Production Process------------------------------------------------------------------------------------
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
Successful Project---------------------------------------------------------------------------------------
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
