Laminated steel plate is a composite material with a special functional film on the surface of a metal substrate (such as galvanized steel plate, aluminum plate, etc.), combining the strength of metal with the corrosion resistance and easy cleaning characteristics of polymer materials. In cleanrooms (such as electronics, medicine, food, biological laboratories, etc., which have extremely high requirements for environmental cleanliness), laminated steel plates have become one of the mainstream decorative and structural materials due to their excellent performance. The following are its core applications and advantages:
I. Core applications of laminated steel plates in cleanrooms
1. Wall and partition system
– Clean sealing: The joints of laminated steel plates can be treated by seamless splicing process to avoid dust accumulation and bacterial breeding, which meets the strict requirements of cleanrooms for air tightness.
– Impact resistance: The metal substrate provides high-strength support, which is suitable for environments with frequent cleaning or equipment collision.
2. Ceiling system
– Lightweight design: It is lighter than traditional materials, reduces building loads, and has fireproof performance (such as Class A fireproof film).
– Concealed air duct: It can be integrated with the air supply and exhaust system to maintain uniform airflow organization in the workshop.
3. Door and transfer window
– Wear resistance: The surface is not easy to be scratched under high-frequency switching scenes, and it maintains its beauty.
– Transparent window integration: Some coated steel plates can be composited with transparent acrylic layers to facilitate observation of the interior of the workshop.
2. Matching the advantages of coated steel plates with purification needs
1. Cleanliness guarantee
– Self-cleaning: The surface is smooth (gloss can reach more than 80%), it is not easy to adhere to particles, and it can be quickly cleaned by wet wiping.
– Antibacterial: Optional silver ion coating or antibacterial film inhibits the growth of microorganisms and complies with GMP, ISO 14644 and other standards.
2. Environmental adaptability
– Stable temperature and humidity: It is not easy to deform in a constant temperature and humidity workshop, and the bonding strength between the film layer and the substrate is high (peel strength ≥ 5N/cm).
3. Convenient construction and maintenance
– Modular installation: Prefabricated panels are combined with the keel system to shorten the construction period and reduce on-site dust pollution.
– Repairability: Partial damage can be quickly replaced, reducing maintenance costs.
Through material innovation and process optimization, coated steel plates have achieved a balance between functionality and economy in cleanrooms, becoming the preferred solution for high-cleanliness environment construction. In practical applications, comprehensive selection should be made based on workshop levels (such as ISO Class 5 to 8), industry specifications and budget.
