Problems solved by technology

[0002] With the rapid development of social economy, there are more and more urban high-rise buildings used for people's daily life, such as office and residence, and high-rise buildings stand everywhere, forming a landscape of urban buildings; but the hidden safety problems are also increasing. increasing, affecting people's daily life

Although high-rise buildings are equipped with fire-fighting equipment, sometimes due to reasons such as untimely discovery of the fire, the fire cannot be effectively controlled in a timely manner. Escape through escape devices such as stair passages, soft ladders, or slow descenders installed in a certain position of a high-rise building. However, before the disaster, the crowd was in a panic, especially for the elderly, weak, sick, disabled, and children. In the process of the method, the escape channel is often not smooth due to crowding and other phenomena, and even a stampede occurs during the escape process, resulting in casualties, which not only affects the normal operation of the above escape methods, but also fails to achieve a good escape effect. Escape time is wasted in vain; similarly, the use of high-altitude flying equipment, whether it is hot air balloons, Ferris wheels, etc. for entertainment, or aircraft used as traffic grounds, is also increasing the catastrophic time. Due to its high-altitude operation, its escape method and escape time are limited in the face of a catastrophic event escape, and the use of a parachute will take a lot of time. Equipment and devices that facilitate escape from heights need to be continuously developed

[0003] Most of the escape devices used in existing high-rise buildings are used for fire situations, especially the escape devices using escape channel bags. The escape channel bags must not only have excellent fire resistance, but also have excellent heat insulation properties, otherwise The external heat enters the escape passage bag, and the persons involved in the escape passage bag will be extremely hot and uncomfortable in the escape passage bag, which greatly increases the discomfort of the persons involved in the escape passage bag. Therefore, there is an urgent need for a certain fireproof Function, but also has excellent heat insulation effect, and also has high strength, aging resistance, light and thin new composite material
