What Materials Are Hidden Behind High-Performance Clean Room Partition?

With the rapid development of high-precision industries such as pharmaceuticals, electronics, semiconductors, and food processing, the importance of clean rooms in ensuring product quality and production safety has become increasingly prominent. In clean room systems, a Clean Room Partition is not merely a tool for dividing space—it also plays a critical role in controlling airflow, managing cleanliness, and ensuring operational safety. So, what key materials lie behind high-performance partitions, and how do their properties affect clean room operations?

Material Insights

The choice of materials for partitions directly determines their durability, sealing performance, cleaning efficiency, and ability to protect the controlled environment. High-performance partitions not only fulfill the basic function of space division but also need to balance airflow management, contamination prevention, impact resistance, and long-term durability. The following is a detailed analysis of commonly used materials for high-performance clean room partitions:

1. Stainless Steel

Physical Properties: Stainless steel offers corrosion resistance and mechanical strength. Grades 304 and 316 are commonly used, with surfaces brushed, polished, or sandblasted to ensure smoothness and flatness.

Durability: Long-term use without rust or deformation; withstands frequent cleaning and disinfection, providing a long service life.

Cleanability: Smooth surfaces facilitate wiping and disinfection, minimizing microbial harboring.

Workability: Can be custom-cut, bent, and welded according to clean room dimensions; suitable for door frames, window frames, and other structural components.

Cost Analysis: Initial investment is slightly higher, but low maintenance costs make it advantageous over the long term.

Application Example: In pharmaceutical production areas, high-grade clean zones use stainless steel doors and windows, maintaining stable particle counts and reducing cleaning frequency.

2. Aluminum Alloy

Physical Properties: Lightweight yet strong, commonly 6063-T5 or 6061 alloys, with anodized or coated surfaces to improve corrosion resistance and appearance.

Durability: Resistant to wear, maintaining integrity despite frequent use or door operation.

Cleanability: Smooth surfaces withstand routine cleaning agents and disinfectants.

Workability: Easily cut, welded, and surface-treated; supports complex shapes, modular designs, and movable partition solutions.

Cost Analysis: Moderate cost; lightweight nature reduces transportation and installation expenses.

Application Example: Modular aluminum alloy partitions in electronics workshops allow rapid assembly and layout adjustment, supporting flexible production lines.

3. Glass / Acrylic (Tempered or Acrylic Glass)

Physical Properties: Transparent materials; tempered glass is heat-resistant and impact-resistant, while acrylic sheets are lightweight and easily cut.

Durability: Tempered glass resists breakage; acrylic is impact-resistant but prone to scratching.

Cleanability: Smooth and transparent surfaces can be repeatedly wiped, ideal for observation windows.

Workability: Can be cut, drilled, sandblasted, or laminated; suitable for observation windows, operation ports, or internal partitions.

Cost Analysis: Moderate cost; double-layer laminated glass is slightly higher in price but offers enhanced safety and sound insulation.

Application Example: Double-layer observation windows in electronics assembly areas allow operators to monitor equipment without frequent door openings, reducing airflow disturbance and contamination risk.

4. Composite Panels

Physical Properties: Usually constructed with a metal frame combined with anti-static boards, high-density polymer panels, or other functional sheets, achieving a combination of lightweight structure, rigidity, and multifunctionality.

Durability: Stable structure, corrosion- and wear-resistant, able to withstand frequent operations and material handling.

Cleanability: Smooth surfaces suitable for frequent wiping and disinfection.

Workability: Can be customized in size, thickness, opening type, and additional features (e.g., anti-static, fire-resistant, chemical-resistant).

Cost Analysis: Initial investment is moderate to high, but multifunctionality and long maintenance intervals provide cost-performance ratio.

Application Example: Semiconductor clean zones use composite partition panels to achieve anti-static and chemical-resistant functionality while supporting high-frequency access and modular layouts.

• Effect: Surfaces remain flat and uncontaminated over time, extending partition lifespan.
• Example: In pharmaceutical clean zones, daily disinfection of partitions shows no rust or deformation, significantly reducing maintenance workload.

4. Sound Insulation and Temperature Control

• Principle: Multi-layer composite materials, laminated glass, or hollow panels provide acoustic and thermal isolation.
• Effect: Effectively reduces environmental noise interference and maintains stable indoor temperatures, supporting equipment operation and personnel comfort.
• Example: In an electronics clean room, noise from nearby large equipment was mitigated by soundproof composite partitions, lowering noise levels to safe limits and reducing air-conditioning load.

5. Automation and Interlocking Control

• Principle: Some partition doors feature electric drive systems that can interlock with air showers, air purification systems, or pass-through windows to enable automatic opening/closing and pressure adjustment.
• Effect: Minimizes contamination risks from manual operation, maintains clean room pressure balance, and improves access efficiency.
• Example: In high-grade electronics clean zones, automatic doors interlocked with air showers adjust airflow with every opening and closing, ensuring stable cleanliness levels.

Installation and Maintenance

The performance of high-performance partitions largely depends on the quality of installation and daily maintenance. Proper installation and scientific maintenance not only ensure the partitions' airtightness, dust-proofing, and durability, but also extend equipment lifespan, reduce operational costs, and maintain long-term clean room stability.

1. Installation Considerations

a. Precise Dimensional Measurement

Before installation, accurately measure the actual dimensions of the clean room, including wall flatness, floor level, door orientation, and passage width.

Dimensional deviations may result in poor door/window sealing or difficult operation, affecting airflow and cleanliness.

b. Sealing Treatment

The joints between partitions and walls, floors, and ceilings should use high-quality sealing strips, insets, or welded fixings to prevent air leakage.

For high-grade clean rooms, a double-seal design can be implemented to maintain stable positive/negative pressure.

c. Matching Airflow Systems

Installation locations should align with the clean room's airflow design to avoid short-circuits or dead zones.

For modular partitions, airtightness between units must be ensured to prevent local cleanliness degradation.

d. Support and Fixing Structures

Use sturdy support frames or hangers to ensure verticality and stability.

For tall partitions or large transparent windows, additional reinforcement is required to prevent deformation or shaking.

2. Maintenance Requirements

a. Regular Cleaning

Surfaces and sealing strips should be cleaned periodically to prevent dust, particle, and microbial accumulation.

Use neutral cleaners or disinfectants suitable for the materials; avoid solvents that can corrode metals or coatings.

b. Mechanical Component Inspection

Automatic or sliding doors require periodic inspection of rollers, tracks, controllers, and locks to ensure smooth operation and proper sealing.

For electrically driven partitions, establish routine inspection schedules to avoid control system failures affecting access.

c. Scratch and Damage Protection

Apply scratch protection to glass or acrylic observation windows; replace panels promptly if scratched or damaged.

For composite panel partitions, prevent collisions with heavy objects to maintain surface integrity and sealing performance.

d. Replacement of Seals and Accessories

Replace worn or aged sealing strips, elastic components, and other critical parts based on usage frequency and environmental conditions.

Maintain seals soft and intact to ensure long-term airtightness.

Case Study: In an electronics clean room, regular maintenance and inspection ensured smooth partition system operation over extended periods, with no sealing damage, reducing maintenance costs.

Tip: Accurate installation and scientific maintenance are prerequisites for the long-term stable operation of high-performance partitions.
