摘要

The hydration rate of allophane and imogolite has been estimated by means of an adiabatic vapor absorption calorimeter. The hydration amount of allophane and imogolite were 16.6 and 19.4 percent, respectively, at dehydrated temperature of 100 deg C. The maximum hydration rate of allophane and imogolite were 0.063 mmol/g centre dot s and 0.087 mmol/g centre dot s, respectively, at same dehydration temperature. When allophane and imogolite were dehydrated at temperatures below 100 deg C, the hydration rate of allophane as larger than that of Mg-A type zeolite, and the hydration amount of allophane was larger than that of B type silica gel. Both hydration rate and hydration amount of imogolite were larger than those of Mg-A type zeolite and B type silica gel. Therefore, allophane and imogolite are suitable for heat exchange absorbents of the heat pump and speedy drying desiccant.
