Cleanroom wall panels are often equipped with gaskets and seals at joints and connections to create an airtight barrier. This airtight seal is a crucial aspect of cleanroom design and construction, as it helps to maintain the controlled environment inside the cleanroom by preventing air leakage and minimizing the risk of particle and contaminant infiltration.
Gasket Materials: Gaskets are typically made from materials that offer excellent compression and recovery properties. Common gasket materials include silicone, EPDM (ethylene propylene diene monomer), neoprene, and polyurethane. These materials provide a secure seal while accommodating some movement between the connected panels.
Sealing Mechanism: Cleanroom wall panels are designed with interlocking edges and tongue-and-groove joints. The gaskets are placed between these joints, and when the panels are tightly connected, the gaskets compress to form a tight seal. This seal prevents air from passing through the gaps between the panels.
Joints and Connections: Cleanroom wall panels are precisely fitted together to create flush joints and connections. This design minimizes gaps and crevices where particles and contaminants could accumulate. The gaskets help ensure that even with minute gaps between the panels, the airtight seal is maintained.
Door and Window Seals: In addition to wall panel joints, gaskets and seals are also used around cleanroom doors, windows, and other openings. These seals prevent air leakage and contamination from entering or exiting through these access points.
Positive Pressure Management: Cleanrooms are often designed with positive pressure relative to the surrounding areas. The airtight seals on the wall panels play a vital role in maintaining this positive pressure, as any air leaks could compromise the controlled environment.
Compliance with Cleanroom Standards: The use of gaskets and seals in cleanroom wall panels is essential for meeting industry standards and regulations related to air cleanliness, contamination control, and airtightness.
By incorporating gaskets and seals in the design of cleanroom wall panels, facility managers can ensure that the cleanroom maintains its intended cleanliness level and controlled environment. Regular inspections and maintenance of these seals are necessary to identify and address any wear or damage that could compromise the effectiveness of the airtight barrier.
