Abstract

The invention provides a millimeter-level flow control technology-based water-soluble core blast bead preparing method. The millimeter-level flow control technology-based water-soluble core blast beadpreparing method comprise preparing water-in-oil-in-water (W/O/W) emulsion drops through a three-dimensional confocal channel, wherein the internal phase of the drops is water soluble core solution,the intermediate phase of the drops is uncured wall material precursor, and the external phase of the drops are aqueous solution containing surfactant; performing wall material curing and blast bead encapsulation in a photocuring manner. The millimeter-level flow control technology-based water-soluble core blast bead preparing method is simple in applied equipment, low in production cost and highin encapsulation efficiency and can prepare millimeter-level water-soluble core blast beads uniform in size and diameter and controllable in capsule wall thickness.

Description

technical field [0001] The invention relates to a method for preparing water-soluble core material explosive beads based on millifluidic technology, and belongs to the technical field of explosive beads. Background technique [0002] In recent years, the tobacco industry has shown a development trend of cigarettes with low tar, low harm, and high aroma. When meeting the demand for low-tar cigarettes, it also faces the problem of insufficient aroma. Therefore, it is necessary to add aroma in cigarette production. Cigarette manufacturers at home and abroad have developed many flavoring technologies, such as flavoring shredded tobacco, flavoring cigarette paper, and flavoring packaging materials. The filter flavoring method has unique advantages because it can avoid the loss and thermal decomposition of flavors during cigarette storage and smoking, reduce the interception of flavors by shredded tobacco, and increase the utilization efficiency of flavors. [0003] The method of...
