  • Patent number: 11577110
    Abstract: Inert and hydrocarbon gases, such as propellant gases, maintain a pressure in a bottle to ensure that a formed composition can be dispensed to an intended destination. The carrier releases soluble hydrocarbon gases and the water drops dissolve inert gases, so the liquid is inflated and creates upstanding foam. This foam maintains the texture and water content up to 6-24 hours, depending on the ratio of the fire-resistant component. As heat reaches the foam, the heat-resistant silicate component becomes activated. Strong heat causes evaporation of the moisture of the carrier, and then the bound water of the silicates evaporates from the foam, with a honeycomb-structure left behind which is a good thermal insulator and is able to protect the object. Above approximately 350° C., a ceramic protective layer forms, while the water content of the foam inside the foam migrates outwards towards the dry crust.

  • Patent number: 11202930
    Abstract: A fire extinguishing equipment including an extinguishing-launching part-unit and a pressure-resistant storage body with an internal space housing a fire extinguishing material. A transport pipe is connected to the internal space to transport the fire extinguishing material to a use location. An extinguishing part-unit is connected to the external end of the transport pipe and includes one or more event-detecting part-units, which are connected to the extinguishing-launching part-unit. The extinguishing-launching part-unit is supplemented with a separation fitting disposed within the transport pipe, separated from a transport regulation fitting also disposed within the transport pipe. A reference pressure supply part-unit is within the transport pipe between the separation fitting and the transport regulation fitting.

  • Patent number: 11202927
    Abstract: A fire extinguishing equipment with improved characteristics which includes a pressure-resistant storage body with an internal space that houses a fire extinguishing composition. A monitoring unit is connected to the storage body to measure and regulate one or more physical characteristics. At least one discharge outlet is in communication with the internal space of the storage body and is configured to discharge the fire-extinguishing composition from the internal space to a use location. A charging inlet is disposed within the storage body and is configured to fill the internal space with the fire-extinguishing composition. An extinguishing-launching part-unit is inserted into a pipe section between the use location and the discharge outlet.
