Clean Room Door Manufacturer

Why are stainless steel cleanroom doors more popular in high-grade cleanroom doors?

Stainless steel cleanroom doors are increasingly favored in high-level cleanrooms, primarily due to their unique advantageous characteristics. These features make stainless steel cleanroom doors exceptionally effective in maintaining the high level of cleanliness required in such environments. The following are key reasons for the popularity of stainless steel cleanroom doors:

Exceptional Corrosion Resistance
Stainless steel cleanroom doors are made from stainless steel material, which has excellent corrosion resistance. It can withstand the effects of weak corrosive media such as air, steam, and water, as well as resist the chemical erosion of acid, alkali, and salt. This ensures that stainless steel cleanroom doors can maintain stable performance in various complex environments, ensuring that the cleanliness of the cleanroom remains unaffected.

Excellent Airtightness
The door panels of stainless steel cleanroom doors are firm and reliable. The seams around the door are tightly sealed with silicone, and an automatic lifting sweeper can be installed at the bottom of the door to reduce friction with the floor. These designs provide stainless steel cleanroom doors with excellent airtightness, effectively preventing dust, bacteria, and other contaminants from entering the cleanroom, thereby ensuring the cleanliness of the indoor space.

High Impact Resistance and Durability
The door leaves of stainless steel cleanroom doors are usually filled with paper honeycomb or aluminum honeycomb structures, which give the door panels high strength and hardness. This structure not only enhances the impact resistance of the doors but also prevents the door panels from deforming, denting, or peeling off. Therefore, stainless steel cleanroom doors can withstand frequent use and cleaning, maintaining long-term stability and durability.

Fireproof, Moisture-Resistant, and Easy to Clean
Stainless steel cleanroom doors have strong moisture resistance and certain fireproof properties. Their surfaces are smooth and flat, which does not accumulate dust and are easy to clean. For pollutants that are difficult to clean, special cleaning agents can be used for direct cleaning. They are easy to disinfect and clean, meeting sanitary cleanliness requirements.

Resistant to Erosion and Deformation
Compared to traditional doors, which are prone to deformation due to climate changes, frequent opening and closing, and impacts, stainless steel cleanroom doors are highly wear-resistant and have high resistance to acid and alkali corrosion. They have high strength and are not easily deformed. This ensures the stability and longevity of the cleanroom doors.

Environmentally Friendly and Healthy Raw Materials
The raw materials for stainless steel cleanroom doors are environmentally friendly and healthy, both during installation and use. They are also relatively economical and affordable. This makes stainless steel cleanroom doors not only meet the high standards required for high-level cleanrooms but also align with modern environmental protection concepts.

Due to their excellent corrosion resistance, airtightness, high impact resistance and durability, fireproof and moisture-resistant properties, ease of cleaning, resistance to erosion and deformation, and environmentally friendly and healthy raw materials, stainless steel cleanroom doors are more popular in high-level cleanrooms. These characteristics make stainless steel cleanroom doors an important choice for maintaining the high cleanliness of cleanroom environments.

How to keep the door frame and wall of the clean room door in the same plane?

Maintaining the door frame of a cleanroom door flush with the wall is crucial for ensuring the airtightness and aesthetics of the cleanroom. Here are several key steps and considerations on how to keep the door frame of a cleanroom door aligned with the wall:

Preparation Before Installation
Before installing the cleanroom door, ensure that the wall surface is smooth, free of debris, and without protrusions. Check the dimensions and shape of the door frame to make sure it matches the size of the door opening.

Door Frame Installation
Place the door frame inside the door opening and use a level and a vertical gauge to adjust the frame, ensuring it is level and perpendicular to the wall. The vertical error of the door frame's side posts with the ground should not exceed 2mm to ensure accurate installation dimensions. Use appropriate tools, such as a laser level, to check the perpendicularity of the front and side faces of the door frame and the horizontal level of the crossbar, ensuring the error is within the acceptable range (e.g., front and side perpendicularity not exceeding 2.5mm, horizontal level not exceeding 2.0mm).

Fixing and Sealing
Before fixing the door frame, double-check its position to ensure accuracy. For brick-concrete walls, use anchor bolts for fixing; for steel structures, light steel keels, or color steel plate walls, use self-tapping screws for fastening. The gap between the door frame and the wall should be even and must not exceed the specified range (e.g., not exceeding 1mm). Fill the gap with sealing material and seal it with sealant to ensure airtightness.

Adjustment and Verification
After installation, recheck the flatness of the door frame and the wall to ensure they are flush with each other. If necessary, make slight adjustments. Also, check the opening and closing of the door to ensure that the gap between the door leaf and the door frame meets the specified requirements (e.g., gaps on both sides not exceeding 3mm, top gap not exceeding 4mm, bottom gap between 8-10mm), ensuring the door's airtightness and usability.

Cleaning and Maintenance
During and after installation, keep the door frame and the wall clean, avoiding dust and debris that could affect airtightness. Regularly clean and maintain the door frame and the wall, check the condition of the seals and other easily damaged parts, and promptly replace any damaged components.

By following these steps and precautions, you can ensure that the door frame of the cleanroom door remains flush with the wall, thereby enhancing the cleanroom's airtightness and aesthetics. This also helps maintain the cleanliness and stability of the cleanroom environment.
