PROBLEM TO BE SOLVED: To solve the problems that various methods have been performed hitherto as methods for producing powder, but every method has such an anxiety that the powder has wide grain diameter distribution, and that smooth powder is difficult to be acquired because the powder tends to have a squarish shape.SOLUTION: In a production method of powder, a thermoplastic polymer is heated into a swollen condition to obtain a molten polymer, and powder is produced from the molten polymer by using Melt ESD system using high-speed air and electric charge. A method therefor is also provided. |
