1、 Complete Analysis of Core Technologies for Cleanliness Control
1. Air filtration system
a. ISO Class 1 to Class 3 cleanrooms: High efficiency primary, medium, and high-efficiency air filters are key. These filtration systems can effectively remove particles and bacteria from the air, ensuring the air quality of the clean room.
b. ISO Class 4 to 9 cleanrooms: In addition to efficient air filtration systems, more advanced air purification technologies such as electrostatic precipitators and activated carbon adsorption are also required to further improve the cleanliness of the air.
2. Air flow control
a. Reasonable airflow design: Based on the requirements of the clean room, design a reasonable airflow direction and velocity to reduce the diffusion of particles and bacteria in the air.
b. Air circulation system: Maintain air circulation and renewal in the clean room through efficient fresh air and air circulation systems.
3. Selection of cleanroom materials
a. Materials for walls, floors, and ceilings should be selected that are not prone to dust accumulation and are easy to clean.
b. Furniture and equipment should be made of dust-free, oil-free, and easy to clean materials to reduce pollution to the clean room.
4. Personnel management
a. Personnel access management: Reduce personnel pollution to the clean room through measures such as changing clothes, showering, and air shower.
b. Personnel operating standards: Establish strict operating standards to reduce the impact of personnel activities in clean rooms on air quality.
5. Environmental monitoring system
a. By installing equipment such as air quality monitoring devices and temperature and humidity meters, the air quality and environmental parameters of the clean room can be monitored in real time.
b. Through an automated control system, the air filtration system, air circulation system, and other equipment are automatically adjusted based on monitoring data to maintain the air quality and environmental parameters of the clean room within a reasonable range.
2、 Testing data
Here are some cleanliness testing data for reference:
1. ISO Class 1 to Class 3 cleanrooms: particle count (≥ 0.1μ m) less than or equal to X per cubic meter (specific values vary depending on different standards and requirements).
2. ISO Class 4 to Class 9 cleanrooms: In addition to meeting the particle counting standards mentioned above, stricter microbiological and chemical pollutant control standards must also be met. Specific values can be tested and evaluated by professional testing institutions.
The above information is for reference only. Specific technical details and testing data need to be understood and confirmed in detail based on the actual situation and technical standards of Huajian Clean Room. For more information, it is recommended to contact Huajian Cleanroom directly or visit their official website for more detailed technical documentation and testing data.
