Fire Extinguishing Patch

　　 1. Fire Extinguishing Principle

　　The fire extinguishing patch uses environmentally friendly extinguishing agents, catalysts, stabilizers, and other materials, encapsulated within a nanometer-thin film through a special precision process. It is manufactured into an assembly of automatic fire extinguishers with diameters ranging from 20 to 50 nanometers. Together with an RFID passive tag, it is processed into a micro intelligent fire extinguishing device in the form of a self-adhesive sticker — the fire extinguishing patch. When the front of the patch encounters an open flame and the nanocapsules sense the temperature reaching the designed activation temperature, the capsule shell ruptures, releasing the internal extinguishing agent. It can extinguish fires within 10-30 seconds in relatively enclosed small spaces under 180 cubic decimeters such as distribution boxes, cable trays, cabinets, switches and sockets, battery storage and transport boxes, etc. It can also detect the fire location through the Internet of Things, representing a revolutionary advancement in early-stage fire extinguishing. It is widely applicable in aerospace, transportation, military, civilian, and many other fields. The product is economical, environmentally friendly, durable, stable, fast-acting, and leaves no residue.

　 　2. Application Scenarios

　　For many years, electrical fires have consistently been a major source of fire incidents. These sources are mainly concentrated in distribution boxes, distribution cabinets, battery packs, cable trays, battery casings, computer cases, embedded socket boxes, sockets, and electrical appliances.

　　These small-space electrical fire sources share a basic characteristic: the space is relatively small or even extremely small and enclosed. Early-stage fires are difficult to detect, and once detected, they develop rapidly and cause significant harm.

　　Therefore, automatic fire extinguishing in extremely small spaces has always been challenging. Although there are some compact automatic fire extinguishing devices on the market, they still cannot be installed in extremely small spaces, limiting the application scenarios of automatic fire extinguishing devices, which is a very troublesome problem.

　　The emergence of container-free nano-level microcapsule fire extinguishing material — the fire extinguishing patch — fills the gap in automatic fire extinguishing for extremely small spaces. It advances fire extinguishing to the earliest stage, greatly shortening extinguishing time, enhancing reliability, and minimizing fire risks and losses. It solves the global challenge of rapid early-stage fire suppression in small spaces ranging from 0.001 to 180 cubic decimeters. The application of fire extinguishing microcapsules is the future trend in fire extinguishing materials and equipment.

　　This series of products is suitable for internal fire extinguishing applications in the aforementioned smaller spaces. The fire extinguishing patch can also extinguish gas fires where the gas source has not been cut off.
