Clean Room Wall

Characteristics of clean room walls

• Sealing performance

Sealing is a key characteristic of clean room walls. In the cleanroom, a space with extremely high environmental requirements, good sealing is like an indestructible defense line that can effectively block the invasion of external dust, microorganisms, and other pollutants, providing reliable protection for the indoor clean environment.

Once the sealing of the wall is poor, it will seriously affect product quality and the stability of the production process. For example, in the electronic chip manufacturing workshop, even extremely small dust particles entering may cause chip short circuits or other performance problems, significantly reducing product yield.

 In the bio-pharmaceutical laboratory, microbial contamination may interfere with experimental results, even leading to experimental failure and delaying the scientific research process.

When sandwich panels are installed on clean room walls, the joints between panels are usually sealed with professional sealant or sealing tape, further enhancing the sealing performance of the wall.

This sealing method not only effectively prevents the entry of external pollutants, but also prevents indoor air leakage, helping to maintain stable air pressure and airflow organization in the clean room, ensuring that all environmental parameters of the clean room are always in an ideal state. ​

• Corrosion resistance

In many special cleanroom environments, walls face challenges from various corrosive substances, making corrosion resistance an indispensable and important characteristic of cleanroom walls.

For example, in chemical production cleanrooms, strong corrosive chemical reagents such as acids and bases are often encountered. In food processing cleanrooms, cleaning agents, disinfectants, and acidic components in food may also cause corrosion to the walls.

If the clean room wall material does not have good corrosion resistance, it will suffer from surface peeling, rusting, damage and other problems after long-term corrosion, which not only affects the appearance and service life of the wall, but also leads to a decrease in the sealing of the clean room.

Pollutants are easily attached to the damaged wall surface, thereby polluting the indoor environment and posing a serious threat to product quality and personnel health.

• Dust-proof and antibacterial

The control requirements for dust and bacteria in clean rooms are extremely high, so the dust-proof and antibacterial properties of clean room walls are crucial. Once dust particles and bacteria accumulate and breed in a clean room, they may spread throughout the space with air flow, causing pollution to products and affecting their quality and performance.

For example, in the clean room of precision optical instrument manufacturing, dust particles may adhere to the surface of optical lenses, affecting the optical performance and imaging quality of the lenses. In medical and pharmaceutical cleanrooms, the presence of bacteria may lead to drug contamination, endangering the life and health of patients. ​

Clean room walls are usually made of materials with smooth surfaces, such as color steel sandwich panels, stainless steel sandwich panels, etc. These materials have high surface flatness and no obvious gaps or unevenness, making it difficult for dust particles to adhere to them.

Even if a small amount of dust falls on the surface of the wall, it can be easily removed through cleaning work. At the same time, some cleanroom wall materials also add antibacterial ingredients, such as adding silver ion antibacterial agents to the coating of color steel plates.

This dust-proof and antibacterial property effectively reduces the amount of dust and bacteria in clean rooms, providing a clean and hygienic environment for product production and research and development. ​

• Anti static electricity

In clean rooms, especially in industries such as electronics and semiconductors, the hazards of static electricity should not be underestimated. The generation of static electricity mainly comes from the separation of charges on the surface of objects, such as personnel walking in clean rooms, equipment operation, material handling, etc., which may lead to the accumulation of static electricity.

When static electricity accumulates to a certain degree, static discharge occurs, producing instantaneous high voltage and strong current. This type of electrostatic discharge may cause serious damage to electronic components, resulting in a decrease in their performance or even direct scrapping.

For example, in the process of chip manufacturing, small electrostatic discharges may break through the internal circuits of the chip, causing the chip to malfunction, reducing product yield, and increasing production costs.

In addition, static electricity can also adsorb dust particles, increasing the concentration of dust in the clean room and further affecting product quality. In some flammable and explosive clean room environments, electrostatic discharge may even cause fire or explosion accidents, endangering personnel life and property safety. ​

In order to cope with the harm caused by static electricity, some clean room wall materials will add conductive materials such as carbon fiber, metal fiber, etc. to achieve the dissipation of static electricity.

When static electricity is generated on the surface of the wall, the charge can quickly be conducted to the ground through the conductive network, thus avoiding the accumulation of static electricity.

For example, in some electronic workshops, an appropriate amount of carbon fiber is added to the anti-static color steel plate, making the color steel plate have good conductivity.

At the same time, during the installation process, the anti-static wall will be reliably connected to the grounding system to ensure that static electricity can be smoothly introduced into the ground, providing a safe and stable environment for the production and processing of electronic components.

The building materials for clean rooms wall are measured in terms of smoothness, flatness, cleaning resistance, and difficulty in breeding bacteria. The selection of clean room wall materials is a complex and critical task that requires comprehensive consideration of multiple factors.

Color steel sandwich panels have become a commonly used wall material in clean rooms due to their advantages of lightweight, high strength, easy installation, and diverse types.
