3 Test methods
3.1 Measurement of moisture
0.05g (accurate to 0.0002g) of sample 5 with particle size less than 0.2mm, which is evenly stirred, is quickly weighed with a weighing bottle which has been dried to constant quality in advance, and spread evenly in the weighing bottle. Open the weighing bottle containing the sample and put it in a drying oven at 105°C- 110°C for drying. After 2h, take out the weighing bottle and cover it immediately, put it in a dryer and cool it to room temperature (about 20min), and weigh it.
