该测试首先将粉体材料倒入一个空心圆柱体中,之后在电机的牵引下以0.5m/s的速度对圆柱体向上进行牵引,使其中的粉体自然形成一个堆积角之后进行测量得到角度。重复多次,取平均值。
In this test, the powder material is first poured into a hollow cylinder, and then the cylinder is pulled upward at a speed of 0.5m/s under the traction of the motor, so that the powder in it will naturally form a stacking angle and then the angle is measured. . Repeat several times and take the average value.
