"超微粉" 从物理学角度来说将粒径为0.1μm以下的粉末称为超微粉。从工程学角度划分人们把0.5μm以下的粉末称为超微粉。其实超微粉的 粒径应是指颗粒在性能上呈现与原固体完全不同的行为时的粒径。早些年有人对中药超微粉进行过概念炒作，只是将中药进行一般的损坏和研磨， 尽管眼观上也是细粉末状态，可是并没有抵达超微粉概念中的标准，不能称作为真正含义上的超微粉。
"Ultrafine powder" refers to the powder whose particle size is less than 0.1 micron as ultrafine powder from the physical point of view. From the engineering point of view, the powders below 0.5 micron are called ultrafine powders. In fact, the particle size of ultrafine powder should refer to the particle size when its performance is completely different from that of the original solid. In the past few years, some people have made conceptual hype about the ultrafine powder of traditional Chinese medicine. They just damaged and grinded the traditional Chinese medicine in general. Although they are in the state of ultrafine powder, they have not reached the standard of the concept of ultrafine powder and can not be called ultrafine powder in real meaning.
中药超微粉是运用世界领先的超声损坏、超低温损坏技术对中药加工成微米甚至纳米级的微粉散剂，能使原生药中心粒径在5～10μm以下，细 胞破壁率抵达95%。药效成分具有良好的溶解性、分散性、吸附性、化学反应活性等易于被动物体直接吸收;超微损坏技术打破了沿用千百年的“药 罐子”，被誉为中药饮片史上的一次具有里程碑含义的革新。
Ultra-fine powder of traditional Chinese medicine (TCM) is a kind of micron or even nano-sized powder powder processed by the world's leading technology of ultrasonic damage and ultra-low temperature damage. It can make the center diameter of the original drug less than 5-10 micron, and the cell wall-breaking rate reaches 95%. Pharmacodynamic ingredients have good solubility, dispersibility, adsorbability, chemical reactivity, etc. They are easy to be absorbed directly by passive objects. Ultra-micro damage technology has broken the "medicine pot" which has been used for thousands of years, and has been praised as a milestone innovation in the history of traditional Chinese medicine pieces.
The Concept of Fineness of Chinese Medicine Ultrafine Powder
According to the size or size of particles in materials and products, the damage can be divided into coarse damage, fine damage, micro damage and ultra-micro damage: the particle size greater than 4 mm (5 mesh) is called coarse damage.
Particle sizes ranging from 4 mm to 150 micron (5-100 mesh) are called fine damage.
Ultra-fine damage is called when the particle size is 150 micron to 50 micron (100-300 mesh). Ultra-fine damage is called when the particle size is less than 50 micron (more than 300 mesh).
In our daily life, the fineness of flour is about 100 meshes, starch is about 120 meshes, maize flour is about 60 meshes, mung bean is about 5 meshes. When the damage fineness of Chinese medicinal materials reaches more than twice of the flour, Chinese medicinal materials break down initially, many effective ingredients dissolve out, and the biological utilization rate is doubled, which is now commonly called cell wall breaking.
