The clean room of purification workshop should meet the requirements of product production process and air cleanliness level. Generally according to the product production process deployment, people flow, logistics route is short, equipment is meticulous, to comply with the relevant fire safety, health regulations. According to the manufacturing process of different products, different air cleanliness classification plans are reasonably determined. If there are other differential pressure requirements, a clean zoning plan should be determined according to the differential pressure requirements of other production rooms.
The clean room is only equipped with the process equipment needed for the production of products and the process and studio with air cleanliness level requirements. The purpose of this is to minimize the area of expensive and expensive operating rooms. For this reason, generally, the production process, process equipment, studio and public power facilities without cleanliness level requirements are set in improper rooms.
Clean room design should first understand the purpose, use and production process characteristics of the designed clean room. For example, in order to design a clean workshop for IC production, it is necessary to master the characteristics of product integration, special size and production process. The requirements for clean room include air cleanliness grade, temperature and humidity, control range, micro vibration prevention, static electricity prevention, high purity material supply requirements, etc.
Determine the air cleanliness level of various production processes (rooms) and various control parameters, temperature, relative humidity, differential pressure, micro vibration, high purity substances, purity and impurity content. The air flow pattern of the clean room is preliminarily selected, and the preliminary estimation and design scheme of the purification air conditioning system are compared and determined. In order to make a clean plant layout and space layout, it is necessary to make a reasonable layout of product production area, production auxiliary area and power public facilities area. Generally, it is necessary to comply with the production process of the product, ensure the requirements of the production environment, and carry out the operation and management that is conducive to the production of the product, so as to save energy and reduce the production cost. During the layout of the clean room, it is necessary to comply with the requirements of the current national standards on safety in production, fire control, environmental protection and occupational health. In the clean room layout, we should fully consider the crowd and logistics layout, and strive to be fast and stable. When designing the space, we should fully consider the reasonable arrangement of the production process, various pipelines and logistics transportation in the clean room. After determining the plane and space layout of the clean room factory, put forward the design content, technical requirements and related problems in the design of the clean room.
