• Frame Material

  The frame of the clean room is usually made of industrial aluminum profiles, stainless steel squares or sprayed iron squares as materials, which are strong, beautiful, non-rusting and non-dust-producing. Aluminum profiles are widely used because of their good ductility and corrosion resistance, while stainless steel squares are used in wet or corrosive gas-containing environments because of their high strength and corrosion resistance.

• Wall Material

  The wall materials of the clean room are various, and the common ones are anti-static drape, acrylic board, tempered glass, etc. Among them, the anti-static drape is not only used in the clean room, but also in the clean room. Among them, anti-static curtains can not only effectively prevent the accumulation of static electricity, but also provide good transparency to ensure that the staff's line of sight. Acrylic panels and tempered glass provide additional physical protection and are suitable for applications that require a certain degree of robustness.

• Ceiling Materials

  The roofs of clean booths are often made of anti-static transparent materials, such as polycarbonate sheets or other anti-static plastic sheets, which can ensure sufficient strength and provide good light transmission while meeting the needs of anti-static.

• FFU Fan Filter Unit

  FFU (Fan Filter Unit) is an important part of the clean room, which is responsible for providing continuous clean air flow.FFU usually adopts centrifugal fan, which has the characteristics of long life, low noise, maintenance-free, small vibration, etc., and can adjust the wind speed by stepless speed change to adapt to different clean needs.

Classification and characteristics of clean room

Clean shed can be divided into two categories according to the use of industrial clean room and biological clean room. Industrial clean room mainly control inanimate particles on the contamination of the work object, commonly used in precision machinery, electronics, aerospace and other industries. Biological clean room focuses on the control of microorganisms and dust contamination of the work object, suitable for medicine, biotechnology and other fields.

The clean shed is characterized by its modular structural design, easy to install and dismantle, and can quickly build the required clean environment. Its internal purification level can reach class 100-100,000, and the cleanliness of the air is ensured by fan filter units (FFU) and a highly efficient filtration system.

Areas of application for clean rooms

• Electronic manufacturing industry: in the SMT production line, chip packaging, PCB assembly, etc., clean booths are used to prevent dust from affecting the performance of electronic products.

• Biomedical industry: in the production of drugs, microbial culture, cell culture, etc., clean shed to provide aseptic operating environment to ensure production quality.

• Food industry: In food processing and packaging, clean rooms help to meet GMP standards and improve food safety.

• Laboratories and operating rooms: When conducting delicate experiments or surgical operations, clean booths ensure the cleanliness of the environment to avoid contamination.

• Other industries: such as optics, new materials, fine chemicals, etc., all rely on clean booths to maintain the required production environment.

Advantages of Clean Sheds

Compared with the traditional clean room, the clean room has the advantages of less investment, shorter construction period, lower operating costs, easy to move and reuse. Its modular design allows the clean room to be customized according to different needs, whether used individually or in combination, can quickly respond to changes in various work scenarios.

Preparation before installation

Before installing a clean shed, the installation environment needs to be thoroughly cleaned and disinfected to reduce the level of dust and bacteria in the air and to ensure basic cleanliness conditions. In addition, all necessary materials and tools should be prepared, such as clean shed frames, filters, sealing materials, screwdrivers, leveling scales, etc. The environment and conditions at the installation site should also be checked to ensure that there are no disturbing factors, such as dust, wind and vibration.

Installation steps

• Installation environment preparation: Choose a dry, ventilated and well-lit environment for installation, avoid direct sunlight. At the same time, ensure that the construction area has enough space to accommodate the clean room and related equipment.

• Assemble the frame: according to the clean room program drawings, determine the installation location and size requirements, and then start assembling the frame and support structure, usually using aluminum alloy profiles to ensure that it is stable and reliable.

• Installation of high-efficiency filter and FFU fan: first install the high-efficiency filter, then install the FFU fan in accordance with the specified position, and connect the power supply, the FFU fan is one of the most important components in the clean room, responsible for generating a strong airflow, to ensure that the air circulation.

• Installation of ceiling and wall panels: Use purification boards or other materials that meet the cleanliness requirements to ensure the flatness of the ceiling and wall panels, and tight seams to avoid loopholes.

• Installation of lighting and electrical system: The clean room should be equipped with lighting system, including LED lamps and lanterns. When installing, the waterproof and dustproof performance of the lamps and lanterns as well as the uniformity of illumination should be ensured. The electrical system should comply with relevant national standards and industry requirements to ensure stable and safe power supply.

• Grounding treatment: The grounding treatment of the clean shed should meet the design requirements to ensure the safe operation of the equipment inside the clean shed.

• 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.

Precautions

• Avoid installing the clean room in dusty, humid or salty places.

• Clean the dust on the surface of the frame, FFU fan, plexiglass, etc. during installation.

• Installers should wear dust-free clothing, depending on the requirements.

• The installation process of the clean shed needs to be carried out in strict accordance with the regulations to ensure that the clean shed can provide a high-quality clean environment.

• Cleanliness Testing

  Cleanliness testing is a key step in evaluating the performance of a clean room and involves a number of parameters, including air velocity, static pressure difference, suspended particles, temperature, relative humidity, noise, illumination, and settled bacteria. The testing period is usually 7 working days, and the cost and validity of the report will depend on the specific situation. The testing process generally includes signing a contract, arranging on-site sampling, laboratory testing and issuing a test report.

• Clean room interior decoration requirements

  The indoor decoration requirements of the clean room are equally important, the decoration materials need to be airtight, small deformation, and the concentration of pollutants in accordance with national standards. Wall and ceiling decoration should be flat, smooth, dust-free, and reduce the concave and convex surface. Ground decoration should be flat, wear-resistant, easy to clean, and not easy to accumulate static electricity. In addition, the colors in the clean room should be light and soft, and the combustion performance of the decoration materials must comply with national standards.
