What material is the explosion-proof door made of? What are the performance characteristics and functions?

The explosion-proof door is a special steel door made of steel plate as the door leaf, with an internal skeleton made of steel pipes and filled with fireproof rock wool.

Explosion proof doors are exterior doors of buildings that can withstand potential explosions from the outside world, including single door, double door, and secondary door, all made of explosion-proof steel.

Explosion proof door is mainly composed of door frame, door leaf, door hinge, door closer, handle lock and linkage bolt lock. There are door stops on the inner perimeter of the door frame, and there are also middle stile fixing blocks on the upper and lower crossbeams of the double door frame. The middle stile is detachable, and the upper and lower ends of the middle stile are connected to the fixing blocks on the crossbeam with connectors. There are also door stops on both sides of the middle stile; The door leaf is welded from the leaf frame, the leaf rib, the door panel and the door inner plate. One side of the door leaf is assembled with the door frame by hinges. The upper end of the door leaf is equipped with a door closer. The door leaf is equipped with a handle lock and a three-way linkage bolt lock; Both doors of the double door are equipped with interlocking bolt locks; The mother door of the child and mother doors is equipped with a linkage bolt lock, while the child door is not equipped with a lock, only with a fixed pressure plate.

It is necessary to prevent buildings with potential explosion hazards from the outside world. For example, using ordinary steel doors under the action of explosion shock waves is difficult to withstand the pressure of explosion shock waves, which can cause long-term deformation and even damage the door leaf structure. It cannot guarantee the safety of personnel inside the building and the integrity of equipment inside the building in the event of an explosion. Explosion proof door is a type of explosion-proof door that is resistant to explosion, penetration, fire, and good airtightness.

The explosion-proof door is composed of a door frame, a door leaf, a door hinge, a handle lock, and a three-way linkage bolt lock. The characteristic is that the door stop on the inner periphery of the door frame is equipped with grooves, and rubber sealing strips are embedded in the groove of the door stop; Install reaction blocks in the middle of the door frame on the same side as the upper and lower hinges; The frame of the door leaf is composed of square angle pipes for the frame, and rectangular pipes for the rib welding. The cavity formed by the frame is filled with flame-retardant materials. The thickness of the door leaf panel is 3mm, and the thickness of the door leaf inner plate is 2mm. Anti smoke strips are pasted on the four sides of the door leaf; The upper hinge seat is equipped with aligning ball bearings, while the lower hinge seat is equipped with aligning ball bearings and thrust ball bearings; The upper latch component of the linkage latch lock of the door leaf is equipped with a self closing hook, and the door stop opposite the self closing hook is equipped with a limit collision block of the self closing hook.

The characteristic of explosion-proof doors is that the panels are made of steel plates coated with high-temperature and corrosion-resistant coatings. A lightweight rubber filled longitudinal impact resistant sandwich composite structure is used between the panels, and a shock absorbing structure is used in the middle to absorb or attenuate impact energy during explosion. While reducing the quality of explosion-proof doors, it also has good shock absorption, sound insulation, and heat insulation effects, thereby improving the ability to resist explosion and impact.
