The fireproof material refers to various materials which play an absolute role in modern fire prevention and are mostly used for buildings. Commonly used fire-resistant materials include fire-resistant panels, fire-resistant doors, fire-resistant glass, fire-resistant paint fire-resistant bags, and the like. The fireproof door is a door which can meet the requirements of fire-resistant stability, integrity and heat insulation within a certain time, and is a fireproof partition which is arranged between fireproof partitions, evacuation staircases, vertical shafts and the like and has certain fire resistance.
The fireproof door has the function of a common door, and can prevent the fire from spreading within a certain time to ensure the evacuation of people. When a fire disaster occurs, the life of people is threatened, the fire is high in temperature, smoke emitted by object burning is generated, and according to statistics, more than 80% of death people in the fire disaster die due to suffocation of the smoke.
In theory, the fire door needs to be kept closed, but in the practical use process, because various human factors, people often open the fire door and forget to close, the fire door is in an open state, when a fire disaster happens, because the fire door is in the open state, smoke can pass through the fire door and gush to an escape passage, and therefore people are influenced to escape, and the safety performance is low. Therefore, we propose a pneumatic type safety fire door of the type of surely blocking smoke.
