Vacuum applications 2024-06-21

With the development of vacuum technology, vacuum applications are increasingly expanding to various aspects of industry and scientific research. Vacuum application refers to the use of the physical environment of rarefied gases to accomplish specific tasks. Some use this environment to manufacture products or equipment, such as light bulbs, electronic tubes, and accelerators. These products maintain a vacuum throughout their use; Others only consider vacuum as a step in production, and the final product is used in the atmospheric environment, such as vacuum coating, vacuum drying, and vacuum impregnation.

The degree of gas rarefaction is an objective measure of vacuum 2024-06-21

The degree of gas rarefaction is an objective measure of vacuum, and the direct physical measure is the number of gas molecules per unit volume. The lower the density of gas molecules, the lower the gas pressure, and the higher the vacuum. However, due to historical reasons, measuring vacuum is usually expressed in terms of pressure. Pascal or Torr are commonly used as units of pressure in vacuum.

Introduction to Vacuum Technology 2024-06-21

Vacuum technology is the technology required to establish a physical environment below atmospheric pressure, as well as to conduct process manufacturing, physical measurements, and scientific experiments in this environment. Vacuum technology mainly includes four aspects: vacuum acquisition, vacuum measurement, vacuum leak detection, and vacuum application. In the development of vacuum technology, these four aspects of technology are mutually reinforcing.
