Embodiment 1
[0046] An emergency or preventive disposal bag for lithium batteries and electronic equipment containing lithium batteries, including a bag body, the bag body sequentially includes a fire-extinguishing gel layer, a heat-resistant and explosion-proof layer from the inside to the outside, and the fire-extinguishing gel layer includes a plastic film Made of pouches, the pouches are filled with propellant-containing fire extinguishing gel, or are provided with a fire extinguishing gel release point on the inner side of the plastic film on the inner surface of the pouch; when the ambient temperature exceeds the gel release point, the rupture When the temperature is high, the gel flows out of the gel bag from the release point, and after contact with lithium batteries or devices containing lithium batteries, it plays the role of reducing the temperature of lithium batteries, blocking thermal runaway, and reducing the danger of smoke and fire. When the temperature exceeds the heat dis...
Embodiment 2
[0048] An emergency or preventive disposal bag for lithium batteries and electronic equipment containing lithium batteries, characterized in that it includes a bag body, and the bag body sequentially includes a fire-extinguishing gel layer and a heat-resistant and explosion-proof layer from the inside to the outside. The layer includes a pouch made of plastic film, the pouch is filled with fire extinguishing gel containing propellant, or a fire extinguishing gel release point is provided on the inner side of the plastic film on the inner surface of the pouch; when the ambient temperature exceeds the gel At the breaking temperature of the release point, the gel flows out of the gel bag from the release point, and after contacting with lithium batteries or devices containing lithium batteries, it plays the role of reducing the temperature of lithium batteries and blocking thermal runaway, reducing the risk of smoke and fire. danger. When the temperature exceeds the heat distorti...
Embodiment 3
[0067] A lithium battery heat insulation, cooling, flame retardant and explosion-proof emergency or preventive disposal packaging bag, the gel film is polyethylene (PE) / polyamide (PA), or PE / PA multi-layer co-extruded film , the width of the strip chamber is 2cm, the width of the heat-sealing bonding seam is 3mm, the width of the communication channel 4 between each strip chamber is 5mm, the gel film strip chamber 3 shares the liquid inlet channel 1, and the fire extinguishing gel Inject into the strip cavity of the gel film through the common liquid inlet channel, and heat seal the heat-sealed edges 5 along both sides of the gel film to form a bag-shaped inner bag 9 .
