Production of new energy car in clean room
It is understood that a complete car has about 10,000 parts, of which about 70% are carried out in the clean room (dust-free workshop). In the car manufacturer’s more spacious car assembly environment, the oil mist and metal particles emitted from the robot and other assembly equipment will...Read more -
Requirements of medical clean room
The first point of clean room design is to control the environment. This means ensuring that the air, temperature, humidity, pressure and lighting in the room are properly controlled. The control of these parameters needs to meet the following requirements: Air: Air is one of the most important f...Read more -
