[交流] 通过热重分析表征干燥动力学

Moisture content is an important property of many materials used in chemical reactions or processes since moisture levels that are too high or too low may adversely effect performance and reliability. In addition, drying usually increases production costs. Manufacturers must, therefore, ensure that materials are dried using the optimum conditions of time, temperature and atmosphere. Thermogravimetric analysis (TGA) which measures weight changes in a material as a function of temperature and time provides a convenient method for predicting optimum drying conditions. This is illustrated here for black powder (gun powder). However, the method used is perfectly general and may be used for many solid state decompositions.
