• Frame Material

  The frame of the clean shed is usually made of industrial aluminum profiles or stainless steel squares. These materials have good corrosion resistance and stability, which can ensure the solidity and beauty of the structure, and at the same time avoid the problem of rusting. Among them, aluminum profile has become one of the preferred materials for the frame of clean shed due to its light weight, high strength and corrosion resistance.

• Wall Material

  Wall materials are usually anti-static drapes or acrylic panels, which have high transparency, clear grid structure, and good flexibility and durability. They are not easy to be deformed or aged, and can effectively prevent the intrusion of dust and microorganisms to maintain the cleanliness inside the clean room.

• FFU Material

  FFU (Fan Filter Unit) is an important part of the clean room, it adopts centrifugal fan, which has the characteristics of long life, low noise, maintenance-free, and low vibration. the design of FFU allows stepless speed change, and usually equipped with high-efficiency air filters, which can realize the filtration efficiency as high as 99.99%, to ensure the purity of the air.

• Top Material

  The top of a cleanroom is usually covered with a close-seam blind and used in conjunction with an FFU to achieve the required level of cleanliness. The choice of material for the top is also very critical. Commonly used are anti-static curtains or anti-static plexiglass, which can effectively prevent the accumulation of static electricity and reduce dust adsorption.

• Characteristics of clean room

  The clean shed is characterized by its assembled structure design, easy and quick installation and short delivery cycle. It is highly flexible and can be customized in terms of size and cleanliness level according to actual needs. In addition, the clean shed has the advantage of energy saving and environmental protection, using energy-saving materials and design to reduce energy consumption. In terms of maintenance, it is easy to maintain due to its simple structure, which reduces the operation cost in the later stage. The clean shed can also be configured with universal wheels as needed, which is easy to move and adjust the position to adapt to different production needs.

• Application of clean room

  Clean room is widely used in electronics, medicine, food, biopharmaceuticals, laboratories and other fields, especially in the need for a high degree of cleanliness of the environment of the experiments, production and other aspects play an important role. In the electronics industry, clean booths are used in the production, testing, maintenance and other aspects of electronic products; in the pharmaceutical industry, for pharmaceutical production, experiments, inspection; and in the food industry, for food production, packaging, storage and other aspects. In addition, clean booths are also widely used in various laboratories to provide the necessary clean environment for scientific research.

• Installation Location

  Clean booths should be installed in a dry, ventilated and well-lit environment, avoiding direct sunlight. At the same time, the installation location needs to meet the additional requirements of the specific industry, such as anti-static, anti-corrosion and so on.

• Foundation construction

  Foundation construction should meet the design requirements to ensure that the foundation is level, solid and horizontal. Acceptance is required after construction, and the installation can be continued only after passing.

• Frame installation

  The frame is made of steel profiles, and the verticality and horizontality should be ensured during installation. After the frame installation is completed, anti-corrosion and anti-rust treatment should be carried out.

• Ceiling and wall plate installation

  The roof and wall plate should be made of purification board or other materials that meet the cleanliness requirements. When installing, ensure flatness and tight joints to avoid loopholes.

• Air purification system installation

  The interior should be equipped with an air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps and so on. When installing, make sure the components are connected tightly to avoid air leakage.

• Lighting System Installation

  The interior should be equipped with a lighting system, such as LED lamps and lanterns. When installing, ensure the waterproof and dustproof performance of the lamps, as well as the uniformity of illumination.

• Electrical system installation

  The electrical system should comply with national standards and industry requirements. When installing, make sure the power supply is stable and safe, as well as the normal operation of each electrical equipment.

• Grounding treatment

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

• Acceptance and debugging

  After the installation is completed, acceptance is carried out. After acceptance, debug the clean room to ensure the normal operation of each system and achieve the expected clean effect.

The Importance of Clean Room Testing

Clean room testing is critical to ensuring product quality. It involves not only the cleanliness of the air inside the clean room, but also temperature and humidity, noise, static pressure difference and other aspects. The testing of these parameters ensures the stability and controllability of the environment inside the clean room, which in turn affects the accuracy and efficiency of production.

Clean room testing standards and parameters

• Temperature and humidity: According to different production and scientific research requirements, the temperature and humidity inside the clean room should be controlled within a certain range.

• Air Suspension: The concentration of suspended particles in the air inside the clean room is tested to ensure the cleanliness of the production environment.

• Fresh air volume: The test of fresh air volume is to ensure that there is enough fresh air entering the clean room to maintain good air quality.

• Pressure difference: Check the pressure difference between inside and outside the clean shed as well as each functional area to ensure the closure and cleanliness of the internal environment of the clean shed.

• Airflow status: check whether the airflow status in the clean shed meets the design requirements to ensure the rationality and uniformity of air flow.

Methods and techniques of clean room testing

• Planktonic bacteria sampling method: the use of air samplers to capture the air in the planktonic bacteria, and then culture counting.

• Dust sampling method: Capture airborne particles and dust through specialized equipment to determine the cleanliness level.

• Sedimentation bacteria sampling method: In the clean shed placed on a petri dish to collect sedimentation bacteria, through culture analysis to determine the cleanliness of the air.

• Sound Level Test: Use a sound level meter to check the noise level in the clean room to ensure that it does not exceed the specified standard.

• Illumination test: Use the illuminance meter to test the light intensity in the clean room to ensure sufficient lighting.
