Cleanroom Enclosure Structure in Biopharmaceutical Cleanroom Engineering

Design and Construction Key Points of Cleanroom Enclosure

1. Uniform Layout of CNC Corridor

The layout design of CNC corridors must strictly adhere to cleanroom engineering standards, ensuring all components are arranged uniformly. Seams between walls, ceilings, and floors should be seamless to prevent dust accumulation. Materials should be corrosion-resistant and easy to clean, such as stainless steel or specially coated panels. The layout must account for equipment pipeline routing, reserve access panels, and maintain visual neatness.

2. Installation of CNC Corridor

During CNC corridor installation, the flatness and verticality of the base structure must meet requirements. The installation sequence should follow the principle of working from the inside out and top to bottom. All connection points must be sealed with specialized sealant to ensure airtightness. After installation, cleanliness testing must be conducted to verify compliance with the required ISO classification standards.

3. Installation of Floor-to-Ceiling Windows

Floor-to-ceiling windows in clean areas should use double or triple-pane tempered glass filled with inert gas for improved insulation and soundproofing. Window frames should be made of aluminum alloy or stainless steel with anodized surfaces. Special attention must be paid to sealing the joints between window frames and walls using structural silicone sealant to ensure airtightness. Glass surfaces should be coated with anti-static film to prevent dust adhesion.

4. Installation of External Windows

External windows must meet basic airtight and waterproof requirements while also addressing the special needs of clean areas. Window sashes should be fixed or non-operable to minimize external contamination. Laminated safety glass with UV-filtering interlayers is recommended. Continuous waterproof and vapor barriers must be installed at the junctions between window frames and walls, along with thermal insulation to prevent thermal bridging.
