• Material Characteristics

  Clean booths are usually covered with highly transparent plastic film, which not only provides good visual permeability, but also effectively prevents the intrusion of dust and particles. For example, some models of clean booths use transparent PVC material, the surface of which has been specially treated to provide excellent anti-static properties, which can effectively release the accumulated electric charge and prevent static electricity from causing damage to sensitive components.

• Anti-static performance

  In order to achieve the anti-static effect, the outer surface resistance of the cleanroom is usually controlled within the range of 10^4Ω-10^6Ω, while the outer surface resistance of the meshless part is between 10^8Ω-10^10Ω. Such design can ensure enough conductivity to discharge static electricity without affecting the use.

• Specification

  The specifications of clean booths are generally 0.3mm, 0.5mm or 1.0mm thick and up to 1370mm in length, which are suitable for different application scenarios and needs. For example, certain specifications of anti-static mesh curtains can be up to 0.3mm1.37m30m in length, providing sufficient coverage area to suit the needs of clean environments of all sizes.

• Structure and Function

  The clean room is usually composed of an aluminum alloy frame and anti-static curtains, and is equipped with a fan-filter unit (FFU) and special purification lamps, which can realize air circulation filtration and purification. Its internal purification level can reach 100-100K, especially suitable for those areas that require high local cleanliness, such as assembly line operation areas.

• Application Scenario

  Clean room is widely used in electronic manufacturing, biopharmaceutical, food processing, medical equipment and other fields. In the electronics industry, the clean room can prevent the contamination of sensitive components by fine dust and ensure product quality. In the field of medical and health care, clean booths are mainly used in operating rooms and sterile wards to provide a cleaner and safer environment for patients.

• Advantageous Features

  The main advantage of a clean room is its quick setup, easy mobility and reusability. It can be installed in a short period of time and can be used individually or in combination as required. In addition, the modular design of the Clean Shed makes it easy to increase cleanliness levels and is also highly scalable.

• Contamination Control

  The clean room is also very well designed in terms of contamination control. For example, dust generated by the equipment can be removed through the local exhaust system to avoid contamination spreading into the room. Meanwhile, considering the influence of material, style and activities on the amount of dust generated, the clean shed interior adopts a highly efficient filtration system and reasonable air circulation design to ensure the cleanliness of the work area.

• Installation Environment Preparation

  Before starting the installation of a clean shed, the installation environment needs to be cleaned and sanitized to reduce the level of dust and bacteria in the air and to ensure basic cleanliness conditions.

• Assembling the frame

  According to the clean room program drawings, determine the installation location and size requirements, and then begin to assemble the frame and support structure. Aluminum alloy profiles are usually used to ensure a solid and reliable structure. If the clean room is large, additional support points are required in the center to ensure safety.

• Installation of high efficiency filters and FFU fans

  Firstly, install the high efficiency filter to ensure that it can effectively remove fine dust and bacteria in the air to ensure that the cleanliness level inside the clean room meets the standard. Then install the FFU fan in the specified position and connect the power supply, the FFU fan is one of the most important components in the clean room, it can generate strong airflow to ensure air circulation.

• Installation details

  Install sealing materials, such as sealing strips and gaskets, around the perimeter of the clean shed and at openings such as doors and windows to ensure good sealing. At the same time, install the internal lighting system and electrical system to ensure the power supply is stable and safe, as well as the normal operation of each electrical equipment.

• Debugging and Testing

  After completing the above steps, it is necessary to debug the clean room to ensure that the FFU fan is running normally, the filter is working well, and check whether there is any air leakage or other problems inside the clean room. Use professional testing instruments to test the air quality in the clean room to ensure that the cleanliness, temperature, humidity and other parameters meet the requirements.

• Use and Maintenance

  When using the clean room, we should avoid installing it in dusty, humid or salty places. Regular inspection and maintenance of the clean room should be carried out to clean the filters and discharge pollutants in a timely manner. In addition, particle counters should be used regularly to test the cleanliness of the clean room to ensure that it meets the technical requirements.

Filter Leak Testing

• Inspection of Damaged Filters: Confirms the presence of physical damage to the filter, such as perforations or tears, which could lead to contaminant leakage.

• Inspection of filter-to-frame gaps: Meticulously inspect the gaps between the filter and the frame to ensure that they are well sealed and that there are no visible gaps to prevent contaminants from entering the clean area through these gaps.

• Inspection of other parts of the filter unit: In addition to the filter and outer frame, other potential vulnerabilities of the filter unit, such as fixings, seals, etc., need to be inspected to ensure the integrity of the overall structure.

Isolation Leak Detection Test

Isolation leakage testing is done to prove that suspended contaminants do not pass through the building materials into the cleanroom. This usually involves checking the airtightness of the cleanroom envelope to ensure that it is effective in isolating contaminants from the outside world.

Indoor Airflow Control Testing

The purpose of airflow control testing is to ensure that the airflow in a cleanroom meets the design requirements, which are usually categorized into two types: turbulent flow and unidirectional flow. In the case of a turbulent flow cleanroom, it is necessary to verify that there are no areas of insufficient airflow within the room, while in the case of a unidirectional flow cleanroom, it is necessary to ensure that the air velocity and direction throughout the room meets the design requirements.

Suspended Particle Concentration and Microbial Concentration Tests

These tests are used to confirm that the cleanliness of the cleanroom is up to standard. During the tests, specialized instruments are used to measure the number of suspended particles and the concentration of microorganisms in the air to verify whether the cleanroom can effectively inhibit the accumulation of contaminants.

Other Tests

In addition to the above tests for contamination control, tests such as indoor temperature, relative humidity, indoor heating and cooling capacity, noise level, light level, and vibration value are sometimes required. These tests help to comprehensively evaluate the overall performance of the clean room to ensure that it can operate stably in various environments.
