Material Overview

Materials typically used in clean rooms include, but are not limited to, industrial aluminum profiles, stainless steel squares, iron squares, cold rolled steel sheets, stainless steel sheets (e.g., SUS201, SUS304, SUS316, etc.), and FFU fan filtration units. The selection of these materials is designed to meet the needs of the clean room in terms of corrosion resistance, dust resistance, high temperature resistance, easy processing and high strength.

Specific material details

• Acrylic sheet

  Acrylic sheet is widely used for its excellent light transmission and chemical resistance. It has a transmittance of up to 92%, which can effectively transmit light while maintaining good visual clarity. In addition, acrylic sheet has good aging and abrasion resistance, making it suitable for long-term use.

• Aluminum profiles and stainless steel squares

  Aluminum profiles and stainless steel squares are commonly used to build the frames of clean booths. They not only provide sufficient strength and stability, but also maintain structural integrity in a variety of environments due to their good corrosion resistance.

• FFU (Fan Filter Unit)

  The Fan Filter Unit (FFU) is an important part of the clean room and is responsible for providing a continuous flow of clean air.FFUs are usually equipped with high efficiency HEPA filters to capture small particles and ensure air quality.

• Other Materials

  In addition to the above materials, clean rooms may contain special materials such as anti-static drapes, anti-static mesh curtains, etc., to enhance their anti-static properties and to meet specific cleanliness requirements.

• Selection of Clean Room

  When choosing a clean room, it is common to choose different levels of clean rooms for different cleanliness needs. Most customers will choose a class 10,000, class 1,000 or even class 10 clean room according to their needs. For example, in industries such as semiconductor and electronics manufacturing, the product manufacturing process has extremely high requirements for environmental cleanliness, so in these cases a Class 100 or higher cleanroom is usually chosen.

• Advantages of clean rooms

  The advantages of clean rooms are their fast construction speed, easy installation, low cost and easy maintenance. Because clean rooms are often modular, they can be easily assembled and disassembled, making them useful in situations where frequent changes to the production environment are required. In addition, clean booths can be equipped with universal wheels to allow for easy movement and repositioning, increasing their utility and flexibility.

• Disadvantages of clean rooms

  Despite the many advantages of clean rooms, there are some potential problems. Due to the large number of fan filtration units (FFUs) used, clean booths can be noisier and require more frequent maintenance. In addition, due to space constraints, the interior of a clean room can feel stuffy, which can affect staff comfort and productivity.

• Preparation before installation

  Before starting the installation, the construction area needs to be cleaned and sanitized to ensure that the floor is level and free of debris and dust. At the same time, make sure that the construction area has enough space to accommodate the clean room and related equipment. In addition, prepare the required tools and materials, such as lifting equipment, cleanroom materials, measuring tools, protective tools, etc.

• Installation of frames

  According to the design and specifications of the cleanroom, install the brackets and frames to ensure that the brackets are vertical and horizontal, stable and reliable. Frames are usually made of steel or aluminum alloy and need to be assembled and installed according to the design requirements.

• Installation of walls and ceilings

  Using special materials such as purification boards and stainless steel plates, install the walls and ceilings of the clean shed to ensure their flatness and tight seams to avoid any loopholes.

• Installation of doors and windows

  Install doors and windows according to the design of the clean room, and use sealing materials to ensure their sealing performance and prevent air leakage.

• Installation of filtration system and FFU fan

  Select the appropriate filter type and specification and install it on the top or side of the clean room, making sure that the installation position and direction of the filter is consistent with the direction of airflow. Then, install the FFU fan and connect the power supply to ensure its normal operation.

• Installation of lighting and ventilation equipment

  According to the use requirements of the clean room, install suitable lighting equipment, such as clean lamps, explosion-proof lamps, etc., and ensure that the illumination, uniformity and stability of the lighting equipment meet the production requirements. At the same time, install ventilation equipment, such as exhaust fans, air conditioners, etc., to regulate the temperature and humidity in the clean room.

• Commissioning and Testing

  After the installation is completed, comprehensive testing and debugging work is carried out, including checking the air quality, cleanliness, temperature and humidity and other parameters in the clean room to ensure that the systems operate normally and achieve the expected clean effect.

• Maintenance and upkeep

  Regular inspection and maintenance of the clean room, timely cleaning of filters and discharge of pollutants to ensure its long-term stable operation.

• Airborne particles: detects the level of particles in the air inside the cleanroom to ensure that it is within the specified cleanliness level.

• Temperature and Humidity: Monitors the temperature and humidity inside the cleanroom to ensure they are in optimum working condition.

• Fresh Air Volume: Checks whether the supply of fresh air volume is sufficient to maintain the air quality inside the clean room.

• Differential Pressure: Checks the differential pressure between the clean room and the outside world to ensure that the clean room is closed.

• Airflow status: Evaluates whether the airflow is evenly distributed to prevent dead-end areas.

• Noise level: Measure the noise level inside the clean room to ensure the comfort of the operating environment.

• Illumination: Detects the illumination level inside the clean room to ensure sufficient brightness to meet visual requirements.

• Static electricity and ion generator: Detect the effect of static electricity control and the effectiveness of ion generator.
