Cleanroom sandwich panels - Specialized solutions for high hygiene standard environments
Cleanroom sandwich panels are composite panels specially designed for high-cleanliness demand scenarios such as medical care, electronics, and food. They are composed of a surface layer (galvanized steel plate /PVC film), core material (rock wool/aluminum honeycomb), and an antibacterial coating. They comply with the ISO 14644-1 cleanliness standard and provide an integrated solution featuring seamless surfaces, fire safety, and quick installation.
Class A fire resistance: The rock wool core material meets the GB 8624 A1 non-combustible standard, eliminating fire hazards.
Antibacterial and antifungal: The surface has passed the ISO 22196 antibacterial test, with an antibacterial rate of ≥99.9%.
Anti-static design: Optional ESD coating (surface resistance 10^6 to 10^9Ω), protecting precision instruments.
Chemical resistance: Resistant to acid and alkali cleaners with pH ranging from 3 to 11, suitable for laboratories and pharmaceutical factories.
Quick installation: Modular assembly structure shortens the construction period by 30%, and supports on-site cutting.
Environmental protection certification: E1 environmental protection standard, passed SGS heavy metal-free test.

1. Raw Material Selection:
* Basalt rock (SiO₂≥45%, Al₂O₃≥14%) + slag (≥70% recycled)
2. Fiber Production:
* Electric furnace melting (1,500-1,600°C) → Four-roller centrifugal spinning (7,200rpm) → Fiber diameter 4-7μm
3. Curing Process:
* Phenolic resin spraying (formaldehyde emission ≤0.05ppm, EN 717-1) → Curing oven at 230°C
4. Lamination:
* Steel plate pretreatment (degreasing → phosphating → nano-ceramic coating) → Continuous hot pressing (1.2MPa, 180°C)
5. Quality Control:
* Online X-ray inspection (void detection) → Laser thickness gauge (±0.1mm accuracy) → Batch fire performance testing
Semiconductor Wafer Fabs (Class 10 Cleanrooms)
* Solution:
* Wall-ceiling system integrated with HEPA filters
* Grounding resistance <1×10^6Ω, compliant with SEMI F47 voltage sag standards
* Case Study: 32,000㎡ deployed in a Taiwan 12-inch wafer fab project
Facilities
* Key Technologies:
* Radius corners (R≥50mm) to eliminate cleaning dead zones
* Pre-installed ports for real-time particle monitoring
Data Center Retrofits
* Energy Efficiency Data:
* U-value 0.28 W/m²·K → 18% annual cooling energy savings
