The main function of chemical companies is to control the cleanliness, temperature and humidity of the atmosphere in which products (such as silicon wafers) come into contact, so that products can be manufactured in a good environmental space, which is the basis of pollution control. It is defined as a room with materials and devices for air filtration, distribution, optimization and construction.
Purification engineering is also a basic supporting industry, which is widely used in many industries, such as electronic information, semiconductors, optoelectronics, precision manufacturing, medicine and health, bioengineering, aerospace, automobile painting and so on.
Extended data
Purification is an engineering discipline that removes particulate matter, harmful air, bacteria and other pollutants from the air in a certain space, and controls indoor temperature, cleanliness, pressure, airflow speed and airflow distribution, noise and vibration, lighting and static electricity within a certain demand range. The room specially designed for the purification project has the performance of maintaining the original required cleanliness, temperature, humidity and pressure no matter how the external air conditions change.
Control the cleanliness and temperature and humidity of the atmosphere where products (such as silicon wafers) come into contact, so that products can be manufactured in a good environmental space. The design and construction process of this space can be called purification project.
