Clean Room Wall Material
Bona is a clean room panel, door and window manufacturer in China supplying construction materials for clean room projects.
The cleanroom strictly controls key parameters such as particles, temperature, humidity, and pressure in the air to maintain a specific cleanliness level, providing reliable assurance for production and experimental processes that are highly sensitive to pollution.
For example, in the medical industry, the application of clean rooms in operating rooms can greatly reduce the risk of infection during the surgical process. Or in the electronics industry, cleanrooms that meet standards can control the defect rate within 5%. Chip manufacturing giants such as Intel and TSMC have invested huge amounts of money in cleanroom construction and maintenance.
As an important component of clean rooms, wall materials play a crucial role in maintaining the clean room environment. The clean room wall material not only need to have basic enclosure functions, but also need to meet a series of special requirements.
It must be able to effectively prevent dust generation, not easily accumulate dust, and be easy to clean and maintain in order to reduce dust particles in the workshop and maintain high indoor cleanliness.
In some pharmaceutical workshops, the walls are wiped clean every day. If the wall materials are difficult to clean, it will greatly increase maintenance costs and time. Good sealing is also an essential characteristic of clean room wall material.
On the one hand, it can prevent external pollutants from entering the clean room during disinfection, maintaining indoor cleanliness. On the other hand, it can prevent indoor pollutants from leaking into non clean areas, avoiding potential harm to the surrounding environment and personnel.
When conducting research on highly infectious viruses in some biological laboratories, well-sealed walls can ensure that the virus does not leak, ensuring the safety of laboratory personnel and surrounding populations.
Color steel sandwich panel: a popular choice for clean rooms
Color steel sandwich panels play an important role in the construction of clean rooms and are currently one of the most widely clean room wall materials. Mainly because it has the following advantages:
1. Lightweight and high-strength: The weight of color steel sandwich panels is relatively light, making it extremely convenient to transport and install, greatly reducing the difficulty and labor costs of construction.
2. Thermal insulation: The high-performance insulation material in the middle layer of the sandwich panel can significantly reduce the thermal conductivity.
3. Easy installation: The color steel sandwich panel has standardized dimensions and modular design, making the installation process simple and fast. A medium-sized clean room can shorten the construction time by 20% -30% compared to traditional wall materials if color steel sandwich panels are used to complete the wall materials.
4. Smooth and easy to clean surface: The surface of the sandwich panel is very smooth and not prone to dust accumulation, and it is very easy to clean. In the daily maintenance of the clean room, staff only need to gently wipe with a damp cloth to remove surface dust and stains, effectively reducing the impact of dust on the clean room environment and providing a clean space for product production and experimentation.
5. Variety: according to different core materials, sandwich panels can be divided into various types, such as polystyrene sandwich panels, polyurethane sandwich panels, rock wool sandwich panels, phenolic foam sandwich panels, etc.
Each type has its unique performance advantages, and users can choose according to the specific needs and budget of the clean room. If high requirements are placed on fire resistance, rock wool sandwich panels can be chosen. If more emphasis is placed on thermal insulation performance, polyurethane sandwich panels are a good choice.
However, sandwich panels also have some shortcomings, such as insufficient strength. In some special circumstances, such as when subjected to strong impacts or significant pressure, its strength may not meet the requirements.
Suggestions for selecting clean room wall materials
1. Selection based on the cleanroom level
Cleanrooms of different levels have completely different requirements for wall materials. In high-level clean rooms, such as ISO level 5 and above, used in semiconductor chip manufacturing, high-end biopharmaceuticals, and other fields, strict control of dust and microorganisms is required.
At this point, stainless steel sandwich panel have become the preferred choice due to their excellent antibacterial, dustproof, and corrosion-resistant properties. Its surface is smooth, not prone to dust accumulation, and can effectively inhibit bacterial growth, ensuring high cleanliness of indoor environment.
In cleanrooms with slightly lower levels, such as ISO 6-9, used for general precision manufacturing, food processing, and other industries, color steel sandwich panels are more favored due to their high cost-effectiveness and convenient installation. It can meet basic cleanliness requirements while reducing construction costs.
2. Consider environmental factors for use
Environmental factors have a significant impact on the selection of wall materials. In environments with high humidity, such as cleaning areas in food processing workshops and wet and hot sterilization areas in pharmaceutical workshops, the moisture resistance of materials is crucial.
Stainless steel plates are more suitable for materials with good moisture resistance, as they can effectively prevent material deformation, mold and other problems caused by moisture.
3. Balance cost and performance
Balancing cost and performance is a key when choosing cleanroom wall materials. Firstly, it is necessary to clarify the core requirements of the clean room. For industries that require extremely high cleanliness and high product added value, such as chip manufacturing, material performance should be given priority.
Even if the cost is high, the material that best meets the requirements, such as stainless-steel plate, should be selected to ensure product quality and production safety. For projects with relatively low cleanliness requirements and limited budgets, such as ordinary food processing workshops, low-cost materials such as polystyrene color steel sandwich panels can be selected while meeting basic cleanliness requirements.
