Preparation method of micron-sized nitro-cotton balls

The invention relates to a preparation method of micron-sized nitro-cotton balls and mainly solves the technical problems the preparation period is long and prepared nitro-cotton balls are low in quality with an existing preparation method of the nitro-cotton balls. In the preparation process, no additives are required, no stirring devices are required, nitro-cotton balls with different nitrogen content can be prepared, and different requirements can be met. The prepared balls have simple composition, have the micron particle size and have the advantages of being small in particle size, narrow in particle size distribution, simple in technology and short in preparation period. 本发明涉及种微米级硝化棉球形药的制备方法，主要解决了现有硝化棉球形药的制备方法存在制备周期长和制备的硝化棉球形药品质低的技术问题。本发明制备过程中不需要任何添加剂，不需要搅拌装置，可制备不同含氮量的硝化棉球形药，满足不同需求。制备得到的球形药组成简单，球形药粒径在微米级，具有粒径小、粒径分布窄、工艺简单、制备周期短的优点。
