Description
Technical Field
The invention belongs to the field of microcapsule preparation equipment, and particularly relates to flame-extinguishing microcapsule preparation equipment.
Background
The flame extinguishing microcapsule technology is an innovative fire extinguishing material treatment mode, and utilizes advanced microencapsulation technology to wrap traditional fire extinguishing agents (such as dry powder, liquid fire extinguishing agents and even precursors of gas fire extinguishing agents) in one or more layers of micron-sized shells to form a tiny capsule structure. The core advantage of this technology is that the microencapsulated fire extinguishing agent can rapidly release its active ingredients under specific conditions (e.g., thermal stimulation, mechanical force rupture, or chemical triggering), achieving an accurate, efficient, and controllable fire extinguishing effect.
The microencapsulated fire extinguishing agent not only improves the stability of the fire extinguishing agent and prolongs the storage life, but also can better penetrate into the fire source during the use process due to the characteristics of the tiny size and controllable release, effectively inhibit and isolate the fire source, and is particularly suitable for fire situations which are difficult to directly touch or rapidly spread, such as forest fires, electrical equipment fires and fire alarms in certain enclosed spaces.
Although the microencapsulated fire extinguishing agent has significant advantages, the preparation process is relatively complex, and generally involves precise material proportioning, efficient emulsification and dispersion techniques and stable solidification and molding steps.

Based on the above, the invention provides a flame-extinguishing microcapsule preparation device.
