[0002] Fire doors are a type of door that, in addition to having the functions of ordinary doors, can also prevent the spread of fire and smoke. They can prevent the spread of fire for a certain period of time, ensure the evacuation of personnel, and effectively block the invasion of thick smoke and flames in the event of a fire. Fire doors are important equipment for fire isolation on ships. Their main function is to prevent the spread of fire and protect the lives of crew members when a fire occurs.
[0003] According to Chinese patent application number: 202223585860.5, a single-opening fire door for a ship is disclosed, comprising: a fireproof board, a fireproof window and a fire door, wherein the fireproof board is equipped with a fireproof window, a handle and a fire door, and the edge is wrapped with a frame, the frame is fixed to the fireproof board, the closed space formed by the inner surface of the frame and the inner surface of the fireproof board is filled with a filler, and the filler is wrapped with a hot-melt film and a coolant, and the filler filled in the closed space formed by the inner surface of the frame and the inner surface of the fireproof board is a water-absorbing material, and the internal hot-melt film will melt and rupture when the heating temperature reaches the limit, so that the coolant in the hot-melt film is absorbed by the filler, and the coolant will cool the fireproof board after being absorbed by the filler, thereby further improving the fire prevention effect of the fireproof board, and the fire door facilitates the fire hose to pass through the fire door and enter the fire scene to extinguish the fire, which is more practical and suitable for wide promotion and use;
