The Core of Manufacturing -- Clean Room Technology and Application

A clean room is a closed space with specific cleanliness requirements. Mainly used to strictly control parameters such as air cleanliness, temperature, humidity, pressure, etc., to meet the needs of specific production processes or scientific research.

1.Functions and roles

Providing a sterile environment: In industries such as biomedicine and food processing, clean rooms can effectively prevent contamination by microorganisms such as bacteria and viruses, ensuring product quality and safety.

Control particle pollution: In fields such as electronic manufacturing and precision instruments, clean rooms can reduce particles in the air, preventing adverse effects on product performance and quality.

Maintain stable environmental conditions: By precise control of temperature, humidity, and pressure, provide a stable environment for production processes or experiments, ensuring product consistency and reliability.

2. Main components

Air purification system: including high-efficiency filters, fans, ducts, etc., used to filter particles and pollutants in the air, ensuring the cleanliness of the clean room air.

Air conditioning system: Adjust the temperature and humidity of the clean room to meet the requirements of different production processes or experiments.

Lighting system: Provide sufficient lighting intensity for staff to operate and observe.

Enclosure structure: composed of walls, ceilings, floors, etc., it has good sealing and insulation performance to prevent external pollutants from entering the clean room.

Control system: Monitor and control various parameters of the clean room to ensure that they are always within the specified range.

3. Classification of Cleanliness Levels

The cleanliness level of a clean room is usually classified based on the amount of suspended particles in the air. The international standard ISO 14644 classifies cleanrooms into different levels, ranging from the highest ISO level 1 to ISO level 9. The higher the level, the fewer particles in the air and the higher the cleanliness.

4. Application Fields

Biomedical: Used in drug production, cell culture, and vaccine development to ensure the sterility and purity of products.

Electronic manufacturing: To prevent particles from affecting the performance of electronic components in the production process of semiconductors, integrated circuits, flat panel displays, etc.

Food processing: Ensure food hygiene and safety, prevent contamination by microorganisms and foreign substances.

Precision instrument manufacturing: providing a clean environment for the production and assembly of high-precision instruments.

Research laboratory: meets the needs of various scientific research for a clean environment, such as research in the fields of biotechnology and nanotechnology.
