TECHNICAL FIELD
[0001] The utility model relates to fire extinguishing equipment technical field, concretely relates to a perfluorocyclohexanone big capsule fire extinguishing device. BACKGROUND
[0002] Among various disasters, fire is one of the main disasters that most frequently and most commonly threaten public safety and social development, and common fire extinguishing substances include dry powder extinguishing agents such as ammonium phosphate salt dry powder, sodium bicarbonate dry powder, D-class dry powder, and ultra-fine dry powder with smaller particle size; liquid extinguishing agents mainly based on water or other liquids such as water, aqueous solution, foam, biological protein extinguishing agent, and ultra-fine water mist extinguishing agent; gas extinguishing agents such as CO2, N2 inert gas extinguishing agent, heptafluoropropane extinguishing agent, and thermal aerosol extinguishing agent rapidly developed in recent years. These extinguishing agents each have its specific use occasion, but all have a relatively large volume, not only requiring a large storage space, but also having limitations in spraying distance and requiring close-range fire extinguishing, which has certain safety hazards. Therefore, the prior art provides many solutions, for example, CN202011505486.6 discloses a gas-liquid mixed automatic fire extinguishing capsule type device, which divides the inner cavity of the shell into two chambers and sets a connecting hole filled with a sealing block between the chambers, and controls the heating of the heater by the starting control panel to obtain the temperature change in the fire site, so as to realize the functions of automatic fire extinguishing and fire suppression of the gas-liquid mixed automatic fire extinguishing capsule type device. However, with the progress of high polymer science, various polymerization mechanisms and polymerization technologies have emerged, and microcapsule technology has been applied in the field of fire fighting.
[0003] The microcapsules synthesized by the prior art have the following shortcomings: the microcapsule fire extinguishing material is usually applied in the interior of equipment, and the temperature during equipment operation may reach 80℃, so the microcapsule fire extinguishing material requires that the microcapsule remains stable within 80℃ and can be triggered rapidly above 100℃. In specific application, an independent granular perfluorocyclohexanone capsule (here, the independent microcapsule refers to the ability to stably exist independently in the air within a certain temperature range, rather than existing as an independent particle in a liquid) is usually required, so that the final form of the fire extinguishing material can be customized according to the application scene, which requires not only that the microcapsule be made into an independent particle, but also that the particle have a long service life at 80℃, so the requirements for the structure and strength of the material are higher. In practice, although microcapsules with a size of less than 1000 um can also exist independently, the capsule wall material needs to have a certain thickness to provide sufficient strength to enable the microcapsule to remain stable under the conventional machine operation condition of 80℃. Under the premise of stable wall material, the content of perfluorocyclohexanone in the microcapsule is very low, usually only 10-30%, which cannot provide effective fire extinguishing capacity.
