(Summary description)Regardless of the opening direction of the door, the door is automatically and completely closed. Therefore, it can reduce heat loss, reduce dust intrusion, increase air tightness, and save energy. And cooperate with the negative pressure air conditioner of the operating room to reach the airtight standard of the operating room.

The working principle of airtight door:
1: Regardless of the opening direction of the door, the door is automatically and completely closed. Therefore, it can reduce heat loss, reduce dust intrusion, increase air tightness, and save energy. And cooperate with the negative pressure air conditioner of the operating room to reach the airtight standard of the operating room.
The closed door enhances the beautification function of the building. Because airtight doors are widely used in new designs, decorative materials and new processing techniques, their shape and structure will be more coordinated and matched with the building, enhancing the beautification function of the building. The working principle of the airtight door The inflatable airtight door is mainly composed of the door frame, the door panel, the inflatable sealing strip, the inflation and deflation control system, etc. The inflatable sealing strip is embedded in the groove of the door frame.
The four corners of the door frame and the door panel are curved corners of R < 150mm. The door panel is a sandwich structure, with heat and sound insulation materials in the middle, and the two side panels are firmly combined with a skeleton using laminated panel technology. The door frame and door panel are made of 304 or 316L stainless steel. The working principle of the inflatable airtight door is that when the door is opened, the inflatable sealing strip shrinks and contracts in the groove.
When the door is closed, the inflatable sealing strip is inflated to form a tight seal between the door and the door frame, and the door is tightly locked. The airtight door has good thermal insulation performance: the aluminum-plastic composite section has a low thermal conductivity of plastic, which is 1,250 times that of aluminum, and has good airtightness. In cold areas, although there are dozens of indoor and outdoor airtight doors, it is another world where the sound of airtight doors is good: its structural design, tight joints, test results, and sound insulation of more than 30dB, comply with relevant standards.
The influence of closed door: The outer surface of the aluminum alloy profile is made of aluminum-plastic composite material, and the impact force of the plastic steel window is greater than the resistance. The airtightness of the airtight door is good: the aluminum-plastic composite window is equipped with multiple belts or belt seals in each groove, airtight layering, fully exerting the air-conditioning effect, and energy saving by 50%. Watertight door and window design: waterproof structure, rainwater will be completely isolated from the outside world, and the water tightness conforms to national standards.
The airtight door has good fire resistance: the material is UPVC plastic steel doors and windows, which do not burn spontaneously and do not support combustion. The airtight door has good safety: the airtight door has good hardware accessories and advanced decorative locks, so thieves don't know what to do. Maintenance-free: The aluminum-plastic composite profile is not easy to be corroded by acid, does not turn yellow, and hardly needs maintenance. Clean and wash with dirt, water and detergent.
