Because the super powder particles to be prepared are microscopic materials, mostly nano-, sub-micron or micron-scale powders, the formed particles are small in size, very fast in formation, and very high in temperature. Although the technical principle of forming is simple, the actual It is very difficult to use. It is more difficult to prepare powder particles with uniform particle size, stable morphology and good dispersion that can be used in batches.
常用方法包括扩口结构，让蒸气流动速度放慢然后去控制粒子成形；或是吹气冷却结构，让蒸气快速冷却。两种方法存在气流内外层温度不均匀的缺陷，或存在吹气进气内层导致内部流态不均匀的缺陷，都会导致大量超小与超大颗粒的出现，粉体品质不良，严重影响超微粉体的后续使用。Common methods include a flared structure, which slows the flow of the vapor to control particle formation, or a blow-to-cool structure, which allows the vapor to cool quickly. The two methods have the defect of uneven temperature of the inner and outer layers of the air flow, or the defect of the uneven internal flow state caused by the blowing of the air and the inner layer, which will lead to the appearance of a large number of ultra-small and ultra-large particles, and the powder quality is poor, which seriously affects the ultra-fine particles. Subsequent use of the powder.
