• Frame Material

  The frames of clean booths are usually made of industrial aluminum profiles, stainless steel squares or baked enamel squares, which have good stability, corrosion resistance and aesthetics. Aluminum profile with its lightweight, strong, easy to clean the characteristics of the clean shed framework has become the preferred material. Stainless steel squares, on the other hand, are used in certain wet environments due to their excellent corrosion resistance.

• Wall Material

  The choice of wall material is critical to the sealing and dust-proofing properties of the cleanroom. Common wall materials include anti-static drapes, acrylic panels and tempered glass. Anti-static curtains are widely used in clean rooms due to their good transparency and dustproof performance. Acrylic panels are used for their light transmission and chemical stability. Toughened glass is used where higher strength and transparency are required.

• Filtration System

  The filtration system inside the clean room is the core part, responsible for providing the necessary clean air. the FFU (Fan Filter unit) is the key component to realize this function, which not only provides the necessary fresh air volume, but also removes the pollutants in the air through the highly efficient filtration system.

• Clean room characteristics

  The design and application of the clean room reflects its importance in industrial production, especially in the precision machinery, electronics, aerospace, high-purity chemical, atomic energy, photoelectric products and other industries with a wide range of applications. It is characterized by its ability to quickly build, easy to move and modular combination, can be quickly adjusted according to the production needs of cleanliness level, but also has a lower cost and shorter construction period.

• Application Scenario

  Clean room is widely used in electronic manufacturing, medicine and health, food processing, precision instrument manufacturing and scientific research experiments and other fields. It can not only provide a highly clean working environment, but also effectively control costs and improve product quality and productivity.

Installation Steps

• Prepare installation tools: Make sure all necessary tools and materials are ready, including but not limited to metal frame, high efficiency filter (HEPA), FFU (Fan Filter Unit), etc.

• Build the metal frame: two people climb to the ceiling first, lay the assembled metal foot keel and hanging trusses, the other two people will place the FFU on the table, pre-prepared high-efficiency filters.

• Installation of FFU: After fixing the aluminum ladder, the fan unit is lifted to the ceiling and ensured to be level, followed by the person on the ceiling to catch the tilted FFU.

• Installation of HEPA filter: In the clean room, two persons hold the HEPA filter and hand it over to the staff for installation, and install it diagonally to the keel by the staff on the ceiling, pay attention to protect the HEPA filter to prevent damage.

• Installation and commissioning: After lifting the FFU, the staff in the clean room will install the filter diagonally to the keel, install the HEPA filter horizontally and combine it with the keel effectively. Put down the FFU, close to the high-efficiency filter to install the air unit, be careful not to damage the filter, and check whether the FFU is pressed tightly.

• Inspection and acceptance: Check after the installation is completed to ensure that all components are correctly installed and function properly, and finally confirm that there are no errors marking the completion of the installation.

Precautions

• The installation location should be dry, ventilated, well-lit, avoid direct sunlight, and meet special requirements such as anti-static and anti-corrosion.

• The foundation construction should be in accordance with the design requirements to ensure that the foundation is level, solid and horizontal, and acceptance is carried out.

• The frame installation should be made of steel profiles to ensure the verticality and levelness of the frame, and complete the anti-corrosion and anti-rust treatment.

• The roof and wall panel installation should use purification board or other materials that meet the clean requirements to ensure flatness and tight seams.

• Air purification system installation includes high-efficiency filters, air shower rooms, ultraviolet disinfection lamps, etc. to ensure tight connections and avoid air leakage.

• Lighting system installation should ensure the waterproof and dustproof performance of lamps and lanterns and the uniformity of illumination.

• The installation of electrical system should comply with national standards and industry requirements to ensure stable and safe power supply and normal operation of equipment.

• Grounding treatment should meet the design requirements to ensure the safe operation of equipment inside the clean room.

• After the installation of the clean room is completed, acceptance and commissioning should be carried out to ensure that the normal operation of the system to achieve the desired clean effect.

Aerodynamics

The first thing to consider in the design of a clean room is its aerodynamic properties, which involves key indicators such as air velocity, number of air changes and static pressure. Air velocity is the key parameter to measure the speed of airflow inside the clean room, which directly affects the suspension and migration of particles. The number of air changes determines the freshness of the air inside the clean room, while the static pressure difference is the key to ensure that the pressure inside and outside the clean room is balanced to prevent the entry of external pollution.

Noise

Noise is an important part of clean room testing because excessive noise levels not only affect work efficiency, but may also adversely affect the health of staff. Therefore, the noise limit of the clean room should strictly follow the relevant health standards and be controlled through the use of appropriate sound insulation materials and technical means.

Illumination

Clean room illumination requirements are closely related to the purpose of its use, according to the actual needs of the work and the use of the environment to determine. Appropriate illumination not only ensures the visual comfort of the operator, but also ensures product quality. Commonly used light sources include incandescent lamps, fluorescent lamps and LED lamps, etc., which have their own advantages and disadvantages and need to be considered comprehensively when choosing.

Detailed description of testing items

• Wind speed and uniformity test: Through specific experimental equipment, such as anemometers, to determine the wind speed and its uniformity in the clean room, to ensure that the airflow distribution is reasonable.

• Test system or room airflow: Test the total airflow and fresh airflow in the clean room to ensure sufficient air supply to maintain a clean environment.

• Internal Cleanliness Check: Using tools such as particle counters, test the cleanliness level of the air inside the clean shed to ensure that there are no excessive particles present.

• Determine self-cleaning time: When internal contamination occurs, check the self-cleaning ability of the cleanroom, i.e. the time it takes for the purification membrane to return to its original clean state.

• Air flow detection: monitor the air flow in the clean shed to ensure that air circulation meets the design requirements.

• Noise detection: Use sound level meter and other equipment to detect the noise level in the clean room to ensure that it is within the safe range.

• Lighting Inspection: Use illuminance meter to detect the lighting level and uniformity in the clean room to ensure sufficient light.

• Vibration check: Using vibration sensors, check the vibration amplitude inside the clean room to ensure stability.

• Temperature and humidity detection: Using a thermohygrometer, detect the temperature and humidity inside the clean room to ensure appropriate environmental conditions.

• Total air volume and fresh air volume test: Detect the total air volume and fresh air volume in the clean room to ensure the freshness and cleanliness of the air.
