• Material Selection

  The frame of a clean room is usually constructed using industrial aluminum profiles or stainless steel squares as the main building materials, both of which have good strength and stability, and are able to withstand certain loads and maintain structural integrity. Among them, aluminum profile with its lightweight, strong, non-rust and non-dust characteristics, become the preferred material for clean shed frame. Common aluminum profile sizes include 4040 profile, 4080 profile, and other larger sizes such as 8080 profile, 6060 profile, 9090 profile, and 100100 profile to accommodate cleanroom construction of different sizes and load-bearing requirements.

• Structural design

  The structural design of the cleanroom emphasizes modularity and ease of assembly. This design allows the shed to be erected and dismantled in a short period of time, making it easy to reuse for different occasions and times. In addition, the top of the clean room is usually equipped with a Fan Filter Unit (FFU), which is the key equipment to maintain the cleanliness of the room; the FFU is responsible for providing continuous fresh air input and filtration to ensure that the cleanliness of the air in the room meets the predetermined standards.

• Auxiliary Materials

  In addition to the main framing and structural components, the clean room will also use a variety of auxiliary materials, such as anti-static mesh curtains, anti-static aluminum composite panels, and 0.5mm mesh anti-static vinyl for the enclosure. These materials are chosen to minimize dust build-up and static interference, providing a cleaner and more controlled production environment.

• Structural components

  The main components of a clean room include a sturdy metal frame (usually made of industrial aluminum, stainless steel or painted iron), anti-static curtains or tempered glass enclosure, a fan-filter unit (FFU), and a high-efficiency filter. These components work together to form a clean environment with uniform airflow from the top, and internal purification levels ranging from Class 100 to Class 100,000, depending on the application.

• Application Areas

  The clean room is widely used in various industries where there are strict requirements for cleanliness in the work area. In the electronics manufacturing industry, it can protect sensitive components from dust contamination and improve product quality. In the pharmaceutical industry, the clean room ensures aseptic conditions during the production of medicines, guaranteeing the quality and safety of medicines. The food processing industry utilizes clean rooms to maintain food safety standards and prevent cross-contamination. In addition, laboratories and research institutes rely on clean rooms to provide a suitable research environment to improve the success and accuracy of experiments.

• Benefits

  The benefits of a clean room are its flexibility and convenience. It can be set up and put into use quickly and can be moved or reconfigured as needed. Another distinguishing feature of this structure is its modular design, which allows the Clean Shed to easily increase or decrease the number and size of FFUs to accommodate different cleanliness requirements. In addition, the Clean Shed is cost-effective, with lower investment and operating costs compared to traditional cleanroom construction, and has low floor height requirements, making it suitable for a wide range of site conditions.

Material Selection

When choosing materials for the clean shed, priority should be given to materials with good airtightness and small deformation, especially when the wall is internally decorated, if additional structural skeleton and heat preservation layer are needed, non-combustible or flame-retardant body materials should be used.

Structural Requirements

The surfaces of walls and ceilings of the clean room must be flat, smooth, dust-free, and effective in avoiding glare and easy to remove dust. The design should reduce the concave and convex surfaces and chamfer the corners of yin and Yang. The standard of finish shall be interior high-grade plaster.

Ground Requirements

The floor of the clean room should be smooth, wear-resistant, easy to dust and clean, and at the same time should not accumulate static electricity, and can effectively avoid glare.

Construction Steps

• Construction preparation: including site survey, development of construction program, preparation of materials and equipment, determine the construction team.

• Foundation construction: Ensure that the foundation construction is level, solid and horizontal, and carry out acceptance.

• Frame installation: use steel to make the frame and ensure its verticality and horizontality, and then carry out anti-corrosion and anti-rust treatment.

• Ceiling and wall plate installation: use purification board or other materials that meet the requirements to ensure the flatness and tightness of the seams of the ceiling and wall plate.

• Installation of air purification system: including high-efficiency filters, air shower rooms, ultraviolet disinfection lamps, etc. Ensure that the connection between each component is tight to avoid air leakage.

• Lighting system installation: choose waterproof and dustproof LED lamps to ensure the uniformity of lighting.

• Electrical system installation: comply with relevant national standards and industry requirements to ensure stable and safe power supply.

• Grounding treatment: grounding treatment according to the design requirements to ensure the safe operation of the equipment.

• Acceptance and debugging: carry out acceptance after the installation is completed to ensure the normal operation of the systems and achieve the expected clean effect.

• Air Cleanliness Testing

  Air cleanliness is one of the core items in the environmental testing of the clean room. The cleanliness level of the shed is assessed by collecting air samples from the shed and using professional particle counters to count and size the airborne particles. Usually, the cleanliness level of a clean room is classified by the number of particles per unit volume, such as the class classification in ISO 14644-1 standard.

• Microbiological Testing

  Microbiological contamination is an important issue in the clean room environment. Microbiological testing involves sampling the air, surfaces, and people in the shed, and then detecting the types and numbers of bacteria, molds, and other microorganisms present in it through culture, microscopic observation, and other methods. This information helps to understand the status of microbial contamination in the shed and take appropriate measures to control it.

• Temperature and Humidity Detection

  Temperature and humidity are important factors that affect the stability of the clean shed environment. The temperature and humidity in the shed are monitored and recorded in real time through instruments such as thermohygrographs to ensure that they meet production requirements. Generally speaking, the temperature and humidity control range of the clean room is more strict to meet the requirements of the production process and equipment.

• Differential Pressure Inspection

  Differential pressure testing is an important means of evaluating the air flow between different areas in a clean room. Instruments such as differential pressure meters are used to measure the pressure difference between different areas in the clean room to understand the direction and speed of air flow. This is important to ensure that the direction and distribution of air in the clean room meets the design requirements.

• Surface Cleanliness Inspection

  Surface cleanliness refers to the cleanliness of various surfaces (such as walls, floors, equipment shells, etc.) in the shed. Through the visual inspection of these surfaces, wipe test and other methods to assess the level of cleanliness. Whether the surface cleanliness is qualified or not directly affects the quality of the product and the stability of the production environment.

• Vibration and Noise Detection

  Vibration and noise are common disturbing factors in the clean room environment. Through vibration and noise testing of equipment, piping, etc. in the shed, the impact on the clean environment and product quality is assessed. If the vibration and noise exceeds a certain range, it may adversely affect the cleanliness and stability of the clean room, and timely measures need to be taken to improve the situation.

• Lighting Inspection

  Lighting is an important factor that affects the comfort of the working environment in the clean room. By testing the lighting facilities in the shed, we assess whether its illumination, uniformity, color temperature and other indicators meet the requirements. Reasonable lighting design not only helps to improve employee efficiency, but also ensures product quality and production stability.
