In the design of cleanrooms for the semiconductor and electronics industry, corner treatment is a seemingly simple yet critically important detail. Today, I will provide a detailed analysis of a common corner detail design for clean areas, which adopts a combined structure of aluminum alloy and color steel plates, balancing aesthetics, durability, and cleanliness requirements.
Key Components of the Corner Detail Schematic
1. Aluminum Alloy Outer Corner R50
Function: Serves as the external protective layer and decorative surface of the corner.
Specifications: Designed with a 50mm radius arc (R50).
Advantages:
Arc design prevents dust accumulation and facilitates cleaning.
Aluminum alloy material is corrosion-resistant and oxidation-resistant.
Smooth surface does not generate dust, meeting cleanliness requirements.
Arc transition reduces airflow vortices, maintaining laminar flow.
2. 50mm Thick Color Steel Plate
Core Structure: Acts as the main wall material.
Characteristics:
50mm thickness provides sufficient structural strength.
Sandwich panel structure offers excellent thermal insulation.
Surface coating is anti-static and corrosion-resistant.
Complies with cleanroom requirements for non-dust-generating and non-dust-accumulating surfaces.
3. Rivet Fixation
Connection Method: Secures the aluminum alloy corner to the color steel plate.
Advantages:
Quick and easy installation, suitable for rapid cleanroom construction.
Firm and reliable connection with no risk of loosening.
No welding required, avoiding the generation of contaminating particles.
Smooth surface with no protruding elements.
4. Aluminum Alloy Inner Arc R50
Internal Treatment: Symmetrical arc design matching the outer corner.
Functions:
Forms a complete arc transition with no dead corners.
Facilitates cleaning and disinfection, preventing microbial growth.
Maintains smooth internal airflow.
Enhances overall aesthetics and professionalism.
Design Key Points Analysis
Cleanliness Considerations:
Double-arc design completely eliminates 90-degree sharp corners, preventing dust accumulation.
All material surfaces are smooth and non-porous, meeting Class 100-10,000 cleanliness requirements.
Minimized seams reduce contamination risks.
Structural Stability:
50mm thick color steel plates provide sufficient wall strength.
Rivet spacing is typically controlled at 150-200mm to ensure firm connections.
Aluminum alloy edging enhances corner impact resistance.
Installation Process:
Install color steel plate walls first, leaving space for corners.
Customize aluminum alloy corner pieces after precise measurements.
