What is Vacuum Technology?
Vacuum technology involves the creation of a vacuum, a space where the pressure is significantly lower than atmospheric pressure. This is achieved by removing gas molecules from a sealed environment, typically using specialized equipment like vacuum pumps and chambers. The degree of vacuum achieved can vary, ranging from low vacuum (rough vacuum) to high vacuum and ultra-high vacuum (UHV), with each type having distinct applications in different industries.
Types of Vacuum Levels:
- Low Vacuum: Achieved by partial removal of air, typically used in industrial applications.
- Medium Vacuum: Common in processes like drying, degassing, and research that require moderate vacuum conditions.
- High Vacuum: Essential in the semiconductor industry, surface science, and materials testing, where extremely clean environments are necessary.
- Ultra-High Vacuum (UHV): Required in cutting-edge fields like particle physics, astronomy, and high-precision material sciences.
