Hermetic doors are playing an increasingly crucial role in modern industries. From the operating rooms of hospitals, to the production workshops of electronic chips, and even to the clean areas of food processing, Hermetic doors have their excellent performance.Hermetic door is to ensure production safety, improve product quality, and maintain the medical environment. Here you will find the characteristics, materials, and wide range of applications of the hermetic doors.
Characteristics of hermetic doors
-
Excellent sealing performance
It installs specially designed silicone seals on each side of the door leaf and uses unique compression technology to ensure that the door can tightly fit with the door frame when closed, minimizing gaps as much as possible.
The sealing strip of the hermetic door will achieve seamless contact with the door frame and the ground, effectively preventing air leakage.

Excellent sound insulation
Hermetic doors bring excellent sound insulation effect. The door body usually adopts a multi-layer composite structure, filled with sound-absorbing materials such as rock wool, honeycomb paper, etc., which can effectively absorb and block the propagation of sound.
At the same time, the tight sealing strip not only blocks air, but also acts as a barrier to the propagation path of sound.

Good insulation performance
For places that require a constant temperature environment, such as laboratories, precision instrument storage rooms, etc., this can ensure the stability of indoor temperature, guarantee the accuracy of experimental data, and ensure the normal operation of instrument equipment.

Steel materials for hermetic doors
There are diverse types of materials for hermetic door. including stainless steel and galvanized sheet. 304 stainless-steel, has excellent corrosion resistance and can maintain the integrity of door panels for a long time in humid and chemically corroded environments, making them less prone to rusting.
Its surface is smooth and easy to clean, which is crucial for places with high hygiene requirements such as hospitals and food processing workshops, as it can effectively prevent the adhesion of bacteria and dirt.
At the same time, stainless steel material has high strength, making the door body sturdy and durable, and able to withstand certain impact forces. However, the cost of stainless-steel door is relatively high, it may increase the budget in some clean room projects with strict cost control.
Galvanized sheet is a layer of zinc coated on the surface of ordinary steel plate to improve its corrosion resistance. Its price is relatively affordable and it is widely used in environments where corrosion resistance requirements are not particularly extreme.
However, the corrosion resistance of galvanized sheet is slightly inferior to that of stainless steel. If it is exposed to harsh environments for a long time, the zinc layer may peel off and rust.
Sandwich material for hermetic door
Sandwich materials for hermetic doors play a crucial role, commonly including paper honeycomb, aluminum honeycomb, and rock wool. Paper honeycomb is lightweight and cost-effective, which can improve the sound insulation and thermal insulation performance to a certain extent.
Aluminum honeycomb stands out for its lightweight and high strength. It can effectively enhance the pressure resistance of the door, while also performing well in sound insulation and thermal insulation performance. Hermetic door with aluminum honeycomb sandwich has a good effect on heat transfer control.
Rock wool is a high-quality non flammability insulation material, which can effectively prevent the spread of fire. It is especially suitable for places with strict requirements for fire prevention.
Application of hermetic door

Medical field
Hermetic doors can be seen in operating room since its excellent sealing performance can effectively prevent bacteria, dust, and other substances from entering the outside air of the operating room, maintaining a sterile environment inside the operating room.
Meanwhile, its excellent sound insulation performance can also prevent external noise from interfering with the surgical process, allowing medical staff to focus on surgical operations in a quiet environment.
Radiology departments also rely on hermetic doors. X-ray, CT and other examination equipment generate ionizing radiation during operation. If this radiation leaks into the surrounding environment, it can pose a potential health threat to medical staff and other patients. The hermetic door can tightly seal the radiology examination room, prevent radiation leakage, and ensure personnel safety.

Food industry
Hermetic doors in the food industry provides strong guarantees for food safety. The food production workshop needs to maintain a high level of cleanliness to prevent pollutants from entering, so as not to affect the quality of the food.

Industrial plant
Hermetic door is also applied in industrial plant like chip manufacturing workshops or electronic workshop.
