Frame Material

• Stainless Steel Frame

  Stainless steel frames are the preferred material for cleanroom frames due to their excellent corrosion resistance and mechanical properties. The smooth, burr-free surface of stainless steel reduces the possibility of microorganisms adhering to the frame, which in turn improves the overall cleanliness of the cleanroom. In addition, stainless steel has high strength, is resistant to high temperatures, and is not prone to releasing harmful substances, which meets the needs of a clean environment.

• Aluminum Frame

  Aluminum is widely used in clean rooms for its light weight and good thermal conductivity. However, due to its susceptibility to corrosion and scratches, the surface is rougher and less convenient to clean than stainless steel. Nonetheless, aluminum is still an economical and practical choice due to its relatively low price.

Main Material

• PVC anti-static material

  PVC material is considered for its good insulation and corrosion resistance. However, PVC material is prone to static electricity and adsorption of particulate matter, so special attention needs to be paid to its anti-static properties and abrasion resistance when using it in cleanrooms. The use of PVC anti-static material can effectively maintain the cleanliness of the clean room.

• Glass

  Glass material has excellent flame retardant and insulating properties, and can effectively block the spread of bacteria. However, its surface is vulnerable to scratches, and the sealing is not as good as metal, so it is usually used with double-layer tempered glass as the enclosure to ensure the cleanliness and strength of the clean room, and also enhance the appearance of the texture.

Technical parameters and characteristics

The technical parameters of the clean room mainly include the purification level, average wind speed, noise level, power supply specifications and so on. The purification level can reach 100 to 300,000 levels, the average wind speed is generally between 0.25-0.45m/s, the noise level is controlled below 58dB(A), and the power supply is mostly 220V 50HZ.

• Assembled structure design: easy to install, short delivery cycle, can quickly build up a clean environment.

• Convenient movement: the bottom is equipped with universal wheels, which is convenient for position adjustment and migration of the clean shed.

• Modularized design: Modules can be added or reduced according to the demand, easy to improve the cleanliness level, strong expandability, and high reuse value.

• Economical and practical: Compared with the traditional clean room, the construction cost of the clean room is low, the construction speed is fast, and the height requirement of the floor is not high.

Application Fields

Clean room is widely used in electronics, medicine, food, laboratory and other fields, especially suitable for those who need local high cleanliness occasions. In the electronics industry, clean room can be used for electronic production, testing, maintenance and other links; in the pharmaceutical industry, it is commonly used in drug production, testing, inspection, etc.; and in the food industry, clean room is served in the food production, packaging, storage and other processes. In addition, laboratory research activities also need to rely on the clean environment provided by the clean room.

• Preparation before installation

  Before installing the clean shed, it is necessary to survey the installation environment, develop the construction program, prepare the construction materials and equipment, and train the construction personnel to ensure that they have the appropriate skills and qualities.

• Foundation construction

  The foundation construction of the clean shed should be in accordance with the design requirements to ensure that the foundation is level, solid and horizontal. After the foundation construction, acceptance should be carried out, and the installation of clean shed can be carried out only after passing.

• Frame installation

  The frame of the clean shed is made of steel, aluminum alloy or stainless steel, etc. When installing, the verticality and levelness of the frame should be ensured, and anti-corrosion and anti-rust treatment should be carried out.

• Ceiling and wall plate installation

  The ceiling and wall plate should be made of purification plate or other materials that meet the clean requirements. When installing, the flatness of the ceiling and wall plate and the tightness of the joints should be ensured to avoid any loopholes.

• Air purification system installation

  The interior of the clean shed should be equipped with an air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps and so on. When installing, it should be ensured that the connection between components is tight to avoid air leakage.

• Lighting system installation

  A lighting system, including LED lamps and lanterns, should be installed inside the clean room. When installing, the waterproof and dustproof performance of the lamps and lanterns as well as the uniformity of illumination should be ensured.

• Electrical system installation

  The electrical system of the clean room should meet the relevant national standards and industry requirements. When installing, it should ensure the stability and safety of power supply, as well as the normal operation of each electrical equipment.

• Grounding treatment

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

• Acceptance and debugging

  Clean shed installation is completed, acceptance should be carried out. After acceptance, the clean shed debugging to ensure that the normal operation of the system to achieve the desired clean effect.

The importance of clean room testing

Clean room testing is used to confirm that the internal environment meets specific cleanliness requirements, which is particularly important for many high-tech industries such as semiconductors, microelectronics, and pharmaceuticals. In these industries, the production and processing of products requires a very high level of environmental cleanliness, and any small particles can lead to product defects or failures. Therefore, the clean room inspection can help manufacturers to ensure the cleanliness of the production environment, and thus ensure product quality.

Methods of clean room testing

• Empty state test

  Empty state test refers to the clean shed has been completed construction, purification and air conditioning system is in normal operation, but there is no process equipment and production personnel in which the situation of the test. This kind of test mainly focuses on the physical characteristics of the clean room, such as air volume, air speed, positive pressure, temperature, humidity and so on.

• Static Testing

  Static testing is a test in which process equipment is installed in the clean room, but no production personnel are present. At this time, the working status of the equipment and the cleanliness inside the clean room will be tested to ensure that the equipment is running normally and the cleanliness is up to standard.

• Dynamic Testing

  Dynamic testing is the closest test to the actual production situation, when not only the process equipment is running in the clean room, but also the production personnel are operating. This test is designed to simulate the actual production environment and detect the cleanliness performance of the clean room in actual operation.
