Comprehensive Analysis of Class 100 Cleanroom Partition Wall System Design and Construction

I. Core Structure Analysis of Partition Wall System

1.1 Main Frame System

Utilizes double-layer 50-series aluminum alloy framework to form composite load-bearing structure:

Main Columns: 80×40×2mm anodized aluminum profiles with vertical tolerance ≤0.1mm/m

Horizontal Supports: 50×30×1.5mm thermal break profiles with spacing ≤600mm

Seismic Joints: Stainless steel flexible connectors allowing ±5mm displacement

1.2 Panel System

Panel Type	Specifications	Special Treatment
Metal Surface	1.2mm SUS304 mirror panel	Electro-polished Ra≤0.4μm
Core Layer	50mm thick rock wool core	Hydrophobic rate ≥98%
Back Panel	0.8mm pre-coated aluminum	Antibacterial coating

II. Key Technical Points
