Next, I will explain the characteristics of air-tight doors.

　　The six components, process characteristics, and customization features of air-tight doors.

　　Air-tight doors are designed to prevent direct airflow between the isolated space and the outside air, creating a certain negative pressure in the isolated space. This means that the pressure in the isolated space is lower than the external pressure, causing the external air to press down on the door, keeping it firmly closed. The good sealing of the isolated space is often used in medical doors.

　　Air-tight doors are one of the essential hospital-specific doors for many medical institutions. Their function is well understood; operating rooms need to perform surgeries without causing any impact on the doctors and patients involved. Therefore, air-tight doors are necessary. This will introduce the six components, process characteristics, and customization features of air-tight doors.

　　I. Six Major Components

　　1. Door Body

　　The door body of medical air-tight doors is mostly made of colored steel plates with polyurethane added in the middle. The thickness of the door panel is about 5cm, and the single-sided colored steel plate is about 0.374mm. You can also choose single or double doors based on actual needs, and the color can be decided according to requirements. Just paint the surface, and a well-painted door panel looks beautiful.

　　2. Observation Window

　　Although you may not be very familiar with the observation window of air-tight doors, it is what we call the observation window. Generally, the outer ring of the double-layer hollow tempered glass is made of aluminum alloy.

　　3. Anti-collision Belt

　　The anti-collision belt of medical air-tight doors serves two purposes: one is aesthetics, and the other is to prevent collisions.

　　4. Sealing Tape

　　Sealing tape is used around the door body for sealing, closely adhering to the wall to prevent gas leakage.

　　5. Door Opening Method

　　There are many ways to open medical air-tight doors; everyone can choose according to their needs, whatever is convenient.

　　6. Sliding Rail

　　The sliding rail of medical doors is used to move and fix the door body, and it also has the function of hiding the motor.

　　II. Technical Characteristics of Air-tight Doors

　　1. External Structure: The door body of the operating room air-tight door is equipped with high-quality vacuum sealing strips and is processed using efficient extrusion technology to ensure the air-tight effect of the door.

　　2. Internal Structure: The internal structure of the air-tight door uses a hard polyurethane overall high-pressure foaming process, combined with a high-strength aluminum frame, and is formed by stamping on a large platform with automatic lifting hydraulic equipment to ensure good flatness of the door.

　　III. Characteristics of Customization for Air-tight Doors

　　1. The surface of the air-tight door can choose materials based on user needs.

　　2. The air-tight door can be equipped with foot control switches and professional handles according to user needs for easy access.

　　3. Air-tight doors can also choose safety sensors based on user needs to prevent accidents.

　　The above points are the six components, technical characteristics, and customization features of air-tight doors introduced by the editor. You can refer to these when purchasing and choose according to your preferences. Of course, quality is more important.
