METHOD FOR PREPARING MICROCAPSULES CONTAINING PURE POLYAMINE AND MICRODROPLET GENERATOR THEREFOR

摘要

A method for preparing microcapsules containing a pure polyamine and a microdroplet generator therefor. The method comprises the following steps: providing a reaction solution and stirring the same; generating polyamine microdroplets and adding the same into the reaction solution; obtaining primary microcapsules; washing the primary microcapsules with a washing agent; and obtaining finished microcapsules after drying. The microdroplet generator comprises: a thick teflon tube (2); a thin teflon tube (3) inserted into any parts of the thick teflon tube (2) except front and rear ends thereof; and pump devices (1) separately connected to the thick teflon tube (2) and the thin teflon tube (3).
