Description
Technical Field
The utility model relates to a radiation protection prevents fire door.
Background
A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. It is a fire-proof partition with certain fire resistance, which is arranged in fire-proof subareas, evacuation staircases, vertical shafts and the like.
The fireproof door has the functions of a common door, has the functions of preventing the fire from spreading and the smoke from diffusing, and can prevent the fire from spreading within a certain time to ensure the evacuation of people.
However, most fireproof doors in the market cannot protect against radiation, and for some important places with radiation pollution, once a fire disaster happens, the relevant passage of the place is automatically closed in time, so that a serious radiation pollution accident can be caused, and serious economic loss is caused.
