somewhat weaken after three circulations of absorbing and desorbing experiments. In the last experiment, the sepiolite (10 g) absorbed about 0.4g moisture and released some 0.15 g moisture. It has been found that 30 g sample of sepiolite compounded with white cement can keep the humidity in the range of 40%～50% in a 10 liter glass vessel. Sepiolite can be used as building materials for indoor air humidity control.
