通过单轴压缩试验,研究了含水率和循环加湿卸载对三种不同类型沸石颗粒强度等力学性能的影响。用不同的粘结剂含量和不同的热干燥/活化温度对所测试的颗粒进行处理。润湿-干燥循环包括在气候室中用湿空气润湿颗粒,并完全浸泡在水浴中,然后在350-400℃的干燥室中进行热干燥。对实验记录的力-位移曲线和扫描电子显微镜记录的颗粒和断口的数字图像进行了评估和讨论。随着润湿-干燥循环次数的增加,由于结构的非再生损伤,颗粒的强度不断下降。然而,经过十次循环后,几乎达到了一个临界恒定的强度水平。
The influence of moisture content and cyclic moisture loading and unloading on the mechanical properties like the strength of three different types of zeolite granules has been studied by uniaxial compression tests. The tested granules had been processed using different contents of binder and different thermal drying/activation temperatures. A moistening–drying cycle consists of moistening the granules in a climate chamber using wet air and complete immersion in a water bath followed by thermal drying in a drying chamber at 350–400 °C. The experimentally recorded force–displacement curves and digital images of the granule and fracture surfaces recorded using scanning electron microscopy are evaluated and discussed.With increasing number of moistening–drying cycles, a continuous decrease in the strength of granules take place due to non-regenerative damage of the structure. However, a critically constant strength level is more or less reached after ten cycles.
