摘要： A method for evaluating the powder dispersibility including dispersing a powder allowed to stand inside a closed container by mechanical vibration applied quantitatively to the powder; collecting the dispersed powder on a quartz crystal element or a piezo element; and measuring the mass of the collected powder using a quartz crystal microbalance or a piezo element mass meter to thereby measure the airborne powder concentration in air inside the closed container; a method for evaluating airborne powder concentration at work place using the method for evaluating the powder dispersibility; and a method for designing a powder containment facility using the method for evaluating airborne powder concentration.
