What Is The Difference between Clean Room Decoration And Ordinary Decoration?

In many people's cognition, decoration is nothing more than the routine processes of wall ceiling, floor laying, water and electricity wiring. But in fact, clean room decoration is completely different from ordinary home decoration and office decoration. Especially in pharmaceutical factories, electronics factories, medical laboratories, semiconductor workshops and other environments with extremely high requirements for air cleanliness, decoration is not only beautiful and practical, but also an important link that directly affects product quality and production safety. So, what is the difference between clean room decoration and ordinary decoration? Let's talk about this topic in detail today.

The requirements for spatial structure are completely different

Ordinary decoration usually focuses on the functionality and aesthetics of the space, such as partitions, ceilings, lighting design, etc., which are more for enhancing the visual experience or making rational use of space. The core of Clean Room Design decoration is to plan the spatial structure around airflow organization, pressure difference control, dust particle isolation and static electricity management.

For example, ordinary offices can open windows and install air conditioners at will, but in clean rooms, all windows must be closed, doors, windows and equipment openings must be tightly closed to prevent outdoor air from infiltrating. The Modular Clean Room structural design is more flexible. It adopts a modular assembly method, which can flexibly adjust the layout according to process requirements, and is easy to disassemble, expand or maintain. This Clean Room Construction method can effectively improve the efficiency of project construction and meet the production environment requirements of different companies.

The selection standards for decoration materials are more stringent

In ordinary decoration, the commonly used materials such as latex paint, wood veneer, gypsum board, ceramic tile, wall cloth, etc. are mainly considered for beauty and cost performance. However, the primary standard for the internal materials of the clean room is corrosion resistance, no dust, no dust accumulation, easy to clean, antibacterial and mildew-proof.

For example, walls and ceilings are mostly made of color steel sandwich panels, among which magnesium oxysulfide board, stainless steel board, and aluminum honeycomb board are common materials. The ground needs to be paved with special epoxy resin self-leveling floor or PVC coil to ensure seamless connection and avoid dirt. In addition, Clean Room Design has strict environmental protection and cleanliness requirements for glue, sealant, and caulking agent to prevent the release of volatile organic compounds (VOCs) to pollute indoor air.

The construction process is extremely standardized

In ordinary home improvement sites, flying dust and debris are the norm, while the dust-proof, anti-static and anti-pollution management system must be strictly implemented at the clean room decoration construction site.

Before entering the site, construction workers need to change into clean clothes, masks and gloves, and some areas even require dust-free shoes and hats.

There is a temporary air shower equipment at the construction site, and all materials and personnel must go through the dust removal procedure before entering the construction area.

During the Clean Room Construction process, any drilling, cutting, welding, grinding and other dust-generating processes must be equipped with special dust collection equipment, and must be cleaned immediately after construction to ensure that the air cleanliness on site does not exceed the standard.

The entry of materials, equipment installation, and system debugging must be strictly carried out in accordance with the construction organization plan, and the whole process must be recorded for future clean verification.

The system is complex and involves multi-professional collaboration

General decoration mainly involves conventional work such as water and electricity, carpentry, masonry, and painting, but the clean room is a typical multi-professional collaborative construction project, involving:

• Air purification system (HVAC)

• Electrical lighting system

• Clean air conditioning system

• Automatic control system

• Pressure difference control system

• Process piping system

• Clean Room Modular assembly

Each system must not only independently complete professional functions, but also work together to ensure the clean level and production safety of the entire clean room. For example, the air conditioning system must not only adjust the temperature and humidity, but also maintain positive pressure to prevent external pollutants from infiltrating. At the same time, the layout of the purification filter must also comply with the Clean Room Design standard to avoid airflow short circuit.

High requirements for cleanliness level and environmental testing

The completion acceptance of general decoration only needs to meet the standards of beauty, function, safety and environmental protection. After the clean room is decorated, it must be tested for cleanliness level, such as:

• Air suspended particle number detection

• Wind speed and volume detection

• Pressure difference detection

• Noise detection

• Temperature and humidity detection

• Fresh air volume detection

The cleanliness level is divided according to ISO 14644 standard, from Class 1 to Class 9, the lower the value, the higher the level. For example, the number of particles ≥ 0.5μm in the air of ISO Class 5 must be less than 3520/m³, while ordinary indoor air is generally as high as more than one million.

In addition, Modular Clean Room also needs to conduct performance tests on equipment such as air showers, transfer windows, self-cleaners, filters, etc. to ensure that all clean facilities function normally.

Standardization of maintenance management system

After ordinary decoration is completed, the owner can freely arrange and modify according to actual use, but after the clean room is officially put into operation, all operations, maintenance, inspections, cleaning, and disinfection have strict SOP processes.

For example:

Equipment maintenance must be disassembled outside the clean area, and on-site repairs are strictly prohibited.

Clean room cleaning must be performed regularly on a daily, weekly, and monthly basis. Some high-level Clean Room Designs also require dust-free wiping, ultraviolet disinfection, and surface sampling and testing.

All personnel, materials, and tools entering and leaving must be dusted through air showers and buffer rooms to prevent cross contamination.

Especially the Modular Clean Room system, which is convenient for later expansion or layout adjustment, but each change must also be re-tested for cleanliness and review the Clean Room Construction standards to ensure the stability of the entire dust-free environment system.

Summary

The biggest difference between clean room decoration and ordinary decoration is not the surface effect, but its ultimate pursuit of environmental cleanliness and system stability. It is not only a space design, but also a comprehensive engineering project involving air purification, pressure difference control, anti-static, microbial management, etc. The construction standards, material specifications, system matching and acceptance inspection system are extremely rigorous.

Therefore, if your company is involved in the pharmaceutical, medical device, semiconductor, electronics, food, cosmetics and other industries, whether it is a new project or a workshop renovation, it is recommended to give priority to professional Clean Room Design and Clean Room Construction service providers, especially manufacturers with experience in Modular Clean Room solutions, who can provide more efficient, economical and flexible clean room decoration solutions based on process requirements and project budgets.
